4 Most-Common Problems with Phantom 4 Pro V2 (Must-Read)

I have been flying drones for business purposes for 6 years now. When I first had the idea of a drone business, I did a lot of research. I wanted to learn the different platforms, the business opportunities, and the legal requirements and rules. I earned my Part 107 certificate before I started flying so that I was not outside of the rules and since I had not been involved in aeronautics in any way prior, that was quite an eye-opener. 

I began with the Phantom 3 Advanced and have crashed, traded, upgraded, and grown through 6 different aircraft, operating now with the Phantom 4 Pro V2 and I use my Phantom 4 Pro as my backup. 

While I love the Phantom 4 Pro V2, there are four issues that bother me, and they are not so much V2 issues as much as problems that the Phantom 4 Pro and most of the Phantom aircraft also share . 

• Obstacle avoidance infrared side sensors are only available in beginner mode and tripod mode and are not active all the time.
• The Phantom 4 Pro V2 lacks an obstacle avoidance sensor on the top of the aircraft.
• You need to test the accuracy of the obstacle avoidance system yourself, with the risk of crashing.
• The 12-volt battery charger you can plug into your vehicle takes an exceptional amount of time to charge one battery. 

Let’s work through these issues together.

1. Side sensor activation

If you’re new to the Phantom 4 Pro V2, you will soon discover what I’m talking about. The more experienced Phantom pilot has probably already found this annoying feature and has come to terms with it in some way or another. 

Getting into the programming of your aircraft you will marvel at the available settings for the hazard sensors. Now, DJI calls this their “Vision System” and the “Infrared Sensing System”. 

The vision system sensors are on the bottom, nose, and tail of the aircraft. The infrared sensors are located on both sides. There are control slide buttons within the programming and you can choose what to have on and off as your project dictates. 

If you are scheduling your flight to be in very confined spaces, you might need to turn off the vision system. Let’s say that you want to fly closer than 30 feet to a wall to do some detailed inspection. When the vision system is on, you will start to get a warning on the RC, and when you get within the established boundaries, the aircraft will stop dead where it is and not proceed another inch. 

This is very helpful for cinematic flying where you might want a sweeping fly-by of a hillside or ornate building, but if you need to get close in for a still shot that you will want to magnify, you need to turn off the vision system. Likewise, if you are flying into a tunnel, the lower alarm will beep and limit how low you can go. 

This is most frustrating for me when I am landing on the deck of my pickup and the aircraft is facing toward or away from the cab. The system will stop the AC from getting close enough until I either turn sideways or turn off the system before I can land. 

Side sensors in Beginner Mode

However, the big irritation is that the infrared side sensors cannot be turned on until you launch and put the drone into Beginner Mode or Tripod Mode. The “Beginner Mode” is not described in the user manual and can only be found while browsing through the control screen menu. You will find this option on the MC Settings page, 5 th item down on the list. 

It shows that “In Beginner Mode the aircraft can only fly within 30 radius of the Home Point at significantly slower speeds.” This is a very good idea for someone new to droning, and a great idea if you have not flown your $1500 V2 before. 

But if you are anything like the rest of us, by the end of the first battery you are ready for some real flying and you will turn off Beginner Mode. So why did DJI choose to make the infrared side sensors available in Beginner Mode? That answer is pretty obvious. 

As a new pilot who is just learning to fly you want all the protection and warnings available , but if you can only fly 30 radius (I am assuming that is 30 yards or 30 meters depending on how you have set your measurement units) that is close enough that you should be able to visualize any obstacles in any direction. 

As beginners, we are so focused on where the drone is going and we are watching it so closely that if we were to hear the controller beeping and light arcs on the screen glowing red, that may distract us from keeping visual line of sight. So I am not sure that the infrared side sensors are of much value in Beginner Mode. 

According to the User Manual, “In the Tripod Mode, the maximum flight speed is limited to 5.6 mph (9kph) and the braking distance is reduced to 6.6 ft (2m). Responsiveness to stick movements is also reduced for smoother more controlled movements”. 

It seems that the only time DJI feels the infrared side sensors are needed is when the drone is going slower than normal speeds. Also, you cannot start Tripod Mode until you are in the air, so you have to take extra steps to activate the infrared side sensors. 

However, I would like to be able to use the infrared side sensors in all the modes. If I am flying up a hillside in trees or other vegetation, the warning of an object to the side could be greatly appreciated. I have flown around the top of a hill several times where there was a temporary loss of sight of the aircraft. 

It sure would be nice if I had some confidence that I was not flying into something to the left or right. Another time I was flying through a gully with pine trees on both sides and climbed up in a cinematic shot. I had a clear line of sight to my drone, and I saw a tree just beyond the V2 but the drone was facing away and I could not tell how close to the right the tree was. 

Right about then, I could have used a warning because I moved an inch closer, caught a twig, and crashed to the ground. The V2 fell all the way to the bottom of the gully. It was a long hike down to get it, and some repairs were needed. 

Why DJI has decided to not program the infrared side sensors to operate for all flight modes is a mystery to me. I have contacted their helpline and chatted with an agent, but he said he did not have the answer to that and would send the question up line. 

2. Lack of top obstacle sensor

Another common issue with the Phantom 4 Pro V2 is that there is no sensor on the top of the drone. Why not? I would love to fly through a tunnel and not worry about rising just a bit too much, or fly down a forest path and be relieved of the danger of going too high. 

Again, DJI has made a design decision without really consulting the people who buy and fly their drones. 

3. Obstacle sensor sensitivity level

The range of hazard detection is stated in the manual as being between 50 and 70 degrees to each side of each sensor, depending on which sensor is in question. However, the distance of the hazard recognition is not mentioned in any instructions, so the only way to determine the accuracy of the signals is by testing it yourself.  

There are multiple variables to consider while testing and you should be aware of getting different results under different circumstances. For one thing, the surface of the object you are coming close to can cause distinct changes. A smooth cement wall will not be detected as soon as a wall of wood slats that have a rough or textured surface. 

A large boulder will show up before a street or paved road. Reflective surfaces register well but fences my not activate a warning at all. 

The only way to find the accuracy level of your V2’s obstacle avoidance system is by individual testing and experimentation. If at all possible, ask an observer to help out then go out and find several different surfaces to work with. 

Place your observer and yourself at different angles to the object and keep things low to the ground. Try testing against trees, bushes, structures, and ground areas. The speed you fly at can also change the distances that are detected. The faster you fly, the less space your aircraft has to respond. 

4. Battery life and charging

Generally, when you are out flying for business or recreation, you are using three different power sources. Naturally, everyone knows about the aircraft battery and you usually remember the RC battery, but many forget your tablet, iPad, or phone power levels. 

Although the user manual says that you can expect 30 minutes of flight time out of the drone batteries, that is highly dependent on several circumstances. To be safe, I usually calculate that each battery will give me 20 minutes of flight time if fully charged at take-off . 

Vertical and horizontal speeds can draw heavily and the power levels. Head- or tailwinds can change how quickly batteries decline. Fortunately, DJI has done a great job of including a massive amount of battery data right on the RC screen so that you can keep track of the situation. 

There are also several safety protocols in place in case you lose track of the power levels. You can set the alert limits within the menu but I generally use the 20% level as my warning and 10% as my auto Return To Home setting.  

When the battery reaches the point that there is only 20% power left, an automated warning activates, indicating the level. At the 10% level, the drone will automatically begin to land. 

Another safety feature activates when the aircraft calculates that there is just enough power to Return to Home. To be sure that I can complete almost any mission, I carry seven batteries in my kit.

The RC battery lasts longer than the aircraft batteries by a long shot, but it is not possible to slip in a charged battery once the RC gets low. In addition, when your screen device is plugged into the RC, the RC battery will transfer power to the screen. This drains the RC a bit faster and I have not found a method to shut that option off. 

Additionally, do not let the RC battery get below one bar of power. If the RC battery gets too low, an internal sensor will not allow you to recharge the battery fully. I can tell you from personal experience that just installing a new battery will not solve the problem. A whole new RC unit will be needed. 

Since the RC unit will use power to charge whatever screen you use, be sure that your screen is fully charged before leaving your home or office for a mission. iPad, tablet, and phone chargers are common and when plugged into your vehicle’s 12-volt system, charge pretty quickly. 

However, there are only two charging accessories available for the aircraft and RC batteries. The most commonly used is the home charger that plugs into your 110 volt home system. 

Many companies also make a rack that holds three drone batteries but only charges one RC. I have read a warning that recommends that you not charge the RC at the same time you are charging the drone batteries .  

The other device available is the car charger. However, it is very, very slow. When I am in the field, I cannot count on even one battery charging to 100% before I have used all 7 of my batteries. This all has to do with amperage, voltage, and many other electronic settings, but suffice to say that you should not rely on the car charger to keep your drone going for very long.  

I hope I have been able to enlighten the new Phantom 4 Pro V2 user on some issues with the drone. Each of these topics is a programming issue and I don’t know if there is anything that any one of us can do to solve them, but we always are moving forward with enjoying our flying. 

Hobby or professional, droning is great and the possibilities are endless.  Don’t make the mistake of thinking I don’t like DJI or my Phantom 4 Pro V2. I only buy DJI right now and until something of equal value and technology comes along, I will keep my fleet.

This page is part of IGN's Phasmophobia Wiki guide and details everything you need to know about a Phantom, including where a Phantom can usually be found, all unique strengths and weaknesses, as well as how to identify a Phantom.

What Is a Phantom and How to Find Them

A Phantom is a ghost that can posses the living, inducing fear into those around it. They are most commonly summoned from Ouija Boards.

Phantom Unique Strengths

Looking at a Phantom will drop your sanity considerably faster.

Phantom Weaknesses

Taking a photo of the Phantom will make it temporarily disappear.

How to Identify a Phantom and All Evidence

To use a Spirit Box , you must be nearby (3m) or in the same room as the Ghost and the lights must be off. Then, you will be able to speak to the Ghost and ask it questions from four different categories - Difficulty, Location, Age, and Personal. 50% of the time, Ghosts will be shy and will only respond on the Spirit Box if there is only one player nearby. Not all Ghosts will respond, but the Phantom is one that will. If it does, you have found another piece of Evidence .

Other possible Ghosts with Spirit Box Evidence: Mare , Onryo , Poltergeist , Spirit , The Twins , Wraith , Yokai

Fingerprints

Ghosts that interact with items or surfaces (such as opening a door) in a location will leave behind Fingerprints . You can use items like the UV Light or Glowstick to be able to find fingerprints throughout the map and to determine if a Phantom is the Ghost you're looking for.

Other possible Ghosts with Fingerprints Evidence: Banshee , Demon , Goryo , Hantu , Jinn , Myling , Obake , Poltergeist

D.O.T.S Projector

When mounted on a wall or the floor, the D.O.T.S Projector will cast a bright green laser grid made up of dots in the surrounding area. If a ghost crosses through the grid, their silhouette may appear as a faint, white figure passing through but is not a guarantee. The silhouette can also be seen through video cameras , so players tracking evidence such as Ghost Orbs from the video feed in the van can also see this.

Other possible Ghosts with D.O.T.S. Projector Evidence: Banshee , Goryo , Oni , Raiju , Wraith , Yokai , Yurei

Phantom 4 Advanced vs Phantom 4 Pro: 4 Differences You Need to Know

Update : The Phantom 4 Advanced and Phantom 4 Pro are no longer in production. For the latest in DJI technology, please view our products here .

DJI’s most recent release, the Phantom 4 Advanced , is a slightly altered version of the Phantom 4 Pro unit which came out late last year.

Its titanium and magnesium alloy makes the aircraft more durable than most others in the market, as well as light. With a maximum flight time of 30 minutes, users can get the most out of their drone. Though mostly the same as the Phantom 4 Pro, the Phantom 4 Advanced is designed with some tweaks that give consumers a more affordable yet still professional choice for aerial imaging.

Professional I maging

Like the Phantom 4 Pro, the Phantom 4 Advanced includes a camera with a 1″ 20 MP sensor that has close to 12 stops of dynamic range. It also has a mechanical shutter to eliminate rolling shutter effects from capturing fast moving subjects or images at high aircraft speeds. It can record 4K/60 fps video at 100 Mbps and offers H.265 video compression.

Professional Control

The DJI Phantom 4 Advanced comes with an optional controller that has an integrated high luminance display. This display monitor gives the users a live HD view from the main camera as well as essential telemetry data, even in direct sunlight. The new controller has a built-in GPS, compass, micro SD card slot and HDMI port. The drone with the standard remote controller is priced at $1,199 USD . The Phantom 4 Advanced +, which includes a Phantom 4 Advanced aircraft and the remote controller with an ultra bright display monitor is currently priced at $1,499 USD .

Intelligent Flight Modes

The Intelligent Flight Modes of the Phantom 4 Advanced give it the versatility and intuitiveness needed to aid professional aerial imaging. These include Draw, Gesture, an upgraded TapFly, Tripod, Terrain Follow and an upgraded ActiveTrack . To give you an idea of a few of these features:

Draw: Draw a route on your display monitor, and the Phantom 4 Advanced will move in that direction while holding its altitude constant. While Draw is activated, the pilot can keep attention on the camera focus and even the direction the camera is facing.

ActiveTrack: The Phantom 4 Advanced can recognize and track subjects while keeping them in frame. The upgrade is in the new algorithm used, that can recognize more objects and adjust the flight dynamics to ensure smoother flight.

Gesture Mode: The Phantom 4 Advanced can follow instructions for taking a selfie, through gestures. This allows users to get the perfect aerial shot of themselves while not having to focus on a remote controller and be distracted by buttons.

These are just some of the cool features of the Phantom 4 Advanced , that you will mostly find in the Phantom 4 Pro as well. What really differentiates it from the Phantom 4 Pro are the below key points.

Phantom 4 Advanced vs Phantom 4 Pro:  4 Differences You Need to Know

Flight Autonomy System

The Phantom 4 Advanced is only shy of the Phantom 4 Pro when it comes to obstacle avoidance. As we know the Phantom 4 Pro has 5-direction obstacle sensing. Three sets of visual systems to avoid obstacles in front, behind and below the aircraft, as well as an infrared sensing system on both sides. Phantom 4 Advanced keeps the obstacle sensor in front and below. It lacks back sensors and the infrared sensors on both sides. Otherwise, the flight systems are all the same.

Live View Working Frequency

With the the P4P you can choose between 2.4 GHz and 5.8 GHz to gain clearer signal stability in areas with high radio interference. The P4A does not support the 5.8 GHz frequency band.

The Phantom 4 Pro’s price is $1,499 USD with a standard remote controller. The Phantom 4 Pro+, which includes a Phantom 4 Pro aircraft, and a high luminance display remote controller, is available at $1,799 USD.

On the other hand, the Phantom 4 Advanced is priced at $1,199 USD  with a standard remote controller. The P4A+ retails at $1,499 USD .

With a weight of 20g, the Phantom 4 Advanced is lighter than the Phantom 4 Pro, while not affecting the impressive flight time.

Drone hits Moscow tower housing ministries for second time, says mayor

Russian defence ministry blames Kyiv for attack as Ukrainian presidential adviser says Kremlin should expect ‘more war’

• Russia-Ukraine war – latest news updates

A high-rise building in Moscow housing Russian government ministries has been hit by a drone for the second time in three days, the city’s mayor has said, as a Ukrainian presidential adviser said the Kremlin should expect more drone attacks and “more war”.

The Russian defence ministry said two drones were destroyed by air defence systems in the Odintsovo and Naro-Fominsk districts near Moscow in a fresh wave of attacks on Tuesday, while it claimed a third was jammed and went “out of control” before it crashed in the Moscow City business district, a cluster of glass skyscrapers that was built to show Russia’s growing integration into world financial markets. The ministry blamed Ukraine for what it called an “attempted terrorist attack”.

Photos and video showed that a drone had ripped off part of the facade of a modern skyscraper, IQ-Quarter, 3.4 miles (5.5km) from the Kremlin, which houses staff from several ministries, including Russia’s ministry of digital development, communications and mass media.

“The facade of the 21st floor was damaged. The glazing of 150 sq metres was broken,” the Moscow mayor, Sergei Sobyanin, said in a Telegram post, adding that no injuries had been reported.

Ukraine has not formally admitted it was behind the strikes on Sunday and early on Tuesday, though they appear to be part of a growing strategy to bring home the consequences of Vladimir Putin’s war to Russia’s civilian population.

The Ukrainian presidential adviser Mykhailo Podolyak suggested in a tweet on Tuesday that the Russian capital, whose residents have largely been able to ignore the devastation being meted out on a daily basis in Ukraine, was experiencing payback.

“Moscow is rapidly getting used to full-fledged war, which, in turn, will soon finally move to the territory of the ‘authors of the war’ to collect all their debts. Everything that will happen in Russia is an objective historical process.

“More unidentified drones, more collapse, more civil conflicts, more war …” he wrote .

Russia’s economy ministry said its employees were working remotely after the latest attack. Moscow’s Vnukovo airport was also temporarily shut and flights redirected.

The Moscow City district towers, often unoccupied at night, are located further from the Kremlin than other highly defended government targets such as the ministry of defence, where Russia had stationed a Pantsir S-1 air defence system on the roof last year, and present a large, tall target.

In a video address on Sunday, the Ukrainian president, Volodymr Zelenskiy, made the same point as Podolyak as he said the war was coming home to Russia after three drones were shot down over Moscow.

“Gradually, the war is returning to the territory of Russia – to its symbolic centres and military bases. This is an inevitable, natural and absolutely fair process,” Zelenskiy said.

The attacks on Tuesday marked at least the fifth time that unmanned aerial vehicles have reached the Russian capital since May, when two drones came down over the Kremlin. Moscow and its surrounding area are more than 500km from the Ukrainian border and the conflict there.

While the damage so far has been relatively minor, the attacks appear designed to show up Moscow’s vulnerability to drone warfare. Ukrainian bloggers on Tuesday ironically repeated claims made in April by the commander of Russia’s air defences, Lieut Gen Andrey Demin.

“There is hardly a better sky shield anywhere in the world than Moscow,” Demin assured a Russian newspaper.

The Russian defence ministry said on Tuesday that it had also foiled a Ukrainian drone attack targeting patrol boats in the Black Sea.

The attack on Moscow came as Russia launched its own drone strike, on Kharkiv, Ukraine’s second-largest city, injuring one person. Five Iranian-made Shahed drones were deployed, Ukrainian officials said.

Two floors of a college dormitory were destroyed and set on fire as Russia targeted “densely populated” areas of the north-eastern city, the mayor, Ihor Terekhov, said on Telegram on Tuesday, adding that three explosions had been heard in the city.

The chief of police in Kharkiv, Volodymyr Tymoshko, said there were two night-time strikes – one on the college and one on the city centre. One person was injured in the city centre.

It was unclear whether anyone was in the college building when it was struck, with local media initially saying it was empty and later reporting one person had been inside.
