Hi Guys,

This isn't limited to Nexus devices, it appears to be Android in general, (although some devices seem to work better than others, most reports here seem to be Nexus/Pixel).

I just upgraded from Phantom 4 to a Phantom 4 Pro + (Plus).

DJI Go would regularly stop responding on my Pixel XL. I figured a fully integrated controller on the Pro+ would have to be the most stable solution on offer from DJI, however this morning it too stopped responding 4-5 times in a single session.

What's worse, is since it's a fully integrated controller, I have no option but to power cycle the controller, losing complete control of the aircraft, simply to relaunch the DJI Go app...!!!!

I use a Pixel XL and have not had any problems with the app at all. But I always turn wifi off before running the app. That is just a habit from the previous version of the DJI GO 4 app which used to come up with half a warning message about the wifi interfering.......  I have not seen this message on the latest version of the app as I started it a couple of times with wifi on but always actually fly with wifi off.

I was with some guys yesterday so there was 2 mavics nad 1 p4 and we all had Android phone/tablets and we all had issues with the app crashing.

My phone was is a Nexus 6P, one guy had a Samsung phone (not sure on exact model) and other guy had a Tosbiha tablet.

I have no idea why they can't get it to work fine on Nexus phones.

DJI Go crashed on my Pixel 2-3 times per flight. I always turned WiFi off as well, because it does cause interference, with it on the video would be dropping out after about 1KM, turning it off I could then fly out to 3.5-4KM (until the app crashed).

It's frustrating that the Pro Plus controller is nearly as unstable, yes it's better than the Pixel, but I still had maybe 4 crashes in just two batteries.

What makes the Pro Plus controller worse though, on the Pixel I could simply relaunch the app and be back within a few seconds, on the Pro Plus I have to completely power off the controller which takes a good 20-30 seconds and leaves me with zero control of the aircraft.

I am very familiar with Android, I could not find a way to relaunch the DJI Go app without completely powering off the controller.
edit: I discovered last night, on the Pro Plus, you can hold the power button on the tablet itself to perform a reboot of only the tablet. Still a lot slower than simply relaunching the app on the phone, since a full reboot takes 20 odd seconds.

DJI Go 4 working flawless with no issues or crash on my Note 4

Ive got a Motorola droid turbo 6 batteries and no crashes works flawlessly so far

testing 2123456

Well, worked fine at home during testing. Was pretty pleased with myself for buying the Shield after the trouble I had with previous Tablet.

Went out to the field and the Tablet crashed after 10 minutes on 2 Batteries. Screen just froze but luckily I still had control of the bird. Android 6.1.1 (or whatever the latest Marshmallow is) and DJI GO 4  4.03

It all Still works fine on wife's Iphone 6 though. Go figure

If I try with Litchi is that likely to be the same??

Disappointing to hear this, I will not use my Shield until I hear some good things again about it.  Thanks for the update.

DJIGo4 on a Samsung S7 Edge running Android ver 6. Zero crashes to date. Probably 6 or 7 hours worth of flying on DJIGo4. No crashes on DGIGo or Litchi previous to switching to DJIGo4 either though...

I'm having the same problem with my LG G3

I have some app stability problem with the supported Note 4

And it Just crashed again when i am in the middle of updating the Mavic Firmware tonight

Lucky that still recoverable

I have no problems with my Droid Turbo running DJI Go4 or Litchi .  I always cache the map at my flying location , stop all apps and clear from screen , place phone in Airplane mode then restart the phone before flying . Just a OCD thing , but I have had no issues since getting the Mavic at the 1st of January .

That is a serious lot of effort for a drone that is marketed such as the Mavic.  I think you have been extremely tolerant to do that every flight.

Don't want to sound smug, but I'm amazed more people don't run with the Sony Z3. It's on the approved list, it's cheap, it's got the best screen for outside use, it's big enough (5.2 inches) and for me at least, it's been rock solid with not one single problem.

Just a suggestion is possibly turning off some of the permissions for the app.  I don't understand why the app has certain permissions anyway, such as camera access.  I looked in my power settings and noticed the DJI app has used my phones camera for 2 seconds.  What exactly is it doing taking pictures without asking?  This is kind of disturbing to me.  I took a screenshot of the activity for future reference.

So if you limit the app to just flying the drone, maybe you will have better results?  Maybe some background activity is firing up and causing the instability.

Yeah my PIxel XL crashes the app constantly. Definitely when attempting to start the app in landscape mode crashes it repeatedly so if I lock the phone in portrait mode it at least gets in and flies for a bit but then it crashes randomly like once or twice when I attempted to switch to the map mode full screen.

I have the same issues with my LG G5.  It's super annoying.  Thankfully, it hasn't caused any major issues and the crashes are sporadic.  Sometimes, I get through a whole flight no app crashes.  Others, it'll crash 3-4 times.

First time for me yesterday. Samsung S6.  Pixels got all locked up and app was slow to respond while flying. I believe it was because of a email notification coming to the phone. On the next flight I closed all running apps, started DJI Go 4 and then turned on airplane mode. This seemed to fix the issue. I will test some more this week.

I have e a shield and switched to litchi.  No crashes very solid.  Will use going forward

After 30 odd flights ive found using the supplied usb(short) cable creates drama after drama. Switched to a standard usb 100% so far.

Hi all,

I'm getting constant crashes (every 1 or 2 minutes) with the DJI Go 4 app on Nexus 6P.

The crash logs are all the same error....

android.view.ViewRootImpl$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.

Except for one, which crashed with....

java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String android.content.Context.getPackageName()' on a null object reference

Anyone have any ideas?

Question to all you guys who have crashes:
Do you use some kind of task killer, or does your device not have enough RAM?

This makes no sense to most unfortunately,  if I use Go4 it crashes once or twice every flight, I swap the usb cable and it still crashes.   If I use Litchi I never have a single app crash. Trouble is using Litchi Voids my warranty.

I have same problem with Moto G Play.

I have the moto x play,  and it rocks,  yes be careful to ensure you have cleared all your background apps before using,   and i did have to do a small reversable mod to the tx right side grip though as the moto x play is deeper/thicker than most.  
How to make most phones most stable for the Go4 app:-
1) clear all background apps.
2) Then put phone into airplane mode
3) Then power off and back on the phone, but leave with screen off (normal while not using)
4) connect the USB cable
5) Power up transmitter controller
6) power up Mavic (wait a few seconds for self check)(DONT move the mavic through self check)
7) live up your phone ( button press and password or what ever brings yours to life)
8) Go4 app should autostart, ( wait a few seconds)
9) press the "Go Fly" button.
10) everthing should be good,  use small video cache sizes as possible (1 gb) or better still turn off cache,  also turn off sync photo with phone/device, ( you can always move some of the photos to your phone later)  remember this app appears to really tax a low cpu powered/low memory sized phone

With all the recent updates to the Go4 app, i doubt many of even these devices are powerful enough to keep up,    Go4 likes lots of very fast RAM and lots of very fast storage area,  and lots of headroom in the CPU,   it would appear the GO4 app spends a lot of time at a mid usage point, but then during doing its thing, it seems to want to do 2 or 3 things almost simultaniously,  and if it doesnt get them done when it wants to do it , it just throws its toys out of the pram,  and thats where users are seeing the lag and breakdown in picture quality and connection drop outs,  i believe the program gets choked,  and during that choke the program reports back to itself it hasnt heard from the mavic for a while, and then the issues compound,   i know thats not a techy way of explaining it,  and only my perception,  but its held true so far.

Very true ,  but !   if you want to be sure of a trouble free flight,   its such a crying shame that DJI dont build  the screen into the transmitter in a proper manner,  and that way lock up theProgram, CPU and memory to do just this job,  and rid themselves of this very nasty thorn,   trying to get all these different devices to work with a flying machine is just SO WRONG,   after all   Boeing doesnt ask its pilots to bring their ipad's along to fly a 747,   NO,  its very dedicated screens and programs to do the job with out fail !  by all means have a HDMI video out and USB video out,  so that the stream leaving the port can be put on a bigger screen or streamed to the net,   but for goodness sakes leave the control of the craft pure,  sorry thats my rant.

A great discussion on here and I would hope people agree that its for a reason.  If DJI didn't see posts like this they would think everything is perfect, so keep the comments flowing guys and lets get Android devices back on the "LOVE" list.  

As I've said before, no issues what so ever with crashing on Litchi, over 100 apps installed on my Oneplus 3, Android 7, 6gb of ram, 64gb of rom = (Fast as F***), no other apps crash, it's all down to bad coding (FULL STOP), all these workarounds  people keep posting up have no effect of Go4s crashing for me, it's a case of fly with Go4 and risk app crashes every flight and the possible crash of the drone because you lose your view from the drone until you relaunch the Go4 app but keep your Mavic warranty, or fly with Litchi, void your Mavic warranty, but have an app that never crashes.

I have lost the Go4 with crashing while using sport mode, very fast and dangerous when the app crashes and leaves you blind!

Not one crash with Go3 but that also voids your warranty too.

PATHETIC DJI, put your socks up and get a proper coding team.

My Pixel XL sometimes is fine, sometimes it crashes - I can't 'get it to crash'. It just does!
One thing I have at the back of my mind is that some Pixel users are saying "I have not had one single crash" - this leads me to believe that what could be causing the crashes are other apps doing stuff.
I am going to create a new user on my Pixel XL, and that new user will only be for when I fly and use DJI Go.
I will disable all other apps on this new user, and see if that makes any difference.

@Gusmtb I've just bought Litchi for my Nexus 5X and Mavic.

for the first time i flew without problems.

It was crashing couple of times to me today. Galaxy S7.

So it does work on a Galaxy S7? I was scared to try since it is not in the "supported devices".

I use a Galaxy S5 and once in a while it crashes. I have not been brave enough to really send my Mavic too far so it has been in sight and the app would start up quickly. Would be nice of DJI to get the app working well. I have not noticed any similarities in conditions when it does. In the 20 hours of flight time I have had maybe 5 app crashes.

Conditions that I am usually in are approximately 32 degrees Fahrenheit and elevations between 7,000 to 8,000 feet when it has crashed.   

I am using it on S7 edge. So far, the app never crashed for me. *touchwood*

AS I said,it's an OCD thing and it's resulted in 0 issues . I think DJI has spoiled people into simply wanting to grab a drone off the shelf and fly with no issues . No drone maker is to that point yet .  I'm 100% satisfied with what they have done with the Mavic because I have been building these things from scratch the last 10 years and have seen every issue that could possibly come up it seems ,lol .  I never thought I would buy an off the shelf drone but I bought my 1st one December 2015 which was a POS Yuneec Q500 4k for $1000 . That had a built in screen and had more issues that anything I had flown before . It almost turned me off from buying a off the shelf drone agin but I took the chance on the Mavic and it has been great . I like the idea that you don't need the phone screen at all to fly but it's available if you want it . Portability was DJI selling point .

They have no idea what type of apps and conflicts may be resulting from what people have installed on their phone . My daughter has had her phone lock up several times and had to uninstall a app that was the issue . If you want a dedicated screen I would buy a cheap used phone off Ebay and not put anything on it but the flying app . They work just fine without a sim card or cell service .

I agree, this go 4 app has frozen 2 of the only 3 flights. When talking to DJI support they ran through all the check lists and I did everything right. UNTIL I said "lucky for me I was able to fly back through the goggles because the goggles still gave me live feed" (the osd numbers had frozen in the goggles with the app crashing)

Then DJI support said "oh, you shouldn't use third party goggles as this might be the issue. You must only use the goggles DJI makes but are not available yet". Wait, what??? I thought that's why we put the hdmi accessory on it so we can use any goggles? I had 1,500,000 ft on my p3a with these headplays and never an issue. SUPER disappointed right now with the DJI go 4 app. I've uninstalled 3 apps (2 gaming) which I think are the culprits (i have my reasons). Waiting for good weather to test

I've seen a lot of mention of phones running Android 7 (Nougat) that are crashing.  Saw another thread on the NVidia Shield running with 0 crashes on Marshmallow (Android 6.0), but crashing on Nougat.  Rolling back to Android 6 solved the issue.

Can I ask those that are crashing what their OS revision is?

I want to ask a question as well:
For the ones crashing: is your phone rooted?

Maybe latest update of Android version of Go 4 (4.0.3) has improved stability on my Google Pixel. I have flown the new app version 2x 20min, and as far as I remember I had no crashes. Could have pure luck though. Have to fly it again to make final conclusions...
