So i had a funny moment, but all good thank god!

Basically, i'm on Android 6.x.x and while in flight, about only 150 Meters away from my Position and ~100Meters in height, the App told me "Critically Low Battery!" I had 60 % Left and immediately checked Voltages, all Cells about 3.80V.

After that, the App crashed, but i restarted it 1st try no problems. My question: Did anyone see this happen? My guess is the App just said that randomly, because it was going to crash any second.

And also my 2nd problem is, i hate that HERE Maps don't move with the Aircraft position, rather you have to open the whole map and look which direction you are facing :S

So if DJI can fix the App crashes with Android (and possibly iOS) + fix Here Maps to show AC Position, like Google maps did, it will be golden! Never had any other problems.

May I know the model number and mobile system of your android phone?
Have you flew it with other mobile device and check whether you have the same case?
Export the crash log for us, you could check it here: /sdcard/DJI/dji.pilot/LOG/CRASH, you will see the crash file. Then upload it to dropbox and provide us the link.
BTW, please sync your flight records through APP and let us know your APP account e-mail.

Hi, thanks for getting back to me.

I havent flown with another device yet, but the DJI Go App (Not Go v4) worked always fine.

And btw check this out:
http://www.kopterforum.de/topic/ ... ld%C3%BCbertragung/

It's a german forum, but basically he's saying he had a frozen Video Transmission and then after that a Black screen where nothing was functioning except RTH.

He was using Android 6.0.1 just like me

Hi, thanks for getting back to me.

I've transferred the crash log to our engineers for further evaluation.
It's appreciated if you can try another mobile device with DJI GO 4 and check whether it will perform fine.
BTW, your APP account e-mail is the same one you used for forum, right?

[Update]

It happens on all Devices with Android (3 Tested) whether it's Android 6.x.x or 7.x on both. It crashes randomly, on random things, even when not touching the Smartphone at all. It's pretty dangerous, if you fly say 2 Kilometers and your app crashes randomly, you could lose your Phantom.

Google Play Store also pretty much confirms this, look at the Reviews almost every single review says it crashes Randomly. We need a fix ASAP guys.

iOS is fine. (iphone 6s, iPad Air 2)
