On my Android phone the DJI Go 4 app crashes right after the version check if I open it a second time after installation. Opening the app the first time after installation it works fine. 4.1.3 worked fine, 4.1.4 and 4.1.5 crashes.

Display
- Resolution        1080 x 1920 pixels (~424 ppi pixel density)
PLATFORM
- OS                        Android 7.1.1 (Nougat)

- GPU                        Adreno 506
MEMORY
- Card slot                microSD, up to 256 GB (uses SIM 2 slot)
- Internal                32 GB, 3 GB RAM

What mobile device are you using? Could you please provide us with a video about your case that changing device language fixes the crash issue? Thank you in advance.  

Potentiale on to something, I imagine there are a few android devices at the DJI HQ, mind trying to recreate this bug?

I edited the original post after trying to reproduce the behaviour. It does not have to do anything with localization. Checked with English US and German settings. Crashes on both.

As I checked your thread again, found that the device you are using was not on our support list. It might be a compatible problem. But that doesn't mean it will not work with DJI GO 4 all the time. You can try to reinstall the app by scanning the QR code of our official product website or wait for an app updating. And we also recommend using the device on our support list. Thanks for your kind understanding.
