@zelmax Pressing back button isn’t supposed to crash the app. Does the app crash entirely and not restart afterwards or does it simply restart after pressing the back button? If it is the latter, then it might be a low memory (RAM) issue. On which Android/iOS version does this issue occur? Is this behaviour persistent across different devices/emulators?
@LS0 Honestly, this is the first time I see this issue. Assuming that your device has a camera and a camera application (Android’s preinstalled Camera app works), this is unexpected. Can you replicate the issue on other devices?
