App crashes before unity logo loads

First, Merry Christmas, hohoho

Now down to business. I have a little needle in my boots that's been annoying me for a few days. I noticed that my app crashes on my phone, after about 2-3 days.

What happens is that everything works fine. I can restart the app, restart my phone and everything works OK. If 2-3 days passses and I try to start the app, I get this message before the Unity logo even loads "Unfortunately, <AppName> has stopped."

I'm using Unity 5.4.1.f and I'm deploying to Android...

Do I need to try ADB and logcat to see if I can get any information? Or have you guys got any idea from the above what it could be? At first I thought I should probably cleanup to ensure no leaks are causing the error, but it still crashes even if I restart the phone...

 

This is what adb logcat returned:

A lot of entries saying unused DT entry like this:

I think it's due to the install location. I've tried setting it to internal now and will report back in a few days if that fixed it.

 

Yup. This fixed it for sure.
