My FP2 crashes regularly. The most common reason for a crash/restart is me using the Swipe keyboard in WhatsApp. This happens 2 to 3 times a day (I estimate it occurs in about 10% of the messages I write). The screen just freezes while swiping and after 10 seconds or so the phone restarts. It is very annoying because quite often longer messages I put in are lost.
Moreover, from time to time I take the phone and it asks for the SIM code thereby telling me that it had crashed/restarted at some point. This means I can be “off the grid” for hours without me noticing it.
Is there a way to find out what causes this nasty behaviour on an almost brand-new phone?
