That's terrifying! I stopped tinkering with ROMs because the one I was on would crash a call 5-10 minutes in. Calls are usually short, so it didn't bug me until it crashed twice during a long call with my parents. I realized my phone had become really bad at being a phone.

I switched to iOS shortly after because when using stock all my Google apps would constantly throw warnings that I had denied location services. Even apps like Gmail would prompt me with every new send.
