At the moment I am running the latest version of LinageOS. Installing it was no problem at all, but sometimes when my battery life is 50-40% and less opening some apps will crash for no reason at all. The OS I was running before was Android 6.0 (Before I went to Lineage I tried to root my phone and almost screwed it up so I had to go back to 6.0) and the same thing was happening. As far as I can remember before I tried unlocking bootloader and doing other such things my device wouldn't crash running Android 7.0 but all of a sudden my phone would crash and every crash it would take away quite a bit of battery life which is annoying. So far I haven't found any soloution so I thought I'd try my luck here. Thanks!
