[G2 Q&A, Help & Troubleshooting] revan17:
I've been having sporadic hard reboots ever since I got the phone. It happens sporadically; perhaps once in 2 days. I really can't pin point what causes it. I'm pretty sure I had one while the phone was completely stock, not rooted, not loki-fied. The last one happened just now; I opened YouTube and the system rebooted.

I'm on stock 4.2.2 10a, rooted, TWRP installed. Of tweaks, only greenify and Xposed G2 settings. Everything else is stock.

Can anyone help me find out the cause for this?
