buey tahan. when turning it on from when the screen is off to check phone, it keeps lagging now. happens a few times in a day but still on and off. not all the time. the fingerprint scanning is not responsive and phone just hangs. -_- if it keeps happening i will reset the phone.
i am not using battery saving mode btw.
I encountered the same thing too, after a week, I did a factory reset and I don't remember seeing that happen as much anymore. And since the reset, power saving mode is on all the times. Seems to helps a little for me.
I've also figured out what was killing my battery life even on power saving, the wifi at work. Maybe poor signal or too congested. Now with wifi off, and 4g all the way, after 12hrs of use and 2hr 40min SOT, I'm still at 53%, which to me is pretty good already.
I've been using since launch and have only seen it auto reboot just once last week. Hopefully Sammy will resolve all these soon.
