As of a few weeks ago I noticed my phone would randomly restart, I didn't think much of it until one day it shut off, restarted, and then it was locked and would not unlock no matter how long I held the side button down for, plugging it into the charger did nothing. I ended up having to let the phone just die and recharge it once it had died. I could deal with all of that, but today I noticed after it had some sluggish responses to me wanting to unlock the screen (it would stay locked and not respond to button presses until i waited around 2 or 3 minutes after hitting the button initially) I tried to use several applications, the appstore, snapchat, youtube, and i got little to no activity from any of them. Neverending loading from just about all, or no activity whatsoever from the appstore, yet the net browser and facebook/ etc worked just fine. And to top it all off, I noticed my battery draining at an alarming rate, maybe 10% every 30 minutes even with nearly no applications running or open.
If anyone has any idea what is going on, it would be very appreciated, I'm about to go crazy here.
