Over the past couple week my phone has been running very slow. Ill hit the home button and it takes forever to get to my lock screen, or when im opening up an app the phone temporarily freezes. Restarting it helps but only for about a day. I haven't installed and sketchy apps, I have done a factory reset, I have cleared the cache, i have disabled all bloatware, and i have ran lookout security. The phone is not over heating it often does this when the phone is at standby temp. So any other suggestions on how i may fix this? Thanks
