So last night my phone decided to start running super slow w/ lag. It takes forever for texts to send or come in. My battery stays hot now. I use apps like du speed booster, turbo booster, Icleaner, and clean master to help with cache, junk files, and battery temperature. Today, my phone went from a full charge to dead in 3 hours. It usually lasts all day. I can't seem to figure out the problem. I thought maybe if I were to update my apps in the play store it may fix my issue magically. I don't have data or WiFi so I used my one opportunity at a friend's house with WiFi to attempt updating apps tonight but was unsuccessful. The app would download to 100% but never would install, it just stalls at 100%. If anybody can help me with any of These issues please help me out. Thanks for your time.
