I bought the phone a month ago and it's perfectly fast and smooth,
I used it a lot but one day, I shut it down to give it a rest for almost 7 hours
then "Optimizing Apps" start for about 7-10mins, then I noticed that the unit is heating unusually than before.
The Unit started to have some lag issues and I noticed that the Heat is on the upper part only.
I read some solutions like installing Phone cooling apps but is there more other options?
