Good day to all. For those who are experiencing the reloading of screen after playing games and browsing the net, I suspect that the phone runs out of memory whenever playing games that requires a lot of it. I  removed all the widgets I have in my homescreen (leaving only the clock with weather), restarted my phone, played a game and to my amazement the screen did not reloads.

I am not an expert. I may be wrong but this is based only on my own experience.
I hope this information can help.
