I've been using it for 7 months with no problem , and on this month the phone starts having an issue with touchscreen and back button. I'm using it and all of a sudden : The "Back" Button starts being Automatically pressed for many times , as if I was pressing it ( but i'm not) and then after that the touch screen with Back , settings , home buttons is left Non responsive , i touch everywhere and it won't work. I have to press the power button to switch off and on the display for it to work again , but right away after i do this the issue restarts. I have tried complete nandroid restore with CWM from the early time i got the phone , didn't work. Do you guys know what could be the issue ? I'm attaching a Bug report of the developers android option just in case it helps

Honor 6 Touch problem

Dear Friends,
I bought Honor 6 model H60-L02 two days ago ( From China to Egypt ), but I have annoying problem with the touch
The phone come with screen protector, and touch was very bad with it , when I press and hold (for example in shooting games ) it seem that I left the press ( but actually I still press ), and some time it seem as i press on nearest button ( but actually I don't)
I removed the screen protector, and then the problem was partially solved
Also some time when I use Facebook app and drop up or down it's hanging ( select any clickable link, go down or up with speed ) and this is the annoying problem
I notes that when i lock the phone and unlock it again it works well and then return again
Hope if you can support me to solve this problem
thanks in advance
