[Q] "S820 MTK6582 Quad Core" Touch screen and 'Back' button problem

Hello guys i'm having an issue with my chinese phone (Exact phone is : Dealextreme's S820 MTK6582 Quad-Core Android 4.2.2 WCDMA Bar Phone w/ 4.7" QHD, 4GB ROM, Wi-Fi, GPS - Black ). 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

[HELP] Touchscreen Problems in my Galaxy S6

Perhaps the problem I have to be a little "weird" to understand, the fact is that it works, but I ask the help of the community, if possible ...
I have a Galaxy S6 Flat (SM-G920I model), and there is a problem with my touch. When I click on the screen, it takes about 3 seconds to respond. But if I disable the "automatic lighting", the touch screen works (you can see on the display image that the button has been pressed), but there is no answer. I made this test an official ROM from Samsung ...
On the other hand, I did the same test patterns above, now a custom ROM (NobleRom_edge + _20151218 deodexed), thanks to XDA for the ROM. After the same process (3 seconds) remain with the problem, but when I disable automatic lighting ..... VOILA !!! Works normally touch, but the "scroll" only works if u move your finger on the touch down very slowly.
Also I made a test call on the device, but the screen is blinking during the course of almost dark call, really weird right? Oh, and after 15 seconds of inactivity, my device does not turn off the screen just stays on.
Finally, given these problems, I do not know whether the problem may in fact be the touch, or the light / proximity sensor, since disabling the option, touch works ...
...regardless of the aid (which I believe is a major challenge), I'm grateful, because I do not want rid of that S6 is an excellent player and I love it !! Sorry for my bad english
Thanks and regards...
