my galaxy s4 gti9505 got water damaged
i opened it and cleaned it the propper way
now then first phone would not charge and after more drying and cleaning finally got to work.
the problems are as listed below
-touch screen sometimes starts responding on its own without me even touching it but after pressing power button and turning screen back on starts to work again
-will not connect to computer did before but now has stopped keeps saying connected to dock but charges
-touch screen above the home button and menu button and back button about 1 cm of the screen does not record my touch for eg. if i type in a keyboard holding phone vertically i cannot use the space or symbol or even keyboard setting (however when phone starts responding itself them buttons start working by themselves but will not allow me to use them sometimes i can use space).
ok now what i have done so far is as follows
- was rooted so my knox counter is 0x1
-warranty has been voided because of water damage and knox counter and i also spoke to samsung and they said we will charge you for fixing it but not sure what the problem is
-its on android 4.4.2 stock now but no propper bootlader as it was on chainfires root
-i cleared cache and full factory reset several times
i changed my charging port unit but made it worse as i could not lock screen using power button kept waking up strait away so i changed back to my first charging port flex cable and that issue has been sorted.
im using the phone everyday and touchscreen works fine apart from that little problem so im thinking the digitizer is ok
i think it is the function button or sensor that is causing this problem i am having
need your help guys
