Ramdom phantom button presses
I have a UK Nexus 5 running 4.4.2 rooted and with twrp 2.6.4 installed.
Everything was fine until a few days ago when I installed Angry Birds Go! and Android Device Manager, since then as i try to use the touchscreen phantom presses occur i.e. button presses at completely the wrong point of the screen i'm pressing.
And it has made the phone unusable. I have no idea how this occurred as I doubt those apps i've installed caused it.
Even more worrying I booted into TWRP to wipe cache and phantom presses STILL occured.
Also Wiping the cache didn't help.
Could I have some deep rooted malware that the Avast! android AV app can't find.
Do I /can I do something to recalibrate the touchscreen?
Worried about my new phone....
