I bought 4 G300's for my teenage kids. One of them has an erratic working touch screen. I have installed "MultiTouch Visualizer 2", and this also shows the problem: at certain (big) parts of the screen, it just drops contact, as if my finger wasn't on the screen, and sometimes the cursor starts jumping all over the place. I have tried a new ROM (ICS), but this did not solve the problem.
Does anybody have a tip on what i could try to solve? I have already entered the service mode, under the Project menu (Dial *#*#2846579#*#* , select Project Menu) under which is something with a touch firmware, but i have no new touch firmware i can try.
