G’day all 🙂
Recently my partner broke her digitiser glass on her HTC Sensation.
I ordered a replacement digitiser from eBay, and fitted it.
It worked well for a couple of days, then started going mental.
To diagnose the fault, I downloaded “Piano For You” https://market.android.com/details?id=com.pash.piano&hl=en – since it makes it really easy to see and hear what’s going wrong. In my case C# was also triggering Bb and Ab.
It turned out in my haste to reassemble (stephanie) the phone, I didn’t really do much of a job with the adhesive; which allowed hand cream, chocolate, or god knows what to sneak into the side of the phone between the phone and the digitiser, creating a ‘conductive short’ if you like down the right side of the phone.
Fortunately, this tardiness meant it was easy enough to pry the digitiser away from the phone, as seen below:
This time I ran adhesive right around the edge, resting it diagonally along the ridge of the phone’s shell so that the LCD would force it both down and outwards.
So far, since then it’s been behaving 🙂
This might not work for other people, but it worked for me.
