Erratic touch screen after digitizer + LCD replacement
I replaced the digitizer and LCD on my 1st generation Nexus 7 with an apparently identical Hydis LCD/digitizer assembly. Now I am experiencing erratic behavior of the touch screen, some dead spots, scrolling registering as touch, etc.
Could this be a grounding issue that happens now because I did not properly put the unit back together? If so, which areas should I focuse on / cover with electrical tape to try and get rid of the issue?
Could this also be a software issue if the lcd/digitizer model is not exactly the same? The numbers below the "Hydis" markings are the same as on the original unit, but the numbers below the code bars are different. If so, is there a solution? Drivers? Calibration?
Thanks in advance for any insight.
