Samsung Galaxy S3 Touchscreen Unresponsive?

[Ethan Kyne]

Two years ago or so, I dropped my S3 on a sliding glass door railing and broke the LCD beneath the actual glass display on the top. The display itself wasn't cracked, you could only see the crack beneath the glass on the LCD itself. The phone would not turn on and only the lights would appear, (vibration, sound, and LED lights all worked).

So after such a long wait, I attempted to repair the phone myself after much researching and observing from repair videos. I purchased a LCD Display + Touch Screen Digitizer Window unit that was compatible with my MetroPCS model, SCH-R530M.

I have successfully replaced the LCD and reattached the cables myself, following techguyz708's guide on YouTube: Samsung s3 screen replacement Tutorial LCD and Digitizer. I had no cracking of the new unit which I ordered, no cracks or scratches. Connected everything together and the screen turns on perfectly, no discoloration. It boots to my previous pattern-lock screen; but unfortunately my touchscreen is unresponsive and doesn't work so I cannot get through. I have read that resetting the phone to factory settings may work, but have heard many unsuccessful reports. (I would prefer not to have to hard-reset my phone because I have many cherished photos that I would like to recover somehow but have no idea if I properly backed up my files.)


Any suggestions or ideas?

You forgot to connect a connector, pinched a wire, the digitizer is defective ... there are many possibilities.

That's why I always say that it's cheaper to pay a shop to repair it. Now find a shop that will work on it without resetting it and pay them for the work.

Can the digitizer be defective even if it turns the screen on? The seller asked me to return the digitizer and that they would give me a refund. I have already taken the complete unit out and it still powers on once it is connected through the main cable, just the touchscreen is not working. So this could be a result of a defective digitizer even though the screen powers up? Thanks by the way
