Chosen Solution

My phone fell and the screen broke and became unusable. I removed the old LCD assembly, then plugged a new assembly. When I turned on the phone, everything was displayed perfectly on the new screen and all the buttons worked. However, nothing happened when I tried to tap or swipe. I already returned that LCD assembly because I thought it was defective, but I just received a new one from a different vendor and I see the same issue. I suspect there’s something I should be doing with my phone. Please help! Thank you.

If a screen replacement doesn’t solve it it would be more likely be an issue with the motherboard. Replacing the motherboard should fix the issue. The teardown guide below should help you out a bit with replacing the mobo. https://www.ebay.com/itm/OEM-CLARO-SAMSUhttps://www.youtube.com/watch?v=uIONMLkp
