I have an 8 month old Samsung Galaxy Grand Prime smartphone. It has worked fine until I dropped it a few nights ago. Now all of a sudden the touchscreen doesn’t seem to be working correctly… It will lag or stop responding or respond erratically. I tried several fixes including taking the battery out, restarting, doing a TPS grid check,putting it in safe mode and uninstalling and reinstalling apps, etc. It is still not working normally. I need to know what to do. I do not have a service contract or insurance, bought the phone outright and use straight talk. Thanks.

Thank you. I bought it at Walmart so taking it there probably won’t work lol. I found a repair place though, I’m going to take it in tomorrow.
