Default Replaced cracked Digitizer

I dropped my GT-P7510 and the screen shattered but didn't call out. I was able to use the tablet but was worried about cutting my fingers as I swipped. I bought replacement digitizer on Amazon for $15 and with the help of a YouTube video was able to remove the old screen and install the new one. It took me no more than 20 minutes, all I needed was a hair dryer and a few butter knives.

"This seemed too easy" was my thoughts as I was powering the tablet. Everything started up fine, was working perfectly UNTIL I noticed a few "dead spots" on the new touchscreen. One of which is right over the install button in the Play Store.

It's not the end of the world as this tablet is quite old and I really only use this to play Appeak Poker and the only new apps I install are the sponsored apps in Appeak that give me free chis just for running them.

Has anyone else experienced this problem after replacing their digitizer and if so, is there a fix?

Thanks
