unsupported apps that I use to get

Hi, i have the original samsung galaxy tab. My mom gave it to me when my other tablet broke, and she factory reset before giving to me.

Now the tablet use to have angry birds, candy crush etc. But now it wont let me download and says the apps are not supported by this device. I also have other apps that i have downloaded but they forclose before opening.

I have done a hard reset to see if it helped and it didnt change anything. Please help im about to through this at the wall.

Thank you,

Annoyed and pregnant
