AC Question

Hi team.
Ever since I rooted my phone all my apps keeps stop responding. I had to reset phone and start again with a blank phone. I tried the below to fix it-
Factory reset n number of time
Factory restore .
deleted catch partion data .did factory reset using power shortcut keys.
Unrooted as well. Still all apps crash.
I noticed my phone is trying to read/ write to some ghoust space. My phone is just 1GB rom model however catch memory shows xxxxx bits and total 2TB. Yes 2 terabyte total space. Plz help me understand this issue.so that i can fix it

Thanks.
