Please help, performance and pin problems.

[porshacat]

My Gs3 has become slow and has problems with freezing. Restarting it used to help this somewhat. Now however I have a problem. When I switch it off, then back on, or restart , it will jot accept my pin number. I am using the one I always had, I have not changed it, I would not know how.
I would indeed like to know how I can have a look at my pin, just to make sure it is unchanged and correct ?
Anyhow, I enter my usual pin, three times, then find myself locked out !!! I have acquired my PUK number, I have to enter this, a number of times to get back into my phone ??
It's all very trying !
Could some kind soul please help me ?
:'(

I don't think there's a way to simply look at what the PIN number is. You may have to go through Android Device Manager with the gmail address you're signed into and reset it that way.

Its just a ghost data issue, no need to reset. Search in search bar above for ghost data problem.
