Why does my samsung tablet gt-p5220 switch off by it self?

Try a Hard Reset which clears everything off it and installs Android new. There are no Android download links.

In Settings-->Display, what timeout setting did you set? Check/change this as necessary.

Sometimes hold your finger on email and menu comes up.

Check this link for a simple fix for the problem that you are experiencing.

HI i had the same problem with my Galaxy S2. I have bad news for you its IC is gone, I gave it to samsung warranty they fix it for me.

The only way to remove this if you don't have it re-registered to your own google account yet is to do a hard reset switch off the tablet in the normal way then switch it back on by holding down the power button and the volume up at the same time and choose factory reset this will unfortunately lose all your data but I'm guessing it wasn't your data anyway lol

Some tablets will have a physical rotate lock switch. There is also a setting that locks the rotation. Settings > Display. Auto Screen Rotate.

Retrevo has a 3+ MB manual for the GT-P7510/MA32ARB here: http://www.retrevo.com/support/Samsung-Galaxy-Tab-10.1-32GB-Tablets-manual/id/23956bh051/t/2/ . You will need to enter a code to access the manual; it's a PDF. This is a generic Galaxy tab manual.

Samsung has several models in the GT-P7510; however, their support site doesn't match the exact model number. One of these manuals may have the details you need for your tablet. (I checked just the Wi-Fi tablet section; if you have a specific wireless provider, check those manuals for a similar model.)

I hope this helps.

If your Samsung GT-P1000 Galaxy TAB is frozen and unresponsive, press and hold [POWER ] for 8-10 seconds. The device will reboot automatically.
If this does not solve the problem, perform a factory data reset. In Menu
mode, select Settings ? Privacy ? Factory data reset ? Reset phone ? Erase everything
