My dad has a Samsung Galaxy Tab 2 7 (I think p3110) and he has had some lag issues. He is running stock Sammy 4.2.2. I suggested he factory reset his tablet. We did this by holding power and volume up. Wiped data /factory reset and then cache partition (it rebooted automatically). When up and running he logged into Google account but then when he opened play store it said it couldn't connect. The Internet browser would not connect. But he could send and receive emails through sock email app (!). We tried factory reset through settings app and have tried removing and readding Google account and also clearing Google services and play store caches. Nothing seems to work. Anyone any ideas please?
