I have a problem with my tab. With the new version of Play Store, My tablet PC keeps restarting. So, I restored Google Play to the Factory Default. Soon after, it updated itself, causing the device to restart repeatedly when in standby. I am running 4.1.1 on my Karbonn ST10. I, at the time of posting the question, do not have any intention to root the tab.
Thanks, Oxylibrium.
