I received a Samsung Galaxy Tab 3 (SM-T310) as a retirement gift last week and it had android jelly bean installed. the tab comes with GPS and on the weekend it automatically upgraded to KitKat 4.4.2 as it was set to automatic update. I then lost the GPS from the drop down menu. so GPS has disappeared from the tab. I contacted Samsung help line here in the UK and they could not give me a reason or a fix and suggested I reverse the update back to JJ. any idea why this happened and is there a fix?
