Hello guys. I was planning to get a Nexus 7 1st gen when I won a Galaxy Tab 3 7.0 on a raffle. It works for me eventhough it`s not as fast as the Nexus. The only thing I am concerned is that it only got to Android 4.1.2 and I was excepting to use the users login function, which is only available after Android 4.2. Does somebody knows if there is any custom ROM available out there that allows me to install this version or a better one for my tabler?
