The Samsung Galaxy Tab S 10.5 is the best tab I’ve ever used, I even recommend this tablet over the Apple iPads. It has about double the hardware of most iPads. Samsung will take some time to release Android 5.1.1 Lollipop for this tablet, but you can update it to Android 5.1.1 Lollipop right away using an unofficial build of CM 12.1 custom ROM. This guide will give you all the info about installing this ROM on your phone.

You need a PC with internet connection so you can download the ROM zip and G apps zip file for your phone. Get your tablet ready for this update process by rooting and installing any custom recovery to it. Make sure that the custom recovery installed by you on your tablet is latest so it can support Android Lollipop based custom ROMs. You also need a USB cable to connect your phone to your PC.
