Magenta has rolled out firmware version P607TUVUBOI2 for the Galaxy Note 10.1 2014 today whereas version T337TUVU1COH5 is now available over-the-air for the Galaxy Tab 4. Both updates bring all the bells and whistles that we have come to expect from Android 5.0 Lollipop and also bring a fix for the Stagefright security vulnerability. It can't be said for sure right now when Android 5.1 might be released for these tablets, and with Android 6.0 Marshmallow just around the corner, it might take a long time before the very latest version of Android arrives for these tablets on T-Mobile.
Update: One of our readers has pointed out that the update that T-Mobile has sent out for the Galaxy Note 10.1 2014 is actually Android 5.1.1 and not 5.0.2 as mentioned on the carrier's own website, screenshots provided show that it is indeed Android 5.1.1 with features like multi-user accounts.
Thanks cowbelt!
