The Samsung Galaxy Note 4 is a cellular smartphone that was released in October 2014. The Galaxy Note 4 Model Number is SM-N910, SM-N910A, SM-N910T, SM-N910V, or SM-N910R4 for American variants.
My Note 4 powers up but stops at the T-mobile screen. I have tried restarting it several times but it always locks here. To end the lock up the battery must be removed.
