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.
After open and repaired the camera on Samsung Note 4 (N910) , I have problems to use back button only by fingers. The button is working perfectly using the pen. Any idea ?
