The device is too large. The pin functions are not fully developed. OCR does not work reliably, even when captured from PDFs texts are letters replaced by special characters. Too many apps installed that do not also can be uninstalled. The Home button is too far out of the housing so that it is always pressed in the shell and thus the device remains switched on continuously. So the cover purchase, make sure that at the point the shell is recessed slightly.
Apps like S Note are absolutely unnecessary because they have a very poor usability and barely useful feature. The original alarm will stop after a few seconds. This function can not be changed also.
