I agree with SamSV. When I purchased the note 10.1 when they were first released, samsung promised to keep the tablet up to date for at least 5 years. One update after the initial release and that never happened (just a lot of broken promises.)
beyond this: I have since purchased the S5 (mistake) which after just over a month of use, all the pictures and videos (no other files) disappeared. This is obviously a software issue, so I TRIED to contact samsung "support" both through phone and e-mail. On the phone "support" transferred me to the "tech support" who never answered (I sat on hold for 2 hours before I gave up.) Their e-mail "support" only sends a generic response, with no way to respond (contact information is fake, mailer-daemon.)
[bottom line] Unless you need the pen, don't waste your money on samsung mobile products. No updates, no support, means no more samsung for me.
sincerely,
ex-samsung fanboy
