I had used samsung galaxy tab S3 having android version 7.0 Nougat. It blatant in features.
some tips I like to share witg you guys-
1.Widgets: - just you have to long press the home screen to bring the option to add widgets.
2.Proper handling: - Keep a firm hold on your tablet with both hand while using as size is slightly bigger abd may slip from your hand.
3.Keyboard handwriting: - Instead of typing letter with key board you can your finger to write text and then it will convert it to typed text.
- Surfing: - websurfing can be done but my call experince in not too gud so not for a call purpose.
5.Factory reset protection: - If you ever want to sell your device make sure to remove your google account.It can be done by selecting factory reset from settings menu.
6.wifi tip: - Close wifi when not in use as this is unnecessary waste of battery power.
8.lastly, Enable screen off memo : - This feature ebables you to write some character or pattern on screen to open screen.
