Is the battery backup time decrease by a huge margin? Plzz give little bit more details and also suggest whether should one go for an update or shouldn't do it now?

Same my phone's back panel has also come off. Btw how much it costs you to fix it?

But its not working

Yeah thats what i am saying mine too worked when i bought the tab in october but since 1 month its not working i can copy text across the galaxy devices using the samsung ecosystem but not with the screenshots. Should i take it to the service centre

Actually its a feature of galaxy ecosystem and even it worked seamlessly for me like copy screenshots and text across galaxy devices. But for sometimes the copying screenshot feature is not working don't know why? Want to rectify this problem
