My S5 is overheating when it's charging .... and getting quite very hot when I'm outside with 30°c or so the phone starts to heat up very quickly ... please help me on this

Is there any possibility to get official Always on display service on my S5 without downloading any third party apps from play store.

My NFC tap to send is not working ... whenever I tap on an another NFC device it's not working .. in this case my laptop and another NFC enabled​ phone .. I select the pic that I want to share via NFC .. I switch it on ... Android beam and Sbeam on ....

please remove the "power saving on". .. notification from the notification panel.. as it is taking a lot of space in the notification panel. just make an icon near the battery icon at the top.

will the S5 get Samsung pay ... as it has that payment capabilities ...
