I’ve got two current issues with my Samsung Galaxy S9 purchased from the e shop.
the phone has started giving off a weird notification sound when performing normal functions like turning on the display - here is a link to a video. If I set the phone to vibrate it stops the noise from occurring. It use to occur intermittently, but now it is a constant issue.
the phone sometimes gets to around 30% battery and then seems to overheat, and then turn off.
Would be great to hear any advice that you might have.
