Try pressing hard on the back of the phone about half inch up or by the buttons before opening the phone as it can be loose connector and just by pressing it works, sound unbelievable but works !
i did some research and i found out if your a70 falls very hard part inside the phone may get lose , the flex cable especially which is located by the samsung logo its responsible for chagrining the battery, all you have to do is get someone to open it and connect back the connector properly i had the same experience when my phone fell.
@@mauihimself1007 be carefull dude it's very fleeting worked for me for a few weeks then I'd need to do it all the time, then it just didn't work anymore. Got a pixel now much better build quality and the same rough price as the a70
