Black screen, white "x", and Galaxy S6 won't charge

AC Question

Hello all,

My S6 is about 1.5 years old. Since about 3 days ago (Friday, 4/28/17), I've started having this problem.

The phone randomly makes a beep noise, and then turns black. A white "x" appears on the bottom of the screen. Then, the black screen disappears and it displays whatever I was looking at prior to the black screen's appearance.

I've noticed that every time the black screen with the white "x" appears and disappears, my phone can't charge afterwards. I've tested two cables, plugged the phone directly into a wall socket, and tried two different adapters. I've made sure both the cables and both the adapters work by testing them with another phone.

Forums show that other people had similar problems in the past. However, their black screen and white "x" actually stays on the screen without disappearing. And, they don't report any problems with charging. The black screen and white "x" seems to be associated with some Samsung Gear VR app though ...

Using the reboot trick (power button + volume down), I am *sometimes* able to get the phone to charge after the reboot. Other times it'll reboot but still be unable to charge.

Alternatively, I tried shutting the phone down normally (hold power button, select red "power off" button). Same thing happens; sometimes it'll work when I start up the phone again, sometimes it won't.

I've also plugged the phone into a portable charger and the charger would light up, as it normally would when it's charging a phone. Despite the charger lighting up, my phone wouldn't actually be charging.

I've already tried factory reset. I've also tried wiping the cache from recovery mode. No good; problem still persists.

I'm out of ideas.

Any help is appreciated.

Andy here. After a few more restarts, even restarts don't fix the problem. Hardware issue? Could it possible be the pins on the charging port?

Same thing is happening to me. Driving me absolutely mad. I just factory reset my phone, put all the apps back on, and it started again. I know it is app based, but I don't know which app is causing it.
 
I am having the same issue I saw this issue in February and it went away. It now is back with a vengeance. My car charger (https://www.amazon.com/Charger-JETe...ag=hawk-future-20&ascsubtag=UUacUvbUpU5835661) is the only thing that I can consistently charge my phone. I just bought a wireless charger. If this was a hard ware issue I would not be able to use my car charger every time. On some cables I am get the dreaded "this cable is not compatible. I will have a wireless charger tomorrow. I hope that fixes things. This issue is driving me insane.
 
Mine is doing the same also, won't charge either, a x comes on the battery saying use default charger the phone came with. I went through newly updated apps and uninstalled Samsung push service updates and so far (past 10-20 mins) it has stopped popping up that black screen with the white x and is charging again. Probably samsung's plot to get us to buy their new phone. Not due for an upgrade for another few months >:(
