A70 screen will not dim/USB connection.

Hey,

 

I've noticed a problem with my A70 regarding trying to dim the screen when locking manually or expecting it to lock after screen timeout.

 

Basically, my phone won't sleep, at least not whilst charging. I spent a good while playing around with settings on my phone, such as timeout and lock screen settings. I also powered off the device but no luck.

 

After trying to figure out the problem further I discovered that the notification tray is being constantly updated every few seconds swapping between "Android system USB connector connected" and "Android system USB connector disconnected". So presumably this is what is keeping the phone awake as it thinks it is being constantly connected and disconnected from source USB source. I cleaned out the USB port but it was pretty clean to begin with. I'm not getting any notifications regarding any moisture detection.

 

The A70 charges just fine (though sometimes there is a slight delay to it recognising being plugged in) and it seems that the USB tethering interface is working well as I can use the remote debugging feature in Google Chrome (for web development purposes) just fine. As far as I can tell, there are no actual issues with the USB port - it functions as I would expect.

 

The A70 was last updated on the 14th August to "Security Patch level: 1 July 2019" and looking over the log of updates I see that "The charger/USB port's moisture detection algorithm has been improved" - so someone somewhere has been looking at this feature and I doubt it coincidence that my device has just developed a fault, given that I've not had it anywhere near moisture or excessive dirt.. and the port still actually works!

 

I've also tried Safe Mode but the issue persists. Also, if I power the device off, then plug it into the wall, power it on, the notification issue stops... until I unplug it/switch off the wall socket - then it comes back again.

 

Anyone else having similar problems?

I am having the same problem and also only 4 months old.  Samsung are saying they wont repair under warrenty because i have a scratch on the front of my phone therefore warrenty invalid.  To say i am annoyed is an understatement.  Will be cheaper to buy a new phone for the price they want to charge (the privce i was quoted was the minimum it would be), needless to say iwill not be buying another samsung

While the phone is on, press volume down and power button for 10seconds till the phone restarts. I think this works.

 

Update: I change sides of the cable (because my A70 is in to type-c in two sides) the charger side put on phone and the phone side put on charger and I do the restart with buttons when I unplug from charging 2 or 3 times till the notification do not show anymore.

 

ps. Sorry for my english, hope you understand.
