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?

It's the next day, woke up with no Android system USB connected/disconnected. Played clash royal for a good 30 minutes, then some games with high demand in power and performance like Call of duty for an hour. Battery is on 83%, heated up a bit after game play..but still no USB connected/disconnected in the notification bar. Phone can be dimmed/locked. Will update again..

so i took mine to the shop where i bought the phone and they sent it to samsung. it returned yesterday and they replaced the usb port and now its working fine, i hope the issue doesnt return. the warranty covered it as i made sure when i took the phone to the store that they knew this is an issue happening in a lot of A70's
