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?

Thank you so much for your advice. I appreciate it. My phone is still under warranty. The issue just fixed itself but not sure if its permanent.

Mine seems to have fixed itself also....been 3 days and no issues, following 10 days of rolling usb notifications.

 

Fido did send a software  upgrade  around that time.  Not sure if was fixed by a patch, or by usb cleaning though ...the unpowered  USB cord  tricks  was  working also., Maybe that did something.

Just reflash your phone with the latest SK6 firmware and problem is gone. I downloaded the firmware from sammobile.com, Happy A70 user :smiling-face:
