Re: Can't connect or charge when linked to a computer

Same problem here.  Charges just fine from the wall but wont connect to any pc or android auto through multiple cables.  Tried multiple cables.  Tried uninstalling many apps.  Can't repair with companion software as it won't connect to a pc.  Worked fine for many months and now nothing.  Phone likely out of warranty so no help there.  This is my 3rd or 4th sony phone and likely my last as this is ridiculous.  Been at least two android updates from Sony since this started with no fix.

Re: Can't connect or charge when linked to a computer

Called support about this issue.  Waste of time.  Had me download a PC driver from 2017 stating it would allow me to perform a repair with the companion.  After installing the driver, device manager for the installed driver says "This device cannot start. (Code 10).  The specified request is not a valid operation for the target device."  So it's likely installing this driver did nothing as it is not running properly but i tried the repair anyway.  Start repair from the xperia companion, checked the device cannot be detected box, unplugged and turned off the phone and held volume down while plugging it back into the computer.  The companion says to wait for it to advance to the next step.  Nothing after 10 minutes.

 

Called support again and they said i should send in the out of warranty phone for a repair.  Don't feel like paying for this bull crap that they screwed up with their updates (phone worked flawlessly for 9+ months with both my PC and andriod auto then an update and now nothing with mulitple pcs and cables).  Especially as a factory reset results in the same detect usb devices greyed out and no usb connectivity and their own phone number in their own email isn't active anymore.  Think im done with sony.

Experiencing the same problem here. The problem is still not fixed with build number 47.2.A.10.62.

Go to Settings --> System --> About phone --> click on build number 7 times in quick succession. You will see that developer options has been enabled in system settings.

 

Go to developer options --> scroll down to Networking --> click on Default USB Configuration --> select "File transfer" .

 

Connect to a computer and the phone will be recognized.

Re: Can't connect or charge when linked to a computer

Thank you for your suggestion, however this has been suggested many times by multiple sources. The USB settings are grayed out because it doesn't seem to know its even connected to a computer. It is therefore impossible to do what you suggested.

 

There are multiple threads on the forums that describe the same problem. Maybe one of the mods or someone from Sony can merge them. 

 

According to the Sony support chat it requires you to send in the phone for repair to solve the problem. To this point it is not clear if this is a software or hardware issue. Maybe soldering from Sony could elaborate on this and shed some light on the problem.

Re: Can't connect or charge when linked to a computer

Hi @otandreto. Just to clarify, my suggestion is not about enabling USB debugging mode . This method doesn't work (I've tried it).

If you scroll down a bit further in developer options, there'll be a 'Networking' option under which a "Default USB Configuration" options exists. Clicking on it will reveal other options from which "File transfer" is to be selected. These options are not greyed out for me and this has solved my problem. All the other methods I tried didn't work.

Re: Can't connect or charge when linked to a computer

You are right, they are not grayed out. Although they still do not work as those settings will only be active once the phone detects a computer. As long as the phone doesn't even detect that, there is no setting that will restore the functionality. So no solution here.

Re: Can't connect or charge when linked to a computer

Hi,

 

Just to add some informations. My setup still doesn't work after updates (47.2.A.11.228). Usb options are greyed out since i had upgraded my phone to Android 9.

 

I always use the official usb cable for charging. Before the upgrade with the same cable i was able to transfert files with windows 10 and Linux.

 

The only way i have to tranfert files today is to send them on an usb stick or via bluetooth (so sloooow).

 

Many others customers have the same behaviour with Android 9 on other phones. So, maybe it's broken with some setup, or maybe it's more strict and some usb cables are not working anymore. If it's broken maybe the next major version will correct it, but my phone will not have it, Android 9 is the last supported version.

If it's the cable, maybe have a try with some usb3/C cable. The official seem to be usb2/C. So ... have a last try with this ....

Re: Can't connect or charge when linked to a computer

Well to give an update on my situation. I got advised by both Sony and the reseller to have it inspected at an official support center. So I did. After a week and a half I got the phone back. They had to replace the motherboard to fix te problem. Now it works with my original OEM usb c cable again. So funtionality is completely restored. They didn't tell me the cause of the problem. But if the mb was replaced, it must have been faulty hardware.

 

@octavinus, if your problem is the same as mine, it shouldn't charge when connected to the computer but only to regualr usb charger. If so, then you might be looking at a mb replaced as well. But that is is impossible for me to know. I suggest you try some different cables and maybe try your cable on a different phone (from a friend or family member) to eliminate the possibility of the cable beying faulty. Hope you find a solution soon.
