[Q] [Help]. Strange issue with micro USB port.

:crying:
I got my problem yesterday. My phone (GSM version) suddenly didn't charge when I plug with charger.
I try to connect it with PC, PC not recognized it, still not charging.
Reboot to bootloader, all fastboot command work fine (this thing is what make me believe my microUSB port doesn't die). So I flash stock 4.2.2 with Gnex toolkit.
Now the phone charge, adb and mtp work fine when I connect it with PC, and with wall charger nothing happen when plug it in. I did try some charger, it's same, still not charging.
Please help!
p/s: Sorry for my bad english but I hope you can understand what I mean.

There have been issues with the MicroUSB port in some Galaxy Nexus phones. I know this because I was involved with a thread over on the Android project forums having to do with very strange issues of the screen coming on all the time. The discussion is here: http://code.google.com/p/android/issues/detail?id=39625
We finally seem to have resolved the issue by very gently bending the tiny pins inside the phone's MicroUSB port upwards towards the screen.
You have not mentioned the same issue, but I can imagine that all sorts of strange activity could be attributed to a faulty MicroUSB port. You should have a look at comment number 161 in that thread and think about trying that. Be very careful! Be very gentle. If you break it, it;s not our fault! ;=)

Have that problem too and a my USB cord wiggles soon I have put my phone in position to charge

I remember I had a similar problem like this and I had to change my usb cable. Now I am using my Kindle cable for my nexus as well :laugh: so just try to change your cable and see does it work

I've been through 3 cables so far. The OEM, an HTC ,and I'm on a generic one now. Works for now

Charging with USB Cable

I had recently purchased the C6502. At work I do not have AC power outlet to charge the phone. So I generally used to charge my old smartphone (LG Optimus 4X HD) with a blackberry USB cable. I used to charge my old phone by connecting to the monitor's USB port using the blackberry cable. Though the phone showed as "Slow charging", it served the purpose.
But now using the same Blackberry USB cable and the same USB port, if i try to charge the C6502, it just lights up the screen and does not show any charging indication or the notification LED light.
Am I missing something here or the phone charges only with the original Sony provided USB cable?
Note: The same USB cable and the USB port work perfectly fine for other smart phones my colleagues are having like Galaxy grand, Lumia 610, HTC Desire SV etc. Of course when connected to the usb port all these phones are showing as slow charging, but they do charge slowly. But my XZL does not even charge. So I am definitely sure the cable and the port are perfectly fine.
Is there a way I can charge my XZL with the USB cable using the USB port?

Let me explain it more clearly.
At my work the USB ports on the CPU are disabled. But the monitors are having USB ports which can be connected to the CPU through another cable, so that USB devices can be connected to the monitor's USB ports insteading of leaning till the CPU under the desk. But those ports are not connected to the CPU so the ports on the monitor just act as a power source but not as data source. So we use the monitor's usb ports for charging our devices like phones, ipods etc.
As i had already told that my XZL screen lights up when connected to the port using the blackberry cable, but no indication of charging as well as no LED light. Same case with another colleague's Xperia SP.

as simple as your device does not detect any pc therefore it doesnt accept charging depends from phone to phone

So sony does not support "chaging only" mode using USB cable. How pathetic !!!. Supposed to be a "Smart phone" but really do not understand why cut down basic features.
Can anybody confirm if this cut down of a basic feature is a standard for Sony phones?

USB charging
I have observed two things -
1) Yes, it does not charge in some cases. I have a power bank cable, with this cable it charges for some time but then it just stops charging without any reason. If you reinsert the plug, it starts charging again.
Other times, it does not charge with USB ports, for example my car music player's USB port. But what I have noticed is, if USB connectivity mode is changed from MTP to MSC or vice-versa it works.
Also some cables do not have two spring notches, and fit quite loose. In such cases pushing cable vertically up or down gets it charging again. But this is very very rare case.
2) I was not able to charge it from front USB port of my PC, but when connected to back USB port, it was charging fine.
My conclusion is, it does not charge if charging rate is too low or mode is incorrect.
I would suggest, try with original Sony USB cable in your office and check if it works. If still it does not, change connectivity mode. Else its a cable issue(not exactly, but phone and cable have some mismatch).
PS - I had similar problem with my chinese tablet. Out of more than 5 cables, It charges with only one cable from Nokia(it does not even charge with original tab USB cable ). I think there are separate data pins and power pins. But data pins can double as power pins. I think there was some damage to the tab USB pins, because of which data pin no more works as power pin and hence it does not charge and requires cable having power pins. Can somebody throw more light on this?

Relax its just u need a pc on to charge it it happens in my case too n my phone works fy9 with any cable

No longer charging from USB to Micro USB cable. Please help!

Hey Guys, wondering if there has been some update that has rendered charging from usb to micro usb useless? I have been pulling my hair out. I thought all my micro usb cables had gone bad, but then I noticed the HTC charges with no issues when I test with the same cables. I notice the Note 2 will now only charge with a brick type adapter. I use the HTC power adapter charger to use on the Note and it charges fine. My Note 2 is international and is rooted.
Can any of you guess what might be going on?

Nevermind.
I found it it was the usb ports on the surge protector that has gone bad.

Can't connect to PC except for charging

Hi. I wanted to flash Oreo RUU and root but I cannot connect the phone to my laptop except for charging. I get a message saying "USB device not recognised". I've tried 2 cables (HTC and anker) 3usb ports but to no avail. I've tried installing drivers through HTC sync but it doesn't work. I've tried to connect in bootloader, recovery, and download mode but same problem. Can anyone kindly help me? Thanks.

may be due to faulty c type connector on phone

Any way to test that?

If it does not recognize in PC try with an otg cable and pendrive. If it also doesn't work then it could be the connector.

Hmm I guess I'll try to find a USB C otg. Thanks for the advice. Didn't think of that.

is fast charge still working? on my htc10 the usb connector died after 15months and it started with fast charge not working and the pc connection was very unstable. In my case it was warranty and got repaired.
