[Q] USB Failing?

hello all,
Has anyone experienced this? Is the USB port failing or bad?
I plug my phone into AC charger. Most often the light goes on and it begins charging. Sometimes it stops charging immediately. Sometimes it will charge for a little while then stop charging. Mostly it will charge until I unlock it again then it will stop charging. I find that once it stops charging there is no one way to get it back. Sometimes its unplugging and replugging, sometimes its just waiting until it kicks back in.
I have replaced the AC charger, changed the plug im using and changed the power strip.
Weird thing is I have not noticed this with USB charging through the PC (however that charging is slower than my rate of use, so I just get less decrease).
Has anyone seen this? Is my USB port shot? Time to get a new phone?
thanks
P.S. - Used to be Rooted MIUI, now I am back to stock FRG83 w/ stock Recovery, Kernel & Radio....this has happened since I was Rooted for the past two weeks.

Any unusual heat, when you're charging?

No. And this is a new thing that started when I started using MIUI. But has not left even after a full wipe and PASSIMG install.

Screen issues when connecting USB/Headphone/HDMI?

Has anyone noticed an issue when connecting a USB, Headphone or HDMI cable to the D3, where the touch screen doesn't respond properly?
I had the same issue with the DX when I upgraded it to Gingerbread and the DX2. When plugging in a cable (even brand new cables), the touch screen doesnt want to respond. To use the touch screen, I have to unplug it first.
Since this is the 4th phone I have had this issue and it "seems" to have started with my DX when upgrading to Gingerbread, I wonder if it is a Gingerbread issue?

So no one else has noticed this issue? It is really irritating. I had the same issue with the DX/DX2 desktop dock. I had the dock replaced with the D3 desktop dock and have the same issue!
As soon as I dock, the screen doesnt want to respond correctly to touch. The car dock seems to work fine though.

I'm having the same problem and it was there pre and post root. When I am in HDMI mode, the screen is very laggy and sometimes completely unresponsive. If I unplug the HDMI the issue immediately resolves.

i've seen this sometimes, thought it might be the angle im holding it when the USB cable is plugged in.
Doesn't always happen tho and the dock works fine for me currently.

I have the issue with every charger except my car chargers... I also notice the problem if I plug into the headphone jack or HDMI port.
With the Droid X and X2, I had a similar issue (3 different phones) but with the Droid 3, I notice that not only does it not want to respond but it responds as if I touched somewhere else... It even responds as if I touched the screen when I am not even near the phone...
I took it in to Verizon and surprising enough, I was told it was normal!!!! Augh...

I do not have this issue. Just tried headphones, wall charger, and USB to my laptop and the screen was just as responsive as when the phone is unplugged. If you can narrow down a pattern I will gladly test more situations.

I noticed this when I was plugged into a brookstone international adapter that has a usb charger. Plugged into an old BB charger or my stock and it worked fine.
Actually I was in a bed and breakfast and my phone started to work on its own. Like it was haunted!!! Really crazy. I was able to repeat it everytime I connected this charger.

Have you tried a different setups then the ones you use? Like at a buddies or neighbor? If the issue following you around it could be a sign. As a former poster said with the charger cables the touchscreen goes crazy. I had a cheap charger that froze/slowed up my screen. I think it may be a grounding/noise issue (from a laymen not an EE).

HDMI
I've had issues with the HDMI cable plugged in. The video doesn't seem to be a problem, but the sound is very choppy on my HDTV. This was the case with both my wife's and my D3. I wonder if it is a setting on the phone or my 42" JVC TV is a POS.

I just had my D3 replaced due to an issue with the GPS. The replacement has the same issue. As soon as I plug it into any charger, the touch screen starts acting flaky.
When I plug it into my desktop dock (with or without power), the screen starts acting as if I had been pressing it and selects random things on the screen.
I have found that if I push a USB plug tight into the charging socket on the phone, the screen works fine.
Is it possible that Android 2.3 uses the extra pins in the USB and HDMI cables? If so, can this be disabled?

Use the cable and charger that came with your phone, if you're still having problems after that then you have an actual problem.

Hi,
I also have this issue sometimes when I charge the phone (original US charger with EU adapter). The screen responds slowly.

Charging problem

So I have a touchpad charging problem. When I plug a charger it won't charge. I guess it's bad contact,but sometimes when it's start charging the touchpad freezes so I do the reset and it's won't charging again.
Please help me fix that issue till I have some battery left...
All helpful posts will be thanked.

The charger itself is 2 pieces, make sure that they are twisted together tightly. When I first received my touchpad a loose connection in the charger caused it not to be able to charge.

Also, if you have some charge left, reboot into WebOS and see if it'll charge that way. There's an odd glitch that happens to some people (has happened to me, too), where it changes to trickle-charge even when using the stock cable and AC adaptor. Reboot to WebOS, and it'll trip it so it'll charge normally again.

This charging problem just started with my HPTP today.
It would only trickle charge with both the HP microUSB Charger and the Touchstone. It's never done that before with any version CM9 I've flashed (Both Alpha and Nightlies). It started happening today.
I decided I would reboot into recovery and wipe the Battery Stats in the Advanced section of recovery. Now it's charging and the percentage is rising again instead of slowly dropping.
But if it continues to trickle I'm going to Boot into WebOS and see if what ve6ay says will work!
Edit, yeah it's still on trickle and dropping with the charger.. Gonna keep it on WebOS and see what happens..
Edit 2: ok so, with the Touchstone, the tablet only heats up quickly and continues to discharge while on the touchstone with WebOS running.
It also continues to discharge while on the Touchstone with Android running after running WebOS like ve6ay suggested we try.
But with the Stock Charger MicroUSB connected and running Android (After running WebOS) it seems to be charging normally.

[Q] Will no longer charge using Dock cable

HI all,
C6903 would previously charge using an official Sony dock cord. Yesterday, however, the phone started making the 'phone flat' beepjng noise (it was close to flat), so plugged into the dock to charge. The beeping continued every few seconds, the screen rotation started playing up (I do have a screen rotation lock that hasn't been a problem) and the phone won't fully charge (the charge symbol is there, just keeps dropping. The error message "the connected power source is not sufficient. The battery is draining faster than it is charging. Minimise device usage while charging" popped up. It does charge VERY slowly if the phone is off airplane mode and the screen is off (it charged approx 30% in 10 hours, this way).
No rogue apps, etc. I reset to factory settings and the problem is still there. Phone charges fine using standard micro-usb.
Here in the NL, the carrier (KPN) send your phone away for minimum 2 weeks (& will not give you a replacement), and they will likely just test with the standard USB charger, which is fine.
Anyone experienced this & any advice would be greatly appreciated. Thanks, Adam

sounds like the cable is faulty, probably only one way to find out if you know someone with a dock - or just send the dock back to were you purchased it declaring it faulty

I've had similar issues, I solved it by rebooting the phone and plugging it in using sony usb charger until the charge is over 30%, after I got mine to 30% using usb, it then was able to charge using the dock.
you could check the dock with a multimeter, but there's not really much to the dock itself, so unless it's a broken wire, the problem is with the wall charger which the docks plugged into or the phone

Thanks all. I will check if it is the dock/cable or the power plug when my wife gets home - she also has the Z1.
Thanks again, will keep updated.
Adam

Yeah, sadly the cables don't last too long - went through 2 cables up until now and many more to come.

Tablet won't charge when on (android and Windows)

Hi everyone! Today a very strange thing happened... I was using my tablet with Windows, with a usb hub attached to use a simple mouse. This hub has a micro usb output, so that I can charge the tablet while plugging in usb devices (that's exactly the one techtablets uses in one of his videos about this tablet). All of a sudden it stopped charging, so I tried rebooting: NOTHING. Then I switched to Android, but still no luck!
I'm happy I see that it charges if it's completely off, but I don't think it's normal!
What do you suggest me? This tablet is fundamental for me, as I study with it!

Anyone who could kindly help?

Same here and notice this after your post here. Windows notice that i plug in the charger (screen brightness was different with pluged in charger) but doenst charge.

I'm thinking that it might be BIOS related... Unfortunately I can't update it (I have 2.02 version already), or at least sort of reflashing it, cause I don't have a usb keyboard... Can you make a try? Cause it's weird it happens on both Windows and Android! I also noticed that if I have it off, charging, right when I trigger the power button and the teclast logo appears, right before the choice of the OS, it stops charging..

i have same problem, do you resolve it for present? how do you use your tablet?

Mine was a bit temperamental and as described above for the 1st 6 months but now it will not charge even when off unless it is left for days. Then no where near full charge.

I had very similar problem on my old teclast c6j6 tablet a year ago .
It seems my usb connector in tablet was too loose after few months .
I opened and pressed ( squeezed ) usb connector and was work again fine .
For the time being I connect and disconnect usb cable very gentle on all my teclast tablet and is fine .

I have the same problem. The tablet will not charge while powered on and starts charging right away as soon as it powers off. I do not have to wiggle the cable or anything. ON = not charging, OFF = charging. It's very unlikely that this is caused by a bad connector.
Be careful when you use Android. If Android shuts down because the battery is low, the tablet will start as soon as you connect a power cable. The tablet starts up, stops charging because of this, shuts down because the battery is low, starts charging as soon as the tablet is powered down, starts up, stops charging, shuts down, starts charging, starts up, stops charging and s on. Viola: you have a boot loop.
I wrote about it here: http://forum.xda-developers.com/x98-air/help/dead-battery-bootloop-t3243993
There is a fix which requires some soldering. This is a YouTube video which describes the procedure:
