[Q] Hardware Fault: Device thinks its charging (volt sensor) - Sony Xperia Z Ultra

So for the past 4 days, my device often wont stop thinking its charging. So what I mean is that I'll plug it in (USB or Magdock) and it will charge normally. I'll unplug it, and the battery symbol and LED will still says its charging.
Once this happens, it will only charge off the magnetic dock.. So plugging in USB wont work, and no charge will occur. Its mental eh!
Its happened since I started using the magnetic dock.
What i've noticed is that reversing the magnetic charger cable, will make the device realise its not on charge. My laptop will also display a message saying that the... " USB device has been disabled due to excessive drain"
so somethings not right.
EDIT:
I have unlocked my bootload,
rooted,
flashed stock Sony ROM (with modified kernel)
flashed CM10.3...
Still doing it. Most def. is a hardware fault... SOB!

have flashed FTF's: .510 / .532 / .537 and they all do it.
So stands to reason its not software...

Sony states that you shouldn't use the magnetic dock with USB ports.
Try to reboot, for every small problem I've had. a reboot fixed them all.

Without effect firmware update

In my case,If you attempt to reboot, it must be "forced shutdown" before going any further in the repeat of the SONY logo.
I was out to repair to give up.

I assume you mean use both mag dock and USB to charge at the same time..
Yeah thats probably not a good idea. Too much volts going in.
I haven't done that, but there is clearly a problem with my device. Looking into a replacement from the store.

With the galaxy note this would happen if the USB port got any dirt in it. First place to check if you experience this. Take a cotton bud and some pure alcohol and while the phone is off, gently clean the pins then leave it to dry for a few minutes before turning it on. Dirt or dust can cause the pins to short and think it's charging.

Yeah that was the first thing I tried. However it happens on both USB, and MagDOCK, so its not a dust issue. There must be a hardware sensor that detects amp flow into the device, and must be a fault when amp flow is reduced/stopped.

ok so update.
Have sent my Ultra back to Hong Kong from where I purchased it. I'm guessing hardware fault...
:crying::crying:
And now I'm without my Ultra...

Yeah dude I know! I just sold my other two devices... what a jip!
I've got to admit that I was close to buying the Z1 last night.... but thats just too small, and too similar to the Ultra...
I'll have to go cold turkey and just deal with NO DEVICE! (man.. can't believe I just said that)

my phone havnt been in any wet area or near by water source...
the phone acting crazy...what can i do?
10.02.2012
found a solution
http://forum.xda-developers.com/showpost.php?p=22362533&postcount=18
ok i was able to make it work again but with the same problem as before
the battery is not giving the correct readings and i cannot charge it normally.
i was cleaning the USB Connector but it was not enouge..
the battery & the MTP icons are still ON and if i restart the phone
the problem remains the same (Yellow Tri) untill i connect the charger and the phone is up again..
one more thing is that the phone appears to be slow then usuel..
:| i have no luck with cell's am i? :\
That prob. Means your phone is too hot or battery is too hot. Phones shut down if they get too hot to protect themselves and it will do the same if the battery gets to hot. Since your phone is running slower I would say its your phone overheating. Try it with another battery and see if it works. And also remember water damage isn't just water it can also be caused by sweat, steam, and humidity. I know it sounds dumb but even taking the phone in the bathroom to listen to music while you shower will cause it too. Your mirror gets steamed up and steam is moisture. If another battery doesn't fix try to get it warranty replaced.

The outside of your phone maybe cold but the inside can be hot. Or it could be the temperature gauge inside the phone malfunctioning.

Hi,
I had the same problem, basically my case was that I had flashed a Frankenstein firmware and since then the problem had started for me. Once I moved back to the stock firmware, the issue is completely resolved.
Having said that, it did not occur to me immediately after I moved to a Frankenstein firmware, but happened after some time.
So if possible, try to move to stock firmware and see if the problem persists.
Thanks,
Vishal
I have also that problem with some custom roms, phone is old like 5 month, he was go randomly to crazy mode yellow battery , MTP won’t shut down and you can’t turn OFF phone. My friend have SGS2 and we have try to replace his battery but that didn’t help, in the end I have flash CM9 and now for one weak I don’t have that problem.
I think best advice is to take phone to service.
br
The problem gone by its own...i wonder how

my battery did the same thing, randomly works now tho?
But all i can say is, once the battery was 100% charged, I unplugged it then plugged it back in, It then took more charge when i did. Overcharged?

It was probably moisture shorting usb or lower motherboard usb connects to. This phone has that issue it seems and really miss slider cover from sgs1.
Solutions?
Cleaning usb port for obstructions.
Send to service.
Replace board by yourself. I did it just few days ago as I'm not under warranty. Take all precautions that you know what you're doing. Otherwise see above or below.
Put in your girls pantyhose and then in rice container to draw out moisture or original box sealed with some of those silica packets electronics come packaged with.
And yes sometimes it clears by itself as the moisture evaporates and if you're lucky that the power controller chip was not damaged permanently.

Same problem here .. If I turn off the phone is hard to start again. It does not recognize USB. Charged battery alert, not turned off. I thought it was a software problem and I returned to stock without root, but the problem remains. I start to believe it's a hardware problem (perhaps the USB port)
I'm thinking for a service, but I can not reset the flash counter, I have JIG and I'm not good with soldering .. I think in this occasion will have to pay ..

Confirmed, moisture in the USB port, had a green color in the connection
I think i'v found an temporary but long run solution
it work'd for me just fine!
1.Take a flat screwdriver and coat it with a thin layer of cotton wool
2. Insert the screwdriver at the bottom of the USB connection just below the "tooth" and bend the "tooth" gently upwards.
3. Use the USB cable to check that tooth bending too much and to check that the computer recognizes the connection.
that's it!

Touchscreen Calibration Issues (You Might Have This Issue As Well) [Updated 1/4/2012]

What the problem is:
The touch screen's calibration is off while the device is plugged in and charging using the provided stock ASUS charger. (No other chargers have been tested so far)

Test Protocol By N11:
Navigate to Settings/About Tablet/System Firmware Update
Try to tap "Check Update" while charging and while unplugged
Report any differences. Also report your version information.
Test Protocol 2:
Download "Touch Test" or "Multi-Touch Benchmark"
Report any differences while charging and while unplugged. Also report your version information.
Edit 1: I have discovered that this only occurs when the device is charging... Weird. Can anybody else try this? Download "Touch Test" and play around with in while charging and unplugged.
While Charging/Plugged In:
While Unplugged:
Edit 2: Seems like other users are experiencing the same behavior! Please reply if you are experiencing problems too!
Edit 3: So I purchased a stylus from my local Walmart to get a more accurate, less subjective "touch" The results are shockingly clear.

While Charging:
Same thing is happening with mine, but I cant hit the refresh button on the tabs in the browser (instead it keeps clicking the close button). I even tried my targus stylus and it still doesn't work.
I had a very similar problem with mine only it went much further than just what you guys are experiencing. In addition to what you stated, mine wouldn't even register anything at random intervals and in random spots on the touch screen. Here's a little video of just some of it http://www.youtube.com/watch?v=oywWUxPMeX8
I feel for you guys. I had to send my back. Currently awaiting a replacement.

has something to do with the voltage of the charger my epic 4g touch did the same thing with the wall adapter it came with started using a different charger from my old phone and problem went away...... I would be curious if all stock wall chargers for the prime do it or just some?
This is interesting. I had a Dell laptop with a defective charger and the touchpad would throw the mouse all over the place while it was charging.

I was going to try and pick up a replacement OEM TF101/201 charger from my local OfficeDepot (they actually carry these!) and try it, but they don't do opened box refunds...
Guess this is going back to best buy...
I think it has something to do with the backplate tingling/improper grounding,
throwing some static at the touchscreen grid making it think its being touched elsewhere.
See howfar off the touch dot is at various places on your screen.
You should be able to figure out a trajectory to where it is making "contact".

Exactly, try turning around your charger (so turn it by 180°)
I had something similar happen on my DInc when I plugged it into the wall and car inverter using my brothers Motorola cable and charger. The phone will just go wonky with the touchscreen. As soon as I unplug it everything would be copacetic. Try another charger and or cable.
So i wonder if its more likely that my prime isnt the problem and my charger or home wiring is wonky
I noticed this yesterday where I could not close browser tabs. Eventually I got the tab to close, and thought this was just some dust on the screen or something.
I have not had any issues before and use it a lot while charging (its technically my wife's so she gets to run the battery down and I get it after since I sit close to a outlet), and I was not having issues at all until the last firmware update (not that it is necessarily related).
I will try and run some more tests this evening and see if I can produce. I would think if this was a hardware issue I would have run into it sooner.
Did anyone have this issue prior to any of the latest firmware updates?

I'm honestly not sure. Prior to my device arriving yesterday, I found out about the newly released root method for the latest OTA so I upgraded as soon as I turned on the device. I do not have a benchmark for comparison.
I will be trying to invert my charger and I will also be trying a different location across town to see if maybe my electrical wiring in my home is causing voltage noise/grounding issues.
I have a solution:
Code:
if (Device.isCharging) { Screen.Touch.setOffset(-5,-10) }
done...

USB Cap

Dear Big Phone Niche Market Like Minded Friends,
I have had my Ultra for about a week now. I love it! With non-removable battery, I have formed a habit of plugging in my phone wherever possible...at my office, at home, first thing I do when I enter my car. If I keep a count, it would be like more than 20 times per day. Each time, removing and reinserting the USB cap.
My concern is whether that USB cap is going to fall off soon? Anyone know how sturdy or resilience that little string that connect the cap to the phone?
That string seems to be such 20th century solution, no?

You should check your phone. Charging 20 times per day is insane. The phone should get you at least 4 hours of screen time. Assuming you don't do anything else but use your phone since you love it so much, you should only be charging a maximum of 4 times a day assuming charging takes 2hours since your using the phone at the same time. 20 times a day means your phone is probably always plugged in already.
I suggest having it exchanged.

Oh no, there's nothing wrong with the phone battery.
I just have a habit of pluging in my phone when ever possible to keep it as much charged as possible.
Just in case, I'm stuck in a broken elevator for hours, I can play Candy Crush longer.
I didn't have this habit with any one my previous battery removable phones.....it just all started with the HTC One (non-removable battery)

It only cost HK$50 (US$6.4) to replace the cap here in Hong Kong's Sony repair centre, so its pretty in-expensive.

I got my magnetic cable today. It's a perfect solution. Thank you for suggesting it.
Out of curiosity, what would happen if I charge the phone simultaneously using both the magnetic connector and the micro USB?
(a) The phone would implode, vaporize, and generate a wormhole causing a temporal shift
(b) The phone will be charged up faster
(c) The phone will be charged up at regular rate
Thanks in advance.

[Q] i9300 hardware repair help, please

I've just been given two non functional i9300's for free, to see if i can repair them.
both have cracked screens, one appears to have water damage.
i've tested with spare batteries, and neither powers on, nor do they show up in windows when connected by USB.
whats the bare minimum we need for these to power on and be detected by windows, so i can determine if the logic boards in these even work?

the previous owner has disassembled them, and they had no batteries. using one from an i9305 has had no luck so far, basically just looking for advice and suggestions as where i should proceed.
if it was a PC i'd be done in seconds but fixing a phone i didnt pull apart in the first place is challenging.

yeah thats the same situation i'm in.
at the very least, one of the boards is showing 5W of power consumption when connected to a wall charger (which is connected to a power meter).
since the battery is charging, that implies something is working - but i'm getting nothing on the screen and not hearing sounds out of the speaker.

i cant tell which board came from which shell unfortunately, however this board/battery is charging in the water damaged shell, but showing 0W in the 'clean' shell.
backwards to what i'd expect. maybe this ones just a dead screen, and the other has some more serious, but better hidden damage.
edit: the 'water damaged' shell + board had a red charging LED show up, that went away when i hit the power button. didnt power on after that/the touchscreen buttons dont light up when touched.
edit 2: with my good battery the LED went blue and the backlit buttons lit up. i think this hardware combo works, and i just need a new LCD - will trst it out with MHL and see if that works...

Sent from my GT-I9300 using xda app-developers app
so using that test above (wall meter then MHL) i've confirmed that one board works, one doesnt. in either frame one board lights up the LED and the other doesnt draw any power or give any sign of life (assuming this is the water damaged one)
i've got one of everything (front + back camera module, speaker etc) literally all im missing is a LCD screen.
to ebay i go, this has been a good day
this just got hilariously fun.
i ended up temporarily using the LCD + digitiser from my i9305 (it works but hte back panel cant be closed) to sync up a bluetooth mouse to the phone.
now i can use it as a bluetooth controlled HTPC

[Q] Irregular behavior on the touch screen

Hello, I read that sometimes the touch screen do not behavior the way it should be. For example, touching it does not lead to the right response while sometimes the device responded without the user touching the screen. Has that issue been fixed yet?
happens only if u r using a cheap charger.
I don't have a huge issue, or an issue at all, but i just came home and i noticed that my Ultra doesn't like low temperatures. It's 4 C here and after i came home, i noticed that the screen was "ghosting", i.e the screen lagged behind when i swiped, like a shadow. It stopped after a minute, but come on.. 4 C isn't that cold. Electronics should easily handle down to -20 C without any issues.
I had major phantom clicks until. 290 rom, now have hardly any at all.

Thanks. Do I have to root the phone to resolve the issues?
How the charger affect such behavior?

Ah yes, Canada I've used it out in the cold before, but the thing that happened today hasn't happened before, so it's a little strange. It's still winter though, so we'll see if it happens again.

Phone badly ghost clicks if screen gets vapour on screen say if just woke up at night it's abit cold but hot air makes vapour come on screen. The screen goes mental then. Or if you have a dirty mark on screen like finger print. If you turn screen on it tries pressing different things where that mark is. This is only phone I've had problems with. I've never had a screen protector on it I expected the factory one to stand up to job but it is shockingly sh**. I don't want to remove it myself though. I want to try Sony in UK see if they will change it. And where I was always using micro Usb to charge as that is most usual basic way. The plastic seal has pulled off. Tbf in the couple months I've had it I've liked it. But would much rather have the htc one max

God damn it.. It happened again. I was out walking for like 20 minutes and the screen started to act up again.. A reboot didn't solve it until Android was fully booted, so I'm not sure what the issue might be. It can't seriously be the temperature. It's a couple of degrees (Celsius) here today and sunny, and electronics should easily handle above zero temperatures. Heck, it should handle -20.
I'm going to do a factory reset and put it in the freezer for 10 minutes and see what happens
The annoying part is that Sony has a repair center only 15 minutes from here, but I called them and they don't have the right equipment to repair waterproof phones. They can open it, but they can seal it again, so they would basically void my warranty when they fixed it.

It came back after 10 minutes in the freezer, and I managed to take some pictures of it.

It goes away by itself after a couple of minutes... This is clearly a hardware defect.

Well, yes and no Mine doesn't shut down or anything, but the screen simply washes out (like in the pics). It's back to normal after about a minute though, but it's really annoying. It doesn't even happen at temperatures as low as -20/-30, but 0-5 degress (celsius) (32 to 41 F). Hassan (our ZU Canadian) has even used his Ultra in -30 without any issues, so i guess mine's defective. That was what the support dude said at least (something something about a display part not being properly something something).
I really really don't want to be without it for like 4 weeks, but i don't know if i can live with this. Granted, the temperatures outside will rise pretty soon-ish, but i'll always know that the poor little fella is freezing its pixels off whenever i open a refrigerator
