I'm wondering if anyone has suffered with and recovered from the sudden case of no charging/USB>PC recognition?
I've seen countless similar stories across the web, covering many of the Z Family. Some were simple reset jobbies, and I've seen as in-depth as what I'm assuming is an IC being removed, flux cleaned and re-applied (w ww .you tube. com/watch?v=ZyCeNfc99a0).
I purchased a new charger port and also a new battery, as I figured with all the insane constant burning of my pocket, it could use a new one. I'd hoped it was just a charger port issue, but much to my dismay, the issue still persists after fitting them.
I've tried every single button combination "fix", and all to no avail. Multiple leads, charger units, all that polava. Checked and cleaned connections with isopropyl alcohol, checked for burned-out looking mainboard components, at least those that are visible.
I was having minor inconsistent charging issues for a while, up until last Friday. I figured it was the USB port on the phone or the leads, and put it down to general wear and tear.
Last Friday I was at my mates house with super low battery, popped it on charge round his and I noticed it had died completely and kept boot cycling, like the charger was being plugged in and taken out over and over.
I took it out and tried it when I got home with the regular charger, and nothing. My phone is otherwise in mint condition and has been looked after since day one release in the UK.
I'm wondering if some super helpful person here would possibly have some other alternatives that haven't been mentioned, whether a hardware bypass or some trick that isn't amidst the countless cries for help out there.
Many thanks in advance.
Hello,
I have a problem when connecting to a charger it will go in strange charging mode that actually does not charge. It makes the sound like a charger is connected, no charging animation on battery though...
The problem for me it was the USB cable used for charging (i have changed 5 of them in 1 and a half years). Also same behavior happens when using a under 1A wall charger.
P.S. : The USB cables that i have changed they still work fine with other devices/phones .... but not with my Z5C. I`m not sure what but is definetly something wrong withe phone usb port (and it is not dirt).
no, but
I cannot get a usable USB connection to my computer, but if I hold Volume Up while connecting the USB cable to the computer, the charger LED turns red for a moment, then blue. It WILL charge in this mode, which I think is fastboot mode. Someone said it bypasses the charge circuitry or software, which makes me think that maybe I could go into developer mode and turn on OEM unlocking to see if I can stop it from trying to optimize charging. I also have not tried all the USB connection modes yet.
I tried to charge with this blue light technique on the wall charger, but that did not work. Just ran the battery down again and I could not boot the phone.
I know if I press Volume Down while connecting the USB cable to my computer that the charger LED turns green, but I am not sure it will charge in that mode. I think this is for flashing or something, but since my computer does not recognize the USB device no matter what I do, I don't think flashing is an option.
Oh, and when I do charge the phone with the blue light special (old obscure USA discount retailer reference), for some reason the charger LED flashes white every 4 to 5 seconds, but it seems to keep enough charge to get me through at least the day until I can charge again by same method.
Maybe we can keep pooling info here. I got the blue light technique from someone else on this site, so there are people here who know quite a bit about this phone, thankfully.
Well, I had that issue, too (at least it sounds pretty familiar).

Does your phone also believe to be connected to "something" all the time?
I fear there is some IC fried, although I never dared to open my phone.
My "solution" was to talk my local salesman into giving me a (used, but working) replacement phone, and I did not want him to find any traces of DIY
So, no, I never found a technical solution, probably they just scrapped my phone for spare parts, idk.
The root cause for my error (probably) was a faulty charger, therefore I am pretty sure I fried something hardware-like, but depending on your cause, ymmv.
Anyway, trying to clean your USB port, re-soldering the connector and/or replacing the battery sounds like being worth a try, anyway.
// edit: "cat /sys/class/power_supply/usb/present" used to always output 1, even when not connected. On my now-good Z5C this works like it should (connected ->1, not connected -> 0)
Hey people. I have tried all the tricks for several days. Tried several charging cables. Nothing worked for me. I just brought a new phone, and it came with a cheapo charging cable. Decided to plug it into my Xperia and it worked. Maybe a little fairy fixed my phone when I was out buying a new one. Anyway, I'm love my Xperia Z5. Using it right now. Good luck people

Hey guys.
Any time I connect the phone to my computer via USB, the phone's touchscreen goes bonkers. It wont register my touch in the correct location, it jumps around and registers button-presses that I never pressed, or won't register a firm screen-press at all!
If the USB is unplugged, everything zips along accurately.
Any idea what might be causing this, and how I might fix it?
Just a quick background:
I rooted and installed the lag-fix. I encountered a problem with the lag-fix, restored factory settings, and root/lag-fixed again. The problem cropped up after the factory restore.

That's wacky. Since you've already done it once, I'd just restore again and see if that fixes it.
Also... not sure if this is a side-effect of the factory restore, but guess what suddenly appeared in my Widgets list??

Using LauncherPro by any chance? It's been showing up with LP since Day 1.. If not, that's pretty darn cool then.

I've since reset the factory settings again; no luck. Still all wonky when USB is plugged in.
I'm considering taking it back to best buy and simply exchanging it for a different one, since I've only had it for a day. I would think that resetting everything to factory defaults would have fixed any software problem. Maybe this is a hardware problem that I just now noticed.
I have heard roomer, that if your usb is to low or to high of a voltage it will bork up the touch screen while plugged in.
it seems a common occurrence on many Android phones that use our style of USB port that if you use a 3rd party usb cable (i.e. one other than what shipped with the phone) as well as many 3rd party usb wall chargers that the touchscreen will either go bonkers or freeze up alltogether.
I've seen the exact same thing happen with my friends HTC MT3G and Motorola CliqXT using certain cables and chargers. Any cables/chargers that do this to my Vibrant do it to their phones too.
Interesting. I'm glad I read all this before I decided to take it back;
the laptop I had it plugged into is so fubar'd, that it would not surprise me to find that it has incorrect voltage...
This happens all the time on my Droid 2, Nexus and Fascinate. I just swipe very quickly and press lightly. However, no matter how many "tricks" I try it's still hard to flip through screens or open the correct app. Hardest task would be to navigate a website. Considering it happens on multiple Android devices and computers I never really put too much thought into it. Just figured it to be a Android bug.
Wow, never seen this. Now I do use the cable that came with my fascinate to plug into my computer, however car charger, wall chargers, and a USB charger (in my truck), I just use the cables from my Droid1. All my chargers are generics... Hmmm..
my htc touch pro 2 did the same thing when i used a gps car charger... screen went crazy
chargers
Ok. So for anyone wanting to know what's going on in the background to cause problems with your phone with crappy chargers....
I first discovered this with another touch screen player *cough*ipodTouch*cough*cough when I was trying to make a universal 4-port USB charging bay that would work with my sansa and my ...other player.
The specification that most device-manufacturing companies use nowadays for charging states that for a device to recognize a charger (and to start accepting a charge from the charger), the data pins must be shorted (connected together). This is what Sandisk, Apple, and several others are using. That is how I built my 4 port USB charger and it works flawlessly (with my sansa, ipod, galaxy, and Cowon S9).
NOW, somewhere floating around on the net are specs that state that some data must be sent/received through the USB's data cable (i believe it claims to need any 2.5V) which basically puts some resistors in to make a voltage divider.with the power and ground and data pins. THESE ARE BAD SPECS. They might have been legit in the past for some other device, but they are NOT what our phones need.
So some of the cheap, off-brand chargers are actually sending random messages to our Phones through the data pins (non-sense 2.5 volts). I haven't heard any reports of this damaging the phone or mp3 players yet, but whenever I plug mine into a charger and I lose the ability to control the screen, I get nervous b/c I know there is voltage on the data pins, and I don't know if it's the correct amount. So I get nervous
...does that make sense?
I had the Droid and the first time I saw that, it freaked me out. It seems to be an issue with touch screen android phones when they don't receive the correct voltage, whether because of a 3rd party cable, or a different computer voltage or something. I was using my blackberry mini usb charger and it would act like it had rabies. Nothing is wrong with your phone.
The charger included is plugged in next to my bed, and I'm using my Droid's USB cable in the computer without issues. That's very strange. I've never heard of this problem.

Sorry dude. It's not just android handsets, and it doesn't (seem) to have anything to do with the proper voltage. I've taken multimeters to the chargers. They are providing the proper ~4.5-5V range. It has to be the data pins.
Although, that's just the chargers I've had. Take a voltmeter to your usb chargers (don't touch the casing at the same time!) and see what their voltage is. But a low voltage just wouldn't charge your phone, and a high voltage would damage it.
Like a week ago my S3 9300 was taking longer and longer to charge now it won't charge at all, now is always stuck at 0% if i turn it off it will charge but very very slowly, i don't know if it's the phone or the battery maybe someone here had the same problem and could help me out a little, btw i have it with CM 10.1 thank you
Alejo
Had the same exact problem with my i9300, got it out of warranty repairs yesterday. Was using a custom rom, but the same thing happened when I finally managed to flash it back to stock (had to manually press the microusb-cable as hard as I could into the phone all the time in order to get the phone recognized while Odin was working, was the longest flash ever lol..).
Remember reading about cold solder joints etc before sending it off, so if your phone is out of warranty for some reason you could replace the charging port yourself. Replacement part costs ~5$ (eBay) and if you got the skills it shouldn't be too hard to replace.
EDIT: Actually mine didn't even charge when power off, so I was pretty certain it was a bad solder joint or some other physical problem.. Have you tried cleaning the usb port with pressured air or just blowing into the port? Could be some pins of the usb port blocked with debris. Also check your usb cables, there are those with 5 pins and those with only 4. Saw the difference in charging speed while the thing was still working.

Well actually when i plug the phone into the PC it will recognize it and i can access the files in the SD card and Internal Memory and everything at the moment it's turned off and it's charging.
I have the problem that the phone only want to charge with soms chargers.
I can connect the phone to the original charger or to a pc or any device without problems, the phone will charge.
Even with an old blackberry charger (only 2 wires, no data) and car charger can i charge without any problem!
But when i connect the phone to the htc charger of my old phone, or to an iphone charger i see the phone is connected but it won't charge.
When i open batterymonitor i see that the charger is connected, but the phone still use his battery.
I tried this with all kinds of charders and all kinds of micro usb cables. Then i thaught there was maybe a resistor or chip or something build in some chargers, because i couls only charge with chargers with 2 wire cables.
Then i took a usb extension cable and i disconnected the two data wires so only the + and - 5V cables were left,
but still no success. If anybody knows where the problem is, please let my know
with kind regards! Martijn
Hi guys I hope you can help.
I AM OFFERING A REWARD OF £10 GBP TO THE FIRST PERSON WHO SUCCESSFULLY ADVISES OF THE RIGHT FIX FOR THIS ISSUE *.
There, now I have your attention - brace yourself, this one’s a tough one.
About 2 months ago, I flashed DeltaROM 4.2.2 V2.2. I’m a serial flasher so I’m quite aware of what I’m doing. I had some issues with it that I tried to get support from them but they unfortunately didn't get back to/couldn't help me.
The original post is here in case you’re interested, the biggest issue being my S3 no longer charges correctly. If I plug a charger in from the mains, it will not register as charging. Once every 10 seconds or so, it will actually register the charger, but only for about half a second before it drops. It DOES however charge if I connect it to PC, Xbox or car (only wrks in the car if charging from a USB socket, using the in-car charger straight from the cigarette lighter doesn’t work). Basically, I can charge my phone off anything that isn’t directly the Mains electricity.
I’ve googled the hell out of this problem, only to find that posters will quickly dismiss it as faulty hardware; bad USB cable, broken USB port, bad charger, low voltage from mains – anything at all. But the bottom line is I do not have faulty hardware. Everything was absolutely fine until the very instant I finished flashing DeltaROM – I’m convinced something didn’t go right during my first installation since it was a bit rocky (read the original post for details).
After getting no answer from the Delta lot I jumped ship to LiquidSmooth (which is very nice by the way) but the problem remained. In one last attempt I started again from scratch. I used TriangleAway, formatted EVERYTHING (the kind that also deletes all your media) and flashed back to stock. Using Samsung Kies I 'upgraded' the firmware and I'm now on the latest official 4.1.2 release – and it makes me a little sad!
Just to back up the fact it’s not hardware related, I deliberately persevered with it to gather up as much information as I could, and here’s what I learned:
Why I'm sure it’s not the battery.
• I've tried two other batteries (3 total) and the problem exists with all 3
• The health of my battery is excellent
• My battery charges fine in other phones
Why I’m certain it’s not the Charger
• One of my chargers is only a couple of months old
• The charger I have been using is the official Samsung one that came with the phone, though I have 3 more – one BlackBerry one, a charger that came with my s1 (many moons ago) and two the same that came with mine and my gf’s phone. These are the plugs with a USB input on them,
• I have 5 chargers in all – BlackBerry, Nokia, Samsung (x3) ALL of which don’t work with my phone but ALL of which work with EVERY other phone in the house.
Why I’m sure it’s not the wall Socket.
• I’ve tried every plug socket in the house and even taken it to my parents and to work – same story.
• Everything else I plug into the sockets work just fine
Why it’s not a bad USB cable.
• I have 3 that I use. All of them will charge off of the computer, the car or the Xbox – they cease to work when I use them in the mains USB plug.
• They all work fine on every other phone in the house, regardless of if it’s in a mains adapter or a computer
• I am able to connect with all 3 cables to my laptop to view files.
Why I don’t think it’s a damaged USB port on the phone.
• It ‘does’ actually do everything it needs to do when plugged into my pc, Xbox or car. If it’s communicating well with other devices and harbours electricity correctly when doings so, then it can’t be the USB port since the way it gathers energy is the same.
So what gives? How can it be bat hardware if it works from the PC? How can it be bad firmware when I am back to Stock?
Thanks a million guys.
* Telling me to send it off for repair doesn't count. If it's something that I can do at home and it fixes my issue, the first person who gave that advice will be the winner. This does of course mean that if my phone is just downright screwed, there's a chance no-onw will win.
Have you tried to use a kernal like siyah kernal and change the chrging parameters for ac charging? (the Mah value for charging off wall socket...

Hi Koogly
Sorry probably should have mentioned this. I tried siyah and set everything to charge as much as it could - AC and USB. I also tried a lot of other 'fast charge' apps to no avail.
While the USB does charge, it's still quite slow at 460mA. Once in a while, the mains charge stays connected, and you can watch the mA level drop. It will start at around 999, but within 10 seconcd it will decrease down to 100mA, which is slower than the phone actually uses up energy.
Nobody?
This guide will help you:
- diagnose charging problems;- fix problems with the touchscreen while charging;I decided to write this because I searched for my problems on-line and never found a complete answer, just partial undocumented answers, essentially guesses from people, tried them, most didn't work, wasted a lot of time with trials so I hope this will save some people some time.
1. My phone says it's charging but the battery level drops or stays the same.
This is common when you are not using the original charger, but in order to check if you phone is actually charging you need to look in dmesg for something like this:
Code:
ab8500-charger ab8500-charger.0: VBUS input current limit set to[B] 500 mA[/B]
When connected to a computer (USB 2.0 port), you will usually see a limit of 500mA, and when connected to a car/ac charger, you will usually see a limit of 1500mA. If the charger is defective or not recognized by the phone you will see 0mA, even if the phone will look like it's charging it's actually not charging!
2. I get touch screen errors when my phone is connected to a PC or when charging.
It took me a while to figure this out, but it's quite simple, you need to check that your outlet is grounded. Once you plug your notebook/laptop/computer/charger into a grounded outlet all problems will go away. If you can't get a grounded outlet but still need to use your phone while plugged into your notebook/laptop remove the charger from the notebook/laptop and all will be fine.
The touch screen problems can also be fixed some times by using another charger, but this is a process of trial and error, for example I managed to get 2 chargers to work from 10.
thanks man... great post.... already clicked thanks button....
All of a sudden the USB port on my one year old V10 is having issues:
Won't "fast-charge" when plugged in to LG fast-charger. But does do and show that it is "regular" slow charging.
When unplugged, status bar battery icon still showing charging animation.
Does not switch (or give option to switch) to data when USB is plugged into computer nor does it appear as device on computer as it did before.
Battery is draining very fast, probably 2-3 times as fast as it should.
Also doing the following, don't know if related to USB issue:
When I power off completely, before, I had to press and hold down power button to power back on, and would also get a quick vibrate.
Now when phone is off, just quickly tapping power button for split second powers on phone and get no vibrate. Also when phone is off, plugging in charging cable powers on phone.
These issues just appeared out of the blue yesterday. Nothing has happened to phone - not dropped, exposed to moisture, didn't install any new apps, flash a rom, nothing new done to phone. It just started happening. :crying:
I would say that this is being caused by one of 2 things:
1. Bad charging adapter and/or cable. Either use another charger/cable, or buy an original LG fast charger replacement from somewhere like Amazon. 3rd-party stuff may or may not work out well, I would stick with LG if you want to play it safe.
2. The actual charging port on the phone is bad. In this case, no charger/cable will fix it. This will probably mean buying a new phone, unless you have warranty/insurance, the cost of getting it repaired won't be justifiable.
So far one of my 2 LG cables have gone bad, developed a split in the wire, now it charges my phone sometimes, but sometimes not. And it rarely works for copying files to/from PC. My other cable works fine for the most part.

I have 2 OEM LG Fast Charge 2.0 cable and brick sets, the one it originally came with plus another one I bought. I also have a second OEM battery and LG battery cradle. I've tried all these plus others I have and all get the same result.
I mostly use the cradle to keep the second battery charged and swap them out as needed each day, so I don't actually do much charging on the phone. I also use SambaDroid to move files to a PC, so the only real problem this is causing is rapid battery drain. I'm no expert but I'm guessing there's a pin in the USB port that is shorting somehow and that it's causing the battery to drain. Any hardware experts out there? I need this phone to last another year so am willing to try minor surgery if it would help and if I can find a good guide to follow.
Edit: SambaDroid not working in Marshmallow. I also sometimes just take out the SD card and pop it in a card reader.
