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.

Oops... launcherPro.
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

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.
So I was charging my phone and using it at the same time...and the charger doesnt stay in. its so loose....anyone else have this problem?
When my wife and I first got our Captivates her connection was really loose and would fall out. It turned out to be the plug itself, so maybe you can take it back to where you bought it from and ask for a new one.
This is my third Samsung android phone (captivate and nexus s), and it seems to be a common issue. I think its the cable though, as an HTC cable is nice and snug.

Have you tried plugging in another cable yet? Micro USB is a pretty common cable these days.
No problems with loose connections here.
In MicroUSB, the springs are moved from the device to the cable - so try another cable.
Does anyone know what might cause this? Is it a problem with my USB port? I noticed it with my home and my work wall chargers.
Before I call Verizon (whom it has been reported is out of Rezounds, and I'm unlocked/rooted), I was hoping for some advice.
Thanks.
An update -- now after I unplug it from an actual PC, sometimes the USB/Charge and USB Debugging symbols remain in the Notifications bar. Could that mean the pins on my actual microUSB port are defective? I've now tested with a 2.1A wall unit too, and every charger I've tried has been a new USB cord.
Oh and just to rule out software I tried in Safe Mode too, no help. Anyone have an idea aside from calling up Verizon (which I will do after my long weekend out of town)?
I've developed the same issue on both of mine I've had. My solution was to simply run a kernel with a Force AC Charge option built in. Have to be careful, however, as the option may cause excessive heating of the battery if you do any intense usage under charging status (playing a game, trying to run GPS navigation, etc.) It rarely poses an issue, but just a heads-up.
You should never use your phone while charging it alwYs turn it off and set it down. When you are charging ylur phone resistors and capacitors are heatingbup your phone now if you are on it talking on it basicly you are heating up the whole board and if it gets hit enough it will losen the solder from the joint and may cause a chip creep effect on the board causi ng varios problems that are very hard to troubleshoot

Try a different USB cable. I've had cables that would charge only, no data. Drove me nuts, I thought it was HTC drivers. Swapped cables fixed it.
The charger is presenting itself in a way that looks like USB. This is very common because iDevices will not charge at all unless the charger does this, so if a manufacturer wants to support iPhones/iPads, they make the charger in this way. Unfortunately, Android devices limit themselves to 500mA when the charger is made like this. Yes, many kernels have fast charge options that make the phone ignore this, but my advice is to get a charger made specifically for Android. Use the one that came in your HTC box as a wall charger if you can. Get the Verizon branded car charger...it charges Android devices correctly.
Yeah, there are many chargers that leave the USB contacts active. Thing is, I've had an HTC branded one that used to show AC at first turn USB on me... Everything else shows USB too unless I force AC in the kernel. Seems like some other condition, degradation or something.
Thanks for the responses so far. I have tried three different wall chargers, each with a different USB cable. Other phones show AC but not mine. At the moment, plugged into the HTC wall wart, I am being asked of I want "charge only" or "disk drive".
Could this be a software related issue? It was mentioned that some ROMS have a force - AC but I am on the newest non Global RUU, unlocked S On, and rooted with TWRP as recovery.
Bump -- is there any chance the RUU and then unlocking and putting TWRP on could cause this issue? Verizon is trying to get me to run a factory reset to "fix it".
Ugh.
Help! My Samsung Galaxy S4 won't charge or connect to a computer. I've tried different chargers, cables, plug in locations, car, 110, computer. There is no dirt. Connection is clean. I have a spare battery and both of them will charge on the battery charger. I have tried backed up roms. I have done a factory reset.
All of this and nothing helped. Am willing to try anything. Verizon is going to send me a refurb.
Help please.

Is there any indication of a connection being made? If not, you should just wait for the refurb. If you have rooted, I really doubt Verizon will honor the warranty on the broken phone. I wish you the best.

sounds like contacts are on the phone side are damaged or the micro usb port is damaged.
Have you plugged into to a pc just to see if it can "see" the device and connect?
You stated it cannot connect to a pc, so i would suspect you have a bad micro usb port.
if you can connect, its not the port, and try taking an eraser and gently swabbing the contacts on the phone side.
also, make sure when you insert the battery there is an actual contact established. sometimes when pulling/pushing the battery in and out, those contacts sink further into the device and finally when you insert a batter the contact is very poor. you may need a tool or tweezer to just VERY, VERY GENTLY raise the contacts if they sunk in to far......but be careful not to pull too hard/much they can snap and you will probably void any warranty......

I am having the exact same problem. I have replaced the microUSB charging port on the phone and it still doesnt charge with the new port. I'm not sure what is going on. NEED HELP BIG TIME!!!
I'm having the same problem as well. It has been like that for bout a month or so now. I googled it and it seems to be a problem with the s3's and s4's. I'm not so worried about it as I have a spare battery charger and I have the wireless charging receiver on my s4 and it charges my phone just fine.
I had this exact problem I believe...tried several different chargers...everthing. Try turning the phone off and see if it takes a charge. When mine was off it would show a gray battery and vibrate every 5-10 seconds. I figured it was an issue with the charging/usb port but all of the sudden my phone started charging normally and is visible by a computer. Lasted for about 4 days and have been in the clear for about 3 days now. No clue what went wrong or why, but try what I mentioned above by charging with phone off for a half hour or so and see if it has charged at all. If you need a new USB port, not all GS4's have the same port, so you must get a verizon specific one (ebay). usually run about $20..or $65 installed at a phone fixing center. I didnt want to lose MDK, so I was prepared to just charge externally, but ended up not having to...yet
It happened to me also. I had some intermittent luck with blowing out the port with air from my air compressor. But in the end it just stopped working and Verizon sent me a refurbished one.
I Also have this problem!
PLEASE HELP!
I don't know why but my international galaxy s4 running cm 10.1.3 stable isn't charging...
I plug it in to the wall and nothing happens its as if the phone doesn't even know it's plugged in...

Have you tried powering down your phone and seeing if that gray battery comes up and you get the vibrations (while plugged into charger)? You may need a new port, but since your under warranty, you could get a replacement unless you want to charge externally
S4 problem after update to 4.3
Hy,
I have a similar problem with my S4 (i9505), won't indicate if it is charging or connect to a computer, but while the charger is conected to S4, the battery level is increasing. When the battery is fully charged S4 is SHUTING DOWN!!!! And it wont start by pressing ON/OFF button, it will only start after I press Vol Down+Power, after goes to Download Mode and press Vol Down .
Tryed in many ways to fix:
- restore-
- hard reset
- changed te battery and charger
-i\ve changed even the usb port (flex cable) and =no results...
All problem started after update to 4.3.... and it is not an isolated case too many people complains about this 'awesome smartphone' with 'awesome issues' .
So, if anyone have any ideea how to solve this issues....
{Sorry for my bad english}
Had the same problem...lasted for about a day, I had to take a dry q-tip and clean the charger and the port where the phone charges and was able to get it working again. If you are rooted and are having issues go to amazon or ebay and get a wireless charger and it should take care of your problems as well

Ok....wireless charger...but what about syncing with the PC?
Now I have JB 4.3 , for a custom ROM I need to use usb cable to connect to PC, rigth?.
For me it is annoying, because I do not know for sure if this is caused by updatind to 4.3 or is a harware problem.
My wife's phone had this issue last night and this morning; charger or computer, it wouldn't charge. I turned it off, took out the battery, SIM and uSD card and put them all back in. After that it started charging again. I don't know if this will solve the problem long term, but so far it seems to have done the trick...

Lucky you...I did more than that, but no result in my case. I found on ''community.verizonwireless'' many more similar cases where ''customers support'' tried to avoid giving the answers for a real solution.
Well, our luck didn't hold. My wife's S4 wouldn't charge again last night. I tried another Samsung charger and a different cable but it wouldn't work either. When we left the house she tried it on the car charger and it worked great. Trying various other chargers we found that a kindle charger wouldn't work, but other third party chargers would. Even her PC USB port seems to work and she doesn't have the drivers loaded. For now she replaced the Samsung charger and cable that came with her phone for one that came as part of an accessory pack and it's happy again.
I have no idea what's going on with the thing. I asked one of the guys at the Samsung booth in Bestbuy and all he had to offer was reflashing the ROM or un-rooting it and doing a warranty exchange...

Can you check, please, if your new data cable has 4 or 5 pins(look to the side that connects to your phone )?
My first s4 done this. So I ended up with a replacement mdk phone after I figured out if you bend the lil piece in the charging port of your phone (not too much BTW) the charger will slide into the port as it's meant to.
Sorry I can't remember the tech term for that lil pin inside the charging port.

Just going to throw this out there....
I think the S4 is compatible with QI compliant wireless chargers. Amazon has some that are only $20... might be worth the purchase.... hell if I didn't have this tank of a case on I would buy it.

Thanks for your answer, but I already did that....I even changed the flex cable with charging port, no luck for me.....
I think this issue it is not hw problem because, look what I did today:
-I put a new Rom , so I used MIUI FOR I9505 from http://forum.xda-developers.com/showthread.php?t=2306650
And now it behaves even stranger:
S4 is ON and wall charger is conected, (LED IT IS OFF but BATTERY IS BLINKING and is charging ) after battery level go up to 100% and disconect the charger, the LED STARTS TO LIGHT GREEN!!!!
So, now shows that is charging when charger is NOT connected?

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
