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
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.
hi all,
im using koasfroyo 2.2 v35-1. all of a sudden cant mount when i plug into computer, been researching like crazy and found something i want to try but cant find the setting on my phone. "go to Settings>>Connect to PC and verify Default connection type " dont have connect to pc under my settings menu anywhere!
anyone know where the default connection type is located in this rom?
thanks
Does the icon show in the notification bar that the usb is connected? If so, what I would try is using a widget to connect the usb and see if that works. Your Power Control Widget will have this settings and you should have this as it is a part of the Settings app. Just long press on your home screen and open the widget from there. If that doesn't work, then there might be a bigger issue we need to track down.
nothing is in the notification bar, went to a friends house today and plugged it in his computer with his cable and my cable and still nothing, just charges the phone. i wonder if last time it worked (2 days ago) i didnt unmount before i pulled out usb cord, i normally unmount before i unplug. could that cause a problem, the one thing i havent done yet is format my sd card. tried 6 different computers since it happened, same result on all.
Hmm. I actually had the same thing happen to me and I was freaking out. I used another USB cord and it worked fine. I'm not sure what happened to it, whether it got pinched, cut it with something accidently, or rolled over it with my desk chair, but yea, that was it. I would REALLY be surprised it if had anything to deal with the unmounting it just by unplugging it. I've done that more times than I could even remember. Multiple times a day for months and have never had any issues, or have heard of others. So, try the cord thing next. It's always best to eliminate problems by going through the easy and obvious things first.
Have you ever use wired tethering or just have the app? This has been known to cause the computer recognition not to work. If you have recently use wired tethering try rebooting. If you just have the app installed remove it and try to connect.
Yeah, try using another USB cord. The one that came with my phone stopped working at some point (I would physically connect it and nothing would happen.) I tried a few other cords until I found one that works. Good Luck!
Ok will try another cord tomorrow. Actually I tethered for the first time ever on Saturday night, just seeing how it worked with ubuntu. I used easy tether lite. That was the last time phone worked plugged in. Tether worked great, unplugged and moved my computer into the garage, since then hasn't mounted. But before I started this post I wiped dev & data and reinstalled v 35-1 but didn't clean my SD card.

Since you have rebooted, and haven't mentioned wired tether app for root I don't think what i proposed is the problem. I have also had the same result from different usb cables as said above so hopefully that will remedy your situation.

I think your phone usb connection might be to blame not the cable. Try moving the usb end while its plugged into the phone (up, down, left, right) to see if it clears the issue.
I has the same problem a few times after tethering but if you reboot phone and computer this should work of its not a wire problem. Also what apps do you have running on the computer when trying to mount... IE... earlier tendering programs or HTC sync

Hey guys, thanks for dropping by.
I have a very wierd problem, that I just cant figure out.
It all started the other day, when I found my tablet dead after having been left on and charging during the night. The tab was dead, and I feared the worst. After having left it on what seems to me like a trickle charge for several hours, I managed to get it up and running, and the tab seems fine, it was just completely out of juice.
But my troubles are not over. Whenever I'd connect the tab to the wall charger, I'd only get the red "X" symbol in the corner, and it would say MTP Initialize, even though its plugged into the standard OEM wall charger that comes with.
When I connect the tablet to my computer using the same cable, nothing happens, and by that I mean nothing. Computer doesn't start the connection process at all, its not recognized in the device manager, nothing. Not even Odin can see the tablet when I put it in download mode, the tab keeps saying "Waitting USB Cable..."
Tried this on 2 computers, still no luck, even using a USB plug on the motherboard instead of front-usb.
Now, the tablet will "trickle charge" from both the wall charger, and the computer, but nothing else happens.
I figured it could've been the ROM, so I got the latest ICS Kanang ROM downloaded, transferred it to my tab using Bluetooth, and flashed this without hassle, but the problem still persists, only now showing a regular charge icon in the lower right section, but it is still only trickle charging as far as I can tell.
All I can figure is a defective USB cable, or even worse, defective port on the tablet itself, but I'm not sure. I've ordered a new cable from DealExtreme, that will hopefully arrive sooner rather than later.
But seeing as the tab is hardly 4-5 weeks old, I find it difficult to believe the cable is the problem.
Anyone have any ideas? I'm all out at this point, so any pointers is very appreciated. Thanks.
It could be the cable. It's the part you have used in each situation. I'd wait for the cable to arrive and test it with the tablet when you get it.
Sent from my GT-P7510 using xda premium
Hey, thanks for the reply.
Yeah, I really really hope this is the case, time will tell, DealExtreme is not the quickest dealer. I'll update when I get it.
The new cable came from DX, but I'm afraid it showed no difference on anything.
The cable is working just as the original one, so that's not the problem.
Anyone have any ideas?
I guess my main goal at the moment is flashing it back to stock and un-rooting so I can get it repaired.
You mind posting a screenshot, it's kinda hard to imagine what you see by what you read For all I know my imagination went from a red X to the corner to something like an X off battousai's face.
Then again, I'd be glad to help, provided you post screenies, would be a major help
Ah, yes, I will take screenshots of anything you want to see.
Right now im on ICS preview, and these are some snapshots WITH the cable connected.
The red "X" I'm talking about you can see on the first picture on the charging icon, this happened even when the wall charger was connected on gingerbread/overcome experience rom.
The other pictures you can see it says discharging. Now, this was taken when connected to the computer, and I guess that's normal, but it also happens exactly the same when connected to the wall charger that came with the unit.
If you want screenshots of anything else, ill get it asap!
I took a poorly image of the tab connected via USB, to my computer with Odin open, hopefully you can see what it says.
If not its just what happens, I don't get further.
By the screenshots, Is the language Swedish?
Then again thanks for providing the screenies
In your first screenshot that could be part of the theme, or was it never there previously? I don't really know if it's not charging or that's supposed to be the charging icon, because for some odd reason on ICS preview I don't see that red icon anywhere.
As for the tablet, the reason why you aren't detecting it seems as though you don't have the drivers on the PC, I don't know if you installed them or you didn't mention it because I never found it being mentioned in your reply. I know it sounds silly but the same thing happened to me when I was using the tablet, (originally my 3G series belonged to my dad who knew nothing about modding so he just gave it to me and said, "do your thing" ) He did also forget to mention that you require to have the drivers to detect it via Device Manager and MTP in general, shortly the COM port will show up aswell. Perhaps re-installing the drivers should do the trick?
Made me wonder how did you install ICS in the first place if you weren't able to have it read? But I realized you could have downloaded the zip file via the tablet, On another note, how did you install CWM in the first place? o.o
Hehe, almost! Its in Norwegian on the honeycomb picture.
The red "X" would show up whenever i was connected to the PC via USB, to indicate its not charging. It will however "trickle" charge, and take 24h to charge fully with no usage and turned off.
Yes, the red icon is not on ICS, it just says not charging in the about page, as you can see from the screenshot.
Drivers have been reinstalled two or three times on two different PC's, I don't believe this is the issue.
When I bought the unit, it was working 100%
USB was okay, I flashed and rooted the unit over to "Overcome Experience".
From there I transferred ICS preview via Bluetooth and installed that way.
Have you tried factory reset to make sure all modules are reset? Maybe the USB charge module in Overcome is conflicting.
Yes.
Factory reset 3-4 times on the two different roms. I've reset everything I could find, without success.
Perhaps it has gone faulty with the tablet's plug in port, someone had the same issue although it was his wire that was at fault, it detects the charge via USB but not enough volt's to be detected by the PC, has it been grounded? Seem's more likely :| Might have to get it checked in your local center perhaps, It's how I mentioned that any metallic object is able to relay electricity despite being broken or not, you may have a broken pin for all I know :|
Hi,
I'm having exactly the same issue with my 1 month old tab 7+. I tested it using my bosses charge cable and there is no issue so I need to go to the service centre for a warranty replacement on the cable.
Hope you sort out your issue soon!
Thanks, but I don't think I have any other choice to deliver it to Samsung Europe as a payable service to get it fixed.
Purchased on a American store, and I doubt they'll take it back with flashed software.
I'm not sure really, I'll see what I end up doing. Its not the cable, that's for sure.
About 3 months, I had some issues connecting my i605, rooted, running Jelly Beans Build 13 ROM to my PC (windows 8). It started with not being able to detect the phone at all, it then evolved into spotty charging, and the phone randomly going into "car mode" because from what I could tell, it thought it was docked. So I figured this was due to a faulty charging port, so I took it to a renowned shop and got the port replaced. Prior to getting it replaced charging got better and car mode (which was incredibly annoying because it caused many stutters and force closes from constantly turning on and off in quick succession) pretty much disappeared completely except for once. Since getting it repaired, charging has improved, and car mode has yet to appear, however it will not transfer files still. The PC is 50/50 with recognizing the device at all. Sometimes it will show up under "My computer" sometimes not. When it DOES I can explore the SD card (sandisk 64gb class 10) fine, and the phone onboard memory, but when I try transferring TO the phone I get an error that says, "The device is not responsive, or has been disconnected". Now when transferring from the card to my pc I get another error, but that error is also 50/50. I just tried it and can transfer from the card to my desktop fine, but not vice versa EVER. Anyone have similar issues or even better, a solution?
EDIT: I tried changing the ROM's extension to just .file and it moved over fine. This leads me to believe it for what ever reason just will not transfer .zips(seeing as that's all I've tried transferring, and .file worked fine).

You say Car Mode still hasn't started up since having it replaced? Could it be an issue with the replacement? I have replaced ports on plenty on phones, doing it myself not taking it to shops, and have never had this issue but it could be they didn't do a good job, didnt use enough solder to fill the PCB holes, and it isnt making contact the entire time.
It may also be a driver issue but to me it sounds like maybe the replacement isnt a quality replacement, maybe he didn't use enough or used to much solder, or there is another underlying problem with your phones MoBo that is causing this.

No, not having car mode is a GOOD thing. Car mode was giving me hell. It'd randomly at anytime just start turning on and off rapidly. The only remaining issue is the transferring of .zip files.

Have you tried troubleshooting this issue using just the micro sd card in a card reader?
It could be that windows 8 hasn't the proper drivers to interface with the phone.
Also, a cheap workaround could be to transfer the zip files to a flash drive and
use an otg cable to connect flash drive to the phone for transfer there. If the zips transfer that way I would suspect
the windows 8 pc samsung drivers to be the culprit. After considering all the facts, though, you might want to return your phone for a port repair again. My curiosity got the better of me. Does it charge with the factory wall charger with no interrupts?

You mean put the micro SD into an adapter to make it a regular SD card and then try that? If that's what you're talking about I've tried that too, for what ever reason that card (64gb sandisk class 10) is read only. I can't write to that card. Maybe its the formatting or something but if I recall right I researched why I couldn't write to it months ago, and though it's very fuzzy I feel like my research amounted to: "you're **** out of luck". Trying with an OTG might work, but I'd have to get an OTG cable first. Thing is it USED to transfer .zips. That's how I rooted and placed ROMs on my phone. It's only recently after all this charging port problems that transferring became an issue. I thought it was simply because the port became loose and the "connectors" (excuse my lack of hardware-speak) were touching and then jiggling during charging or unplugging the phone or whatever caused the port to lose connection with the rest of the phone. So I blamed a defective port for all my issues and decided to replace it. Now since it's been replaced all past issues are gone, except this transfer issue. And to answer your final question, it did not prior to the repair, it does now from what I've seen.
I hope this is the right place I joined the forum a long time ago for help with an old Android phone hopefully I can find some help with this here too.
I bought this about a year ago:
https://www.amazon.com/gp/product/B085H9H57Y/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
I used an SD card with Emuelec on it had a bit of fun with some retro games and android games, and installed some software to watch videos with it. I used it for about 3 or 4 months then set it aside to focus on other things. Cut to around the beginning of the year I get a new Samsung 4kTV and wanted to hook all my stuff up to it. When I connected this and plugged it in I got stuck in a boot loop. It worked just fine up until the last time I used it and now the boot screen starts discolored for a couple of seconds then changes to its normal color, tries to load for about a minute and then resets. Even with my Emuelec SD card in, it tries to boot, runs through some of the file installation for what looks like the first boot and then resets.
I download the tools to make the stock firmware SD card to reinstall and it seemed to go through the whole process just fine without rebooting, but when I eject the card and restart the device the same thing happens. I have the one program that's supposed to let you connect to the deice through USB to installed the firmware again but it doesn't appear to be recognized by the software (it's likely the cable I'm using isn't a USB2 rated cable or maybe I didn't install the drivers properly) I've tried a couple of different adaptors because some people say maybe the adaptor is junk but I don't have many options with barrel connectors that even fit. I've seen people talk about shorting connections to break a loop, but I'm not an electrician and don't know the first thing about that, That being said I did try to open it an I can see the bottom of the board but I'm not sure how to even get it out of the rest of it's plastic case without breaking something (I think I need a small wrench to disconnect the port for the pointless external antenna.)
Anyone think there's any saving this or should I just call it a loss and move on?
(Update!)
I continued to search for solutions in the meantime after posting this and eventually bought a new adaptor. Without clear information I assumed the adaptor wasn't the issue, but I eventually just on a whim I tried another adaptor I ran across in my pile of electronics that caused the device to suddenly power on and escape the boot loop. Despite fitting the plug perfectly the adaptor I was using doesn't have very legible writing so the actual output can't be read, but this new adaptor seems to be a 12v which seems out of the ordinary to me but what ever it's original use it appears I'll be using it for this case. I'm glad I didn't seem to do any damage to it while searching for a fix (other than the reformat that cleared out my apps). My thanks to anyone that took the time to read this even if you had no advice.
