Hi.
My x10 mini pro has terrible touchscreen issues while being on dc charger.
For example arranging icons is totally impossible and the upper panel keeps on showing up and stuff.
As a result the phone is almost unusable as long as it's on charger. But when charging via pc everything seems to be perfectly ok.
Anyone has the same problem? Or did I just get a defective device/charger?
Also, my battery lasts for only some 4-5 hrs. I've had the phone for 4 days now, so i'm still givin it quite a business, but 4 hours? Seriously..
Well I don't think that is normal , you better take it to where you purchased it and tell them about the whole thing that's not normal.
Thanks, the thing about the touch screen really *is* weird. How about the battery persistence?
Is your phone Android 1.6 or 2.1? I have the same problem before but the problem with my phone not only happens when it is being charged through charger but also while connected to USB port on a PC. I had it replaced with a new one. They said it is a hardware issue but others say it only happens when they upgraded from 1.6 to 2.1 so it is probably a 2.1 bug.
Well, to be honest, I dunno.. I've upgreded to 2.1 right away, so I don't remember if this appeared on 1.6 as well :\ But I don't wanna run on 1.6 anyways, so this doesn't bother me really
I had a similar problem on my mini pro but ONLY when using a charger other than the SE one that came with the phone; fine with PC USB charging or from the SE charger but goes crazy with false touchscreen presses or the TS failing to respond at all on one occasion until I figured out it was the non-SE charger. I think the issue may be that when using a stand-alone USB charger, the SE version supplies much more current than a standard USB port; presumably, when using a port on a PC the driver SW adjusts the charging current to compensate but non-SE chargers may not supply sufficient voltage under the charging draw the mini pro wants.
yeah~ just go for a ORIGINAL charger, don't buy a cheap one, buy a better one! it's the charger problem
My work-around
Hello all,
I'm experiencing the same problem and might have some new insights. I have tried multiple chargers including the Sony Ericsson charger that came with the phone. These are my findings:
- SE charger (wall socket 2 USB) (5V, 850mA) - The problem occurs, however I'm able to navigate
- Cheap Ebay charger (wall socket 2 USB) (5V, 1000mA) - The problem occurs, can't even get passed the lock screen
- Cheap charger (complete charger, no seperate USB cable needed) (5V, 550mA) - No problems
- Charging via USB of laptops and desktops with the USB cable that came with the phone (5V, 500mA) - No problems
Needless to say that with 500mA the charging takes very long.
BUT...here comes the kicker (and my solution):
- HTC ORIGINAL AC EU WALL Charger TC E250 USB ADAPTER (Wall socket 2 USB) (5V, 1000mA) - Charges fast and no problems.
So, in my case it seems as if the problem occurs while charging above 550mA and probably only with cheap chargers, including the SE one. The original HTC charger works like a charm.
I also found out that the touch controller is right next to where the micro USB connection is located. (google "Sony Xperia X10 Mini Pro Teardown and Analysis", I can't post links here...)
Apparently, bad chargers interfere. Hope this helps.
i do use original SE charger and don't even have another but what Neliscornelis posted might be useful THANKS!
I use original SE charger and haven't any problem
I get this problem to.. What i have to do is hold the lock button until the power off screen comes then cancel.. Also I have another problem when in calls.. the screen blacks out every time i try to end the call!! Does aqnyone else have this?
touchscreen problems
hi! i have similar problems!
that problems occur when connecting phone to my pc with original SE cable.
also tried with another original usb->microUsb SE cable, and problem stays...
no matter what charger I use, i always have same problems with touchscreen.
also I tested it with original htc charger and everything is same again, touch screen is registering multiple taps!
so, for now i tested this situations, and problem is always occurring:
-when connecting phone to pc with original SE cable
-when charging via wall outlet (tested with 2 original sony ericsson chargers)
-with original htc charger
only exception, when everything is working fine is when i plug phone in my car (via car lighter->usb adapter)
any solution?
thanks
I can confirm this bug. Original charger 1.6 and 2.1 all the same. The phone seems to be registering random touch events without any physical input.
Also, the proximity sensor doesn't seem to be working while charging. Combined with the false touches, making calls with the phone on charger isn't something i'd recommend.. :\

I am experiencing this one too. I think it's the static from our skin.
I tried putting my finger in front of the screen like less than half inch above the surface (but not touching the screen), and it activates an icon. I can do it all over, so I know its not just a delay of the screen from a previous touch.
The notification bar above also goes like its going crazy or like flickering.
The touchscreen i think is plastic and not glass thats why it's prone to static.(not sure). but whatever that screen is made of, there's some sort of static going on.
Hi i think that the unresponsive screen is due to the fact that its actually oversensitive. i mean the screen is sometimes activated by the sides of the phone and the botton of the screen where the xperia logo is. I am wondering if there is a file that changes the screen sensibility? dont you know how to do it? rooting the phone or something?
Other idea im having is to dissasemble the phone and put something under the black plastic where the xperia logo is to reduce the sensibility of that area. any ideas?
I have record a video watch it to see what i mean with oversensitive. And yes this is a new out of the box xperia x10 mini

Unrelated effects. It isn't static, it is capacitance. These phones have a capacitive touchscreen and your body contributes to the electrostatic field that is part of basic capacitor physics so that it is possible to affect the field to register a touch by merely moving a finger close without actually touching. This is normal. The problem with random touches (when no finger is even near) and the charger problem is not normal.

Dont get me wrong when i ask you this, but what do you think how much your battery like to be charged with that charger? How much you think it will last?
When i charged mine with original SE charger (5V, 850mA) it takes me less than 2hours to fully charge it.
When i charged with PC USB it takes it about 4-6hours.
So, im sticking to charging mine with PC USB..

Really? Mine lasts 2 days with data traffic on, wi-fi, gSynh, gTalk and gMail always on (cause of my work).
Did you followed guides here on forum regarding a battery?
There is a guide of deleting batterystat.bin file in your phone (must be rooted)
batterystat.bin is file that Helps Android read your battery. Its not quite accurate, so, after every reflash/custom you should fully charge your battery and delete that file.
Process that i do after every reflash/restore/messing around.. I fully charge my battery via PC and leave it for ~30 more minutes. I delete mentioned file while my phone is connected via USB to PC, reboot phone and remove USB while it boots, that way, your android will see fully charged battery and pass that info in baterystat.bin, after that, im not connecting my phone until battery is fully depleted.. that way your baterystat.bin will have max and min values for battery. But, its only me, no one needs to follow this..
Also, i read that battery life can improve over time (until batterystat.bin hits the right values)..
Edit: Download Advanced Task Killer from market, it will help you kill unwanted tasks, thus saving your battery life.
Do you think that changing the digitizer will fix the issue?? Its like $20-$30 on ebay. And this phone its extreamely easy to open and change the digitizer in home!!
Or could this be a problem within the phone itself? i mean everything works except for the touchscreen!!

guess i just used the wrong term. but i guess you get my point
but it never happened to my iPhone, and iPhones have capacitive touchscreens too
Hello all,
I am facing a weird problem, ma P500's touch screen is not working properly when plugged in to the charger. The touch recognized by the sensor, is not at the exact point whr I touch. If I touch on clock, the notification bar gets pulled down and so on, this happens only when I plug it in to the charges, else it works flawlessly.... Has anyone else faced a similar prob???? Please help!
I had a similar problem and it was a bad charger. I replaced the aftermarket charger that I originally had with an OEM LG-branded USB charger and the problem went away. There are many posts online about this problem happening with all sorts of chargers, so it seems like something that can happen with chargers and you just need to get a different charger to fix the problem.
Neil,
Thanks a ton!!!! Minutes back i was suspectin da same, cuz da touch response was flawless whn i was charging thru USB.

Hi all,
I have an AT&T Samsung Galaxy S 2 (i777). It was rooted and running CM 10.1. A few months ago it started to have charging/USB port issues. Some of the symptoms:
-Sporadic charging (starting and stopping)
-Required USB jiggling to get it to start charging
-Sometimes wouldn't charge at all until it died, then would eventually charge while powered off
-Would not shutdown (only reboot, even if the battery was removed)
-Randomly started "car mode"
My initial thoughts on this were USB port issues. After doing some research on people with similar problems, I tried cleaning the port with alcohol, toothbrush, compressed air, etc. No avail.
Eventually the phone just stopped charging altogether. At this point, if I left it plugged in, it would sit in a continuous boot loop (boot, get to lock screen, realize it has no juice, shutdown, rinse, repeat). After a few days of attempting to charge and just having that happen, it went black and has never turned on since.
To try to solve that, I bought a new USB port flex cable on eBay and replaced it, assuming this would solve all my USB port issues. I tried to be as ESD safe as possible and also not break anything in the phone, but after replacing the board, it still wouldn't boot.
Next step- bought a new battery with an external charger to skip the USB port altogether and see if the battery was shot. Charged up the new battery, popped it in, nothing.
I'm at a total loss. If it started as a charging problem, I don't see how the problem could have been anywhere but the flex cable board or the battery. Does anyone have any ideas about what might be going wrong? I would REALLY appreciate some insight.
Thanks!
Maybe the repeated loops damage it

Did you ever find a solution? I'm in the no charge boot loop after letting it die last night.
I have not seen previous usb problems at all. I suspect that my battery got over-drained, but then I've got the same symptoms as you and you have a new battery. I can get it into recovery but t won't stay on in CWM for long enough to fix permissions, which is the only thing I've tried so far in CWM.
Thanks
If i was in your place i'd have taken it to the nearest Samsung Service center and let them fix it for me.
I think the fluctuation in power may have damaged your phone battery point from where it takes power from the battery and charge it.
Maybe it has damaged the motherboard.
We cannot say anything in this situation.
You should just take it to your nearest service center.
Best of Luck
OK, wiping Data fixed it.
Thanks for your reply. This problem just started this morning with no previous issues, doing the looping part of your problem that I quoted. so it's not a question of what I might have done.
But, for others encountering my part of it, here's what I've done and learned so far today.
As I looked into things elsewhere on the , it seemed to be a software problem. Luckily, I have another Galaxy (Exhibit) that's similar battery and I was able to put the charged battery from it into the SII. The SII booted and worked fine but did not charge. I put the SII battery into the Exhibit (sorta fits). It took a charge.
This confirmed to me that it's not the battery. It must be the phone perhaps USB port or more likely "firmware" since problem started abruptly after draining battery down.
I then wiped data on the SII from CWM/recovery and rebooted.
SII is now charging again. Stock battery is back in and working.
Time will tell if all is well, but here's what I think happened:
1) battery drained down to zero while unplugged
2) plugging in and starting up phone immediately threw something off in the battery stats at a low level...that kept it from charging even when turned off. Or rather threw it into a loop. Don't really understand this stuff, but may have to do with physical things that happen in a battery when the cells drop down way low and then the voltage feedback they give to charging circuit.
3) charging battery in another device (gingerbread, by the way) got the battery out of this, if battery had been a contributing factor,(or just a trigger) it was back over the hump.
4) wiping data fixed the charging, so I conclude it was a charging circuit data issue triggered by an ultra low battery.
Hope I'm over this problem and hope that it helps somebody else. If you run into this yourself with no previous USB or hardware issues, I'd suspect software before hardware. If I had only one battery and no way to charge it externally, I would suggest get one of those simple universal clip-on chargers to bring the battery back up and then go into CWM and wipe data.
UPDATE: It's stopped charging again. It's no longer looping since I got the battery charged up, but not right either. As soon as I plug it into a USB, it boots itself without powering on.
I guess that this is looking more like a physical USB issue now. Weird that there's been no previous sign of trouble before today.
UPDATE2: I cleaned USB port but no help. Then I bent the USB contacts towards the screen and it is charging now again. I'm ordering a replacement USB.
I should add that I'm running Shostock Jellybean, older (not current) version with it's associated Jeboo kernel. Don't know if it matters.
I wish I'd seen your post sooner.. I had exactly the same problems back in January. Took all the same steps you did. In the end, an 8$ USB flex cable from EBay solved the problem. I think you'll have luck with that:thumbup:

hey, I'm experiencing the same issue slightly different.
-Sporadic charging (starting and stopping)
-Randomly started "car mode"
-plugged in the charger while the device is switched off, it automatically turns the device on.
-If the cable still plugged in while the charger removed from the main current, it shows "Charging stopped. High voltage"
-From yesterday, it doesn't charge even. Only way to charge is, connect the charger first and then Restart the device.
Then only charging continuous.
Can anyone help to solve this? Is this a software issue?
Thanks!

Also, there was this issue early --> when I charge it from the laptop, the USB mode doesn't switch on. It just charge the phone only.
But now it's not even working like that.

hi, my s2 wont charge. It just shows up charging when plugged in but it doesnt charge at all. and it overheats too much while plugged in. What is that flex cable you said, is it the one that connects the charging port to the motherboard? were you the one opened and replaced it? thanks
Hi there,
After a few weird battery problems with my tf201 where it would only recharge at a drip-charge rate it finally came back to normal and started working again. Then the dock started acting up and wouldn't charge the tablet whist connected. After getting a new cable the problem still persisted so I am certain there's a real issue with the battery.
Now however the current issue is that it will only light up the screen for use whilst it's connected to the charger and power is flowing in! It's on full battery and will not show the screen after pressing the unlock button without the charger in. It literally flashes on every millisecond the chargers connected!
Any ideas of how I could fix this? Looks like i'll be sending it off to ASUS pretty soon unless somebody fancies buying it.

Were you ever able to fix this? I am having the EXACT same problem. I believe replacing the charging port might solve it.
Unfortunately not

Unfortunately not pal, I took it apart to try and replace the battery and ended up damaging it more.
I just ended up selling what I could for spare parts.
Good luck with yours dude.

I have a problem when my HTC one is not really charging. In several hours I got only 4%. I tested it with battery widget and it barely gets 10-100 mA when charging. Once screen is on, mA goes negative, even though phone is plugged in. Maybe I too need to put it face up...
________________________
Update:
It finally got fully charged with ~600 mA input. In my case it appears to be a faulty charger. Check your charger, test it with different wires, maybe it has bad connection? Just a speculation.
