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
Anyone noticed this problem? I'm using aftermarket charger (copy of iPhone charger from DX), and after 3 hours of charging phone started behaving strange. While typing, it inserted random letters. The faster I tried to type, the more of random keypresses. Scrolling is almost impossible, because almost immediatelly instead of moving content phone registers touch on screen and tries to behave like that. Only when i put my whole finger with medium pressure and move slowly, I'm able to scroll. Else it just randomly "clicks" on screen.
First I thought that it is some kind of trojan/virus, tested with ESET and no change, restarted phone multiple times, no change. Strange is, that phone was charging since morning and it worked well. Maybe battery is now fully charged and it started behaving like this. After removing it form charger, it starts working correctly again in 5-10s. Tried even different charger from my colleague, same behavior (but it is also OEM without brand name). Tried also reversing charger in outlet, no change. Different outlet no change.
At home I charge with old iPad charger with 2m cable and it never happened...
Assume that I have to get some better charger (original from phone doesnt fit our EU plugs), but still i'm bit afraid that even new one could behave this way.
Yes I had that problem with several phones from different manufacturers: Atrix, Galaxy S ll and MyTouch4G. It is the 3 party charger that can mess things up. In case of my GSll it was even with the original charger.

Sounds like a noisy charger that is seriously screwing up the touch sensing. Use a high quality charger from Samsung/HTC/Apple, and make sure it is a genuine one.
Few days ago my Samsung Galaxy S II I9100 stopped charging properly. If I connected the micro-USB charger, the phone just didn't charge. I tried with another charger, but this did not help. As a next step, I cleaned the micro-USB socket with compressed air and contacts with isopropyl alcohol, but still nothing. If I turned the phone off and connected the charger, instead of charging, the phone started to boot up. Often after the bootup the phone charged for few minutes. According to Battery Widget utility, the battery itself was healthy. As a next step, I made a factory reset, but this did not help. Installing the latest firmware didn't help either. Once those charging problems started, I also noticed that scrolling through messages or using the keyboard was bit disrupted and I often had to press a on-screen keyboard multiple times to print a letter. Finally I took the phone apart to inspect any visual faults, but there were none. All the connectors were properly connected and there were at least no visual signs of malfunction of electronics.
Has anyone seen such behavior? Is it possible that faulty charging module causes such behavior? I would doubt that as this charging module seems to be a fairly simple hardware detail and it's hard to see that this could cause a phone to behave like I described above
@m4rtin86 So far as i can read it, it is the Battery which doesnt want to get always charged or the charging module like you said. Maybe you can borrow a friend's s2 to see or his battery charges in your phone. If it isnt the charger/usb cable then its battery/charging module.

I replaced the charging-module and phone started to charge again. However, I'm bit puzzled how such seemingly simple component could cause such behavior? All it seems to have are just micro-usb jack, microphone, few contacts for speaker, connector for antenna and some electronic components like resistors, SMD capacitors and that seems to be pretty much all. How could such a simple component cause phone to behave in such way?
@m4rtin86 I have no clue why that component behaved in such way, but weird things happen to stuff sometimes and nobody knows why and how it could happen. Maybe something was loose a bit and didn't made good contact anymore just sometimes maybe.
Its good to hear that your phone is charging normally again I hope it stays like that for the next 2 years atleast.
hello,
i bought pretty beat up i9100 (it wasnt charging, i fixed it by replacing usb port in it). phone works now, but the battery acts weird, it discharges way too fast and charges way too slow, sometimes its discharging even if its connected to charger and it skips percentages. it doesnt generate too much heat. battery calibrations, apps that monitor battery usage and other crap didnt help and im running fresh and clean cm12 on it, and there is yellow triangle in boot animation (that might indicate some trouble). according to some internet tutorials i found i9100 is susceptible to short circuits and they indicate that soldering some ic on main board might fix it, but before i do something im probably going to regret i'd like to ask here how could i prove its really shorted and that the problem doesnt lie somewhere else. according to previous owner battery should be okay and phone was behaving the same even with completely new battery.
when i insert charger phone doesnt recognize its charging for about 10 secs and when i disconnect charger phone keeps showing its still charging for about a minute after disconnecting it.
many thanks for any help and/or suggestions.
The Home button on my P9000 has always been somewhat unresponsive when my phone is charging. When I unplug it, it is fine, and as it charges so fast, I rarely use it plugged in. So it's not something I think about very often, but it is annoying when I do need to, and half the time I just unplug it, do what I need to do and then plug it back in again.
I assume it is EMI being caused by charging that is affecting the Home button capacitance, especially condidering they are on top of each other.
Is this a design flaw that all of you face, or is there a shielding problem with my phone?
It is just bugging me right now (despite having dealt with it for almost a year now), so I thought I would ask your opinion.
I have no idea what the issue maybe, but mines always kind of done it but as I dont really use it while charging it hasn't bothered me. If I do need to use the phone I just unplug it. But yes, mine does the same thing too
For me its allways been working well, butbthen again, i dontnuse it very much when its charging, just to see the hours or some simple apps
