hello,
I wonder if any one has this phenomenon. Only when device is connected on external power the screen freezes and hardly can scroll.
A bit annoying but if solution there that would be great.
Thanks
It's your charger. Mine works fine on stock AC charger, but if I were to use the AC/DC 2 in 1 charger on AC the capacitive screen stops responding (the same charger is fine when plugged into cars however).
Not unique to GS2 if you google "capacitive screen charger unresponsive", and no one really knows why.
May be USB cable Prob

Thanks for your reply.
I did find that with Samsung orginal charger there is no issue but if I do use an USB cable to charge from the stock I get the screen issue. The same USB cable while used on computer there is no ussue neither.
Just for info.

Does anybody charge their TyTN in car via a usb car charger. I use a usb car charger for different devices: Bluetooth headset, gps reciever...
I also used it to recharge my Blue Angel.
Unfortunately I can't charge the TyTN. Has anyone had the same issue?
The charger says that it can charge 1Ampere. The original home charger is also 1 Ampere, so I don't understand why it doesn't work.
Have tried it with two different usb car chargers and both have the same problem: It charges only if TyTN is turned off. When I switch it on then the red charging light turns off.

I had similar problems except I didn't need to swithc the pda. I saw the usb charge couldn't charge completly or it was very slow to charge if I had screen with light or TomTom running.
I solved using a diferent charger, that generates 220 volts. It has 140W and costs around 40 euro.
Do you have a link, a picture or a brand name to this product?

Same problem.
I was told by the dealer that it's a matter o cable (the pins in the cable)
the one sold with the device is fine just to sync and charge from pc, but can't charge through car adapter.
I'm bought a new cable (arriving next week): it's a double cable, one side for pc, other side for charging.
if it works, I'll post..
bye
I'm afraid to tell you that your new cable will not work. You were not well informed. I am sure that it is not a cable problem, but a charger problem. According to me the power output expressed in Amps (Ampere) is not strong enough even though it says that it's 1 Ampere as the mains charger. Those cheap chinese made chargers are not strong enough for the TyTN. That's why it charges when the TyTN is switched off but as soon as you switch it on, the power output from usb car charger is not enough.

mmhhh, I'll wait the new cable, hoping it works ;.)
the fact is that with original cable the car adapter doesn't charge even if the device is off..
same thing with a 220V usb adapter.
only the original kit seems to work..
I'll tell you in a few days
btw: both adapter are chinese ;-)
Nope, Lio is right on this one. The car charger simply doesn't supply enough juice to charge the TyTN. O2 Exec users have had this problem for ages.
I use the charger bought from the Orange shop for the spv c500. Works fine, if a little slowly.
There are strange things happening!
The USB cable should not enter in to the equation as USB is USB and the pins should be wired correctly.
Here is what I have found.
If charging in the car all is ok until the power is cut, then it only charges whilst off until the TYTN is soft reset. This looks to me like there is a software / powercontroller confilct. It is a little confusing but see the scenarios below;
Soft reset TYTN, leave it off. Plug in to cigarette charger, turn TYTN on/off all is fine.
Turn off TYTN and unplug, all is fine, plug back in (TYTN off) will still charge when TYTN on.
Turn TYTN on, unplug, will not charge whilst on anymore until soft reset but will charge whilst off.
This is the same if I turn the ignition to power the lightere socket.
However, another spanner in the works, if I pull out the charger even with the device off and re-insert it it stops charging until soft reset.
What seemd to work best was to do a soft reset whilst the unit is charging and powered on. After that I was able to unplug, plug in even when the unit was on, turn ignition off/on etc... It only reverted back to not charging when I removed the charger from the socket as it was charging.
These are my findings and I presume each charger will be different.
I presume whatever electronics are in the chargers also causes problems. I have tried 2 USB and one fully wired charger and it is the same with all. I know for a fact that at least 2 of them have overcharge circuitry built in but do not think the 3rd has, I also presume the TYTN also has so perhaps there is some conflict here also.
I do know that there are car chargers specifically for the TYTN so will try one of those and see if it solves the problem. (anyone tried one?)
Anyone with more ideas please let us know.

Thank you for this tip. Now I can recharge in car thanks to u! :lol: I tried it and it works.
Great Lio,
Glad it worked. When you get a chance, could you pull out the chrger from the lighter socket as it is charging and let me know if it then stops charging again. I just want to see if the same happens to you as it did to me. It will work again once you soft reset whilst plugged in.
Thanks.

I believe this trick should go to FAQ.
A week ago I visited a lot of shops trying many mains-to-USB charges to no avail. I already had one for MP3 player that didn't work too.
After reading your post, I connected the original charger and SRed. Now that another charger works!
Can't imagine what's the reason but it really works.

Same here.
Is this a bug in the software ?
I found this : http://www.expansys.com/product.asp?code=138248
I think it should work fine, I am not sure.
"I found this : http://www.expansys.com/product.asp?code=138248"
Could you contact them and ask about its power rating and whether it is susceptible to the problem/bug?
here I am again.
finally I got the new cable and... surprise... IT WORKS
I used it without soft resetting the device and it worked
I tryed soft resetting the device and it worked
But the biggest surprise of all is that after using the new cable, also the old one started working ..
i guess there must have been a software bug that has gone (hope forever) away.
For those interested, the new cable is a double one: one side is usb, other two sides are charge connector and hotsync connector.

have you got a web link for this one you now have?
friend of mine has apparently got a tytn, I'll pick up a 1.2A USB / Car adapter this weekend and see what happens, hopefully the extra .2A should enable the tytn / exec to charge normally in a car.
Having had an exec for a while I will agree that most 12v/USB adapters struggle with the exec, but hopefully this will make the difference, if it works I will post the details of the company selling them (they are listed for the PSP)
I haven't had this trouble. Just got my new MDA Vario II and I've used it with my old MDA compact mains charger and the car USB charger and it works with no problems.
Tried it with the Vario II on and off and have a charging light on both.
Has anyone else had this problem? I plug my Photon into a USB power adapter plugged into my car's cigarette lighter and the phone displays the message that the device is charging but the percent of charge continues to decline. I have changed USB adapters and USB cables but it still happens. If I use an AC adapter and the same USB cable the phone charges correctly.
Is it a software or hardware problem? I was unlocked and rooted using several of the current custom ROMs and the charging process in the car worked then. When I re-locked and went back to stock and re-rooted then this happened.
i am having the same issue as of yesterday. Did you ever find out what the issue was?
im guessing that the car was off and that it was a foreign car...
Numerous issue could actually cause the same symptoms, Apps/games in the background... failing alternator, failing cigarette lighter, failing car adapter...
car not running while its charging could also cause this issue depending on charge level of the battery and the volts of the battery...
What you'll need to do is eliminate the possibilities..
Try with the car on and the phone on...
try with the car on and the phone off...
try with a different adapter for the car...
try with a different usb cord...
try with a magnum 44 aimed at it...
Try with a different Car is also another good option.
Ditto.
I am having the same problem.....worked fine before I unlocked/rooted. Anyone else have a suggestion?
I have the same issue with the incar charger and using a computers usb port to charge my phone..(doesnt charge when under load ..ie-dowloading something)...i think that it is the charger being underpowered..example..
Stock a/c charger puts out 850mA
Most computer usb and standard car usb chargers only put out around 500mA
Sent from my MB855 using xda premium
Mine charges very slowly in the car. The other day, I plugged in at 32%. Drove 30 minutes to get home, and it had only reached 37%. Plugged in at home, and within 10 minutes had well over 50%, even though I was actively using it then.
This is on stock rooted, btw.
The stock drivers must use a very conservative power draw when plugged into a relatively low-output power source. By contrast, the power draw from a high-output AC adapter must be quite aggressive, because it charges more quickly than other phones I've used when plugged into AC.
It did turn out to be caused by the car charger being underpowered. I went to BestBuy and bought a "high capacity" charger and all is good!

Which specific car charger did you get? I'm having the same problem too!
The Photon needs at least 850mA charger to get charge currently. Otherwise it charge slowly or not charge at all.
Can anyone post a link to a specific charger that is working great for you and charging fast while in the car?
has any one who got charger working ? can anyone pls post the link to product
thanks in advance

Hi all
I have strange charging and USB issues with my Atrix.
when the phone is on it will not recognize the USB connection, no USB notification and will not charge ( PC or Wall). its seams that the usb port is completely dead!
when the phone is off, connecting the wall charger or the usb, green light on the phone and the phone will boot. still no charging.
in RSD light mode, the usb port is fine ! even I can flash.
to be more strange, using multimedia dock: the phone will charge as it should no mater the phone off or on !!
now I have stock ROM 2.3.4, I have tried different Chargers and USB cables but nothing changed.
I have searched the forum for similar issue but didn't found one. so if any one have the same issues ....... you are not alone
thanks
i've had weird results with chargers that were weaker than the stock charger that came with the device. i'd say as a good rule of thumb it needs to be able to provide at least 0.85 - 1.0 amps.
I have two motorola stock chargers, one is its original charger and the second is defy's charger. both work fine on the defy but not on the Atrix..
I think you are right. may be the power is the key of the mystery. because the multimedia dock has its own power supply which provides 1.5 Amp. so may be there is a malfunction in the phone hardware (charging ckt.) causing the phone to draw more than rated power from the charger which the stock charger cannot provide!
I have the same issue either! Exactly the same.
It happened like few days ago but I didnt aware that until my battery runs out
I just got my Tab p7500 and i have a problem. When i connects it to the charger it gives me MTP mode and charges veeeeeeery slowly as if it's connected to a usb.
Anyone knows what is this problem ?
Are you using original charger or some compatible, f.e. from your mobile. The original gives higher output power.
Does it actually show the connected as MTP notification? If not, make sure the charger is plugged in with the black wall adapter that came with it, since that gives it the full (10W i think) of power. If you plug it into one of those generic usb bars(like the Belkin mini surge protector), you will get only the power output meant for mobile devices and will charge very slowly.
i have the same problem
It takes me approximately 4 hour from zero to 100% with the original charger...
i just recently had the same problem.
buying a new adapter solved the problem. it seems that samsung's chargers aren't that good of a quality. (my sgs2's is working, but the outer part of the cable started to split so i had to fix it with some shrink tube...)
Hi,
my Samsung Galaxy S3 (i9300) recently started to be very hard to get it even to charge a little...sometimes I was forced to charge the battery manually by taping +5V and GND cables to the battery because the phone would just refuse to charge.
I suspected that the micro USB socket in phone is corrupted, because I've sometimes tried 6 different USB cables and none of them even worked for a few seconds. Then after struggling with it, it SOMETIMES started working.
I've also tried 5 different chargers (original 1A HTC Charger, 2A Samsung charger, 1A iPhone chargers, some different 2A charger i just bought because i thought it may finally start working)
And so yeah, I've bought a new charger with new usb cable with 2A at output, hoping it will work. But guess what? It didn't even charge the phone for a seconds, it charges other phones, my old HTC phone, my sisters Galaxy S4, but not my S3...it is not the cables fault (im 100% sure) because i have it connected and charging to my old HTC charger (1A at output) and i just plug the cable to the new 2A Charger and it is not working anymore...
The weirdest thing is that most of these chargers (Except the new one) were all working with the phone, but stopped after some time, like my old charger stopped working so I tried another one - it was working, but after trying it again or few times later it just stopped...
Any ideas? The battery is holding power long enough I think, so I dont think it is corrupted, what else could cause this?
Edit
Suddenly, after my phone dropped down to 7% and I had problems with connecting it to the original HTC charger (1A at output) i tried the new 2A charger which never worked with this phone, and BAM, it is working now and charging very well.
However, what started happening now is that when im charging the phone (through USB cable) it keeps spamming "Docking station connected" and going into docking mode, which is very annoying. I guess there is some problem with the socket? :/

I can see your assumption, but have you ever tried another battery ? Just for checking, to make sure...
