[Q] No Service while charging - Galaxy S II Q&A, Help & Troubleshooting

I have a strange problem with my SG2.
If i plug my SG2 on the charger, the service drops out so i can't call or use other network functions. This problem occurs only when i charge from the wall charger. I need to reboot the phone and remove the charger to get the signal back. When I charge from the USB port on my notebook the service doesnt drops out. This problem occurs since i got my SG2. I have already updated to 2.3.6 but the problem still exists.
Can you guys help me?

95% certain you have a defective unit - Return it to 100% stock, and if the problem still occurs, execute a warranty exchange.

hmm Ok, thank you

I do have the same problem with my Galaxy S2 i9100 running the latest nightly of Cyanogenmod 10. Quite frequently, the connection drops while charging. Usually, the signal returns after unplugging the charger.
Could anybody please confirm that this is a hardware issue and not a software problem? I'd be happy to hear reports from people who had the same problem and solved it somehow.
Thank you very much in advance!

For the records: I solved this issue by going back to a stock rom (Samsung). Seems to be a software problem.

Galaxy S2 don't turn off but reboot!help!

hello...i hope that someone can help me....when i try to turn off the device,it shut down and after few seconds reboot?why?
also simetime the phone don't turn on and on screen i see a green battery with a thermo....someon can help me?
Did you find the answer to this? i am sending my SGS2 back for replacement. i have the same errors plus the following.
Phone selects speaker rather than earpiece as default for incoming/outgoing calls
Phone on ocasions randomly starts Kies and Voice commands even if there is no physical contact with the phone
sometimes the phone defaults back to a launcher i have never seen before (it is not touchwiz) and i have no idea how to launch it without it doing it automatically.
The faults you mentioned can be bypassed with a battery pull but they are annoying, I didn't have these problems until i upgraded my firmware through Kies to KE7.
I have an O2 branded device.

Exactly the same to me
How do you flash congnition? just over the stock rom with odin?
did you flash modem?
Absolutely same here, since coming from CM7 to VillainRom.
Never had that before.
I´m waiting and watching it and your results!
Thanks for this thread.
That's why I don't root the phone..it works fine.

This has nothing to do with root access.
I cannot believe that any problem related just because you have access to your system.
Back to topic, flashed back to cm but problem persists.
It's getting really bad near to flashing stock and bring it back to change device if someone knows what it is could be helpful.
I also have this problem. I think it has something to do with the usb port.
Because sometimes it just scans for media, or it thinks it is charging. Really weird! Then i just put in the charger and it stops for a while. Turning off will just reboot the device. And removing battery and plugging it back it also just reboots the phone.
I hope it is not hardware related...
I was looking for help for a problem I have but this seems to cover most of the problems I'm having.
Mine has recently started going into a strange mode after shutting it down. I get the battery charging symbol alternating with the "battery overheating" symbol.
The only way to stop it is to remove the battery for at least a couple of hours (if you put it straight back in it automaticly starts up and goes back to flashing the battery warnings) or pressing Power, Vol+ and Home and choosing Reboot.
I have also noticed its very slow to respond to plugging the charger in or out. It doesn't always wake-up and bleep when the charger is put in and it stays showing its charging for some time after the charger has been removed.
I was told that the charger should be removed as soon as charging is compleated but surely overnight is the only time we have available to charge these phones!
Depending on the custom rom or kernel you are using, it might not support off mode charging.
To avoid having a "problem" with charging the phone in off mode, some developers decided to make the phone boot up when the phone is been charged when the phone is off.
Going back to an official stock ROM fixes this problem.

As for Cyanogen, since built 23, you can charge the phone when it is in the "off" state. Please wipe out your userdata partition before flashing. Do not restore from a previous backup.
I fixed my reboot problem (rebooting instead of turning off) by letting the battery drain all the way so it couldn't boot anymore. Tried turning it on to see if it really doesn't go on anymore. After that I plugged in the charger and I got the charging-symbol and it did not turn on so I kept it charging overnight while turned off and in the morning it was finished and turned it on.
I also cleaned the usb-port on the phone with a toothpick. It had alot of dust stuck in it which I couldn't see. After that no more problems...for now. They haven't returned for 2 days now.

What kernel and rom are you using? I have not seen the battery overheating symbol on the sgs2.
No, there is no need to remove the phone from charger, when the phone gets to what is considered full, the battery will stop charging by itself.
Are you using the original samsung charger that came with the phone, or are you using a after market charger? Most of these USB chargers do not send a signal on the data lines. When using these chargers, the phone becomes laggy and unresponsive, there is also a delay to register anything on the touch screen. Stay away from these chargers.
For lithium batteries just charge it whenever you feel like it. Lithium batteries have a few thousand deep charge cycles, meaning if you use up all the power, then charge it,you use 1 deep charge cycle. However, if you use the micro cycles for charging, you can charge the batteries a few million times. Leaving the battery on empty for too long will damage the lithium battery.
Can any one confirm if this is a hardware or software issue as i now have the problem when i try and switch the phone off it will just reboot?
The Same issue occurs in my sgs2
hi everybody,
i just got my sgs2 ten days ago
everything seems good at first
then i realized screen standby lock lag problem, there exist a lag between 1 second to 2.5 seconds.
i ignore that due to it cannot be named as a problem, it seems like a bad characteristic
then yesterday , i have faced with another problem
after i have docked the phone to the original vehicle dock kit,
phone cannot be closed via power button , i hold it 1.5 seconds then chose turn off among list, phone looks like to be turned off then after a little while it just vibrates and reboots. That is phone cannot be turned off, it s somehow turn itself on again.
Whats the reason of this problem ?
In another forum one faced with the same problem said that it turned out to be normal when the battery is erased but the problem is occured again after docking.
micro usb connector
I droped my phone in the water, got it alive again, but with all the error(overheat battery symbol, no stable usb connection, reboot when i power off, 100% charged not going away) replaced the micro usb connector with a new one.
Some problems are gone but i still can't connect to pc (kies, debug etc), poweroff problem still happen sometime.
Conclusion: It is not only the usb part of the phone that are causing this problem.
But I do belive its a hardware problem.
Have you phone maybe got to much to drink too..
usb port???
I've recently been experiencing the same problem
When I turned off my phone it switched on again!
And removing battery and plugging it back it also just reboots the phone.
Sometimes the USB connector and charger are confused
Do solved the problem by changing the USB port?
plz help me
Thank you in advance for helping me
This is definately a hardware issue. Clean the usb connector, failing that it will need replacing

[Q] Galaxy S3 charging problem?

So i bought my SGS3 (marble white) a few days ago and it was working perfectly fine. A few days ago my phone suddenly stopped charging. I rebooted the phone and it was charging again. Last night it again stopped charging. I again rebooted but this time it did not fix the problem.
I know that the charging port of the phone is not damaged as phone works perfectly fine when connected to a pc via usb cable and charges.
And i have never ever plugged in a non-genuine accessory to its micro usb port. Not even a dock!
Anyone with a similar problem or cure?
edit: software update fixed it in my case.

I will not say I have a cure, but I am facing the same problem, sometimes I have to reboot twice for it to start charging.
Guru's kindly look into the issue and help us, this happens in both the cases, while charging for adapter or while charging from USB.

Well not exactly, it does not happen when i plug the phone into a usb port.
It happens with the charger but, now my phone is not just recognizing the charger. I have rebooted twice, thrice but still the same problem.
I'm having a similar problem,
Charging when -
phone on
power save on - WIFI/data and most other things are off
charges 2% per hr with official charger (wall socket)
Charging when -
phone OFF!
40% per hr with official charger (wall socket)
Haven't really tried the PC USB charging yet,
But i have noticed that my battery info page says the phones been on battery for
2 days 22hrs, Very strange as i have charged and attempted to charge the phone more than 10 times in the past 24hrs.
Anyone also noticed the on battery time to be wrong?
i got this problem yesterday too , restart then its ok , weird ...
before reboot the battery icon shows charging icon but its not charging at all
does charging a battery run a software too ?
why you guys not reporting the issue in samsung mobile showroom from where you bought the mobile and take a use of your warranty card?

My mobile is no more in warranty as I have rooted my phone, will have to come back to stock rom for me to claim warranty, that's why I am waiting for someone to provide solution before I return back to stock rom for warranty claim.
Sounds like it's an issue with the charger, rather than the phone.

I thought it was best to ask here before i contact orange to report the problem, as i really didn't want to send the phone back to them if its something i could have fixed
I'm doing a factory reset and if it still has charging problems i will call orange today.
I'm facing the same problem. It started about 2 weeks ago.
I tried different chargers but no hope. the only way to charge it is via a usb port.
I had this problem once on the first day I got my phone. Worked fine though with an iphone charger with the samsung usb cable. Have any of you guys tried that?

I thanked your post accidentally while trying to quote you
The batterystats.bin file only resets itself after a full charge to 100%. That's the file that's responsible for showing all the battery usage info. So if you just keep topping up your phone without letting it charge to 100%, the battery statistics will be from the last full charge. If you see the graph you'll see it rises everytime you charge and then falls when you take it off charge. It cumulatively shows the amount of time you've used the phone on battery since the last full charge, regardless of how much you charge it in between. When you let it charge fully to 100% and unplug it, the battery stats file will be reset and give you a correct reading.

I'm having a similar issue, only difference to what you guys are having is that my SIII start charging via the normal charger if its been in USB for a bit, like 2-5 min. I tried the rebooting, nothing. it only charges through USB 1st, then it will work via the stock charger, I've tested it on another charger aswell, and the samsung car charger.
I really hope there is a quick fix, becuase I dont want to send it in for repairs, as cellphone providers in SA arent the best.
I had a similar problem with my gtab 2 10.1 but the wall charger is to blame

Galaxy S II power issues

Hi i have a Galaxy S2 with some strange issues attached .Firstly upon leaving overnight on a full charge it shows 100% charged but when unplugged from charger it instantaneously drops to critical and dies minutes later. Also the USB will not charge or connect to kies or register as a drive since the battery issue started . I have bough replacement batteries incase of an overcoooked original and same thing on all three.
The phone is on orange and is running a stock rom gingerbread 2.3.3 and is unrooted never been messed with or flashed and im the only owner .
Could this be a potential board fault ?or could it have in some way faultered on the firmware somehow with an easy fix
cheers in advance guys ..

First it sounds like a battery issue.
But if you checked with different batteries and with all you have these issues, it really seems to be a hardware issue in the phone ... maybe the battery stats chip, or the controller for charging (from power and USB plug).
If you are still on warranty, go to the store/service center and ask for a repair or replacement.
Good luck !
You can also try to clean phone battery connectors.
Best with izopropanol.

S2 thinks it is rechargin when it is not

Hi,
Yesterday when I took the phone off the charger normally, it started to indicate that it is being recharged, and a couple of seconds after it announces that it will no longer be charged and this same cycle continues and continues playing the annoying sound / message. I tried to fix it by removing the battery, but it did not help at all. I also tried to connect the phone to Kies but when Kies recognize it, the program crashes ...
So could someone please help me with this?

Did you try to blow some air in the usb port? As it may contain some dust that is leading your phone to notify you as if it is being charged...

Hey,
I have been actually been having the same problem, it could:
1. bad charging brick
2. battery issue
3. kernel issue - i dont think its this one any more because i am still getting it on the stock leaked firmware.
4. usb charging board
i have tried flashing different roms / kernels and doesnt seem to be a cache / file issue since it happening before the phone boots. (charging screen)
if possible try another s2's battery in your phone... power off the phone and see if it auto starts or goes into charging screen. I have a spare battery and i dont seem to get the issue on that one. (still testing)
I also noticed i really only get the issue when i leave the phone charging for the night then wakeup. pull the charging cable and the phone doesn't register the disconnect and says its still charging. if i connect the usb to a laptop and connect and disconnect, it registers instantly.
i have looked for bent pins / dust.. depending on the better testing goes it may be the charging board that could be the issue.
good luck

I agree with you about the usb port problem. I also had a problem with the usb port, the battery icon was blinking all the time and the phone had a huge battery drain issue. All I could do is returning to stock, unrooting and bringing the phone to service center for repair.

A116 Charging issue

For past few days, I'm facing this strange problem that the phone doesn't charge beyond a particular limit, and sometimes at all. When I plug in the charger, it displays 'Charging' but the battery level doesn't go up. I tried few things to understand where's the problem:
1.) I changed the charger and used the other ones (700mA, 500mA, USB charging with PC) and they worked well for a while, although slow charging, but afterwards the issue re-appeared and phone stopped charging even by them.
2.) I changed the battery, thinking it's a battery issue. The one that I got from a friend charged perfectly well with my own MMX charger for the first time, but now it's giving the same issue again and not charging beyond a particular level, say 40%, which will eventually come down and it won't charge at all.
I'm confused as what kind of problem it might be - hardware issue with the charging socket, charger/USB cable issue, or a firmware issue? Has anyone faced this problem till now wherein the their phone doesn't charge, even though it shows 'charging'? Please share what did you do to resolve it. I'm currently located at a remote place and cannot visit a service center.
how old is your device? if it's more than 9 months you might have to replace your battery. you could find it on ebay.
