My SGS2 turns on once usb cable is plugged in. Please help

This behavior started last night after activating Monitor power usage in the battery settings section. Deactivating it didnt help. I tried removing battery and that has not worked either. Im down to going back to stock or maybe even reinstalling an earlier Miui backup I have to see if that works first. Any advice would be appeciated, thanks.

And what's the problem with the screen turning on when you connect usb? It's normal and it also happens in stock roms.

I don't know if it's the same thing, but something similar happened to me too. What i did was just cleaning the micro-usb connector on the bottom of the phone. This never happened to me anymore.

you just created a connection between 2 pins in the connector, the same as when you plug in the charger, its normal behaviour, dont worry about it.

Go into Application settings (or Development, can't remember where it is on MIUI) and turn off "keep screen awake". It's for developers who don't want the phone to sleep while debugging.

Ok I think I finally found what was causing this. It only happens when USB debugging is turned off. When I turn it back on Im able to charge without the phone automatically booting back up. Im not sure if this is a bug. Should it be behaving like this?

Verrified that and its turned off. Turning debugging mode off causes my issue though. I find that kinda wierd.

USB debugging mode has always been weird on MIUI - on my GS2 it doesn't recognise that the USB cable has been disconnected until you reboot the phone.

Thanks for the tip, I've been wondering the same thing myself. This was a pain when I was trying to charge my phone at work with it off. Thanks.
PS: I really wish people would properly read the post before answering with the standard "it's normal, don't worry about it" etc. See it far too often.

Havnt been able to find a fix so far. What I do is I keep debugging mode off for everyday use and just turn it on when I need to recharge the phone over night. That way the phone stays off.

my iconia wont charge :(

When i connect the charger to my iconia tab will glow a orange ligth but after a while it starts bliking a red(maybe pink) ligth :crying::crying::crying:
I tested my charger and it seems to work fine
Is it a hardware or a software issue?
P.S (sorry for my english):angel:

When you say you tested your charger, did you use a multi purpose voltmeter to make sure it puts out the correct voltage and amps?
Also, are you running a custom rom or factory stock?
If you have cwm installed you can wipe battery stats and see if it helps.
If not, and you are on ics you might try an ec flash through cwm.
Other than that, you probably have either a bad internal voltage regulator, unlikely, or a bad battery.
You can usually find battery replacements on the net. Just pop the back off and get the part number.
Or, you can send it to acer repair for warranty work.

If you want to eliminate software or hardware from the equation just shutdown the tab and then connect the charger. If it charges then you know that the cause is in software. If it doesn't then it's the hardware at fault.

Do not boot the tablet. Just shut it down fully, connect charger and leave it for some time. Just observe the power button LED. It should be red while charging.

I have the same issue. Tried a million different ROMs and that didn't seem to solve the problem. The Orange/Red light comes on when the charger is plugged in but no matter how long I leave it on there the battery will say 12% when I get into Recovery.

Also, it may be good to mention that I can't mount the sd in recovery either, if this isn't a power hardware issue it may be related to that? I got the tab to boot but only the navigation bar shows and the top left corner says android system. Won't move past that.

This is in fact a charger problem; was having it I'm pretty sure its caused by your charger supplying the wrong amperage or voltage mine was doing it after it had been shorting out by the plug in. I took it apart resoldered all the connections put new wire in it and it worked like brand new never had had it since i would say do the same if you have the experience or know how if you don't they go on eBay for pretty cheap just make sure you don't get a fake one
Good luck

Placing n4 on charging orb doesn't play sound and doesn't turn on screen

When I place my n4 onto the orb, the screen does not light up and no sound is played as expected on 4.2.2
Because of the screen not coming on, daydream mode also doesn't turn on after the set time.
The expected behavior I have seen on a friend's n4 when they put it on their orb is for there to be a noise then the screen comes on. If you leave it on the orb then it goes into daydream mode after the screen timeout.
Anyone else have an issue where it doesn't do this or know of a fix?

Do you have a case on your phone? On larger cases, the distance between the phone and the charger is too much for it to work.

No case. Also, I forgot to mention that the phone does charge just fine on the orb. It just doesn't make the sound and turn on the display to eventually allow daydream to turn on.

Odd. I'm pretty sure that 4.2.2 update turned off the sound if the phone's charge is >90% or something...
I'm assuming you have daydream set up properly too? There are a few different options for when it should turn on.

Same behavior if battery is below 90%. I have daydream set to "either" but same issue is I set to charge or even dock .
Anyone else seeing this or just me? I may wipe the device to see if that helps but really don't want to.

yup, same thing happens to me. running 4.2.2
so I have two QI chargers - one is the LG WCP 700 and that one will light up the screen just like its plugged into the wall
the Orb charges for me just as you described. that tells me for sure that the phone recognizes this as something different
---------- Post added at 09:31 PM ---------- Previous post was at 09:30 PM ----------
actually this dock isn't perfect for me. if i don't put it on right, it will alternate between charging and not charging every 2 seconds, and this will actually light the screen up. doesn't happen often, but its really annoying when it does. fixes if you move it a bit.

[Q] Nexus 10 wont turn on.

I placed my nexus 10 on charging yesterday, and after a while (2-4 hours later) when i came back, i found the device to be turned off, I tried the power button in all the combination with volume buttons, but still no luck (even held the power button for 3mins) I searched online, and couldnt find any help on other forums. Some said to keep it on charging overnight and then try powering it up. But still no luck.
I dont get any notification when i connect it to charger, although when i press the power button while connected the screen lights up, and battery charging sign shows up.
Any help would be greatly appreciated.

So you cannot even get to the recovery?
You ether over charged it (very unlikely to happen) or you have a faulty N10.

No, can't even get to recovery. But i have been using the device for over two months now, nothing like this ever happened. What about the charging sign when i press the power button. It might be some kind of a sleep mode or something, no?

Could be a bootloader corruption, software issue, hardware issue or some part of the hardware "thinks" that it is still on when it is not causing it to not switch on.
Have you noticed any issues before it just came off like extreme overheating?

Well, yes the tablet was getting overheated after a long session of hd videos, or games, but that use to happen all the times.

I believe this is normally called a "Sleep of Death" or sometimes "screen off death". Hold power + vol up + vol down at the same time for 5 seconds and you should boot into fastboot. From there hit the power button to turn the tablet on. Then go about finding a better ROM/kernel combo that doesnt give you this problem.

You just need to press power and volume down to enter the bootloader.

Try press and holding the power button for around 10 seconds and then try powering it up again.

Are you using the charger/cable that came with your device?

Its working.
Weird how it was taking any input from the power button though. I kept the tablet on charging over night and i tried turning it on in the morning and it worked.
Thank you all.

I've had my Nexus 10 for less than a week, and this morning I encountered this problem. I was working on setting up syncing through an app called FolderSync and SugarSync. Syncing of one of the folders seemed to go into a loop. The device locked up completely a couple times. I got the process running again and left it running while I went for a workout. When I came back no way could I get it turned on.
I had tried all the things suggested here before checking here for help. I'll try your "solution" of leaving the device on charge overnight. If I can't get it going tomorrow morning I'll return it to Staples, where I bought it.
I have an iPad and have never encountered anything even close to these problems. Bought the Nexus 10 specifically to run the Vim Touch app for Android. The only Vim app for the iPad is horribly crippled.
Sounds like this thread pretty much exhausted the possibilities by the time epicbearman discovered his "solution," but if by chance anyone has any further suggestions I would be grateful.
Thanks,
Eric Weir

I had the exact problem as the OP and none of my chargers worked. I then googled and found someone that said to try to charge via their PC USB instead of the wall charger. I left it plugged into the USB for a couple of hours and the charge went to 4% ( so it must have been very dead ) and all is well.

I charged it via the usb charger, and connected it to my pc overnight. Try doing that.

Take off the back and disconnect the battery and reconnect it

Thanks. If I'd gotten this in time, I suspect it would've worked. But when I couldn't get it started after trying everything else and leaving it on charge overnight, I returned it to Staples.
Will order a Nexus 7 from Google. If I can get Vim Touch running successfully---my reason for wanting an Android tablet---and I find the screen to small for heavy writing---I want to get by with a soft keyboard---I'll order another 10 and give the 7 to my daughter.
Thanks again,

[Q] Samsung Galaxy S4 SGH-I337 Hard Bricked? Help!

Hey everyone,
Problem:
Last night I was using my phone and it was on around 50% battery. I put it in my pocket and a few minutes later when i checked it, it appeared to be dead. It would not turn on when i tried to hold in the power button. I rooted my phone over a year ago and haven't updated it in a long time. It seems to have bricked out of the blue and it wont turn on.
Attempt to troubleshoot:
I tried removing the battery and putting it back in. When i do this the Samsung logo briefly appears with the normal unlocked screen. After about 2-3 seconds I notice a tiny glitch across the screen and then it goes black and there is nothing. I put my friends battery from his S4 in my phone and the same exact thing happens.
I also called AT&T and my warranty expired for this phone a few weeks ago. Does anyone have any suggestions on how to fix this?
Thanks,
-Alex

Does it do the same thing if you try to boot it into Odin mode? Meaning power plus the volume button.

Yeah I tried doing that as well. It only works for about a second. When I remove and reinsert the battery I have about a three second window before I get the black screen again. I removed the battery and right when I put it in I held the volume up, home, and then power keys. I see the screen start to change a split second before it goes back to black.

Does anyone know what could be causing this or what my options are? I am just over the one year warranty so i can not return the phone. I would like to troubleshoot it if possible, but I'm not quite sure where to start since I can't turn the phone on. I am leaving for vacation tomorrow night and I really need to have a phone. I have been trying to troubleshoot it since yesterday and I have had no luck.

Did you plug it in to AC and see if it runs--try that without battery also--

I assume by AC you mean an alternating current (standard) outlet? I plugged it into the wall charger with and without the battery and it did not turn on.

Okay. Is there anywhere I can do to diagnose the hardware or I could take my phone to get it fixed and diagnosed? This is my first time having a phone stop working so I am not sure what to do since my warranty just expired last month.

One last thought before I suggest giving up. Is it possible the phone IS turning on (and staying on) but the screen is just not remaining on? Troubleshoot by turning on the phone until you briefly see the screen, then give it time to finish booting (if it really is on), then plug into PC to see if it is recognized by the computer? If so, then it's a screen issue.
Or, could it be the power button is wonky and is turning off the unit right after turn on?
I'm perplexed....

If there is a CPR (Cell Phone Repair) near you, that would be my recommendation.

Neither my desktop nor my laptop can detect the phone. The only time the phone turns on is when i take out the battery and put it back in. It comes on for like 2-3 seconds with the samsung logo and then shuts off. I did that while it was connected to my computer and the computer didn't recognize it.
How could I determine if the issue is the power button before taking it to a CPR?

Not sure about access to button with back off or how to take apart. But, you could try to depress button and try to spray some electronic cleaner in it with the nozzle tube provided. Radio Shack has it if Best Buy doesn't. I doubt if that will work though. But, the spray comes in handy for me on occasion.

I took off the cover, and then removed the screws to take off the back of the phone. I held the power button from the inside of the phone and it still did not turn on. I used my friends battery that was at 80% charge to test it so it isn't the battery. I found this tutorial online for removing the power button which could solve the problem (assuming it is the power button) but i'm not sure if it is the power switch. Also the tutorial is for the S3 and not the S4. Not sure if I should attempt this or if there is anything else I should try.

I'd wait a bit and see if anyone that has actually replaced one chimes in. You could in meantime try the spray. Make sure it is electronics spray so it won't damage or gum up anything--like you said it may not even be the buttton--
good luck

At this point my thought is the button isn't the issue. The button itself seems to be working based on your description.
I'd say Cell Phone Repair or a similar place is your best shot. Good luck. Let us know how it works out!
