Hi, I'm not sure how to start this, sorry..
My LG G5 has a problem where every time I plug in a OTG cable, a notification comes up that says power supply.. When I tap on the notification it give the options like charging only, power supply, MTP etc..
If I tap on MTP, the notification will go away, then will pop up again POWER SUPPLY. It is very annoying.
Not sure how to fix it. Any help is appreciated! Thank you!
Maybe the otg is lose thaty why its fluctuating try again by placing the phone on any surface like bed or table plug the cable and try not to move the phone and cable, this is what i do when i connect my phone to my computer if the phone is in my hands then i face the same problem so i follow this method i mentioned

Ok, so i keep getting this problem with my hd2, i tried flashing different radios & roms but no help.
its hard explaining the problem so here it is what happens:
sometimes the phone dont sleep, if i press the power button it just goes to lock, but the screen wont go off, while dis happens when i try changing the brightness, the "on battery brightness" dont change the brightness, but the "on external power brightness" changes the brightness, but the phone is not connected to anything.
when i finally connect my hd2 to my laptop or to charge and take da cable out den its perfect, it works normally
please help
the phone thinks it is connected to an external power source. similar sounding to the "stuck in car kit mode" bug. probably a faulty usb port.
had to send mine back for a new mainboard.
any other symptoms? loudspeaker auto activating when you make/take a call? phone pad screen auto rotating?
youusing the original cable?

No the loudspeaker don't turn on automatically, no rotation problems and yes im using the original cable.
I have a really weird problem. My computer won't recognize my SGS2 is connected to the computer at all. Meaning no notification sound, no device change in device manager, nor any prompt to install a new driver. I've tried in both MTP and Mass Storage. What's even weirder is that it detects the phone in Odin mode and even installs the correct drivers. I've tried just about everything I could think of, such as the following:
-Cleaning the microUSB port with alcohol & new tooth brush
-lifting the microUSB connector slightly
-Using a toothpick to try to pick out any residue in mUSB port.
-Connecting while TWLaucher is set as default
-Using Wireless & Network setting > USB utilities.
-Taking out the sim card and external microSD card and booting & rebooting it.
-Restoring the stock Firmware
-Different wires, including an untouched mUSB wire that came with the phone.
-Different computer that doesn't have Kies or the said drivers installed. (Still didn't make a notification sound or bring up the "new device" prompt)
I just want to make sure I tried everything possible before sending it in for repairs.
EDIT: Oh forgot to mention that I had other problems before getting to this one. About a week ago Car mode would always activate by itself constantly. Even during use. Also the phone would refuse to stay turned off. After booting down, the phone would turn off. However, after some random amount of time, the phone would turn on by itself. During that time, connecting the USB wouldn't keep charging the phone. The phone would go between connected and disconnected randomly. Sometime off and on multiple times with in seconds. Other times would charge for hours and randomly stop charging. I've gotten the phone to charge whenever its connected now by cleaning the port, but the computer still can't recognize it as a device. Also the screen will randomly turn on, plugged in or not, and I have to manually turn it off again. However, if I turn it off right away it seems to lock up. So I have to unlock the phone the press the power button again to lock and turn off the screen. Don't know if this information helps.

Try another usb port, sometimes that helps or reinstall the usb drivers in Kies
Ignore, hadn't read all he'd tried.
Bump: Additional information.
Same problem here
I have exactly the same problem!!
My thought is that the USB connector get wet and stopped working properly. As fas as i know, USB connector is composed by 3 cables, one for charging, one for data transfer and another one to detect Car Dock.
It seems that Odin is using Car Dock cable (?¿?¿) instead of Data, so you can use Odin and not Data.
Also that would explain why car mode just kicks in by itself (short circuit between car cable and probably power cable).
I will also sent it to a SAT, since i tried everything via software....
I have the same problem. Try plugging into a mates laptop, see if it works on their one.

In sum, earlier today I was using my phone with no problems-- calls, texts, using apps etc. I went to 'close my screen' when I was done using it and I realized the side power/lock screen button was not working and my screen was not responding when I wanted to lock it. I removed the battery hoping it would reset the phone and fix what was wrong but now my phone will not turn back on. I plugged the phone into the wall for at least 30 minutes as well as plugging it in the computer for quite some time. No response from the phone at all. (no charging icon, computer is not detecting the usb cable when plugged into computer, etc.)I also held the buttons down to try to power on as well.
I was wondering if there was a way to fix this problem, or somehow retrieve files (mainly pictures) from the phone,
Thank you for your help. Any feedback will be greatly appreciated.

I attempted to hold volume down, power and home buttons but the phone did not respond. The computer is also not recognizing it while plugged in via usb. The button does not seem to be 'stuck' as i can still hear a slight clicking sound when I press it.
Try removing the battery and hold power down for 30 seconds and then try installing the battery again.
Try that ^
maybe a jig might help
Hi,
I use Uhappy UP920, chinese phone, 6 months old,
my power button is sometimes hard to press, it is not working so good, so, I used IDE terminal in my android kitkat to shutdown my phone. I used next commands:
su # to become root
shutdown -k
I saw it is switching off, but during shutdown, phone is not totally shutdown than there is still the name of the phone on the screen and it is frozen. I can press power button how much I want, no result, I tried to press it in the same time with volume button, no result. it is not possibly to remove batter and to put it back.
so, this is not about locked pattern, about working phone so I could install app for changing power button to volume button, this is about frozen android software, I can't start it, when I use USB cable, computer doesn't recognize the phone, so, battery is not charging. I don't have ac adapter, I use USB to charge it. but battery is not totally empty, battery was 34% full when I tried to shutdown the phone.
any help?
is there any software I can start from computer and push the phone to start?
in this moment I use windows 7 but I can try Linux too, as I said, when I put USB cable in PC and my phone, nothing happens, PC doesn't recognize the phone, phone is not recognizing USB cable, batter is not charging as it does usually when I plugin the cable.
hi, I don't see option to delete thread/topic, i solved problem with pressing power button very strng on the table, it was finally shutdown and system booted again. problem solved.
My phone's power button is busted and my phone is off. Is there a way to get adb authorization?
Note that my phone's USB debugging is already on. I have also allowed USB debugging once but I didn't check the box to always allow.
I know this post is almost 3 years old lol, but i want to try to help, Hopefully you still have the phone!
To power the phone on, try to take apart the phone and use a wire to connect power from the battery or USB to the power button output terminal (i am not sure if this can cause any damage!)
