This is a 3 month old rooted 2013 nexus 7 which suddenly has started giving me problems recharging. Here is what happens :
When I connect the usb charger, the charging doesn't start (lightening on icon). To make it charge, I need to shake the tablet, or turn it to landscape, or sometimes holding it vertical will do so.
What is strange is the usb port has no trouble connecting and reading usb storage devices using stickmount which always connects with no problem. So it may not be the usb port that is the problem but the connection between the usb port and the battery.?
Is this something I can fix or do I need to explore Asus warranty services?
Thanks

Hi guys,
My GNex has a problem. Many users seem to have a similar problem but theirs seem to be hardware related and I'm pretty confident mine is software related.
It started a few months ago when my GNex wouldn't charge through the wall charger. I was on a trip with my friends so I didn't have access to a pc and wasn't able to troubleshoot further. The charging icon would appear when the phone was off but when I turned it on it didn't charge. I played around with the phone for about two hours, rebooting, Googling for solutions, changing the USB connection modes in the Storage settings. When I changed from Next Launcher to Stock launcher and rebooted everything was working fine again. However I think it was only a coincidence. Then the problem didn't occur again until now and this is why I think it's software related. If hardware would have been broken the problem wouldn't just have fixed itself like that.
It happened 3 days ago but somehow fixed itself again. I was troubleshooting the issue with my GNex connected to PC and installed Nexus Root Toolkit by Wugfresh. During install my phone rebooted on it's own and suddenly USB worked perfectly again!
However yesterday I forgot to charge and my GNex died. On reboot the issue was back.
"Symptoms":
Phone won't charge with any wall charger (and any cable) unless off
Phone will charge through USB in any mode but PC will not recognize it and install it as unknown device.
USB Debug Icon and Connection Mode notification do not appear in status bar upon PC connection
OTG doesn't work and apps like "Stickmount" do not detect external drives
Attempts:
Gently bending the "tongue" inside the micro usb on the phone in case there is a bad connection
Reinstalling drivers on PC
Rebooting device in different modes including fastboot
Using different batteries
NOTES
This problem started after latest 4.3 update. It has only occured after battery completely runs dry. I have 3 batteries (a bit excessive I know) and an external battery charger so charge is not the issue, I just really want to understand what's going on with my phone.
I'm not ready to Factory Reset or replace the USB port yet, those are last resort options to me. Any other options, especially software related, are very welcome. I am on stock 4.3 only rooted and with CWM recovery.
In Testing menu (type *#*#4636#*#* in Dialer) under Battery Settings my phone also says Charging (AC) when connected through USB. Hope this helps.
Been Googling around for two days now so I decided to make my own thread. Any help is appreciated. Sorry for this very long post.
Fixed it! Tried bending the tongue inside the micro usb again, forced much more this time, everything is working again, for the moment
I've had my Nexus 7 2013 for about half a year and it's had micro-usb issues for a month or so before this, but now it is completely impossible to transfer files or connect to my PC as a storage device. The charging icon will remain active, and it will charge, but it simply either doesn't register, or if I repeatedly insert the micro-USB, the "Connected as MTP" will pop up but quickly go away. My PC tries to install the driver but shortly closes after it registers that the tablet has disconnected.
It isn't the cord as I've tried it with multiple, so I'm moderately sure it's the tablet USB port. Is there any way I could fix this without having to get a replacement and if not, how do I go about replacing it?
Thanks in advance for any help. Anything is appreciated.

A couple of my friends Nexus 7's also got its charging port damaged. I wouldnt advise you to fix it by yourself as it's risky. Carry it by a repair shop. I know that the Usb port is located on a separate board and not with the cpu etc so its not hard/expensive to fix.
Hello to all!!
Let me describe the problem...
The tablet needs to be repeatedly plugged and unplugged for about 10min to start charging...the charger is detected as a USB device.
When I connect the tablet to the PC nothing happens, sometimes, just sometimes the tablet displays "High-power usb device connected", but if I put the tablet in download mode the connection always works, also if I connect the USB-flash device to the tablet the tablet recognise it.
The problem is the charger an the PC...the tablet just don't recognise them...!
I also tried *#0808# ... now I have the USB setting on MTP+ADB .... and I also tried different roms and the problem is always the same.
If anyone know what is going on, please let me know!
Thanks!
Hello dear.
I have a problem with my p601,
I cant connected my tablet to PC.
When i connected, just charging and no any connection.. In odin or storage not show a device, adb not connected...
And when i used a charger show an red stroke on battery icon. And charging is very slowly, during night only 50%.
I'm root my device, install twrp, and install cyanogenmod, but nothing change.
Now whats your idea? How i can fix this issue?
This may be an obvious question but have you tried a different cable or charger? I always found running on stock ROM that charging was an issue unless I powered it down. I have used a 12W Crapple charger and that seems to work ok but charging has never been an endearing part of the this tab.
So in Odin you it doesn't work? Could you have some dirt or contaminants in the USB port, start with the obvious, change the cable, use a different usb on the pc or try another pc altogether.
I had same problem, i noticed that the usb port was loosen little bit, i had to open the tablet apply small pressure with plier to afjust the usb port,,,, and now it's perfect.
Hey everyone,
The type C port of my phone stopped working sometime ago. It only charges. However no dash charge is available. Also when I connect my phone to my computer there is absolutely 0 data exchange happening it only charges. Also OTG is not working aswell. When I connect a OTG device and turn on OTG, it only gives power to the OTG device however, no data connection is happening.
Before you may ask,
- I tried multiple cables and different different usb ports and devices.
- I bought a brand new official dash charge cable.
- Turned ON/OFF Usb debugging
- Put "Default Usb Configuration" to "File Transfer" (as well as trying other options such as USB tethering etc)
- Booted into recovery and wiped my cache.
- Cleared the cache of MTP, Media library services. (as well as disabling and re-enabling them)
- Went into factory menu and ran factory tests.
- Went into fast boot menu and recovery and tried plugging the cable for some data exchange.
- Then I determined that the port is damaged from endless usage for years, bought a brand new type c port (with flex cable etc) replacement and installed it.
and still... There is absolutely no data connection happening from the type c port. Just slow charging and nothing else.
More info:
The usb started working out of nowhere for a brief time on it's on and then shut off again. Which led me to believe this is rather a software issue than a hardware one.
The Microphone Jack is also not working (as they are on the same board with the usb port).
I am assuming the service or software responsible of activating the data connection when something plugged is just nothing working.
Has anybody experienced something like that? Is there anything that I can try to fix this issue?
The only thing I have not tried is factory reseting the phone and I am not sure if that would fix this issue and I want to do it as a last resort.
I just don't want to give up on my 5T as it's still rock solid except for this issue.
Damn bro. I am facing the exact same issue. Looks like this is end of life for OP5T phones? I had bought mine in 2017/18 can't remember now! Let me know if you are able to fix it anyway
I had the same symptoms and it was caused by a poorly designed ribbon cable inside the phone. The cable always has a little stress on it and over time it will break the connector on the motherboard.
