A few months ago I plugged my gn into the pc and nothing happened. The pc use to recognize it and i would transfer files ect. now nothing. I have turned off usb fast charge and it still doesnt work. I also just purchased a samsung MHL and it doesnt work either. I had it plugged in and turned on NFL mobile app and it said (error tv out plugged in) so the phone knows it is there but i get nothing out to the tv. yes I have the power plugged into the device. The phone screen does go into side view as soon as I plug it in but nothing shows up on the tv. Im wondering if something is wrong with my phone or if there is a setting im not aware of since both of these are not working.
Im running aokp jb 3 and faux kernel. I would appreciate any help with these issues.

Try flashing a different kernel for ****'s and giggles. I haven't used MHL with faux yet but I know it works on LeanKernel. Just a shot in the dark.
~~~~There is no spoon~~~~
even i am facing the same issue. i have stock jb version on my galaxy nexus (intl version) and when i connect the MHL cable, the screen rotates side ways but nothing gets displayed on TV. let me know if you have tried flashing with a different kernel. Appreciate your help.

I rooted my phone and have it with the latest calkulin rom.. the problem is wen i connected to my computer my phone still thinks its charging. and i have no option to turn on the usb mass storage.?? so i dont know if my phone is defected or is it a rom. issue..yet i already tried 2 roms flashing them fresh.. but nothing seems to fix the problem...does any one have any idea what causes this???
settings>wireless and network>usb utilities
With the phone unplugged from the usb click the connect button then connect the usb. You should recognize the standard usb screen at this point.
Some cables (notably most LG branded... But there are others) just don't work... Damned if I know why.

I would flash it back to stock if you already played with different cables and fixed your settings. Getting it exchanged should be easy if your still having the problem on stock.

i tried..odd..
i think it stated when i activated power saving mode..
im testing now,..
ok so i shut off power saving mode rebooted my device and bingo..odd ah...
I restart my computer when that happens. For me I believe the issue is caused by plugging multiple phones into my pc to load files. This assumption is because I never had this trouble until I started loading apps on my girlfriends bionic as well as my hercules. I am using the cable that came with my g2. My hercules didn't come with cables.
Another fix is WiFi File Explorer. What I like about this fix is that it saves wear and tear on the micro usb jack.
true i will try that.thx

Youve tried two different power sources, what about a different USB cable? Had that issue before where the cable was bad and only noticed when other USB devices werent connecting through it..or intermittently.
yes i tried different usb cables, different power outlets and different computer's.
also i noticed that when its actually charging on the PC, i don't get the small usb icon on the notification to copy files from pc .. i need to power off/on the phone.
ever happened to anyone ?

Ive never read that here, i have a Telus one also and it shows up right away. The odd time ive noticed that ill hear the usb unplug/replug sound from my pc and the phone will show the USB Connected on the status bar as though it somehow reset its connection. But never had an issue where it stays disconnected.
I also only got that issue with certain roms, i dont remember which though. I ran painlessly on Juggernaut for a while and right now im on Touchless and its also perfect.
I am running on Juggernaut, i recently did a clean install (wipe data .. everything) i was having few issues, i though maybe that would fix the issue.
the phone at times thinks that i have plugged the charger in to charge
and u see the battery icon changing. weird...
Have you tried charging with the phone powered down?
Ok so I didn't know how to word the title lol. I woke up this morning my nexus was plugged in through USB to the wall, working just fine. I drove to work and plugged it in like I always do. Left work I do the same thing usually, plug it in on the way home and it was charging. I get home and plug it in to my ps3, nothing. so then I try the wall charger, again nothing. So I restart numerous times, then turn it completely off, still not charging. I then decided I'll make a backup on cwm and restore it. Charging from USB port works again now.
Sorry for the long explanation it's just really weird and I was wondering if anyone else had anything like this happen top them?
I forgot to mention I'm running the latest eclipse ROM with the latest trinity kernel (384 gpu)

Hello all,
I have a nexus 7 2013 and I am looking for a kernel that supports otg plus charge. Now, I know elemental x (by flar2) and a few others have this but the ones I have found do not support hot swap, or unplug and replug without rebooting. I am pretty sure Timurs kernel supports this but he wants $36 to buy it and I would rather not spend the money without trying it out first. Specifically, I have a fixed in-car installation and a febon100 UVC video grabber to display a backup camera. When the car shuts off, the febon will be disconnected from the usb side of the nexus, and the only way to reconnect it is to reboot the tablet with power connected. Anyone have any ideas? Thanks for the help.
Ok so I figured part of it out. After the device looses and regains power, these two commands simulate the usb disconnect and reconnect and seems to work (only tried it a couple times)...
Code:
echo "2-0:1.0" > /sys/bus/usb/drivers/hub/unbind
echo "2-0:1.0" > /sys/bus/usb/drivers/hub/bind
However, I have another issue. I am using the elementalx kernel on android 4.4.4 (currently on Carbon rom but have tried stock and other roms as well with same outcome). When the tablet reboots with the otg cable connected, it does not charge when it first starts up. To charge it, I have to physically unplug and replug the cord in the nexus. Any ideas?

Just use tasker to run the commands at startup...
Does this set of command still work with lollipop? I just tried a few times and it seems to have made no difference.
Thanks in advance!
Yeah im in the same boat. Soooooo many problems with this ****ty tablet. Knew i should have installed an iPad. They said this is the 'best' of android. It's ****ing terrible. People who are thinking of installing an android into your car? A word of advise. Dont do it.

It's been almost a year any way to accomplish charging without having to physically unplug the OTG and plug it back in. Im have timurs kernel but I want to use elemental so I can use marshmallow. Timur accomplished it somehow. Someone has to know how.

It is actually trivially easy to accomplish - on any kernel - it is called Qi Wireless Charging.

Test results for Android 6.0.1 Stock + Kernel 'Quanta-V7-Flo' with active 'USB Host Mode Charging' and inactive 'fast charging' (N7 is only is use when its connected to the USB Power):
Ampere values checked with one of the cheap 'USB Charger Doctor Voltage Current Meter Mobile Battery Tester':
0.45 A for N7 only
0.61 A for N7 + USB Ethernet adapter
I don't use the N7 in a car setup but this should be important for such setups:
-If the USB Y cable is connected before powering on the N7, the USB device was usable in Android after startup without need for reconnecting the USB cable
-If the USB was unplugged and reconnected the device, it was usable in Android
-Important: If the N7 goes to sleep, it can't recover the USB charging and USB devices after waking. You should set the display timeout to always on, which is right for a car setup or am I'm wrong?
I'm happy! :good:
I tried quanta. It does work except for on initial boot. Have to unplug and plug it back in to charge. Then it works fine turning the key on and off for power. However it doesn't mount the OTG devices again without unplugging it and plugging it back in.
Edit: I also have another problem was at work and didn't have time to add it. But my Nexus thinks it's still charging after disconnecting it from power supply through the OTG cable. When I turn the key off it quits charging for about 1 second then switch's back to saying it's charging again and continues to say it's charging even after cycling the key on and off. Only way to fix it is to disconnect the OTG straight from the tablet and plug it back in or boot it into recovery then back to system. Has done this thru multiple roms and kernels. Only kernel it doesn't do it on is Quanta. The thing is it didn't use to do it at all no matter what rom or kernel I was using. I even went as far as to change the charging port board cause I had another one in a old junk Nexus I have and still didn't fix it.

I've used it before but not on my current setup.
Assuming one of these kernels provides OTG + Fast Charging, what are the options for the Power-Down + Deep Sleep, then Power-Up + Wake?
