Hey guys,
My keyboard is quite laggy and missing keypresses when plugged into USB. This does not happen when plugged into AC! So strange. I tried turning ADB Debugging on/off, and it didn't make a difference.
Has anyone else noticed this?
Any suggestions?
So I have a new lead on this. I think I know why it is happening. My touchscreen receives ghost touches when USB is plugged in. If someone could please check this on their phones as well:
1) Install "Multitouch Test" from the Play Store
2) Open the app, touch and hold two points (there should be 2 colors under your fingers and that's it)
3) Plug into USB (in a computer, not outlet)
4) Open the app and touch and hold two points
For step 4) I see additional "ghost" touches quickly appearing and disappearing. Funny enough, the ghost touches stop happening if I touch and hold my laptop's metal case! So it seems to be some sort of grounding issue?

Thanks!
I re-tested this at work and it isn't happening here. Could be something to do with the cable at home or the laptop.

Should be the charger, I have one where it is happening too. The phone freezes every once in a while while charging with it...

It seems to be my laptop. I brought the same cable to work and it doesn't do it here. Also, the phone will freeze/crash when plugged into my laptop and stress tested. Strange.

The faulty charger in your case is represented by the laptop.

HELP!!!
I don't know what goes wrong...in recent days, the screen auto turn itself back on even I press the right side button to close it... I don't know what to do now.. is there some app run itself to turn the screen on??? it's very annoying.. how can I found out the root cause for it and fix it???
Thanks a lot!!!
Your USB port is probably messed up and your screen is turning on because the phone thinks its charging.
Clean out your port and make sure the connector is straight.

You mean physically clean the USB port on the bottom of the phone? But the screen auto on issue happens even when my phone is not plugged in USB.... Thanks

El Daddy suspects the USB port is somehow dirty enough to make the phone *think* it's being charged, wich causes it to turn on the screen. You could test this by using the Tasker app: make it write to a logfile or give a toast/notification on the state power (any). If it logs a power source while there is no cable connected: tada.
I'm not sure if there is a permission in Android that allows an app to turn on the screen. I doubt it however.
Human interesting insight... is the application called "tanker"? Is there any free application can do this log?
I once thought there are some app that used my GPS or running in background to periodically turn my screen on....
It's called Tasker. You can download a trial version (7 days) here: http://tasker.dinglisch.net/download.html
it's hard to say how many applications can do this. you'd better list all you applications here.
The touchscreen on my 2013N7 fizzled out earlier. Responsiveness has been on and off for the day - for a few hours it would improve after I press on a certain spot on the back of the device, but after that it has gone entirely. I've rebooted several times and there is no response.
I'm trying to use android control (http://forum.xda-developers.com/showthread.php?t=2786395) to just access it and get my data off of it, but when I plug it into a PC, the PC doesn't recognize that there is a device plugged in at all, even though it'll still charge the N7. It's completely missing from the device management list; adb shell can't find devices plugged in. I've looked around for possible fixes, but all of the ones mentioned require being able to access the tablet.
I'm at a bit of a loss here - is there a way to get the N7 to show up on the device list, or an alternate way to pull data off of it?

The spot corresponds to the plug (att) and now it is time to unlock, reseat the cable and relock it as all of the problems relate to poor contact of the cable.
Same issue here,I am inserting a usb otg and connecting mouse there and then rebooting. This is really a bad issue

I`ve got a problem with my HTC that I can`t solve. First it wouldn`t charge, then the speaker suddenly turns on/off while speaking with someone. While texting, the messages suddenly disappear, so I have to type it again. Then my car navigation app turns on and off for no reason. I installed the antivirus protection and it`s still the same. Then I reinstalled the software , but still no changes. Has anyone ever had a similar experience, and what did you do to fix the problem? Thanks in advance.

R u tried charge your phone with another charging cable ??
Not charging, and randomly going to car mode; both indicate an issue with the MicroUSB port.

That would be my thought, yes.
Although I don't think it explains the other problems. Running the proper RUU (if OP's version has one) may be a good idea, and see if it helps with any of the problems.
So today I tried to use the 3.5mm to USB-C adapter to use wired headphones on my phone. It's been over a month since I've used the adapter and it was working fine. Today it's not working.
The strangest part is if I plug it in one way nothing happens at all. However, if I unplug it and flip it around the phone does detect it but instead of playing music it behaves as if I plugged it into my computer and I get the "Android System - USB supplying power to attached device" where I can tap and select between "Charge this device", "Supply power", "Transfer files", "Transfer photos (PTP)" and "Use device as MIDI".
Has anyone ever had this issue? Phone hardware issue? Adapter issue? Software issue?
I started having this issues while a go and it escalated fast, now everytime I plug my phone to any source of power it turns off
It could be the adapter as well but there is a small group of people having the same issue as me
Same issue here, I have to unplug and plug again my adapter for it to work. It has been several times that I accidently started playing music loudly on the bus.

Well, I haven't had that issue......yet. I contacted Google support. They are sending out a new adapter. Not sure if that's the issue but it's the easiest place to start. Otherwise it's a phone hardware issue or a software bug.

Do you just have to unplug and plug in one to get it to work? Do you ever see the power/file transfer menu? That's all I get and only if I plug it in one way. When the connector flipped over I don't even get that menu.

I am on my third device because of this issue.
https://productforums.google.com/fo...!msg/phone-by-google/-p-F-7Rgtak/zUay6YIZBgAJ
Massive thread about it, Google doesn't have a fix for it yet.
Restarting the phone/unplugging & replugging the adapter usually sorts it out for a little bit, Sometimes it won't stop doing it, Completely random!

It's so strange. It worked for me every time with no issue at all for like 6 months. Only recently did it start having a problem.
Since you are on your 3rd device with the same issue that makes me think it is a software bug not a hardware issue. Otherwise replacing it should fix the problem.
I think the last time I remember it working was late April or early May (hadn't even tried the adapter since then until about a week ago). So maybe a bug in either the May or June update?
I'm having the same issue here. It worked up to within the last month; I didn't notice exactly when it stopped as I'd been using bluetooth headphones more often. Left them at home one day and pulled out the backup USB-C cable for my QC-25 headphones and the phone indicated it was charging the headphones.
Some folks at the other thread said the Android 9 beta resolved the issue, but I updated to the 9 release a couple days ago and I still get the issue. FWIW

Seems to be resolved for me on Android 9...so far.
My aux dongle isn't the problem for me, I've gotten a replacement and it's still didn't work.
I've started facing the same issue from yesterday, is there any solution to this?
I have the Nexus 7 2013 WiFi flo tablet with LineageOS installed.
I’ve not used it in over 12 months but today I was using it.... it turned off, loaded up the Google screen with a locked padlock and won’t go further.
In recovery mode it has TWRP, but the screen and volume buttons are unresponsive, the power button works but I can’t swipe to unlock or click anything.
I’ve plugged it into my MacBook and it’s not detected, I plugged it into a windows laptop and it says the device is unrecognised or malfunctioned.
I installed the android SDK on both and the USB driver on the windows machine.
Also changed between 5 different cables and different ports.
I can’t reflash and I can’t touch the recovery.
What can I do?
Thanks

All these problems, including no USB, are caused by poor connection between the PCBs.
Try this simple trick https://forum.xda-developers.com/showpost.php?p=66952073&postcount=3
If it does not help, you'll have to re-seat the wide, silver cable on both ends. Disconnect the battery first of course and watch https://www.youtube.com/watch?v=C9PwK9eGrCY

I got frustrated earlier with the google screen and I squeezed, the Lineage loading bar came on!
I came here to report this finding and saw your reply... I've tried reseating that cable so I'll wait and see hownwe get on. Thank you very much for the help
