USB connection is not stable - Nexus 6 Q&A, Help & Troubleshooting

Soo I am not sure if anyone else noticed but when you plugin your USB, you see your device is charging like me you would see a green led go on (custom kernel) and it's charging
But try now wiggling the cable or whatever and you'll probably notice it will stop charging and will starts charging again
I noticed this especially in my ubuntu vmware machine where VMware was detecting my phone was disconnected/connected and begun opening up like a 10 dialogs showing the internal storage
I am not even sure how to fix such a strange thing, even the nexus 5 had this issue
Anyone else is having loose usb connections or that you have to push down or up to get the connection right ?

I've never seen this either. Not on N6 nor N9.

I've had this issue before, but it was years ago with an Evo 4G. It turned out to be the cable. If the two little "teeth" on the end of the cable get worn, this problem becomes more and more consistent/noticeable.

As he said, its a common problem among all phones that use MicroUSB its due to port fatigue from constantly unplugging and plugging the cable. I have this problem with my Samsung charger when used with my 6 and my friend has the same problem with that cable and her Moto X, I don't use the stock cable that often so it fits well.

ATT Tilt freezes when plugged into USB!!!

Help! My tilt freezes up suddenly and then reacts extremely slow to any inputs. I will push a button on the touch screen and it takes the phone about 3-4 seconds to react to the input. Any ideas on what may be wrong and how to go about fixing them? Also, the phone has problems every month or so about going into the 4 color screen when booting up and not starting properly (not sure if this has anything to do with it...very annoying!!). Usually happens though when the battery is drained. Any help would be excellent!
if by USB you mean the computer's USB port, is ActiveSync syncing when the tilt slows down? because I believe that's normal when ActiveSync is actively working in the background...
USB meaning plugged into my laptop...
...and active sync is not even recognizing my device. Everything i do on my phone is delayed a couple of seconds. When i unplug it from the computer through the USB cable everything runs at normal speed.
Another Problem
I tried a hard reset through clear storage (copied all of my contacts to the sim card since my phone was not syncing) and when the phone booted back up it started in the infamous 4 color screen (anyone know what the actual name for this screen is?) and won't turn back on properly!

I got a similar issue with my Kaiser. Pluged it via sync cable to my laptop/PC, and it would freeze both sides (PC and Kaiser). It is definitely a mini-usb issue, a pin is bend, creating a bad contact. If I slightly move the plug in the mini usb, it will eventually come to life. If the cable moves to the right again, it will freeze again. This isn't happening with a wall/car charger however.
Could be you're facing the same problem. Did you recently damage the mini-usb (by inserting the stylus inside instatd of the soft-reset button, like most of the people lol).
Thanx!
Now that i examine it, the USB is slightly damaged on the inside..will try a different one...
Will try when phone actually boots up properly.....
Still Freezing
Got my phone to finally boot up (after numerous attempts) and I used a brand new USB cable and it still is going reaalllllllyyy sloooooooowwww. It also won't sink with my computer. Anyone, please HELP!

Actually, I didn't mean that the cable was damaged, but the mini-usb plug from the Tilt itself. Have you tried holding the cable while pluged right or left and see if tht Tilt reacts normally ?
That didn't seem to make any difference either. When I plug it into a regular charger it works normally.
New Discovery!
My headphones now do not work either. To recap, connect phone through USB to my computer, the phone moves as fast as my grandmother but though it still charges the battery. My regular phone charger works fine and the phone moves as fast as Micheal Phelps. Though my head phones perform sexually like my grandfather, they don't work at all.
I don't get it!
This may be the most unreliable phone I have ever experienced in my entire life. Now the head phones work after I put them in very slowly but when I take them back out of the mini USB port the regular speakers do not play and sound. When I plug the head phones back in I hear the sound through the ear buds. On a more disturbing note, I guess my grandfather is taking cialis. My mini USB port is just messed up!

New BL + powered off USB charging = windows BSOD?

So two key events happened with my phone - the replacement battery I ordered finally arrived, and I also crawled out from under a rock and flashed the ICS partition and pengus77's CM10.
I was advised to calibrate the replacement battery by charging it from 0 to 100 with the phone powered off. So I streamed a random high res youtube video to drain the battery as fast as possible, then powered off the phone and plugged it into a USB port on my work laptop (a HP Elitebook running Windows 7 Enterprise x64).
The phone started charging (battery animation screen appeared) - and then my laptop started to install drivers. A few minutes later, I got a windows BSOD - yes the blue screen of death, not the black screen on android.
I initially thought something else caused the BSOD, so I left the phone plugged into my laptop and rebooted. As soon as my laptop got past the "starting windows" screen, it BSODed again. Didn't even get to the "Please wait..." screen.
Tried to reboot again - BSOD before getting to the "Please wait..." screen. Finally I suspected my phone was the culprit, so I unplugged it. Another reboot - it successfully got to the "Please wait..." screen, and then I plugged in the phone (still off), triggering a BSOD in under 10 seconds, before I could even get the field to input my password.
Rebooted with the phone plugged in but powered on this time, and my laptop fully booted all the way, no BSODs. But if I powered off the phone and plugged it in, BSOD! Looks like I'll have to wait till I get home to my AC charger before I can calibrate this battery
This is quite strange - I never had any problems like this on the old GB partition, if I were to plug in my phone to the laptop with the phone powered off.
Has anyone else experienced such an issue before? If it helps, my work laptop is a corporate machine so I don't have admin access over many of its functions (though I can still install and uninstall programs like normal), and it's loaded to the brim with corporate bloatware, and it's possible these properties contributed to the BSOD.
Charging(forming) new battery via usb is never recommended to be honest
Most usb device don't provide enough power or stable voltages like charger designed for our phone
I personally never liked charging via usb(most usb hub's dont work properly also if they need to provide current to hungry device(our phone example)..
I have no prob's with that options and also using custom battery 1700mah...
I have no sod's on win but have read that people had problems and sods sometimes with usb charging...
It's hard to pinpoint exactly where problem lies,could be your low power usb on motherboard crashing your win or something else..
Hmm that sounds likely. I'm back home anyways and will use my AC charger to condition the battery.
I remember that on the old CM10 nightlies (before the call bug was fixed), the USB charger always BSODed my phone...
... an easy solution would be to start using a real operating system on your computer instead of windows

Believe me, I do - I use Linux as my main OS on my home computer, and only boot into Windows for games
However this is a corporate laptop that doesn't actually belong to me and I can't meddle with it like that.

[Q] One more charging problem with Nexus 7?

Hello! After some experiments with POGO contacts on my Nexus 7 3G I have the following situation:
1. The normal USB-charging can not properly start. The battery state in the Settings menu eventually changes from Charging to Discharging and back, the battery level goes down as it is indeed discharging. If the tab is off, then the charging animation is not shown completely in an infinite loop.
2. No any connection can be established with a computer using USB cable. Windows 7 machines just ignore this connection without any traces. Windows XP machines repeatedly show warnings about a non-recognized usb device although all drivers were preinstalled.
3. If I put a USB-OTG cable into the tab (even if the cable is empty from other side) android shows that the battery is charging. Neththertheless, the tab in this state correctly recognizes flash drives as it did previously.
4. The POGO charging contacts are alive. The charging is normal. Moreover, this charging alllows to normally connect the tab to computer via USB cable.
I used the last feature to return to the stock ROM and to lock the bootloader, so the device is ready to go to service. But are there some chance to fix the problem by my own?
Thank you!

[Q] Charging problem

Hello everyone.
I have a really big problem with my Xiaomi Mi3w (Cancro) and i haven’t find a solution in months.
I have an issue with the battery(?) or with the micro usb connector, sometimes i can’t charge my battery, no matter what or how, i can’t in any way.
When i connect the phone to the wall charger it doesnt charge or it even drains the battery, even if it’s off, it happened that some times when i connect the phone to the charger at 20+% battery after some hours it’s at 10%.
When the phone behaves like this and i try to connect it to the pc it can’t seem to hold the connection for more than 3-4 seconds, it continuosly connects and disconnects and it’s impossible even to open it in explorer. Obviously it’s impossible to charge even in this way.
At first i thought that it could only be a hardware problem (faulty connector/charger/cable etc)
but the last time i had this issue (today) i discovered that i can keep the connection between pc and the phone using fastboot. When i use fastboot the phone doesn’t disconnects continuosly so i can say that in 99% it’s not a connector/cable problem.
Could it be a kernel bug? I know that the kernel it’s active even when the phone is off but in charge, this could explain the charging problem even if it’s off.
Another thing that i discovered is that when the phone is on the connection to the pc gets more stable if i turn off debug mode ( can keep the usb connection on for more than 30 secs but i can’t seem to charge it anyway).
Things that i tried to solve the problem:
-Change the charger (1st charger is xiaomi’s orignal/ 2nd it’s a sony with output 5V/850 mah/ 3rd is a lg 4.8V/1A/ 4th is a generic tablet charger which came with my acer iconia with 5V/2A) none of these solved the problem.
-Change the cable (used 10 and more different cables, every cable was tested with my other devices and all were working well with my moto G and acer iconia)
-Fastboot install of both stable and developer rom
-Clean fastboot install of both roms (formatting both systems earlier with cwm)
-Install via cwm of ivan 4.4 aosp and cyano 12 (both of these uses the same leaked kernel right?)
-Cleaning connector with a neddle, soft cloth and some alcohol
I’m not sure about this other point but the phone seem to get in this not charging state when the battery gets below 30% and i keep it uncharged overnight.
So i thought that i could also be a problem related to the governor used by the phone when gets to a low battery profile and specifically when this governor tells the phone to get in deep sleep.
(this could perhaps explain the problem of both cyano and ivans roms random reboots and the workaround using partial_wake_lock)
I hope that someone can help me to solve this problem because my device is useless now
Thanks in advance to everyone
i have the same problem with my MI3W. Sometimes i can charge it while smartphone is power off.
I tried with another battery. I am waiting for a new usb connector flex to check too.
Do you find any solution?

I think i might be having the same problem. My phone started acting weird at the exact same condition. The charging connection kept going on and off. Felt like hardware issue at first. Charged my phone somehow to full charge and reset it. Looks good now but still skeptical.
Fingers crossed.

Hi i resolved the problem some time ago, cleaning the connector with a very tiny needle, i didn't go very far the first time that i cleaned it, probably it's only dirt, try cleaning it yourself and see if it resolves the problem
going fine

Never faced the problem again, though i have changed roms.:good::good:
Anyways, hope it never comes back again

Charging delay issue

I'm having a very strange problem. When I plug any USB charger into my devices micro usb, it immediately connect (I use lightflow and get a light indicator as soon as I plug it in). However, it will take about 5 extra seconds for the device to actually begin charging. (indicated by the lightening bolt in the battery icon). Anyone know why this is or how to fix? I'm hoping it's not a hardware issue with my device.
This is also causing any PC to not recognize the device (regardless of ADB, drivers, USB debug, MTP, etc.).
Thanks

I do not think the two behaviors are linked. As I posted on your other thread, mine has the same delay when plugging in the charger. However, I have no problems with PC recognizing device. Explorer can see my device's SDcard. And ADB works flawlessly.
any fix on this? Mine has been doing it for a month or so now. Also my battery has went to **** as well. Also - did you buy yours from qualitycellz?
