Develop Bugs

Something weird I noticed.

So I got my phone on craigslist from a guy. Just the phone, no cables or anything. I tried using my HTC usb cable, but it wouldn't work. I had to buy a legit Samsung cable for it to work. Now that I got rid of the stock ICS and installed a jellybean ROM, the HTC usb cable works now! Which is good, cuz I lost my samsung one.
Any idea why this would happen?

I don't think it matters or will help anyone. Just use OEM cables and one less thing to worry about.

Standard USB cables is universal, they should be all the same, with 4 pins:
Vcc, Data-, Data+, Ground (of course 3.0 have new stuff)
Maybe the HTC cables have built issues or you were using a USB port that wasn't delivering full 5volts. Sometimes I tried flashing Odin and it failed on cheaper USB cables. And since my desktop have weak USB power output, the file transfer to the Nexus fail sometimes unless I use a USB cable with dual connectors connecting to two full USB ports. But I don't think there is any prevention method to make one brand of cable not work with a certain phone brand, this is a universal standard, not Apple. Which is why I refuse to buy Android tablets that use proprietary ports.

Maybe he had something borked in his rom and didn't know and that was why he was unloading it.
butter and jelly please...

Hey its from Craig's list. Anything is possible...

yeah any micro usb cable should pretty much work. everything ive tried works fine (blackberry, samsung, htc, generic ones)

I had the same issue with me g2x charger. Only reason why I wanna use my g2x charger over the Samsung OEM one is because the Samsung one does not fit with my case so I'm forced to take off my case every night so I can charge

He probably had fast charge enabled, which was wiped when you flashed stock JB

Battery not charging even swapped the hardware,

It been a while sense I've messed with this. I have two galaxy nexus one is pretty tore up so I've been using it to charge my batteries. My good one will not charge even after micro usb port swapping.
The one that won't charge my batteries: I don't know why it won't charge. I swapped the hardware. It all started when I flashed slim over I think it was Kang. While I was on Kang(I think it was that one at least) I messed with some advanced battery settings and forgot or didn't think it metered switching them back. I can only assume this is the culprit.
It will recognize the AC charging but it will not charge or it will only De charge my batteries. If anyone can suggest anything please let me know.
Thank you.

What do you mean "swapped the hardware"?

I swapped the micro usb port

Flash a stock build to isolate it as hardware.

I've got one that is doing the exact same thing. It connects to the PC ok, and shows the charging symbol but when you check under status it shows as not charging.
I took it completely apart, cleaned the logic board with a soft bristle toothbrush in case it had any thing that might be causing it to short, and even replaced the usb charging port flex cable.
I have noticed that when I plug it into the usb ports on my HDD docking station that it makes a low barely audible static like sound. my other working Galaxy Nexus doesn't do this.

OK an update to this, if I run the factory Jellybean 4.1.2 image or CM10 it still shows the charging symbol and shows as not charging in the status info, but if the phone is left alone the battery does charge. If I run the 4.2.1 or 4.2.2 factory image or CM10.1 it doesn't charge unless the phone is turned off.
very bizarre.

That is somewhat odd that it will trickle charge yet. That usually is indicative of the usb flex being bad ... that or a bad charging cable but i assume that you have tried that already. Do you have data connectivity yet on this device? Usually you lose that when something like this happens, at least when it has for me. Do you flash the factory image via fastboot or odin ... You could try to odin it to ensure that everything is stock. But since your bootloader is charging that kinda rules out hardware especially since you said that you have changed it already. Only other thing i can think of is a kernel issue but that would be taken care of when flashing stock if you flashed via bootloader.

[Q] Unknown device found when connecting gnex..

When i connect my gnex to the computer, a msg pops up saying "device connected has malfunctioned........". But when i connect my Xperia X8,it works normal and fine with all adb and fastboot functions working normal.
I tried uninstalling drivers but it failed too Moreover,whenever i connect my device with android debugging enabled,nothing happens..It only charges my phone via usb but adb doesn't works.I see no response whenever i connect my phone..pls help me..
one more thing, i tried flashing 4.2.2 factory image..but for flashing image also my computer needs to recognise my phone..pls help me

Strange I would clean the USB port re seat the battery and maybe try on a different pc.

Ya its strange..I tried each n everything including cleaning ports and changing too!! The most weird part is except my GNEX, all my other devices works fine

I have been dealing with this very same issue for about a month.
So far, without any success, I've tried:
- connecting my gnex to computers running windows 8, windows 7 and Ubuntu. (Removed and reinstalled all drivers using multiple routes.. Gnex toolkit, Samsung drivers, pdanet etc.)
- I've cleaned the USB port multiple times (gentle toothpick, canned air, rubbing alcohol)
- I've disassembled the phone and very carefully removed the USB flex cable to check for damaged ribbon cables.
- reverted to stock ROM
- tried both CWM and TWRP recoveries
I'm now out of ideas. However, there is a replacement USB flex cable on amazon for roughly $7. This is my next and probably final option as I'm no longer on contract with any service provider and use my gnex as a WiFi/sip device.

Is your problem fixed now?

One more weird situation has begun..my gnex charges itself(even though i haven't connected any charger)..it actually doesn't charges but it seems as if i am really charging it! This happens after every few minutes..

No. Still without success. Have not yet ordered the replacement part.
If your biggest issue is transferring files though, there are several apps like Google drive and dropbox that can come in handy as well as file explorers that allow network access over WiFi (I'm about to us ES file explorer to transfer a 2gb file... Hopefully)
From what I've read here on xda and elsewhere, this issue will likely lead to a complete failure of the USB port, meaning no charge either. Best of luck to you that this doesn't happen.
**edit - if you are already rooted, be careful not to undo it, because I've not found a way to root without USB. Also, there is ADB over WiFi, I just haven't messed with it.

Exactly ! i am facing the same situation i.e. sometimes my phone charges and sometimes doesn't..even when connecting to computer ,adb doesn't work and it may charge the phone sometimes..
Is my gnex's USB port damaged or is it software related issue?

The phantom charge is another symptom of the faulty USB port. I've yet to experience it myself.

What does "phantom charge" means?

By phantom charge, I mean that symptom you described of your phone saying it is charging even when it is not plugged in.
I have ruled out software issue for my phone, and likely your phone as well but that is your decision. To me, this is definitely a hardware issue.
The part I linked to is twice as expensive as I remember. Perhaps do some more searching for a better price.

Pc not detecting android but charging

Hi this recently started happening again. Basically plugged my s3 in via usb. Nothing shows in my computer, but phone remains charging. I have tried uninstalling and reinstalling all samsung usb drivers but it does nothing. Tried installing kies/older usb drivers, still no luck. Regardless of if there are drivers or not on my pc, there is no detection what so ever. My pc was detecting my phone perfectly before. Anyone know the solution to this?

try roboot ur phone?

Tryall usb ports on the computer. Is it seen in device manager?
If so try uninstalling from thrre. Then reinstall drivrrs. Uninstall kies and don't reinstall it.

Already tried restarting phone. The samsung drivers are not listed in device manager. I have already uninstalled kies.

Try a different USB cord. I had the same issue with an old USB cord I got off eBay, I would have to adjust the cord a certain way and keep it there for the computer to recognize my phone. I got a new cord and don't have the issue any more.

If you are using a desktop you can try to power it down, unplug the power source, reboot it then try again. If on a laptop, you can try to unplug the power source as well. As strange as it sounds, I was having a similar problem (on windows 7) and this strange fix works every time it happens to me

+1 I have bought a bunch of USB cords online, half of them will only charge but not recognize the device. I would try a different cord first.

I'd say at least try two cables, unless you can confirm one to be good by testing on another device.
Also, try on a different computer. This will at least tell you if the problem is your computer or your phone.

I know, I've lost count of how many cables I've gone threw since my first android device. I found one that was 3 ft. Long and charged my phone quickly, 3 months later it stopped working. I would get one from Samsung but they're too short. Its hard to find the perfect micro USB cord lol.

Yes but as I mentioned before, these cables go bad all the time. Usually wires come loose in the tiny connectors they use. Unless you somehow manage to keep it straight and flat all the time, and never pick k up your phone while it's plugged in, the cable will eventually go bad.
Sent from my SGH-T999V using xda premium

I had the same problem and it turned out to be the cable. It was the one that came with the phone. My phone was bricked because I hadn't checked the md5 of the rom I was flashing so I thought that I had really screwed something up when I couldn't even get the phone to connect to Odin. I was about to file an insurance claim until I finally tried another cable and it worked instantly.

we have the same problem
I tried another USB cord I tried another PC my phone can't detect at any PC but I have all the drivers for my device even the other android phone still can't detect

Where did you get the Samsung drivers? Did you try other USB ports?

This happened to mine as well. I have taken it apart and tightened the micro usb socket twice now. Works for a while but the overall design is the problem. This has always been a problem with micro usb and is why proprietary sockets are far superior to micro usb despite all the blather I hear about how convenient micro usb is. You can convert proprietary ports when needed and they dont fail like this.

My other two Android devices are like two years and both use micro USB, and they still work fine. It might be the design of the Nexus 7 itself.

I had this problem with my old Samsung Captivate. It would get so bad the cable would actually fall out. Have you tried a new cable? I thought my phone was damaged but I ordered a new OEM cable because I damaged the original and it also happened to fix the charging and loose connection issues. After a while, it happened again so I just ordered a few more cables on eBay. The reason I chose OEM cables was because the Captivate had a sliding door for the USB cable that often wouldn't accommodate a standard connector. After that experience, I try to stick with OEM cables when possible, just to be safe.

Mine is different. The micro USB would perfectly fit into the port. I would feel and hear a confident strong click and the movement is minimal. However, it would not sometimes charge and have to play with the cable while at the port.

Funny... I though I was alone 'cause no one would write about it..
I got 3 cables, all with slight different behaviors but generally loose, one of them actually falls off.
Patience is highly and thoroughly tested when I want to transfer data to my nexus.

Mine is loose. I have to slip a piece of paper in with the cable to pack it. Otherwise it won't charge.

Mine is loose but that's my own doing lol but using a different usb mini seems to work

If it's covered under store warranty then sure, you can take it back. Otherwise I'd contact Asus about it.
