USB HOST and wakelocks [BUG!] - Galaxy S III Accessories

As you can see in the screenshot attached, after using the original Samsung OTG usb cable to mount and unmount several usb storage units, the phone is no longer able to properly go into deep sleep mode with a considerable battery drain.
I have rebooted the phone and looks like it is able to go to deep sleep again.
Good thing the phone boots very fast...

Yep I found this myself and it's mentioned in a few other threads. Only a reboot solves this issue

Also struck this, usually reboot the phone after using USB OTG.

I review daily the i9300 forums and I haven't come across this info yet, sorry if it was already discussed.
It's an important bug to be aware of when using OTG.

I'm not no. Or i haven't enabled it. Where would i find it?
Thanks for the quick reply btw.
No it's not
What kind of computer? Windows,its a driver thing, if its Mac u need android file transfer which is a nifty application u can find for free.

I have the same issue. MTP is selected, but I don't get any signal from windows that a USB device is connected. It's like plugging it in the usb wall charger, all it does is charge it. If it is the fast charge usb, how do you disable it?

Ok, the Galaxy S II looks to have the same issue.

I noticed this problem when I had fast charge enabled on this rom.. I rectified the issue by disabling the fast charge present in AOKP B30..
Navigate to Rom control and click performance tweaks. You should see a checkbox to disable fast charge there.
Restart your phone after disabling it for the changes to take effect..
After disabling and rebooting your phone, the usb should mount to your computer properly..

Well the mtp fixed it. Guess I should have looked into that first. My bad, thanks for the help guys! Now if only I did not keep getting "System UI has stopped" at random times on aokp...
I've tried changing it from MTP to PTP and turning after switching between the two. I've tried two different roms, one based on 4.0.4 and 4.0.3. I've Tried several different USB cables, including the ones that came with my G2x and Nexus One. I've tried it in a USB 3.0 Port. I've tried using different kernals. Even when I get into recovery, windows still doesn't read somthing is attached. I've been transfering ROMS to it via dropbox. I don't think it's a rom issue as it should still show up in windows when in recovery. Also on those roms I made sure that they didn't have "USB Fast Charge" enabled, as I heard that can cause the issue I'm experience. Thinking it was an issue with CWM, I downgraded it, but still no USB. I'm stuck here. Any help is greatly appreciated.
Their IS a fix for this, but we need the code to get into the PhoneUtil menu and turn USB back on.
It's an issue with Samsung phones apparently, and here's a fix someone found a while ago.
http://blog.vacs.fr/index.php?post/...ot-detected-problem-on-Android-Samsung-phones
We just need the PhoneUtil code for the Galaxy Nexus and we should be all set.
It's a HARDWARE ISSUE with the latest batch of GNexs.
My issue is definitely hardware. I sent my GNex back and they sent me back a new one which I received yesterday. I checked and this one wasn't previously rooted or Unlocked. It worked for a day (worked as in windows saw it and I could xfer music/books/comics to it) after I get home from work Windows stopped recognizing it. I did NOTHING to the phone, it just stopped being seen by windows. I only used the cable that came with it and charged it the night before using the supplied adapter, but the USB still stopped working. Last resort I did a system restore to the phone and the USB still doesn't show up in anything ,Tried 5 of my Windows PC's A bunch of PC's at work, my friends Mac, my Ubuntu powered Netbook, my Xbox360 and PS3, even the Transformer Prime using the keyboard dock. This is telling me it's a hardware issue with the Device. Might be somthing wrong with the latest batch of GNex's but the USB seems to give out. Even if I put the phone in ODIN mode NOTHING recognizes it. So, before you all waste your time finding a fix, this is 100% absolutly a hardware issue with these phones, I don't know why, but I had Two bad ones in a row, and am Hoping my 3rd isn't borked too.
I have a bad history with Android phones....My first Nexus One wouldn't stay on, so I got a replacement from HTC. My first two G2x's would constantly reboot, It wasn't until the 3rd one that I got a working one. Now I'm hoping I don't have to go through 4 bad Galaxy Nexus' before getting one that actually works!
I have the opposite luck with tablets....the Novo7, Iconia A100 and Transformer Prime have been perfect outa box. This ordeal with android phones makes me seriously consider exchanging the GNex for an iPhone4s....but the iPhone4s screen is SOOOOO tiny!!!

[Q] Franco kernel and forcing fast charging...

Running Winnner00 CM9 + Franco kernel (tried nightly 160 and stable M3)
Using Franco's app I am unable to enable force fast charging. The checkbox in Settings seems to be ignored. Tried both nightly and stable kernels, reboots, etc. It does work from command line, so I think the issue is in the app itself. Am I missing something here?
Any suggestions?
Does CM9 have the option built in? I know AOKP does. I leave them both fc options enabled (rom & kernel) because I charge my phone in the car waaay more often then I plug it up to the comp. If CM9 has an option for it enable it there.

did you unplug before turning it on? you cant be plugged in while enabling fast charge.
Also, try updating your superuser (even if it says it is up to date). Just a thought as I've read this can cause issues.
Afaik, CM doesnt support fastcharge.

Yeah, basically it is a combination of a few things - one is that even though it says it is enabled at boot time, it is not. You have to turn it off and back on. The second is what you mentioned, you have to unplug it and plug it back in if you turned it on while plugged in.
I ended up using a plug-in for Tasker to manage it, though it is wierdly hard to GET the current state (how hard is it to read a file, apparently hard) from Tasker, though setting state works.

You can check out Secure Settings plugin (sorry, can't post links yet, but search it) - it is great for a LOT of things including this (its under Custom ROM options)

"THANK YOU" (For ur thanks meter)
But, on a serious note, i got the solution for the problem already..
For others out there seeking the solution to the problem, the trick is to unplug and then again plugin the USB cable after you enable the fast charge..
And then in battery stats it should show charging(AC) instead of charging(USB)

Sorry, I missed that this was the issue you were trying to solve. Yeah, when you switch the charging mode, it only takes effect after you next plug in. It will not change your current connection - which can be especially tricky if you reboot while plugged in.
I wanted it to be on by default since I hardly ever use USB for data. I would love to have the ability to have it come up enabled and to disable it, but that does not seem to be how it works - which, I guess, makes sense as you would loose any ability to debug in case of emergency, as in fast charge mode all data communication over USB is off.

If you keep the fast charge option enabled, it would always be on by default, (the way YOU need it), and when ever u want to use the USB, turn it off..
There are plenty of apps on google play which support simple toggle between fast charge on/off.. many of them have widgets too.. which makes it more than easy, just a tap away..

Not entirely true - first of all for this to stay on you have to have Franco's app (or another app that turns it on at boot time) to auto-turn it on on boot - it does NOT keep state across reboots. At the time of the original posting in this thread, the Franco's app did NOT work for this, so you had to manually go into it and turn it off and back on again before it worked - so I automated this via Tasker. Just tested, seems like it is working now (although it takes a while after boot before the setting is applied, Tasker/Secure Settings route is MUCH faster). Secondly, if you boot up with the USB cable in, it will ALWAYS boot into USB mode because of what I said before. (Unplugging it and plugging back in once it is fully booted and fast charge is on, will turn then register it as AC).
But yes, there are a number of other routes and apps to do this.

I said that because mine stays on across reboots..
If your option turns off, Tasker is no doubt the next option..
And regarding booting with USB cable plugged in, i already mentioned in a previous post that you will have to unplug and plug in the USB cable again to enter into fast charge mode with stats as Charging(AC)

USB Issue?

Hopefully you guys can help me out. I'm suddenly having issues with my phone not being detected by my PCs when it is connected via USB.
When i plug my phone into my PC, i receive the error message: "UBS Device not Recognized One of the USB devices attached to this computer has malfunctioned, and windowes does not recognize it." from my Windows XP PC. My Windows 7 PC is unable to recognize the device plugged in.
The strange thing is that even though my phone is not being recognized by the PCs, the phone will still charge.
The phone is not in USB Debugging Mode, and I've gone ahead and flashed 2 separate Kernals on my phone, but i still am having this issue. I have tested this out with 3 USB cables, on 3 separate computers (Work (win xp), Home (win7), and friends(win7)).
2 Days ago the USB worked fine for me as i was able to flash Franco Kernal and JB onto my Gnex, but suddenly it's not being recognized by my computer anymore.
Stumped.....Hoping that this isn't a hardware issue and something that i can fix without having any downtime away from my phone.
Any thoughts?
Try other USB port and other USB cable.
Sounds like you're missing some drivers... Remove the device completely in Device Manager & plug it again. For MTP, Windows 7 should find the drivers online by itself. If you need fastboot access, you'll have to download the seperate drivers for that. I'd recommend the GNex Toolkit in that case since it comes with the drivers included (you'll still need to install them of course )

Thx for the reply,
Yes, I have been using the GNEX tool kit, though not the 7.3 version that was released today. The 7.2 version was being used at home and on my work PC. I usually install the drivers from the toolkit then plug my phone in when done. The drivers have been recognizing my phone but not since 2 days go.
I'm currently trying to find the MTP checkbox in the phone Settings to double check if it's checked, but im having problems locating it.

Ah yes, that is where it was hiding....But unfortunately the checkbox is checked.
This seems like a hardware issue, but I'm not certain since the phone still recharges when plugged in

Could be... Charging doesn't necessary have anything to do with data transfer AFAIK... Do you see something in the Device Manager when you plug it? You might have to right click & do a re-scan to force detection.

Device Managers shows "Samsung Galaxy Nexus ADB Interface". The drivers look to be installed.
Also another odd thing, is that after i charge my phone and unplug it from my PC, it will continue to show that it is charging on the lock screen and in the top right corner of my phone. However if i go into Settings ---> about phone. It shows Battery Status : Not Charging.

You get that when the phone is running normally? I think for me that one only shows up when I put it in bootloader mode. In MTP mode it's just a media device like any other AFAIK... I'll check tomorrow when I'm back on my Windows laptop to be sure . Have you tried putting it in PTP mode? If so do you see the device as a camera or is it the same issue?

Basically the way the Nexus One talked to other systems through USB is completely different from the way the Galaxy Nexus does. The GN uses a new protocol called MTP. Your car stereo probably can't read the files on your phone because it doesn't have MTP support.
Phantom Charging Issue
So I've gone ahead and Fiddled around with my phone for the past day trying to fix my USB issue, and I've discovered that this issue may not be due to USB issues.
Throughout the day when i was playing around and trying to fix my USB recognizing issue, it miraculously started working again. Now I am able to connect to my PCs and transfer the desired files.
Upon this issue being resolved, i noticed that periodically the screen would turn on, on it's own while being off in the locked state. I observed this issue to see what may be causing this, and it is turning on due to my phone thinking that i plugged my micro USB cable in to charge it. The charging indicator on the batter flips on, and even the USB Debugger / MTP Notification is present in the notification drawer.
Apparently this is a known issue with the Battery or charging port with Gnex's. (See below the 2 youtube clips for more details for problem/fix.)

I believe my warranty is void since this phone was purchased in a different country and has had the bootload locked/unlocked a million times. Anyone else have this problem that they have been able to fix manually? Or am I going to have to cross my fingers, ship my phone to get it fixed, and hope the post man doesn't f**k up?

Device can no longer see computers, need some help figuring things out.

Ok, first off I chose Sprint because I believe that Boost Mobile is on the sprint network, but my phone doesn't specifically say sprint on it or anything, so I had no clue which of these device boards to post into. This is the exact page I got it on, if that helps. [link deleted - paranoid forum rules] - I will post specs of the device in a minute.
Alright, the issue with my phone, is that after I used a car charger 2 months after I got my phone, it suddenly stopped being able to connect to ANY computer ever again. I suspected it was PDA net at first cause that was the newest change I had done to my phone. So, a few days later, I could find now way whatsoever to fix it, and had to factory reset. This fixed my phone just fine.
Two months later, I was fed up with having battery issues all the time, this phone drains battery faster than my laptop, and its battery is 3.8 years old! I got an external battery that holds 20,000 mAh/74 Wh (Practically the same as my laptop battery too. ) that is from the LimeFuel company. I know that before I used it, my phone worked with my laptop just fine. I don't plug my phone in to my laptop all that often, especially now that I have a battery to use with it. However, I download large files on my phone with 4G to put onto my laptop because my home net is crappy, so a week after, I noticed that my phone lost the ability to communicate with computers, again. I then realized, it had to be the connections. The first time it happened was when I used a car charger, the second time, an external battery. Each time, my phone suddenly inexplicably lost the ability to communicate with a computer ever again. It can only see devices as a power source, nothing more. There's no missing software or drivers, it just doesn't register as anything to my computer. Like a power toggle so it can't tell the computer "Hey, I'm a device that you can transfer data with".
One more note; The first time this happened, I had activated developer options but had them turned off. I mean that I used USB Debugging mode once and turned all of that off. The second time, I hadn't even unhid the option yet, unhid after my phone broke again to try and fix but nope.
I did research on trying to fix it, without factory reset because a factory reset is USELESS, if it's going to happen every single time I use anything but the wall to charge it, right?
There was a topic online claiming that there is a menu under "Storage" in the settings. There isn't. It was a big fat lie. Or Android devs deleted it.
There was another topic, claiming that USB settings would be under some wireless and networks area. Nope.
Now, I remember that when my device would connect to the computer, it would let me change it from MTP to PTP, but after this happened, nothing. It doesn't even pop up anymore, nor does it ask. There is no where in the phone that these options even exist at all. It's like Android devs deleted access to these options for no reason whatsoever.
Another bit in that topic mentioned ‘USB Mass Storage’, which also doesn't exist. Here's the topic with everything I tried, if I'm allowed to give links at all. If not, well not my fault. Topics used to try and diagnose and fix issues, but failed;

First off, after the factory reset and everything worked did you reinstall the pdanet?
Second, 20,000mah battery? Holy cow im jealous!
Forgive me if you have already tried these things but this is what i would do...
Did you reenable developer options and reenable adb debugging?
Did you uninstall and reinstall your phone drivers?
Is there an updated phone driver?
Have you tried a different usb cord?
Is there excess dirt or dust in usb charge port on your phone?
Does your usb charge port even work anymore or do you just charge external battery on wall?
Have you tried a different usb port on the computer?
Have you tried on another computer?
Have you tried updating computer drivers?
Have you enabled a fast charge tweak like on a kernel tweak app?
If none of these questions fix it then a workaround is downloading app called airdroid. You can wirelessly transfer files from phone to computer and back again without usb cord.
Let me know what worked please! Good luck!

1. No, I never touched PDA net again.
2. Too bad forum rules say I can't be friendly and give you the link to it.
3. Read the topic you quoted. I did, only after my phone broke again. Except it's not adb debugging, it's USB debugging. Doesn't work, because the phone can't communicate with a computer anymore.
4. 5. 11. Yes I reinstalled drivers and no there were no updates.
6. 7. Nothing's wrong with the cable. I did try with others.
8. What does that even mean? Yes my phone's port works. Nothing's wrong with any hardware.
9. 10. I've tried different ports and different computers.
12. Can't, phone isn't rooted.
13. I'm not using this. My phone is not there for Google/Android to tell me I'm not allowed to use my USB port ever again. I'm also not going to wait 4 hours for a 4 GB file to transfer via my router to my computer nor am I installing some app software to my computer just to have wireless transfer. This is not a work around. This is an "Oh well, it's broken, guess you can't ever use USB ports again for data access!"
note; I tried all of these (except 12/13) before I ever came here looking for help.
2. I will google it
3. I didnt realize toggle to turn on usb debugging didnt work sorry. I just know it needs to be on for the computer to see the phone. This seems to be an area of problem possibly.
8. Lol! What i meant was did the area where u insert charger function properly. Only reason i asked is because some of those batteries charge on wall unit made specifically to charge the battery only not with charge.
12. Doesnt require root for basic settings like changing governor usually. Only to overclock/undervolt, etc.
13. Great answer! But i meant as a temporary fix until someone more experienced with this issue helps you.
I also figured listing all those things would help other people see what you had and hadnt tried before asking you next time. Wish i couldve helped more. Good luck

2. amazon dot com /External-20000mAh-Limefuel-LP200X-Flashlight/dp/B00OHZVN5U/ - It let me charge my phone 7-8 times fully before it was empty. Automatically stops when your phone is full.
3. USB debugging doesn't need to be on in order for a phone to communicate with a computer. This is only if you want to debug apps or use other developer tools. File transfer works just fine without it.
8. I still don't understand what you mean. My phone is not broken in any way. Nor is my battery. My external battery charges off any USB input, my phone charges off any USB input. My phone just can't communicate data wise between devices anymore via USB.
12. Fast charge isn't going to fix my phone. Unless it disables data communication, then I need to turn it off. All "kernal tweak apps" appear to require root. The top 5 google searches shown this.
3. Wasnt sure. Ive always had it on
8. Some aftermarket batteries dont charge while in phone hooked up to charger. They come out of phone and into specialized charger for battery only not phone with it, so that it can charge the larger battery in a matter ofan hour or so is what i have been trying to say. But its obvious thats not the case for you now since i asked and clarified. If this was the case one might not know that the small usb port on their phone needed cleaning to make a good connection because they literally dont use it to charge their phone. They charge their phone with external battery charger. You see?
12. On my custom rom and on my trickstermod app it does say fast charge disables data communication and that you have to turn it off for computer to recognize phone again. This fast charge mode only works when connected to computer not wall charger it says
Wish i could be more help but im out of ideas. Good luck
Update to the current situation.
My phone is somehow, repaired. But I have no clue why. I did several things today, just screwing around while I backed up my stuff to the SD card. One of them could have fixed it, or my phone is magic and self repairs after a while. Lets list everything I can remember that I did.
1. I typed in *#9900# in my dialing app. Toggled an option called "Low battery dump" to "on".
2. I deleted a whole bunch of files, including hidden files on the internal storage. Probably screwed up my apps but, whatever, it works now.
3. I pulled the SD card out.
Shortly after all these things, I plugged it in for power, and it finally, got my computer to see it as an MTP device again. No clue which of these succeeded. I'm going to wait a small bit before I test the things that tend to break it.
The magic option, is because I tried to root, it broke, stuck in download mode with some error about firmware. For 4 hours it was stuck like this, I tried everything I could think of, which wasn't much, tried installing the ROM back too, after wasting 2 gigs of bandwidth downloading it only to get an error before it even started the install. Phone was still rebooting in download mode error screen. Left it sit there off for like a minute and it just turns it's self back on, flickers a few times and the logo pops up and the device pops on like nothing had ever happened to it. I'm so confused. :/ At least everything's back to normal. Now add a good confusion post icon below so I can click it and post. :|

this was your problem remember? fast charge does disable data communication.

Except, I don't have a fast charge option anywhere. I can't toggle fast charge. My phone is unrooted and locked and such. If plugging in a device like a battery or a car charger, toggles this option and the OS developers deleted access to toggle this option, it is an OS bug and a critical issue in the device that needs to be fixed. I don't know what fixed it, but I'm assuming it was the low battery dump, and that doesn't appear to have anything to do with fast charge and it was a hidden secret option in the system.

The way u said it i misunderstood i thought u did have it on. Its not an option on all roms though. Mine has it and i tried it and couldnt see files thru usb until i toggled it off so it was just an idea. I dont know the effects of the low battery dump off top of my head but i will remember that if i hear someone else with same problem. Glad its fixed now

[Need Help] G960F not charging, But OTG Works.

Hi,
My Galaxy S9 (Exynos) just stopped charging today. It had no problem this morning, but when I tried recharging in the evening, it won't charge at all. Connecting it to PC won't work either. But OTG works just fine. I am wondering if it is a hardware or software problem.
I unfortunately do not own a wireless charger so its almost dead now. If I could confirm it's a hardware problem, I would just buy another charging board but I would like to confirm it first before buying. Is this a common problem in s9? Could there be any issue on the software level?
Any help is appreciated. Thank you.

the only things that come to mind that could cause this is the board being bad or the kernel being corrupt. If you can OTG, you should be able to Odin with it (key word there is should), if you can Odin with it, just flash the HOME_CSC firmware files and if it charges afterwards, then you know it was the kernel. If it still doesnt work, bad charging port/card
Thank you for your response, but as I have said, my PC cannot charge it or even detect it at all. OTG is the only thing that works. Maybe the phone is blocking any data transfer when power come along on the usb port? Am I making any sense?

you are making sense, but if the OTG works, then data transfer should be working too. Can you boot to DL mode?

Yes I can boot to dl mode and recovery too. When I connect it to PC, the PC don't even make any sound (you know that usb connect sound).

I tried going to dl mode again and noticed that I can only boot to the warning screen, and then the volume button stops functioning there. Volume buttons works normally in recovery and OS. And also, I borrowed my friend's wireless charger and it was able to charge just fine with it.

I apologise for quoting you again and again, but I just wanted to update you that my Bixby button was stuck which made the volume buttons not working in the warning screen. I tore down the phone, fixed the bixby button and now I can boot to dl mode. And good news, Odin can detect the phone in dl mode. I will flash as you suggested and report back. Thanks a ton

youre most welcome! im glad you found the culprit because i wouldnt have ever thought of that. Situations like these are good in that they show examples of how weird stuff can get from time to time lol
if the phone is recognized by Odin and youre able to get to DL mode now, you should be all set

So, I downloaded the firmware, did a complete wipe with the csc file. Annnd bad news, it still won't charge I just gonna buy a new charging board.
I wonder why the usb works only in download mode though, still give me doubts that the charging board is the culprit. :laugh: anyway thanks for helping.
Hey, I faced a similar problem today, what was your solution to fix it?
I got the screen on my S9 replaced and now it won't charge... usually. I took it back to the shop and they got it to charge with a different cable. I tried a different cable at home and it worked for a while, but now it's not charging again. So annoying and confusing.
I am going to write how it went since there are people asking. Maybe will be helpful or not helpful for people who stumble across this thread in the future too.
So, I gave up trying to fix it and bought a new charging board, it worked for a day and then it stopped working again. I am pretty sure even the original charging board was just fine. I think the whole issue had something to do with Samsung's security or self-protection system.
I will not buy Samsung again. Thanks.
