This is a well discussed and easy to fix bug... Disconnect USB cable, go to Settings, Apps, and Show System Apps and find External Storage and Media Storage and clear data and cache on each one and reboot, then give it 5 min after full boot up to rebuild media databases and connect to USB and select MTP. Should be good to go. EDIT: In some instances where ...

In order to assign a drive letter to a removable device, that device must support UMS (USB Mass Storage) protocol. Unfortunately most newer Android phones, especially those without a removable SD Card, do not support UMS. Instead, they support MTP (Media Transfer Protocol) and PTP (Picture Transfer Protocol) protocols. In such devices it's not possible to ...

You can swipe down the Notificationbar and it will show Charging only. If you click that entry you can select the desired mode. The selected mode won't be set as default, so if you plug your device again, it will be on Charging only again. To set the default mode you first need to enable developer mode (don't ask me why...). This can be done by going to ...

1. first check your usb cable a. your cable could be a "charging only" cable (i.e. only has wires to carry power and no data wires) This cable could be a charging-only cable, which doesn't include the D+ & D- cable streams. If you're unsure on the type of cable, try using a different cable that you're sure works. b. if you are using usb-3, it could be ...

Go into Developer options, and cycle the USB host mode, the files will show up on my PC.

I'm not 100% sure. But IIRC, the problem with normal USB storage is Android has to partition your phone for internal storage and USB storage. Your computer can then umount the USB storage from phone and mount it in your computer. So in many phones without MTP, even though the internal storage had capacity like 16GB, only 1 or 2 GB was available for app ...

Yes and no. The fact that your Galaxy S3 does not support mass storage mode means that you cannot play audio files stored on the S3 with the radio, like you could with a USB stick. (If your car's radio supports mass storage, that is.) However, the other type of USB connection, allowing your iPhone to be controlled by your car's radio is an Apple Accessory ...

Answer With Android 4.0 ICS, charge only mode is no longer available. Unfortunately there's no app to deal with this issue AFAIK. You can try, but I believe that this isn't possible with your phone, but for future readers, placing the phone in "media transfer mode", allows access to SD cards on both phone and computer. Further into this matter One can ...

First of all you don't need any USB cable. You can transfer files from/to your android device with the Wi-Fi network of your device. Just install airdroid on your android device. Then activate wi-fi hotspot on your android and open the airdroid app. Next connect your pc to that hotspot, open any browser in your pc and enter the url provided by the airdroid ...

USB Mode: Set Default to MTP (file transfer) Marshmallow/6.0 Default is set to Charge only mode, You can enable developer options and enable MTP feature by following below steps: Settings -> About phone -> Touch 7 times on Build Number to enable Developer options Settings -> Developer Options -> Select USB Configuration -> MTP

After about 4 hours of installing drivers, wiping data & cache of apps, wiping cache partition, etc... I found the solution was just to change USB option from 'MTP' to Charging while USB was connected to the computer, then while still connected, change the USB option back to MTP once more, voila! Edit: How to find the USB options may vary between ...

I just had the same problem tonight. All of a sudden my pc wouldn't recognize my S3 when I connected via the USB. I tried the USB debugging first and restarting...didn't work. I popped the battery out and restarted, and the USB icon showed up. Hope that helps. Thanks for all the helpful troubleshooting ;)

Enable USB debugging: Go to phone settings -> About -> Tap build number repeatedly until developer menu is enabled. Go there and tick USB debugging. On your PC, go to your device manager (You can find it in Control Panel, System) when the Phone is plugged in and set to MTP. Locate the phone, (it might come up as "Android Phone" if so open the tree a level. ...

The possible solutions are Download Motorola driver Goto Device Manager and right click on the motorola device name and select uninstall Now right click and select Scan Hardware Change Now select Update Driver Software and click browse and point to the downloaded ...

As you said, it's possible only if your device is rooted.. Google no longer supports USB Mass Storage Mode due to several reasons, since JellyBean. However, there are softwares for PC that virtually shows & provides access to the device (connected in MTP mode) as a Removable Storage USB Drive, like for example, MTPdrive (as @beeshyams commented); no ...

If you enable USB debugging in the Developer options, the phone's "USB Connected!" screen doesn't popup anymore :)

The USB spec specifies that the power supplied over USB shall be ~5V DC, which is fine. A single USB device (e.g. your tablet) may draw up to 500 mA of power in USB 2 and 900 mA of power in USB 3. This is the issue - it's workable but not ideal. Using a USB cable as a power connector between a tablet and the AC adapter that came with the tablet is a ...

This feature is called "fast charge", and it charges your device slightly faster by disabling the USB data capability. It's not available in the stock ROM that I know of, so you need a ROM and a kernel that you know supports this. I'm using AOKP with the Franco kernel and it works great on my Galaxy Nexus, so you could try that. (There's even a quick toggle ...

Funny thing is: Blowing into the phones USB solved the problem for me. Maybe you try that =D

Summing up from the comments above... As eldarerathis wrote: "connected as a media device" suggests it's using MTP, which would require special software to be installed (there are MTP packages available for different Linux flavours). Try getting UMS working You might also want to check your "notification area" when the device is connected: I don't know ...

Google changed the USB protocol for Marshmallow to always default to charge. The reason for this change because they brought back the ability to make external storage (SD card) become internal storage. Creating a new storage type called "Adoptable Storage". Originally google removed the ability to swap storages because they viewed it as a huge security ...

The Default mode for Android USB Transfer is MTP (Media Transfer Protocol), which isn't supported by Mac. Apple’s Mac OS X is a holdout — it doesn’t include MTP support at all. Apple’s iPod, iPhone, and iPad use their own proprietary syncing protocol along with iTunes, so why would they want to support a competing protocol? Google provides an ...

Ok, so I had a look at this thread and, as it suggests, I took the microSD out and put it back in again. Now it works as before. Smells like a bug to me?

XDA developer capslock66 has developed a reverse tethering tool which is the simplest yet (and hopefully in future too). Only requirement is a rooted phone. You can download it from here- Android reverse tethering via usb It comes as a zip file with all the adb files and dependencies. Once you open the application, it will do all the settings on your phone ...

Finally found an answer: it's not possible. Samsung implementation of MTP works incorrectly so device cannot be used in standard tools like GMTP. Moreover, MTP application on the phone crashes sometimes during data transfer.

Unfortunately, it's a big problem. Google apparently decided to go MTP only route since it does not require unmounting the storage from the Android side when you connect it to your computer. So: You cannot assign a drive letter to an MTP device. Here's my answer on superuser.com explaining why. There is a program named Alt Mounter that supposely solves this ...

Here's what worked for me. I don't know what caused it, but I suspected an Exchange server policy triggered it. I deleted those accounts just in case. Then I rebooted into recovery mode (volume up + home held down at boot). From the recovery menu, I wiped the cache partition. When it came back up, it saw the USB connection just fine again.

Starting in 4.0 (actually 3.0, but few devices used that), most Android devices use the MTP (Media Transfer Protocol) class rather than the Mass Storage class. This was done for various reasons, including the annoyances attendant to having to unmount the SD card from the Android device to access it from the PC. Samsung has embraced this new way rather ...
