Short Answer: Currently, you can't make use of your device (any device that relies on MTP) to act as an MSC, due to the protocol specifications! Elaborating As to clarify, Galaxy Nexus uses one massive partition for the entire device, it's like saying that: system, data and sdcard are all together. MTP was selected for Galaxy Nexus because it allows the use ...

The NFC feature does not sit in the battery, only the antenna does. NFC consists of: an integrated chip (soldered onto the logic board) an NFC Antenna that needs free view to the phone's back side (antenna signals from the sticker on the back of the battery only need to pass the back cover) If you look at the antenna you'll notice how big it is. It's ...

Beware: The instructions are for clean installing an OS. That means ALL YOUR DATA will be permanently LOST. If your phone was previously rooted it will be brought back to an unrooted state (whether you want it or not). Please, remember to make backups of any important data on your phone. It will be lost. 1. Turning on USB debuging Turn on USB debugging on ...

All phone (wall-type) chargers are voltage sources, i.e. the adapter provides a stable voltage output (5V here) and the device decides how much current to draw. Your charger's specification says it provides a maximum of 2Amps. That means it will sustain its 5V output voltage up to a current of 2A. The phone's internal charging chip may or may not charge the ...

I've had a little look at this now that Android 4.2 source is out. It turns out that HDR isn't done by the camera app itself, it's a scene mode that needs to be supported by the operating system implementation and/or drivers. The camera app will remove the HDR button if: You're not on API level 17 (Android 4.2) or above, or; Camera.Parameters....

The problem was bad (or improperly upgraded?) saved data in the launcher app. Here's how I fixed it. At the dialog above, press "Report" When in the report screen, drag down the notification bar at the top of the screen. Press the settings button in the upper left of the notifications area. Tap "Apps", then "All", then find Launcher in the list. Tap ...

You need to press the Vol Down and Power buttons together, and hold them for a second or so. Some users report that it works better if you press both buttons simultaneously, as opposed to one after the other in sequence.

Check the firmware version of your device: Open your favourite File Manager; Access the /system folder; Locate and open a file called build.prop; Find the line that starts with ro.product.name. Whatever comes after the equals sign =, that's the firmware you have. The different variants and their meaning: Below there's an updated list of the known ...

That screen means your device is in "download" mode, which allows it to be reflashed using Samsung's Odin utility (or the open source alternative Heimdall). It's accessed by holding the volume down button when powering on your Galaxy Nexus. Also, to clear up some confusion, this is not Fastboot mode - that is different. You access fastboot mode by holding ...

On the Samsung Galaxy Nexus, you can add the Android built-in "Power Control" widget to your screen, this has a one-click button for turning Wifi on and off on the left-hand end of the bar. (screen shot is from the home screen of my Galaxy Nexus, but this power bar has been built-in to Android since at least v1.6, though some manufacturer customizations do ...

AFAIK, the vibrator motor that are used in the phones are called Q-Coin motor as they are in a shape of a coin. They are of permanent magnet type accepting two leads for positive and negative DC voltages. The circuitry that operate this motor just can switch on the motor for a specific period of time and can change its rotation direction. All other ...

There are many variations of the Galaxy Nexus. Most likely, your phone is yakjuxw, which gets the updates from Samsung. The other phone is either yakju or takju, which use Google's own updates, which are released quicker. The versions are interchangeable, if you don't account for international customizations or possible carrier modifications. For example, ...

Grab this .apk file from the XDA forums and sideload it like you would any other app. The instructions state that it will work on unrooted devices, and CNET actually ran an article detailing this a little while back. The original XDA thread is here, the link you need is the one under the QR code (the "APK method"). This particular method will evidently only ...

Yes you have full 16GB for apps+data together in a single file system. You won't have to do any moving to SD card any more. Google merged both partitions. It's just one big file system now with sections for the former parts. It's completely transparent, so no worries for you. Formerly: /data and /sdcard were separate partitions Galaxy Nexus / Nexus 7 and ...

Go into Settings | Data usage. Then in the Mobile tab, you'll find a list of the applications that have recently used data. Click on any of these applications and there will be a checkbox to restrict background data while the phone is using a mobile connection (as opposed to wifi). I'm not aware of a way to control the sync frequency.

adbcontrol can do this. It opens a window containing the phone screen on your computer, so you can use it when the phone screen is broken, and you can click and type in the window to control the phone. To install adbcontrol do: wget http://marian.schedenig.name/wp-content/uploads/adbcontrol.zip unzip adbcontrol.zip Now edit config.properties and change: ...

The NFC circuitry itself is in the phone, but the antenna is in the battery. This is due to the layout of the phone. Since the range of NFC is very small, the antenna is placed on the outer side of the battery to increase the range as much as possible. Yes, the downside of this is that replacement batteries need to be NFC-enabled, but it's a small price to ...

I waited very impatiently for the JellyBean update for few days last week and finally did this to get JB on my Galaxy Nexus. Manually trigger the update by clearing the data in Google Services Framework and then check for System Update in Settings. You might have to do this multiple times though. I had to do it 5 times to get the update. You might be ...

The 1280x800 pixels count for the whole display, including the black bar for the buttons. Google decided to stay flexible by moving physical buttons to the touch screen permanently. Benefits: No capacitive buttons needed (cheaper?) Better user experience: Rotating 90,180,270 degrees rotates also the virtual buttons Less frame space (the button's space ...

It may be possible to export a loopbacked image file via USB as UMS/MSC. You will definitely need: root kernel support: loopback (/dev/block/loop0) and UMS (/sys/devices/platform/usb_mass_storage/) custom app to enable/disable this or a custom init script to always export the image file Here's an example for an easy hackable app, a little development ...

You actually can enable both of those features while in airplane mode. They get turned off automatically when you first enable airplane mode, but there's nothing that prevents you from re-enabling them:

The answer is simple: Do not close apps when possible! Android takes care of app managemnt by leaving them stick around (which is not necessary in memory) when possibile allowing faster startup times and resumption where you left. Swiping out a app of the recent app list is similar too closing it, but not the same.

Install a sensor app like AndroSens or AndroSensor. They both are able to show you the proximity information. Note: The sensor only distinguishes between near and far proximity (0-5cm and >=5cm usually). It is OK that you won't get accurate distance measurements.

This looks like it could be an issue with certain background services malfunctioning. Try observing the background services and disable some of them to see if you might hit the culprit.

Alternatively, my default recommendation for cases like this: Tasker. Use a profile like this (abstract): Condition: App (select "Youtube", and optionally other apps you would like to have autorotate turned on) Task: Display->Display Rotation: Set On This way, whenever one of the selected apps runs in foreground, autorotate is turned on -- and as soon as ...

All OTA updates reset file permissions, so you'll lose root unless you take special precautions. Install OTA RootKeeper and make a backup of your su executable before applying this update. You'll be able to restore your root once update is finished. Obviously, since this is an incremental update, you need to have a stock Nexus ROM. If you deleted or altered ...

I had the same problem: I bought my phone from Amazon.com and got stuck on 4.0.2 with no OTA upgrades. When I looked into it, it turned out that I was running a firmware (yakjujp) that was set to get updates from Samsung, as opposed to getting them directly from Google. First you need to determine if your device is receiving updates directly from Google, ...

From a developers point of view (my point of view): Application's on Android work a specific way, they all have their own life cycle, the main ones we are talking about here is when the application is paused, or stopped (onPause, onStop) and when the application is destroyed (onDestroy), these two states are brought to light in different ways, onPause is ...

My solution, which seems to be working so far, is quite related to what was proposed by t0mm13b. That proposal was to adjust the DHCP settings. However, my router is quite limited in functionality and it's impossible to adjust wifi settings on it. Insane, I know. So, I set my phone to use a static IP address instead of using DHCP. So far, so good.
