How to stop images from showing up in Android Gallery?

Application stores pictures at their respective photos, and we download "photos" and keep it for ourselves. But Android Gallery searches and indexes those pictures/photos on the entire SD automatic, and shows them in the Gallery. This can be an embarrass to us sometimes.

How can we stop the images at certain folders from showing up in Android Gallery?

If you like to hide an individual files from the gallery, just rename the file of the picture/photo with a . prefix.

If you would like to hide an entire directory that keeps yours images, just create an empty file with the file name .nomedia in the same folder.

Full ROM Backup on Unknown Tablet

This is a quick way to perform full ROM backup on tablets. Since those are unknown brand, I have no idea how to "root" them and perform full backup as usual.

Here's how to perform the full ROM backup and restoration on 2 identical (same brand) tablets. (Model M716D running JB 4.0.1)

[ To Backup ]
Start your tablet
Connect the USB cable to tablet
Start command prompt/shell prompt

adb shell
root@android#/ stop zygote [ this one stops android ]
root@android#/ busybox tar -cvf /mnt/sdcard/full_backup.tar /data/*
root@android#/ reboot

[ To Restore ]
Start your tablet
Connect the USB cable to tablet
Start command prompt/shell prompt

adb shell
root@android#/ stop zygote [ this one stops android ]
root@android#/ rm -r /data/*
root@android#/ cd /data/
root@android#/ busybox tar -xvf /mnt/sdcard/full_backup.tar
root@android#/ reboot

[ My Experiment ]

• Make full backup on tablet-1.
• Before reboot, I quit the shell and make a copy to my computer.

1. exit
2. adb pull /mnt/sdcard/full_backup.tar
3. ren full_backup.tar full_backup1.tar
4. adb shell reboot

• After reboot, I start to install games from Play Store.
• Then I try the method above to restore the tablet-1 back to original (first boot assistant). [ success ]
• Make full backup on tablet-2. [ just in case ]
• After reboot, I start to install games from Play Store to tablet-2.
• Before the restore tablet-2, I copy tablet-1's full_backup1.tar to tablet2.

1. adb push full_backup1.tar /mnt/sdcard/

• Then I try the method above to restore the tablet-2 back to original (first boot assistant) using the tablet-1 backup file. [ success ]

Wipe out/Factory Reset Samsung Android’s Phones

A major security vulnerability has been disclosed at the Ekoparty 2012 Security Conference which affects Samsung Android handsets.

It it is possible to reset those handsets to factory default settings and in the process wipe out all data. This vulnerability exploits a “secret” code (actually is USSD code) that can be used to trigger the factory reset automatically, without asking any confirmation from the user. That code is: *2767*3855#

There are different methods known to date to push that code onto those handsets:

• SMS in Wap Push mode (where the user would have to click on a link)
• QR Code
• NFC Protocol

Or… if users go to some websites where either

<frame src="tel:*2767*3855%23" />

or

<script>document.location="tel:*2767*3855%23";</script>

is contained in the HTML page.

So far, it has been confirmed to work against the Samsung Galaxy S3, the Galaxy Beam, S Advance, Galaxy Ace and Galaxy S II and some HTC devices.
