Tips and Tricks for Samsung Galaxy Tab

We’ve been testing Samsung Galaxy Tab for a few months, here are some practical tricks that are not covered in the very limited printed documentations inside the box.  Geektechpost.com

Hotkey: Screen Capture
To make a screen capture of the device, press and hold the back button, and press the Power button once.  If successful, you will hear a camera shutter sound, and the toast message of “Screen Captured. Saved as image file.”

You can find the screen capture file at the folder called ScreenCapture under the root directory, with the file name “SCYYYYMMDD-HHMMSS.png”.  For example, “SC20110203-040506.png” means it is captured at 4:05:06 am, on 3 February 2011.

Note: This might not work on certain apps which have designated special function on the Back button.

Hotkey: Task Explorer

By pressing and holding the Home button, you will see the eight recently used apps, as long as a Task Manager function.  This is especially good to close unwanted apps on the fly.

 

Hotkey: Force power off
If something get unresponsive (for example you use Browser, Music player, several IMs simultaneously), and you can’t just end it by any normal mean, just press and hold the Power button for 7.5 seconds.  The power will be off and you can reboot afterwards.

Save energy, save the Earth
Like every other device, Wi-Fi and Bluetooth can consume a significant portion of battery even when idle.  Turn them off when not in use. 

 

How to change input method
A new user in Android handset might wonder how to change the input method (on-screen keyboard) during input. 

While most users might opt to use the default Swype keyboard or Samsung keyboard, users in East Asian countries usually need to switch input method several times a day.

Tap and hold the blank field and until you see the popup menu enabling you to choose input method.

MobFox vs AdMob

Early last month the CEO of MobFox (Julian Zehetmayr) sent to selected Android Developers an email inviting us to join their network, and we decided to give it a try in some of our Android Apps, and we are still using it.

 

 

If a click can only generate $0.03 per click, we tend to evade them – it’s better to display house ads than low-paid ads – at least they might download your free app and your potentially profit will be way more than 3 cents.  By default, their eCPM control function is off, and you will risk your program display low quality apps.

Turning the eCPM control is easy – just send them a notice by click a few simple buttons.  We are currently setting the minimum display threshold to $0.036.

As MobFox also supports backfill of advertisements, you don’t need to worry that no ads to display.  Simply put the AdMob or InMobi Site ID and you will get money generated from both side.  You don’t get to set the display rate though.  Out of my calculation, they are refreshing the ads at a 60-second rate.

Indeed we do enjoy a higher eCPM in MobFox than AdMob, but not as high as they claimed on their front page (it’s nowhere near triple eCPM – 200% at most).  Contrary to the widespread belief of a way higher CPC in ad revenue, in some territorial apps I only enjoy limited success (especially those in China.)   So it is really a territorial thing – it works well in Europe and perhaps America.  Just don’t use it in your Apps targeting Asia!

If you have something to ask, please do ask us.

We are planning to develop iOS apps for iPhone, iPad and iPod Touch.  We will definitely implement MobFox on apps that targets European users.
