What do screen resolutions mean?

Now that smartphones have evolved largely into touchscreen-centric multimedia devices, screen resolution and size have become some of the most important features. If the screen is too small or the resolution is too low, it can make the phone itself a hassle to use. Having a big screen is great, but it will look terrible if the resolution isn’t high enough.

Various resolutions have been created to help distinguish between each other, and here is a list of the most common ones you will find on Android powered devices:

  • QVGA (320×240) Used in small phones like the Motorola Charm
  • HVGA (480×320) Common in older devices like the HTC Hero
  • WVGA (800×480) The most common these days for phones like the Evo 4G
  • qHD (960×540) Used on high-end phones like the Atrix 4G
  • WSVGA (1024×600) Common for tablets like the OG Samsung Galaxy Tab
  • WXGA (1280×800) Used for the high-end tablets of today like the Motorola Xoom

Clearing application defaults

A great feature of Android is the ability to override many of the default applications for core features of the phones. You are free to pick Skyfire for browsing, DoubleTwist for music playing, and Handcent for text message sending. You can even use completely new launchers like LauncherPro or ADWLauncher. Doing this can leave you puzzled if you want to go back to using the “stock” services and we are here to help.

A built-in feature of Android is there for you in situations just like this. Go into Menu > Settings > Applications > Manage Applications and find the application whose defaults you want to remove. For instance: If you want to go back to your stock launcher after using LancherPro, find the LauncherPro app on the list and click on it. Scroll down a bit and click the “clear defaults” button and you will be set. Next time you do an action that you had set that app as the default for, Android will pop up a notification offering a list of apps that can be set as the default for that action. Select the “Use by default” check box, make your choice, and you are done.

sometimes  the device may start with ” login screen”  after you installed software,it casued because there is no space of roofs ,but we can enable  “usb host ” start before “login screen ”
How to enable USB Host mode automatically on startup

  • Open file /etc/rc.local in a text editor with root rights
  • Place below lines just before the last line exit 0

    • echo 1 > /sys/devices/platform/hhtech_gpio/usbpwr_en;
    echo 1 > /sys/devices/platform/hhtech_gpio/usbotgdrv_en;
    modprobe ohci-hcd;
    modprobe usb-storage;

  • Reboot

I tested this method and works fine on my SmartQ 5. My usb mouse automatically operates after boot.

One advantage of auto-enabling USB Host mode is that you can use a usb keyboard if you have a “login screen” situation.
