Different brands of Android phones try to differentiate themselves by their physical product design mostly (e.g. screen size, buttons’ placement and camera placement). Some will try to sell their Android themes’ ease of use. Others try to sell the camera and security features.

Basic things to check

While the above may be things that people really want, the underlying tech specs are the most basic things that we need to check are (which many people tend to ignore because of their bad technical understanding) :

  1. If you do not install new applications often and will usually use the phone as it is being packaged, you will probably need the following:
    – Up to 4GB of RAM
    – 64GB of memory space
    – 3100 mAh of battery capacity
  2. If you install new applications from time to time, you will probably need the following configuration:
    – 6GB of RAM and above
    – 128GB of memory space and above
    – 4000 mAh of battery capacity


Advanced things to check

Other optional things that you may wish to check are as follows:

  1. Sensors 
    – Fingerprint
    – accelerometer
    – gyro
    – compass
  2. Communications
    – GPS
    – Bluetooth
    – WiFi
    – NFC
  3.  Android version
    Are you using the latest version of Android on your phone?
  4. SIM card
    Do you need to use 1 or 2 sim cards in your phone?  Most people tend to say that they need 1 sim card only.  However for those who travel overseas often, the second sim card is useful for using pre-paid sim cards mainly for cheaper mobile internet usage, and it is hassle-free to switch between the two sim cards.
  5. Camera
    Many people tend to compare by the number of megapixels the phone can have.  But in actual fact, you only need the following for a good 300pixels/inch printing resolution:
    – 3.2 megapixels for 5R photo (5×7 inches of print size)
    – 16.2 megapixels for 12R photo (12×15 inches of print size)
    – 19.5 megapixels for 512R photo (12×18 inches of print size)The idea here is that we simply want the best of the best, but that will also be compromising our memory space while we cannot utilise its full potential on the screen as well as on the photo printouts.

    What we should really be worried about is the following:
    – 1 camera in front, and another 1 camera at the back.
    – Capability to take good night photos.
    – Capability to take vibrant looking photos (a combination of lens and software capability)
    – Capability of saving RAW formats if you wish.
    – Capability of configuring ISO, aperture and others.

  6. Sound
    – Do you need your 3.5mm jack for your earphones?
    – Speaker quality
    – Bluetooth capability for earphones
    – Does your earphone have a mic for answering phone calls?
  7. Screen
    Do you need a large screen?  In terms of your touch screen, do you need to use a stylus pen other than just hand touching?
