How to Choose best microSD card for your Android phone.

You have to be very selective when it comes to selecting the right SD card your device. As some SD card will support your Android phones or Tablet while some may not detect. Today I am going to share some tips which many of the tech savy friends out there know it, when it comes to a selection of SDHC and SDXC, or a Class 10 and UHS-I Class 1.

Tips for choosing the best SD card for your device.


  • Capacity of SD Card

When we have to select a SD card we often come across two varieties of microSD cards.

SDHC microSD cards & SDXC microSD cards.

The difference between the 2 cards are its capacity for storage.

  • SDHC capacity ranges from 2GB to 32GB
  • SDXC capacity ranges from 32GB to 2TB.

You’ll most often come across two types of microSD cards — SDHC and SDXC. The difference between the two is the range in capacities they provide.

However the number of files stored in a particular SD card can be determined by size of a particular image, mp3 or video saved in the SD card.

For example : Photo take from a high megapixel camera like 16 megapixel will have a image size of 7 mb that means 32GB card, you could store 4,500 or more photos on it. (This number would differ incase of Galaxy S7, which can shoot in RAW format, creating photos with much larger file sizes.)

Also note while purchasing a higher capacity SD card it is advisable for you to check whether you device supports high capacity SD card. This information will be mentioned on your phone broacher or can get this info online.



  • Speed of SD card

Other factor which you need to check while buying an micro SD card is to choose its speed to write data.
