One of the most common problems of Android phones is low internal memory. Most of the low-end Android devices have only 190 MB of internal memory. After installing some apps, you will get a notification which shows that your internal memory is getting low.
You can get rid of this notification by using a MOD : Darktremor A2SD. It basically transfers some parts of the App to the SD card partition thus saving your internal memory. Link2Sd does the same thing. However it doesn’t work on all devices, so Darktremor A2SD can be used as an alternative.
