KARBONN A7* STAR MAKE YOUR 158 MB INTERNAL MEMORY TO 1GB TO INSTALL ALOT OF APPLICATION
• Remember you must need to have 4-16 GB sd card with class 4 or higher.
• This method has been tested by me on karbonn a7* (star) devices by using 16 GB class4 sd card
• First of all you need to do is "you have to make partition on your sd card".
• How to partition sd card am giving u Method and link here
Download MiniTool Partition Wizard link below
MiniTool Partition Wizard
Remove the SD card from your Android phone and connect it to your computer via a USB adapter or SD card-reader slot.
Copy any data you wish to preserve from the card to a file folder on your computer. Partitioning requires reformatting parts of the SD card and existing data will be deleted.
Launch MiniTool Partition Wizard and wait for the application to recognize and display your drives.
Right-click on the heading for your SD card and select "Delete." Any existing partition on your card and all data stored on the card will be deleted.
Click the "Create" button and select "Primary."
Select "File System: FAT" if your card's capacity is less than 1GB; select "File System: FAT32" if the card is 4GB or greater.
Select the amount of space you wish to allocate for regular file storage from the Partition Size menu, then click "OK" to close the menu.
Click "Create" again and select "Primary."
Choose "File System: ext2 or ext4. I choosed ext2" if you plan to use App2SD for app storage, or choose "File System: swap" if you plan to use a swap file to extend your Android's RAM using the card.
Click "Apply" when finished. None of the actions described above will occur until you click this button – MiniTool Partition Wizard queues actions to run in sequence instead of processing them when entered.
