install apps to external sd card,any android 4.2.1
My bro bought a micromax canvas 2 plus running 4.2.1 and asked me toh swap the sd cards..
At first i thought it would be easy since there are so many posts regarding this..but all the methods failed..
The twist is..there are 2 files in the system/etc folder..
So..replacing 0 with 1 in the vold.fstab file doesnot do the trick..
After many days of searching every where, i finally found a way..
1.Root your phone
Use root explorer( or any other file manager with root access)
2.navigate to system/ etc
3.now open the vold.fstab file as text
4.make a backup of the original file
Change the lines:
dev_mount sdcard /storage/sdcard0 emmc@fat/devices/platform/goldfish_mmc.0 /devices/platform/mtk-msdc.0/mmc_host
dev_mount sdcard2 /storage/sdcard1auto /devices/platform/goldfish_mmc.1 /devices/platform/mtk-msdc.1/mmc_host
dev_mount sdcard /storage/sdcard1 auto /devices/platform/goldfish_mmc.0 /devices/platform/mtk-msdc.1/mmc_host
dev_mount sdcard2 /storage/sdcard0 emmc@fat /devices/platform/goldfish_mmc.1 /devices/platform/mtk-msdc.0/mmc_host
In vold.fstab.nand change sdcard0 to sdcard1
Then reboot your phone
PLEASE NOTE: the above change will NOT show your external as internal..or vise versa
But all those large apps and games will get installed in external sd card..
Make the default write disk 'external sd' from settings
