Hi friends i want to increase inbuilt memory at infinity level by replacing Emmc holder (inbuilt memory card mounter) with external memory card mounter, can it be possible? If yes how? If NO Why??
There's more to just internal storage in eMMC - it holds a vast array of partitions. Here's an example I just got from my phone.
As you can see many of those "blocks" (mmcblk_p_) correspond to major functions of the phone. Even more, such as EFS (stores baseband info) and sbl* (bootloader) aren't even listed here because they're even more crucial, are loaded at boot time, and doesn't allow a regular user to tinker with.
Now imagine all those partitions all shifted to an external, removable source. With proprietary formats, is it possible in the first place? Even if yes, what if one removes the media in the middle of booting up?
And lastly, eMMCs (and recently-introduced UFS2s) are significantly faster than your average SD card. Running Android on a Class 4 SD card is actually a painful experience - if you don't believe it, burn Android-x86 onto an SD card and try booting from it.
