This is a nice article, but i think it is a subset (not a copy i believe) of info from another source - link, which i was read recently.
Since i bricked my phone recently (few weeks ago. Thank god, my required files were already backed up to Google and Mi cloud); i was trying to prep up for a future issue, and in case I needed more cloud storage i.e. more than 15 GB, I'll go with Mega and Media fire in future.
