There have been a few threads about this but none particular to my situation. I have an old Samsung Galaxy S4 that had some Bitcoin on a the Mycelium Wallet app in 2015. Something happened and the app got deleted, and after trying some basic recovery I chocked it up to the coins being lost. The phone has never been restored, the app just deleted, and after some research there seems to be a glimmer of hope that I can either use recovery software or find the private keys in the phone by getting root access. Is this possible?
