Ladies and gentlemen, I have already written a subject for the purpose of restoring the porflain after deleting all the data from the telephone.  This is why I will ask you here

In order to extract bitcoin, I first have to dump all the physical memory from my phone and then run applications to recover lost data on it? ( it was years ago and app from google store - bitcoin wallet / galaxy-s4)
If so, which application will be safe? or maybe i should do it manually according to a guidebook?
