In the last month I noticed that more and more files on the internal data partition of my Android phone are broken. The files cannot be read via MTP and are empty when opened on the phone itself (e.g. grey pictures). As the number of "new" broken files increases I think that a part of the flash memory is broken.
1st: Is that a possible explanation? I would have expected flash controllers to hide broken cells automatically?!
2nd: Can I manually mark those sectors as bad sectors?
3rd: SATA-SSDs show how weared-down they are via SMART reporting - is there a way to check the quality of the flash cells within an android device?
