I could imagine, you're on the wrong track.
Android phones (with their linux cores) would mount a card read-only if
they could not repair the filesystem after an inconsitency (and thereby they
would show the behaviour you observed) ... wether or not you could format them
in this state, is a question of the software used ... physically it should be
possible.
If a windows-phone behaves the same is out of scope of my experience.
But I can assure you, the number of write-cycles (reads do not harm) might be
limited ... normal use in a phone will not wear a card out that much that you
could notice it. All cards use wear-leveling and also have a certain amount
of extra cells that are being used when other cells die ... with that, you should
not experience errors due to "excessive" amounts of writes when used in a smartphone.
