I'm thinking to buy a new mobile phone, but I'm sure that it won't be Samsung.
I too had this especially more through the night when my phone was in sleepmode! If you have a custom rom like I do (Omega 42) I decided to start experimenting in flashing different kernels including stock original and the one I came across was Perseus alpha 32, I flashed that and now have no more mounting/ unmounting errors showing up on SD card monitor app as well as on my phone. It sounds like a mixture between Sandisk cards and the kernel to me.
Hope this helps.
Well it happened again. first the gs3 destroid my 64 gb sd card. now it killed my 32 gb card. they last less than a month on it.
soo good to spend money with sd card like this,,,,so happy....
Anyone heard of problems like this ? i'm so angry now i can barely think....
just lost my pacience and broke the damm card. have to control myself not to throw the gs3 on the wall...
