Answer 1

Find ".android secure" file under SD Card catalogue or connect your phone to the computer. You will find a file named "smdl2tmp1.asec" or something else. In short, delete the files that have different format with the normal application one. Then, install it again. Or, you can also delete "/mnt/secure/asec/smdl2tmp1.asec" with the terminal virtual machine and install it again.

Answer 2

Problem was solved by formatting microSD to exFAT file system. Phone at last recognize it and propose format it. After formatting it became work!
