Reading Internal SD Card Information CID.
Micro SD CID Reader Description
The App show you CID numbers of all installed storage devices.
@Android 7+ Users: CID File read access is restricted by many devices.
@DownVoters:
This App is free and written in hope to help users. I can't test it on all possible devices! If it don't works on your device and you are one from hundreds, maybe it's manufacturer dependent. And if you votes therefore with one star, it's not fairly!
