A+. Has the three ID's I needed: Android ID/ GSF ID / Hardware Serial. Note that the third one is especially important for TWRP!
Simple fast download Downloaded it from Google apps on my computer and within a second it was on my phone with all the. Correct info
Does what it says. Would like to be able to change device ID for Wi-Fi connection to router.
Excellent Gives the hardware serial, which many similar apps do not. We need that for Gear VR development. Nice UI too.
Works just like it should! Need i say more?
Work's great Its a necessity tool for every experienced smartphone handler.
[Added] Support for latest Android 5.1
We are looking forward to implement QR code feature in future
Minimum requirement is Android 4.0+, old version still can be download on device running on 2.3
For paranoid users, you can get Device ID without Internet permission, read the app description for more info/link.
