A+. Has the three ID's I needed: Android ID/ GSF ID / Hardware Serial. Note that the third one is especially important for TWRP!
Excellent Gives the hardware serial, which many similar apps do not. We need that for Gear VR development. Nice UI too.
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.
Would be nice to be able to copy the Wi-Fi MAC Address without the ":" instantly as my university requires without.
Love it. Does 1 thing and does it best.
[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.
