How to get setting information before booting Android devices like in BIOS? Is there any method by which we could get the system information before booting android OS.

Like wise in PC/laptop, we can get into BIOS setting before booting and get the system information. Do Android devices have such thing?

If yes, how can I go through before booting? Is there BIOS like setup in android? Shed some light.
There is no BIOS type thing in Android, although there is the Logcat and DMESG.

There is an app on Google Play that allows you to change your boot animation to show you the live logcat as your device boots.

If you want the System Info, as per your question, you would just have to Google your device, or use a site such as GSM Arena to lookup your devices hardware.
