It looks like Googles next Android OS M will check your operating system and give you warnings on start-up to advise if your operating system is deemed unsafe or if it has code running from an untrusted source.

Whilst this will probably appear on Nexus based Roms first, it is worth noting that with Android M google are really looking to up security levels.

The OS will probably display one of the following warning messages to let you know that there could be a problem with your operating system.

yellow warning

This warning lets you know that your device has a different operating system than the one that originally came on your device, depending on whether you changed the OS (If you aren’t sure, you probably didn’t), if you choose to instal a different Rom you can continue to use your device with that operating system.

If however you did not install the different OS you can still continue to use it but google advise that you may have a better experience with the original OS, they also advise that you can contact the device manufacturers support centre for help restoring to the original OS.

amber warning

This warning lets you know that your device is in an “unlocked” state, meaning that your operating system can’t be checked to make sure that it’s safe to use.

Depending on whether you changed the OS (If you aren’t sure, you probably didn’t), if you choose to instal a different Rom you can continue to use your device with that operating system.

If you unlocked your boot loader you can continue to use your device, however, you acknowledge that your device may be exposed to security risks.

Google recommend that if you aren’t making changes to the OS regularly,  to improve security you should lock the device by running fastboot lock.

red warning

This warning lets you know that the operating system on your device has been changed or corrupted and is not safe to use, the device may not work properly and could expose your data to corruption and security risks.

Depending on whether you changed the OS (If you aren’t sure, you probably didn’t), if you choose to instal a different Rom you can continue to use your device, however, you acknowledge that your device may be exposed to security risks.

If you did not change the OS you should not use the device in its current state, Google advise that you should contact the device manufacturers support centre for help restoring to the original OS.

If you choose to ignore the warning messages should go away on their own after about 10 seconds and your device will continue starting up, however if you still see the warning message, you can choose to continue starting up your device by pressing the power button once.

If you’re not comfortable continuing to use the device, you can turn it off by pressing and holding the power button until your device turns off. You can contact the device’s manufacturer for help restoring the original operating system.

What do you think, are you a constant Rom swapper? or do you prefer to stick with original manufacturer roms? is the added security that this may bring worth the annoyance at boot up? or will you be looking for a rom and boot loader for your phone that has been coded to work around this?

Personally I like to try out new roms fairly often and have been impressed with the way rom devs over at XDA have managed to work around Samsungs Knox to enable custom Roms with out flagging up on boot, lets see how they get on with this should it become mainstream with Android M.
