Android

 Logo description by SnowflakesOmega

Background : Android is the name of the mobile operating system made by Google. Debuted in 2008 with the T-Mobile market, later expanding through various electronic brands such as Samsung, LG, Motorola and HTC, the operating system then began to rise into the mainstream market during the 2010s. Android phones are based on the Linux kernel and has a large support of third party applications.

1st Logo (2008-2014?)

Logo : On a black background, we see the silver trademark text "ANDROID". The text shines continously.

FX/SFX : The text shining.

Music/Sounds : None.

Availability : Uncommon. It appears on various Android phones which may be running on a stock interface. Don't expect to find this easily on known brand phones (like Samsung, LG and a few others) since they replace this bootscreen with their own.

Scare Factor : None.

2nd Logo (2014-)

Logo: Same as before, but the text has changed font and is lowercase. The result looks like "android".

FX/SFX : The text shining.

Music/Sounds : Same as above.

Availability : Slightly rare. Appears on Android phones running versions after Android 4.4 KitKat on a stock interface. It also appears when Android x86 (LineageOS) starts up. Don't expect to find this easily on known brand phones (like Samsung, LG and a few others) since they replace this bootscreen and the previous one with their own.

Scare Factor : None.
