Samsung has applied for a new trademark with the EU intellectual property office (EUIPO): Activate Fan Mode. Given that it falls into a category encompassing smartphones and tablets, it does sound like a switch for a relevant form of cooling found in the UI of a next-gen mobile device.
Physical spinning fans are not exactly news in the Android world: they have been pioneered by the Nubia gaming brand RedMagic for its flagship line of phones, and have also been adopted by Lenovo for its latest Legion Phone Duel. Samsung's potential own-brand version of the same also does chime with the No Fan Mode found in the Galaxy Book Pro.
Now, it seems this kind of hardware may be coming to Galaxy-series devices soon. Samsung has gotten serious about thermal management in its own flagship S-line phones as of late, which has proved particularly necessary with the advent of the Snapdragon 888 processor. Its new trademark may thus serve as a hint that its successors may drive OEMs to further cooling extremes.
