Did you know that the average person unlocks their phone 100 times a day? It is true, and unlike many stats coming from limited data sets, this piece of information comes from the best source for such stats: Google itself.
In a leaked slide from a presentation for Google employees pitching the new Nexus phones, Google mentions this interesting and round number.
The new fingerprint scanner in 2015 Nexus phones will make unlocking your phone faster
The context of the mention is the new fingerprint scanner used in the Nexus 5X and Nexus 6P: it is novel in the way that it allegedly does not require you to first unlock the screen and then use it - a single tap on the reader will unlock the phone with no additional steps required. So far, Huawei is the only phone maker that we know of to use the same fast unlock method, while Samsung and Apple both require you to first unlock the screen before you are allowed to unlock via a fingerprint scanner.
Interestingly, you can check how many times on average you unlock your phone in a simple way: just download one of the multiple unlock counters from the Google Play Store or Apple's App Store. How much do you get?
