When looking at the HTC U11 Life phone unlocked version on the HTC website, notice that a free back cover is included that frees up the sides of the phone to allows user to use that squeeze function which HTC touts as it's most distinguishable and desirable future? Well, also take notice that T-Mobile's version of this phone has conveniently left this out of the package so that it's purchasers will eagerly fork over another 30-40 dollars to put the phone in a third party Incipio or Griffin case which, unfortunately, makes the squeeze function very difficult to use.
