OS

I was surprised to see that the F116 Pro doesn't come with that many unwanted apps (only had to remove 3).

Instead, the OS has some features I haven't seen a lot in the past (if at all) starting with memory expansion.

The 120Hz IPS screen can be also be set at auto, 60Hz and 90Hz (this isn't something new but for a rugged phone this is the 2nd time I've seen it).

Gloves mode is very useful for people who work in specific industries (even bikers and low-temperature areas).

DuraSpeed is yet another useful feature FOSSiBOT smartphones come with which however I recommend turning off if you need on-time alerts from applications like Viber or Teams.

Call recording is a feature that has gone missing lately from many smartphones (even apps have been removed from play store) so this can also come in handy.
