Option to disable search function in drop-down

search function is helpful on computers, but annoying on phones as it automatically opens keyboard which takes half of the screen and displace choices, if you want to navigate choices you have a little space on phones to do that, It will be helpful to put something like search icon next to the drop-down, if the user wants to search, he/she will click on it or make option to disable search function, otherwise it is too annoying on phones!
