Most of the 3rd world lives with dumb phones that work well for the tasks they are designed to perform which are to make calls and send text messages. The device in question is not able to perform any of the above named tasks without running into problems. This would frustrate anyone no matter where they live
If the 'problems' are lag and failure to multitask (as listed) then they are only problems of patience, as I mentioned. This does not frustrate anyone; it frustrates folks who feel entitled to the best.
