Every waking day of every waking use of the devices I have, I find myself constantly fighting a lot with the shitty input and recognition of said input. Things I swore I clicked once but having to click twice or sometimes three times. Such lag input between the last time I clicked and to the time the function of whatever I had to click fucking functioned.
With phones it is obviously worse, with finger input being either too sensitive or too dulled to register, inquiring more touches just to get somewhere or to type something, along with the separated frustrations aside trying to type on awful keyboard interfaces.
Things never just worked all the time and I don’t expect they ever will.
My preference is that I don’t need perfection, but if something doesn’t work, I’d like some kind of indication why and what I as a user or someone of advanced competence can do about it. (See Linux vs. Windows for example)
The issue you are facing about lagging and not responding tech is threefold:
Microprocessors can do so much more than electromechanical parts of old, for much cheaper and take up far less space. The downsides are that they are embedded on a board and can’t be replaced without specialized tools, and second is that some companies (looking at you, Apple) bar the chip manufacturers from making replacement parts or put onerous software blocks so that independent technical experts cannot repair it themselves even with the skills and know-how.
Personal appliance device makers, to save money, use the cheapest processors they can get away with, which are slow compared to the software they are expected to run. So they lag, and they need multiple taps to respond.
Software makers tend to have high end hardware for developing and testing, though some product makers will have test devkits to emulate hardware. Like the makers of an app for Google TV don’t have every specific model of TV. When they update they have to make assumptions about hardware performance, or they just don’t care and ship something unoptimized.
