If that's a real need you have maybe it's better served by a dedicated device. There are plenty of wearable panic buttons on the market.
For smartphone typing, The last couple of Android versions have traceable keyboard as standard iirc. Way easier than hitting the tiny letters once you adjust. Just get a big enough screen.
But Voice recognition is good enough to be useable now, with a modern android phone you don't even really need to type almost ever if you're willing to adjust your workflow a bit. This is the direction these devices are heading, not back to pressing individual buttons like its the 19th century. Have a look at one of the new Motorolas imo, well built for the money and minimal bloatware.
Roughly two human generations of y'all now have missed the entire point.
We are not luddites. Some among us beta and alpha tested the very technology you are NOW trying to "sell"
back to its own pioneers!
Many of us are "computered up" to
very high levels of AVAILABLE technology.
We are simply more selective as to when and how we use it. How many minutes or hours of a given day we permit it as reasonable rations for value returned.
The difference, y'see, is that we are not "reactive" to those market forces and fads.
We still wish to
pick and choose just which type of "service" or portions of them, how much and how deeply we will ALLOW intrusion, distraction, interruption or annoyance to balance against any genuine gain for
our convenience.
For a great many of those 'featured services", we do NOT see a genuine advantage to the way we wish to live our lives. They are not the same choices, one to another, either.
Ex: I dont have voicemail, no longer wear a pager, and won't ordinarily even read text messages. One arrives that is of interest? I hit a button and call back, live voice, right now.
ELSE delete.
No apologies.
After more than FIFTY YEARS of it in one form or several, Military and Civilian, I am NO LONGER on 24 X 7 X 300-plus "emergency callout".
If it matters, to YOU? Try calling me at another time of day. Or another day. Or next month. Or never.
I've got a life of my own, regardless. Gadgetry is meant to serve MY needs, in MY choice of shape, form, and function. Not the other way 'round.
Annnnnd.. sole and only Wife the sole and only exception, the entity at the OTHER END of that bandwidth? Does NOT have a blank check, issued in advance on any part of my life just because THEY have adopted a slice of technology as suits THEIR instant-gratification existence.
The "existence" of a raft of gadgetry does not compel adoption.
It only interests me for what I actually find useful. Or NOT. To ME!
The rest of the eye-candy and earbud
distraction can go pound doped Silicon up its multi-core variable clock-speed virtualized arse.
Believe it or, not there are still people on the planet - even young ones - wise enough as to life's genuine priorities that they will NOT take an incoming call while enjoying good sex....or taking a dump. Or enjoying a cup of tea.
Really. Vanishing breed, it seems. But there are still the odd few holdouts..
(NB: How TF would you virtualize Astroglide, orgasms, or ignorant toilet paper anyway?
Nah. I don't think I really want to know. Some of you lot will have more than one answer, and those damned no-key finger-swipe "handhelds" are like to be involved..)
