2. Use the web cam to display the text on the phone screen on your PC
3. Use an analog or digital magnifier glass
4. Use the built-in magnifier of your phone

Hi Herbert,
Thanks for your purposefully helpful kind advice, which I appreciate.
You've helped me a lot over the years, where one of your most famous contributions was the "certutil -f -decode %~f0 showwin.exe>nul" trick.
Little did I know at the time, as I used that script for years, is that at
some point the Genymotion scrcpy folks wrote a vbs script to do the same.
As for the local zoom in an activity, the problem, for me, is Samsung. Apparently, Samsung won't let me do the simplest of zooms I want to do.
Even so, I finally figured the whole damn thing out, and it just sucks.

The more I deal with my Samsung, the more I realize there are 2 Androids
1. Pixel Android (clean, consistent, predictable, open, configurable)
2. Samsung Android (not the above)
In terms of zooming, Pixel Android uses the accessibility framework.
a. On Pixels, triple-tap magnification works everywhere
b. Hence, scrcpy gestures behave predictably
c. System gestures don't conflict with accessibility
Yet, in terms zooming, Samsung rewrites Accessibility
a. Samsung removes triple-tap magnification on my models
b. Hides magnification options depending on other settings
c. Blocks gesture-based accessibility during screen mirroring
d. Replaces Google's gesture recognizers with Samsung's own
Worse, Samsung uses the same words (shortcut, triple-tap) as Google, in
terms of accessibility, but they mean completely different things.
On a Pixel, a shortcut is an icon I tap to start something, while a
triple-tap anywhere on the screen is one way to do a zoom.
On Samsung, a magnification shortcut is simply a way to activate the
magnifier, like a switch, where one way is via a triple tap trigger.
Samsung lets us choose how to activate the magnifier.
They do not allow us to zoom the screen by themselves.
They only turn on the magnifier.
Samsung:Android13
Settings > Accessibility > Visibility enhancements > Magnification
Magnification shortcut = on
Longpress on that last setting to open another activity to set
(_)Tap Accessibility button
(x)Press nd hold Volume up and down keys for 3 seconds
(_)Press Side and Volume up keys
(x)Triple-tap scren
Then I go to the Developer options > Wireless debugging activity.
The first time I use two hands to press & hold volume up & volume down,
after I inevitably end up changing the actual media volume controls,
I get the warning:
"Use Volume keys for Accessibility?
Press and hold both Volume keys for three seconds to use Magnification.
You can select a different function in Settings > Accessibility >
Advanced settings." [Don't use] [Use]
And then, the second time I use both hands to activate it, I get a blue
border around the entire screen, where I can pinch to zoom at a location.
It's clumsy, but I can tap on a teeeny-tiny port and that zooms to it, but
then I have to move the screen around because the zoom is imperfect.
The clumsiness persists in that when you want to zoom into the second port,
I can't just move the screen. I have to first tap and then move it.
Exiting takes two hands again, as you exit the blue box how you got in it. Since two hands on a phone is clumsy, I set the triple-tap next.
Now, when I triple tap, I get a blue box with the suggestion:
"Drag the handle to move the window.
Tap the handle to adjust the magnification"
Again, exiting is a clumsy repeat of the say convoluted entrance method.
Apparently Samsung removed the elegant Pixel-style "triple-tap to zoom" and replaced it with a magnification mode that behaves like a clumsy separate
tool we must enter and exit, not a gesture we can freely use.
Anyway, I got it working (for some forms of the definition of working).
It just sucks.
I'm hoping there is a special magnifier tool app that actually works.
