scrcpy VS apilevels

There's also https://github.com/Genymobile/scrcpy which works for any Android, not just Samsung

How did you manage that? I mean, what's the app name? Maybe srcpy can help you: https://github.com/Genymobile/scrcpy

GitHub - Genymobile/scrcpy: Display and control your Android device

Needs android 11 tho https://github.com/Genymobile/scrcpy/blob/master/doc/audio.md

View and control the watch from the PC with scrcpy (only Wear OS 3).

Corollary to your statement: of the very small (<1%) group of users running such ancient versions of Android, 100% read HN and will be responding to your comment. As if it invalidated the stats on actual usage: https://apilevels.com/

Some input as an Android dev: the API level stuff is not nearly as much as a problem as it was some years ago. Nowadays you can easily require 23 or 25 (see https://apilevels.com/) - since 23, there were definitely some changes, but not terribly big ones that are really painful.

I'm rather getting a headache with new form factors (window insets, foldables, tablets being revived).

Also: Usually all google libs are backwards compatible to 21. The new ui system (Compose) just gets shipped with the app itself, increasing download/installation size. Apple does not do this afaik, they require a recent minimum OS version for compose ui.

You're right it's actually 75.8 %

According to this page it's just above 20% https://apilevels.com/

Try to go as cheap as you can find while also having a recent (max 2 years old, 1 year is better) android OS version. Take a note of your minSDK version set in your app's build.gradle file. When you purchase a phone make sure it supports at least that version. To translate API levels to Android versions you can use this page.
