F-Droid is a nice app store that provides free and lean software. The idea of using old phones with modern software from F-Droid is quite obvious. There are several problems with e.g. F-Droid and Android 4.x but there are also several hints in this forum. Please help to collect them. This is a wiki thread, that means, most users can edit this post.
Helpful android apps
- F-Droid Classic version 1.2 (2021-06-01) supports Android versions >= 4.4 (will be the last version to support Android 4.4)
- Mounts2SD is a script for devices with low storage capabilities, but It can be used for a lot of things and is useful on almost any device, even those without external sdcard. It needs root and can configure swap, zram, mount optimzations and other things.

The certificates (and ssl versions) can be too old
- Conscrypt Provider | F-Droid - Free and Open Source Android App Repository provides TLS 1.3 to apps supporting older Android devices. App Developers will need to add code to their apps to make use of this provider.
- Lack of TLS 1.2 breaking apps in older Androids, more details about conscrypt and the background

- Gpg signature - No more SHA1 please!
Repositories
- The F-Droid archive repository is included, but not activated, in F-Droid and F-Droid classic. (it crashes my Galaxy J1, maybe because of low ram (512MB). If your phone has no problems, you may get the old apk versions which can be used by old Android versions)

Preparing an old phone with less bloatware
Getting rid of old software may improve the responsiveness of your phone.
- do a factory reset to your phone
- When starting first, don’t add your wifi to prevent google and other software to update
- Deny everything to google and other software, e.g. Samsung App Store.
- remove or deactivate every preinstalled software you don’t need (maybe keep the browser to install F-Droid)
- activate your wifi
- install F-Droid classic or something similar, either from SD-card or using the preinstalled browser
