Android phones

Here you can find not-so-hard-to-find secrets about my smartphones, running Android

• Sony Xperia Z5 Compact The first Google-OS equipped phone I owned (page will not be updated any more).
• Google Pixel 2XL and it's successor, also dead, because Google stopped supporting it (page will not be updated any more).
• Google Pixel 6a and the current one.

Useful apps

Beware, I support most of what Tristan Harris has to say about Smartphones -in short, I think most apps are shit and a means to occupy your attention. On top of that, Android (and iOS) are some sort of scam to make you give away your private data. Find the more elaborate and more differentiated arguments on Medium.com.

• First thing: Install some self hosted calendaring and cloud software (I use Zimbra, as I don't have much need for file storage). Otherwise ownCloud or Nextcloud may be your thing.
• Second: Encrypt your device and it's SD-Card
• Follow one of the various How Tos for securing your device and disabling/uninstalling unwanted apps.
• Pay for the non-advertisement version of the apps you like (none of them cost serious money). Also -or especially- the Open Source ones. Even if they are only donationware.
