Recently i saw an article about a German Startup creating a privacy focused Phone:

I do like that they promote Ubuntu Touch and i do like that they created a Google Free Custom Rom.
But when it comes to my experience with Android, i do have critics on almost every Phone Manufacturer.
For a few years, phones have been sold again and again with the principle that they use AOSP and do not change much and have a long support.
While the manufacturers keep their promise, most manufacturers are lagging behind with updates and this is a big issue when it comes to security.
