I would like to show you how I built a smartphone from a Raspberry PI. The problems and difficulties I encountered and the solutions I found. The project is not yet finished, there are still a few small things missing. Nevertheless, I want to show you my smartphone in the practical sandwich box and tell you how it came about.

I had no idea that building a smartphone could be so complicated. Raspberry Pi + touch display is not all there is to think about in this project. At the moment, the smartphone project lives in a sandwich box and attracts attention on the subway. If the power bank can passthrough, that’s an advantage, I’ve found. Setting up the X and Y axes on the touch display so that you can also use the on-screen keyboard was not so easy. And I had to realize that Landscape is not the right size to work smoothly. Most Linux programs are not directly touch-compatible or require too much memory. Then there were also big challenges! Learning to solder was one of them. First learning how to solder, then learning how to desolder, and then daring to use the PI. I would like to tell you these and other stories about building my smartphone.
