Last weekend my Nexus 5X did the Boot Loop Thing (Article in German, refund only for US customers).
So I needed a new device, quickly. I am certainly not spending 1K Euro on hardware, so I was looking for a Nexus 5X priced device that does not suck.
Harald recommended I am looking at bq.com, a spanish company that makes 3D printers, and smartphones, and indeed the X pro delivers. 5X sized, the device can do dual-SIM or SIM+SD, has up to 128 GB memory (I got the 64 GB model), a decent camera and a close to stock Android with a bi-monthly update cycle. Android 7.1.1 with a late 2017 patchlevel in my code. Less than 300 EUR, performs as advertised.
Oh, and the selfie frontside flash is Men-in-Black level weird.
