Yeah, they pushed an update that made the device completely unusable. I'm not sure if that was related to the issue with the storage on it also degrading. I still have it and I managed to load a custom rom on it but it's still remarkably slow. It's too bad, too. The device itself was (and still is, IMO) something that I'd love a modern version of without all the issues. I also had a nexus 5 phone which was great (and aesthetically it's still my favorite phone ever)... until it got stuck in a bootloop 2 weeks after warranty... which they helped me out with and sent me another one out of warranty, but that replacement also almost immediately started bootlooping.

After that I just can't trust Google at all with hardware and since then my opinion of Google as a whole has largely soured. The Galaxy S6 I got to replace it worked quite well but after several years went back to the iPhone .
