I dropped my Nexus 5 because it was so large, it was perilous to handle with one hand (whenever a notification comes, swiping from the top is a pain).
I am looking for a phone with these strong requirements:
- Shorter than 13 cm in length, the smaller the better
- Hardware is usable with alternative Android distributions (this excludes makers that DRM the camera and make it work only with maker-provided apps, for instance)
- Able to run the latest Android version
- LTE or better
- At least 16 GB of storage
Bonus for a good rear-facing camera. Bonus for open spirit (à la Fairphone, Nexus)
Plastic is OK. If not commercially available, second-hand is OK.
