The specs overview, from the iFixIt teardown:
- 5.65" IPS display with 1080 × 2160 resolution
- Qualcomm Snapdragon 632 SoC
- 4 GB of RAM and 64 GB of storage
- 12 MP rear camera with ƒ/1.8 and a front-facing camera with 8 MP ƒ/2.0
- 3,060 mAh battery
- Fingerprint sensor, headphone jack, and IP54 rating
So nothing startling. Except that you can get into the phone with just a fingernail:
A standard cross-head screwdrivers then gets you into every other major component or module.
The main objection to such an 'antiquated' way of building phones is that there's no waterproofing, but the fact that you can strip it all apart and dry everything out in (e.g.) an airing cupboard does go a long way to mitigating this, i.e. I've had family dunk phones a dozen times in the last 15 years and I've never lost one yet - they've all come back to life after suitable drying!
Do see the full iFixIt teardown for more photos and comments, there's an awful lot in common with the classic 'Lumia 950' hardware design - it even has a 3.5mm audio jack!
If you're wondering, this is 450 Euros from the Fairphone site.
