I bought a unihertz Titan to replace my BlackBerry Passport. Nagging complaints about the Passport included: short battery life, flaky Qi charging, terrible cameras. Complaints about the Titan include: Android, the unit itself is heavy (with sharp edges around the case), and also, Android. I’m not sure yet which is worse. The Titan does offer some pleasing upgrades: IP67 dust/water resistant, good battery life, Qi charging works well, wider range of working/performant Andoid apps. But it’s still Android.
I’m documenting my experience. I’ve posted some tips on the device’s quirks and workarounds here.
