Unihertz Jelly pro as a bike computer

Looking for a new bike computer as the Sony Ericsson Xperia active phones are failing and don't have enough memory, are slow, etc.

Found the Unihertz Jelly pro on Amazon. It has a tiny 240 x 432 pixel screen, a 1.1 GHz quad-core processor, 2G ROM / 16G RAM running Android 7.0. I put a 32 G SD card in. More specs here. I used the Jelly pro on a 3 hour ride (with screen brightness at minimum) and the battery still had 50% charge left. This is comparable to other Android phones I've used for CycleBike Smart. The GPS only uses Navstar satellites, not GLONASS, but it has A-GPS that uses cell or WiFi to update the almanac and ephemeris of the satellites to get a location quickly.

The Jelly Pro has a plastic case and doesn't look like it would stand up to bad weather. I put it in a silicone case before attaching the Polar quarter-turn mount


Here's the Jelly pro mounted on the bike with a Polar quarter-turn mount. Notice also the Anker external battery mounted under the top tube with velcro.
