I’m running 14 on it currently

I’m satisfied with my https://moondroplab.com/en/products/miad01

It’s got two jacks!

Battery is good for me. Lasts about a day and a half, almost two days through my standard use. Hasn’t dipped from that at all in the months I’ve had the phone. Super quick charge.

Battery is replaceable as well. Haven’t done it myself but it’s looks very simple.

Stock android. There was an initial issue I had with the physical keyboard mis-matching keys (I’d press one character, it’d type another) but there was a fix I found from the fxtec forum by disabling “Accessibility” permissions from “Android Assistant”.

I am currently typing from the Fxtec Pro1 X, using Android.

It’s great for me with the stark exception that it has recurring issues with dropping signals, be it mobile 4G, Bluetooth, or WiFi. I would not say that it makes things unusable at all… just occasionally annoying. It’s usually fixed quickly by switching to airplane mode and back.

The most annoying part is that I can very rarely use it as a telephone unless I’m on WiFi. People report they can’t hear me at all only very broken and garbled when I’m on mobile signal (T-Mobile carrier). This seemed to have been resolved by my using my smart watch to make calls which appear to go through without issue.

Freaking love the keyboard on this thing though, so it’s worth it for me.
