Pinephone Pro here, I wanted to use it as a home automation controller around the house, I think I bricked the keyboard case attachment by using the wrong charging port (why is that even a thing??) because it doesn't work, but to be fair, it never did work, and I've tried troubleshooting it for a few hours with no joy, so now I'm just kinda too frustrated with it to sink more time into it and it's sitting in a drawer.
I should probably try postmarketOS on it and use it as a burner travel phone.
You only mention installing, but did you have to configure tlp & irqbalance? Battery life is all that's keeping me from using my pro as a daily phone :)
1. Yes, has a dialpad. Works as you would expect
2, 3, 4. Yes, works well on my carrier
5. The antenna is along the side of the phone I believe and the reception seems good, I haven't had issues with this
6. I would say SMS only works about 95% percent of the time. The phone does randomly disconnect from the celluar network maybe once every day or two
7. Works well on my carrier, no issues here. I have a data plan and it works fine
8. It takes maybe a minute or two to boot, but to be fair my Samsung A52 Android takes longer to boot, maybe 2 minutes
9. Yes, there is a contact app, don't know about snake :)
Other:
10. The phone is slow, firefox works and all the websites I visit (including google maps, uber, etc.) render and work correctly, but slowly. I wouldn't say too slow to browse, but 100% it is slow
11. Be CAREFUL inserting the SIM card, it is extremely easy to break the SIM pins and brick the phone if the SIM card is not inserted correctly (I learnt this the hard way)
12. Surprisingly a large amount of apps available via flatpak/flathub, including both foss apps for things like email and 3rd party clients for things like spotify and whatsapp (text only, no video or audio calls). All the core linux stuff and lots of the foss apps via apk
13. However not all apps on flathub are compatible with the PinePhone since PinePhones uses aarch64 architecture, not x86_64
14. Very poor battery life out of the box, about 4 hours tops. However, after installing tlp and irqbalance (via apk) and setting auto-suspend to 1 minute, the battery life is about 8 to 12 hours of "normal" usage, so quite usuable
15. Camera is very basic
