Since the review thread is locked, I would like to post my view here after three months of FP2 usage. First of all the issues:
The camera is good in daylight, but below what I hoped for in low light. But I don’t have a lot of experience with smartphone cams - it is just that people with (even older) iPhones make pictures that are so much better that I hoped for a bigger improvement with a new camera module at the price range of the FP2.
I am convinced that battery drains on new phones and the heat issue are connected. The FP2’s processor is know to be a bad design regarding energy consumption. Some weeks ago I read an article that the same processor cores are consuming less power in other processors - can’t find it now, sorry. So if the battery is just 2800 mAh while other phones have 10-15% more, and the CPU is less efficient, this will of course drain the battery quicker. When my phone was two weeks old, I charged it over night and had a longer Skype call directly after unplugging. To my suprise, the phone compained about being at 15% after a while. I plugged it in again and noticed it was quite hot. Still, it could not charge as quick as it consumed power, and after a total time of just 1:38 hours, it switched off This all was with no other apps running, and I have no software issued otherwise and not exceptional heat during usual browsing. It’s just that this is not a phone for video applications.
The white cover did not prove to be a good choice if you like to keep your phone in a mint state. More info here.
And I did and do still experience the screen flicker issue, but there is a temporary solution.
Now the good part: If you can live with a premium of 350 € on a phone that otherwise (= not fair/responsibly sourced) would cost 180 €, it is a great and unique product. No guarantee loss on rooting, better spare part availability at fair prices, a great community online and offline. Less useless pre-installed apps. And it is one of the products that attract people that want to get involved. Like the Raspberry Pie or an old VW Bus.
It is probably a phone for those people who can live with a mid-range phone with mediocre performance and who can stand that the phone takes more of their attention than they originally hoped for, because they value the idea and hope that it opens the market for really good sustainable / fair phones. It is (unfortunately) still the best that exists in this niche today I think, but it is probably not best for users with no technical background, because they would miss the technical parts that are part of the value that justifies the really high price.
Well, I hope this helps somebody to decide for the FP2 and know upfront what he/she decided for.
