It's not the same company as day one... Now is owned by Oppo. So basically is a Oppo phone that is for sure. And if you are looking for those super open phones to unlock add customs roms... Look another way.

For other stuff... Idk I have one it works well for me and it was a much cheaper alternative to Samsung or iPhone and with latest Snapdragon and plenty of ram and good hardware. Cameras idk if others are better I barely take pictures and usually I don't care a lot for the quality.

And the Chinese fast charging thing they have is amazing. (Also supports USB c pd quick charging although much slower)

No, it's not.

All the reviews I've seen praise it. It may not be the One Plus of old but as far as phones go it's one of the better one's.

I had a 1 and 5, family members had a 5t and 6. Honestly they never impressed me after the 1.
