[Sony Xperia 1 V] mufunyo:
Having recently returned my Xperia 1 IV because of the green screen issue, and having received a refund instead of a replaced screen, I took the opportunity to pre-order the 1 V. In the month or two of having to wait for the pre order my poor old XZ3 got worse and worse, to the point where the radio would fail and either wifi or cellular connectivity would die, or both, requiring several reboots to fix. It's had a good 5 year run, and amazingly no sign at all of OLED burn in. The screen is basically pristine as the day I bought it, bar a few tiny surface level scratches that you can only see if you look at it with the screen off, from the side, catching the light. Anyway, enough about my old backup phone.

Coming from the 1 IV, the 1 V is a pretty big improvement. The thermal issues are completely gone and you can stay in 120hz mode all day. The green tint issue from the 1 IV has been addressed, but not eliminated completely. Below 30% brightness or so, dark tones gradually become more green tinted, but it's very mild and there is no "bump" above black like the 1 IV had. Between 50 and 80% brightness gamma and white balance are mostly okay, but you definitely need to find a sort of middle ground in the white balance sliders where white doesn't become too pink, and darker tones stay neutral and don't become too green. At 80%, there is a sudden change in the screen, just like the 1 IV had, where all of the green tinting disappears, but darker tones get crushed to black and with night light, everything just becomes brown. I would say only use such a high brightness when you're outdoors and you need it to read text in sunlight, because it's not very colour accurate. I might make a separate thread about the screen, if I feel like documenting this more. In any case, there is a very new XPosed module (two weeks old) which can solve the green tint even further and make it an almost non-issue: Pseudo DC Dimming. I use it with the minimum HAL brightness set to 20% which is a good compromise between colour banding and getting rid of the gradual green tint when the screen brightness goes close to 0%. No solution is perfect here but I'm happy with the phone and I don't feel the need to return it or anything like that.

The rooting and customisation process was even more painless than with the 1 IV. There is one slight catch in that you have to patch init_boot.img with Magisk instead of boot.img, and you need to boot into fastbootD instead of fastboot to flash it. To do so, boot into fastboot, then use adb reboot fastboot to go into fastbootD, which shows a kind of recovery-like menu when booted. From there you can flash init_boot. FNG still works, and since last year, XPosed Edge Pro now gained the ability to hide not just the status bar, but also the navigation bar! This means no need to mess with Magisk Hide Props Conf unless you want to enable in-band BT ringing, which I haven't done yet.

The main thing that doesn't work, as reported by others, is PIN locking. You cannot set a PIN lock, it will crash the setup until you stop trying. I didn't feel like taking the risk of flashing the Chinese firmware which already contains the bug fix to that, so I'll just live without screen lock for a few weeks until the European version of 67.0.F.1.135 drops.

As before, there is no loss of functionality from unlocking the boot loader that I can see, other than the annoying warning when booting.
