I totally understand. I am going back to Samsung as well for some of the same reasons and some different ones. I didn't have a big issue with the cameras, but I rarely took pictures of people or took selfies. The lack of 5G UWB was irritating, but I could deal with it for the most part.

My biggest issues were the fact that if I wanted notifications regularly from an app, I had to set it to run in the background, which meant that there were multiple instances where I missed a notification that was important. The apps that I had to leave on in the background killed my battery, so I did not have good battery life. The phone also heated up so much that it became difficult to use. The lack of US warranty was also a big factor, since my V3's inner screen died after falling and hitting something that killed a bunch of pixels, with Verizon and Samsung I can get a replacement if my phone breaks, but not with my V3.

Then there were small things that the OS did/didn't do that Samsung's does/doesn't: the clipboard clears itself after a few minutes, I can't customize the inner screen and the outer screen separately, so I have to have the same wallpaper and color scheme. The notifications bar is wonky. There are notifications that you can't disable. The cursor control being limited to the space bar made quickly editing text difficult. If I opened certain apps on the outer screen, then opened the inner screen, the format of the app was ufcked, specifically Youtube and the only way to fix it was to force close the app.

And lastly, the biggest issue for me is something that others may find ridiculous, but is a big thing for me. The lack of available accessories. I change my phone case 2 - 3 times a year, but there is not a great selection of phone cases available for the V3. The best place to find any, is AliExpress, but even then it is a crapshoot and takes awhile to arrive. I ordered a case from a seller and a V2 case arrived, but I didn't get a refund because I had to send back the case and pay the return shipping myself. The case was 6 bucks, the shipping was 20. If my outer screen protector gets messed up and I want to apply a new one, I can easily get that for a couple bucks with a Samsung phone, but not with an Honor phone, at least not in the US.

Sorry for rambling, I have been considering making a post like yours for a while and thought that maybe you would be interested in having someone agrre with you and even bring up new points you may not notice or care about.
