I gotta need to say something without trying trashing the vivo. Just my clear opinion.
I had the vivo x90 pro plus for like 5 days and already returned it. Don't get me wrong, it's a solid phone, I had the X60 Pro+, the X70 Pro+ and the X80 Pro so I knew what was coming at me regarding Origin OS.
But for almost 1050€, the speakers were quite disappointing, the haptic motor was trash. If you used an iPhone before, you maybe know what I mean.
Battery was okay. Scrolling through YouTube (Shorts) was a nightmare. All videos had like 360p quality, but restored to HD little later. Kind of annoying.
If you set the Screen refresh rate to adaptive, I haven't had any clue why almost every other app downloaded from the play store had 60Hz. Changing the refresh rate to continuous 120Hz solved the problem. Why is there even LTPO-Tech inside?
Leaving bluetooth turned on - setting Spotify to my standard music app in the settings - and hopped into my car, the phone was not able to play music automatically. I would be forced to grab my phone out of my pocket, open Spotify and press play. First world problems - I know. But not for me.
Downloading a workaround-app from the play store solved this problem - but why?
The camera was great, but I compared it to my iPhone 13 Pro max. The vivo was better of course - but I have to say, it didn't blew me away. The X60 Pro Plus back then was really mind blowing - but I guess years have gone by with camera tech.
Conclusion (for me): It's too expensive for what it is - I'd pay 800€ for it. But I guess thats not fair to say for a china-only phone. But maybe you know what I mean.
I bought the S23 Ultra a few days ago, and I gotta say, the X90 Pro plus doesn't even come close. Camera is not everyhting I guess.
TO ALL : If you love your X90 Pro Plus - I'm happy for you! I know my problems don't apply to everyone. I just want to share my (subjective) opinion on the X90 Pro plus (vs S23 Ultra).
