Red stuck pixels on iPhone X screen won't go away?

I just got my iPhone X replaced for the third time and it's a brand new phone. As soon as I took it out of the box and turned it on I saw 2 red dots on the screen that wouldn't go away or move no matter what. So I tried all the things I saw online about how to get rid of stuck pixels, like "massaging" the pixel to get it unstuck, tapping the pixel with a pencil eraser, applying pressure to the pixel, using a hot wet cloth in a zip lock bag and holding that over the area the stuck pixels are in, and I've tried the J screen fix pixel repair which did absolutely nothing, and I tried multiple rapid color changing videos on YouTube that are meant to fix stuck pixels and I've left the videos on and the J Screen pixel repair on overnight and NOTHING has worked. The pixels got smaller from massaging them, but they won't go away. There's two of them and they are only noticeable on a white or lighter colored background. They're super tiny and barely noticeable anymore but the reason I want to fix them is cuz it annoys me that a brand new phone was messed up before I even took it out of its box. I've had the phone for about 2-3 weeks and the pixels haven't fixed themselves and all the things I've tried hasn't worked. My Apple warranty is expired and I don't have apple care. So if there's any other ways to fix stuck pixels that I haven't tried already Please let me know. I can't take my phone to be fixed by Apple or any other repair place, so I need ways to fix it that I can do on my own

Should I buy an iphone 8, samsung galaxy s8 or something else?

I'm a 23 year old who enjoys using snapchat, facebook, instagram, twitter etc.

I also want a phone that has various features in it and a great picture and camera quality.

However I also want to buy something affordable. I'm honestly considering the iPhone 8 or Samsung galaxy s8. What do you think? Or is there something better?
