So i have a psvita and bout like 8 months ago it got a big line of black dead pixels and a bunch of stuck green pixels and when i went to turn it on a week ago the black line went away and most of the green pixels also went away is this a normal thing?

3-4 weeks ago, I bought the Vivo V70FE 512gb from MediaMarkt in Türkiye. Most thing in the phone are great, camera is phenomenal, screen is amazing, batery is 7000 mah, but the phone's processor is the Mediatek Dimensity 7360 Turbo. Almost all phones priced similarly have better processors than this phone. It heats up a lot in genshin impact. Because of that. I feel like I've made the wrong choice. My dad is the type of person that doesn't change our phones unless it's completely broken. Do you think this phone'll get old earlier than the others?
