Unfortunately the phone parts cost about the same price of a used phone. I have a Samsung Galaxy s10 plus that I bought off of someone who needed money and got a great deal. I only paid 300 dollars and it was in perfect condition. The fact that if I damage the screen it will almost cost as much to fix it than what I paid for it. And I am talking about the cost of parts. I can repair it myself. I would recommend getting an iPhone. They are quite a lot cheaper to repair. Even if you get the new iPhone se 2020 a new screen only costs about 25 dollars, you can use the screen from a iPhone 8. I hope you find a new phone.
