Samsung Galaxy S20 Plus mobile phone

Samsung 20 Plus Note:- There are two issues: First: The battery is weak, but the charging duration is normal 🔋. Second: There is a green line that suddenly appeared on the screen, I didn't drop it or hit it. (I have never dropped it or opened it. Between me and you, I didn't take it to Samsung service or any repair shop. The device is extremely clean, always sealed, and has a screen protector.) This is a device running on Sumsung OS, God bless us and you with goodness. Thank you
