Very well written 👏 thank you for such a well written instruction sheet!! 🙏
Awesome, thank you Sir.
I've read and watched a couple other guides; when replacing the back cover they mention that even replacing the back cover with the adhesive it comes with; the phone will not retain its IP68 rating and requires a rework with both back cover adhesive and screws to retain its water protection.
If I follow this guide exactly, will my S20 Ultra lose its IP68 rating?
A+ Thank you for a great tutorial! Well written and easy to follow. Thank You!
