IPhone X stopped working underwater
Yesterday for the first time I put my iPhone X underwater at a depth of less than 50 cm and less than 7 min. iPhone stopped working. Right now touch-screen doesn't react to any tap but the screen still working and shows time and "Swipe up to unlock".
Does it mean that iPhone X hasn't any waterproof?
Can smb advise on what I can do to make touch-screen works again?
Thank you!
iPhone X, iOS 13
