Iphone random popping noise
My iphone is making a random pop noise but shows no notification. Like a single bubble popping. We have turned off sound notifications on all apps that have nonspecific sounds. Deleted apps that are not in use. Closed all tabs in browser and cleared history. And updated all apps and software. If the phone is silenced you do not hear the pop. I have a video with audio of the pop sound if theres a way to submit that. Please help. This is causing a drain on my battery.
iPhone 8, iOS 11
