I have a 2nd generation SE iPhone and it’s locked through Straight Talk. Every so often it will randomly make a ‘pop’ sound which seems to be coming from the speaker of the device. I’ve noticed it happens when I’m browsing different apps and it happens sometimes while connected to a wall charger.
Hi shantelle23,
Let's see if we can help out with your iPhone. Hearing a popping noise isn't common.
Try cleaning your iPhone, especially around the speaker. See Cleaning your iPhone for cleaning instructions.
If you still hear this noise, we recommend contacting Apple Support by going to Get Support.
Let us know anytime you have questions.
Take care!
