Issues with iPhone 16 Pro Max – Speaker and Screen

Since I bought my iPhone 16 Pro Max, I’ve been experiencing two issues. The first one is with the top speaker – when I increase the volume past halfway, the microphone starts to crackle. This is especially noticeable during phone calls, and the sound quality becomes very bad. The second issue is that sometimes, out of nowhere, the screen stretches for a split second, and I see green, black, or other colored lines. These lines appear in different parts of the screen, especially when I turn it on or in certain apps. Even the Always-On Display sometimes glitches. I’m starting to wonder if the phone is defective or if it’s a software issue, as updating to iOS 18.0.1 hasn’t fixed it. Does anyone else have this problem with the new iPhone?

Yea same issue here, when the volume is higher the top speaker makes crackling sounds and sometimes when watching normal videos the audio shifts between left and right. The speakers also lower the volume at points and raise them back again(even when the volume is turned up completely) on music and videos. Hopefully Apple can fix this. There is no way they don’t know this is happening.

If my volume is up more than halfway on my new iPhone 16 Pro Max, anything other than a voice coming across the line sounds horrendous. For instance, if someone typing as they’re talking to me or looking for something and rummaging around, the sound of it has a piercing high end that gives me an absolute headache. It pokes through so loud that I have to keep turning it down. And then I can’t hear their voice basically. I literally need to get a different phone because I just don’t think I can do it unless they fix it. I get migraines.

I usually use the “Apple Support App” to investigate any issues and refer to articles relevant, which the app automatically populates from a lille description of the problem. It can also use the Serial Number to check warranty (limited 1 year) or AppleCare (if applicable) and tells the eligibility for paid/unpaid service options available best for you.


From there you can choose the option suits you like scheduling reservations to nearest store or send-in etc. Scheduling can be done for a week ahead max.


Here, is an article I found when searched speaker/loudspeaker. Sometimes a quick look can be very rewarding and save you efforts as last I remember I had to backup the phone, erase the device after I sign out and oops, I will regret this a few days later as I never updated my phone number linked to the AppleID.


If you can’t hear any sound or hear distorted sound from your iPhone, iPad or iPod touch speaker – Apple Support (UK)


Another reason for replying on this post is to share that some phone models may get replaced/repaired under replacement programs for similar issues reported and do check it out.
