I just purchased an IPhone 12 Pro Max 256 GB. I often listen music on my iPhone. The problem is:
Recently, my ear very often got hurt due to music volume suddenly increased to maximum at very low volume. This happens frequently.
After repeatedly testing my iPhone, the problem can be reproduced by:
1. Open the music app and play the music at low volume (either with phone speaker or earphone)
2. Press the sleep/wake button and immediately double click the volume-up button upon turning of the screen.
3. The volume will suddenly increase to maximum to explode your ears.
If it fails, try it for a few more times to reproduce the problem to see if your iPhone is normal.
So far, I can only reproduce this problem on my iPhone 12 PM, but not my iPhone XS and iPhone X.
A fresh install of iOS 14 cannot solve the problem.
