My new iPhone 7 Plus 128GB matte black has a screen vibration issue when I'm playing audio. When I am listening to a podcast, or playing a song, there seems to be excessive screen vibrations when I place my finger on the screen. It's like the audio vibrates the entire screen. I often like to put my phone in my front shirt pocket and play music / podcasts when I'm walking. Now it feels like i'm receiving vibrating text messages the whole time. I don't have this issue with my 6 Plus and 6s Plus screens. Those screens are solid. I'm not sure if this is due to the new stereo speakers being much louder on the phone. Or maybe the screen is not glued on tight enough? Anyone else notice this issue? Play some music or a podcast on your phone. Place finger on the screen. Does it vibrate excessively?
