Why does my iphone 4 zoom into the lock screen? Sometimes when i take my iPhone out of my pocket it is zoomed in to the lock screen and i have to restart my phone because it won't let me un zoom it. Why does this happen?
When I sing I sound good in my head but on recording it doesn't sound as good? I understand why this is but I want to know if it is because my iPhone recording quality isn't good. If not how do I actually listen to how others hear me sing.
Play music while recording yourself? I have an IPhone and I want to find an app that I can record videos on but play the music at the same time. I have jamcam but I have to hold the thing down in order to record. I don't want to have to hold anything. What if I wanted to record myself dancing? Also I don't have like any iTunes music so I don't have anything to import. So I need: An app that already has music I can import. Like Jamcam but no limit on how long the video are or music
Is there a way to listen to music while recording on an iPhone XR? I use my iPhone XR to record drawing time lapses. I like to listen to music while I'm drawing, but my phone pauses the music when I start recording, even when I have headphones connected. Is the a way to keep playing the music through my Bluetooth headphones while I record?
