Spinning wheel appears suddenly and disappeared

Hello Omarksm! Thank you for participating in the Apple Support Communities.

We understand that your iPhone is unexpectedly displaying a spinning gear. We'd like to look into this with you to see how we can help.

First, let's make sure your software is up-to-date, after creating a backup for your iPhone: Update your iPhone, iPad, or iPod touch

Next, let's check Settings > Battery > Battery Health. Does your battery report that it needs to be serviced?

Make it a great day!
