Don't Install iPadOS 13.5.1 If You're Nervous About Bugs
If you're having an excellent experience on iPadOS 13.5, iPadOS 13.4.1, iPadOS 13.4, iPadOS 13.3.1, iPadOS 13.3, iPadOS 13.2.3, iPadOS 13.2.2, iPadOS 13.2, iPadOS 13.1.3, iPadOS 13.1.2, iPadOS 13.1.1, iPadOS 13.1, or iOS 12, and you're nervous about iPadOS 13.5.1 potentially hurting your iPad's performance, you might want to hold off on an upgrade.
The iPadOS 13.5.1 update is an important update, but the update's brought problems to some iPad users.
The current list of iPadOS 13 problems includes issues with first and third-party applications, Bluetooth problems, weird battery drain, problems with Wi-Fi, issues with cellular data, UI lag, random reboots, issues with Face ID, problems with Exchange, and more.
If these issues concern you, you might want to hang back and wait for more feedback about iPadOS 13.5.1's performance or, in some cases, for the next version of iPadOS 13.
