However, thankfully Apple does seem to be at the very least on top of the issues at the very least and have been steadily releasing fixes for it. The latest release comes in the form of iOS 13.1.3 in which it follows the iOS 13.1.2 update that was released two weeks ago. Based on the version number, this is not a major update and will be mostly focused on bug fixes and what not.
There are numerous fixes in this update, one of which will address issues where some devices might not ring or vibrate when receiving an incoming call. Another issue that is fixed comes in the form of a Mail bug that might prevent a meeting invite from being opened. These fixes don’t just cover the iPhone but it also includes the iPad.
If you have yet to update your iPhone or iPad, then you might want to do it ASAP as the update could potentially fix some of the problems you might be experiencing on your device.
