Android 8.0 Oreo has been running into a lot of troubles lately. The latest issue to pop up on the version is the crash of settings app whenever users try to check mobile data or WiFi usage. The issue has already started annoying users who keep a tab on their data usage. Apparently, settings app gives up as soon as data usage option is tapped.

A user named Artem took to Twitter to share the issue he has been experiencing on his Pixel XL phone. Several other users also replied to his tweet claiming that they are experiencing the same problem, too. Another tweet by Eddie Ringle states that the fix for this issue was submitted to the main branch of AOSP, but it didn’t get included in the Pixel XL’s Oreo release branch.
