Hey there, jayzawu! Have you enabled and disabled it again? You can also try and wipe your cache partition. Doing so clears out temporary files from your phone's operating system. It also cleans up any extra files from apps you have already uninstalled. This can help resolve some issues as it clears out potential bugs. It's completely safe, and here's how you can do it:
Turn off device
Connect your device to a computer
Press and hold the Volume Up and Power buttons
Once the Android recovery screen shows up, release all buttons
Use the Volume Down button to hover over "Wipe cache partition"
Press the Power button to select "Wipe cache partition"
Use the Volume Down button to hover over "Yes"
Again, use the Power button to select and confirm your choice
