I used to use the volume key accessibility shortcut to turn on the Torchie app whilst the lock screen was on. I would hold both volume buttons and the LED flash would come on to use as a torch. However, it doesn't work anymore, I think since the system update in June. The app can still use the LED as a torch, but the accessibility shortcut doesn't work anymore.
Any ideas how to get it working? Or is this a "feature" (bug) of the new system update?
