Symbian Another thing that is a bit annoying is that actions in launcher don't work. To test that, activate talkback, open the launcher, then swipe left to right or right to left through apps. There is a point where talkback speaks something like screen 2 of 2 or screen 1 of 2. There you can swipe up or down and Talkback will speak launcher actions. Double pressing (talkback gesture to activate something) will trigger a message telling action not supported, and this is happening with every action. I need to trigger the actions using other techniques to open these menus! Can you please fix that? On other AOSP bassed launchers like Lawnchair this never happened, and since I discovered GOS I want to avoid some third party apps whenever they have native Android/GOS equivalent!
I'm not 100% sure I understand what the correct behavior is, and the behavior you're observing, but it sounds as if it might be productive to file an issue on the GrapheneOS issue tracker. It would be best to provide a numbered list of the actions taken and the results observed, and then to point out which step(s) produce unwanted outcomes. It could also be useful to go through the same steps using the stock OS, or using a different launcher. Creating a secondary user profile, installing Lawnchair, doing the test, and then deleting the secondary profile probably would be pretty safe.
If you don't have and don't/can't have a GitHub profile, you can post material on the forum and I can file an issue. I recommend starting a new thread, with a topic like "TalkBack doesn't announce some launcher actions" (or something like that). I would suggest the "General" tag (and I would suggest against the "Development" tag).
