That’s a new feature for larger screens in the latest release. Right now, there’s no way to disable it – but the developers are keeping an eye on the response.
I reported the same issue on Discord, copy/pasting here -
**Remove AnkiDroid split deck picker screen on 2.24
**
What it says on the tin really. Ankidroid updated overnight on my Samsung tablet to 2.24, and now the main screen (deck picker?) is split in 2, and it’s increased friction: I used to just have to tap the name of the deck to study it, now I need to tap it, then move down and to the side to click on study. I looked through the config options, but couldn’t find a way to remove this terrible split screen, please someone tell me there’s a way…
I’m not a tablet user, but I agree with this being annoying. I even mentioned it on Reddit a while ago (the split screen existed since a long time, but it seems that the tablet “threshold” has been reduced in 2.24 so that more devices are considered tablets now).
