My phone just got updated to Android 2.3.3 (Gingerbread) and I noticed an issue with my apps. It serves me right for not testing under the 2.3 emulator. Anyhow, what I noticed is that control values (e.g. EditView text) are cleared when the phone is tilted and the orientation changes. I knew that some things were lost in this (for example, the item in a list which is selected), but in my testing and on my phone, simple controls like EditView kept their state.
No more. Also, I have to say that the emulator does not work so well under 2.3. Yuch.
