Hello, I understand your anger, we are seeing new flaws in each version of BB, and with each version is a Russian roulette. I am sure that they carry out tests with the new versions, but there are many possible combinations that they can not test, it is a pity that there are always serious failures in the new versions. However, the Beta versions are for testing the Software, but I believe that users should not find such obvious flaws in these versions. The Administrators always indicate to make backups before using the new versions of BB, but many times we only see the failures when we have finished our project in the new version of BB, and we find all those failures that make us unable to finish our game. I have not currently exported to Android with BB 2.3.1, but if you want, I can help you through Teamviewer (PM).
