On some screens it seems to be that the beta is "out of focus". The reason for this is because we are not yet ready with optimizing the beta for all screen sizes. This is a very long process and we will have to literally build in hundreds of different phones and sizes. Although it should already work on most, in some occasions it will look a bit weird. A little like this:
For most phones, this would be a font setting though. The beta currently only works (for all phones and sizes) with the native (normal) setting of the font size. We will be looking into expanding our app to automatically adjust to those settings as well, but for now it will show very distorted on anything but the native phone's setting.
