I think its possibly more prevalent on lower end devices for whatever reason(remember probably a majority of android devices can be categorized as low-end).
Edit: I've just installed it on my phone(HTC One XL), it occasionally shows my normal desktop first then the it opens. For the most part though it seems to be working.
Some criticism(Not trying to be rude):
- Text is hard to read
- Background is plain ugly
- Seems to fail when no data connection is available.
