I got a Honeycomb tablet a couple of days ago, a Samsung Galaxy Tab 10.1 3G to be exact, and as soon as I logged in usgin my Google account, the device recovered all the apps that I had installed on my Galaxy S. Keep in mind that the Galaxy S runs on Gingerbread 2.3.4 with a lower resolution, so I thought there could be some differences. Surprisingly, the apps mostly worked just as they should, but there were a few exceptions that i’d like to point out.
The Good: IMDB
IMDB Main screen
IMDB Series view
I’ve been completely satisfied with the normal mobile app from IMDB, but when I first opened the tablet version I was amazed. It’s well designed, graphically impessive and fast. Also, it works both in landscape and portrait orientation just like it should. The search prediction is fast and shows information properly and the subpages work well. The only minor flaw is that the windows of the detail pages are a bit too small and require scrolling.
The Bad: Facebook
Facebook "app"
See, no Facebook for Android!
Well, to every tablet owning Facebook user the reasons behind this are pretty obvious. The problem with the app is: there is no app. All facebook has to offer for the tab is the new messenger app. The surprising thing is that even the phone version of the app can’t be downloaded and scaled. So until Facebook releases the next update, better get used to the browser interface.
The Ugly: Speedtest
Not really optimized for tablets.
At least it works
I’m sad to say that this is not the only example of an ugly app for a tablet. Sure, on the phone it looks great, but when I opened it on the tab it looked like an early 2000′s Flash app. You remember those, right? The small screen size guarantees usability problems and it just looks so stupid sitting there in the middle of the screen.
This isn’t the app’s problem per se, but Honeycomb’s scaling functions are not used for some reason. As far as the scaled apps go, most of them are used in fullscreen mode, which leaves the bottom of the app behind the status bar (e.g. Spotify). Oh yeah, and speaking of Spotify, it only works in landscape mode. And on older tablets (Samsung Galaxy Tab) it only works in portrait mode. Why? Beats me.
Stuck in landscape, notice the song position?
Since the Honeycomb platform is relatively new, there are still a lot of apps that could use a facelift for the new resolutions and interface elements of the tablet-optimized OS. Until then, be prepared for some funky-looking legacy apps
