"The HUB isn't a "mess" in what normal Android users are used to. It is just a little buggy compared to the kind of integration that BB10 users are used to.

There are duplicate notifications if you say have gmail set up with sync and the HUB set up.. Yes.. But that's the same with **every single other** email client on Android. CloudMagic, Mailbox, Inbox, etc. You can just unsync your gmail client (requires a pull to refresh in the gmail client if you choose to ever use it moving forward) and it'll fix the duplicate notifications. You have to do the same if you're, again, using any other android email management client. This is no different.

Not having WhatsApp support is listed as another one of the factors that means the HUB is a mess? I mean come on now.. The phone needs to sell well, and/or the HUB needs to be released to more Android devices before WhatsApp would ever allow for integration. What the heck else would you expect? They keep their API closed like a vault. You have to earn their integration by having enough users and them requesting the functionality. It makes perfect sense that given this thinking, WhatsApp doesn't want to waste their time unless it would help bring in enough users and/or be useful enough to a large portion of existing userbase. It makes sense, can you really blame them?

There's a reason there aren't any 3rd party apps in the Play Store trying to mirror the HUB (just an email aggregation app isn't the same as the HUB), because Android doesn't offer enough API's (yet) and more importantly, getting all of the apps on board is a tough thing to do. But a company like BlackBerry is someone who is large enough to possibly influence Android enough or be given special access to API's because they are helping Google right back with security and securing Android.

TL;DR: So is the HUB a "mess"? It has been a mess on BB10 for ages. There are little quirks to it here and there, but it has been manageable and extremely useful. For a BB10 user going to Android, yes, the HUB won't be as feature rich, (and may be seen as "a mess" due to duplicate notifications and missing integrations from what they are used to), but for an Android user moving to this device, the HUB will be the best damn email aggregation app available and the ONLY social/messaging/email/etc. app available on the Google Play Store. So what do you expect?

Again, you have to think **who** this device was made for. It was made for Android users who want to experience a physical keyboard and BlackBerry productivity enhancements. It wasn't necessarily meant for a BB10 user to now have the best of both worlds (apps and all the exact same functionality right out of the gate). BlackBerry is trying though, it's unfortunately much up to other devs opening up their API to BB and Google giving more API functionality to Android. BlackBerry has their hands tied a bit."

Ngoài ra, các ứng dụng của bên thứ 3 sẽ không cần phải "viết lại" như vnbb nói. Chỉ cần họ cấp API cần thiết cho BB để BB code thêm vào Hub for Android là được
