[Samsung Gear 2] mpogr:
Working/non-working summary

Guys, I should probably elaborate on what is and isn't working in terms of integrated Gear/phone functions:

Alarms: don't work, plain and simple. I am in a desperate search for a LOCAL alarm app for the Gear, even thinking about writing one myself!

Making calls: works using dialer, from Contacts and using S Voice. However, the call is always transferred to the Gear first. You can transfer it back to the phone from the Gear or from the phone. However, if you also want to use Bluetooth headset (or in-car), you're out of luck. I implemented a workaround disconnecting the Gear and connecting to the earpiece using Tasker.

Receiving calls: works fine, except the answering device limitation above.

Browsing contacts: works fine. If you tap on the phone number, it makes a call straight away, without asking anything else (with Samsung it might be acting a bit more intelligently asking if you wanted to call or text). If you tap on email address, nothing happens (I'm assuming with Samsung it would allow you to send an email, more on this below).

Browsing schedule: works fine. On Samsung, you can select specific calendars to be displayed on the Gear in Gear Manager settings. On Sense devices like my M8, you can select calendars to be displayed in your Calendar app, this selection automatically propagates to the Gear. You can't change anything in the appointment. Not sure if this is different in any way on Samsung devices.

Messaging: for starters, you need to use stock Messaging app and not a substitute, e.g. Hangouts. Second, you can only send texts, and only to contacts. You can't see received texts (you can see content of received texts if you chose to receive notifications from Messaging app, but this is not the same as with using the texting app, which allows you to browse ALL of the text messages stored on your phone). To send a text message, tap on "Messages" on the Gear. You will see "No messages". If you SLOWLY drag the window from the top to the middle, an option of "Send message" will appear. You can tap on it, then it will allow you to select the contact. Then you will be able to either select a predefined template (I already posted on how to change those) or compose a message from a bunch of emoticons. S Voice doesn't work with non-Samsung Messaging app.

Email: this one simply doesn't work. It totally relies on Samsung emailing app and refuses to work with anything else. You can get notifications about incoming emails if you select "Gmail" and "Email/Mail" as 3rd party notification providers, and these would typically include the sender, subject and a couple of lines of text, but that's it. You totally depend on what your emailing application chooses to put in those notifications. You can neither browse past emails nor compose new ones. I'm assuming email composition on Samsung devices relies on S Voice.

S Voice: this one requires further investigation. As mentioned above, texting and emailing don't work. Web search is not supported either, I'm assuming this is true for Samsung devices as well. Calling, showing weather, appointments and contacts does work, as well as composing new appointments and meetings (but it doesn't send meeting invites if you add attendees to your meetings). I guess more research is needed to figure out what else is working.

Call logs: doesn't work, shows empty log. Again, you do get notifications about missing calls, but you can't browse any kind of call history.

Media Controller: seems to be fully working on Sense 6 devices, regardless of music app (tested with built-in Sense player as well as Poweramp).

Music Player: seems to be working with music stored on the Gear, including streaming to a Bluetooth headset. You can get music onto the Gear in two ways: either copy from the computer over USB or transfer directly from the phone using Gear Manager. I think, on Samsung, you can also play music stored on the phone directly, without prior copying it to the Gear. Not sure why this is a valuable function though...

Voice Memo: seems to be working locally on the Gear. When you finish recording the memo, it gets transferred to the phone and then, apparently, goes nowhere. I'm assuming on Samsung it's integrated with the Memo app and becomes available from there, either in audio and/or in text form.

Weather: doesn't even get installed on the Gear. This means both Weather app on the Gear and Weather watch faces are unavailable. A simple workaround is to ask S Voice "Show current weather", it basically displays the same information.

Exercise apps: there are 4 apps there: running, walking, biking and hiking. The former 2 seem to be working, while the latter 2 seem not to, because they rely on GPS info from the phone which doesn't get relayed on non-Samsung phones. The apps that are working seem to be quite crappy though.

Other fitness apps: Heart Rate, Pedometer and Sleep seem to be working. All these seem to be perfectly synchronising into Samsung account using Fitness for Gear app on the phone.

Editing text templates: Gear Manager crashes when you try to do that. I already published a way of working around this.

Changing watch wallpaper from Gear Manager crashes (it didn't in the previous versions). There is a simple workaround: choose the wallpaper on the watch. You can copy it over to the Gear using your computer over USB.

Gear Software Update crashes once in a while and fails to update the Gear firmware (again, was working fine in previous versions of the Gear Manager): install Kies 3 application on your PC and update your Gear firmware using it.

Find the Gear and Find the Device are working.

S Health doesn't work. Not sure if it has any added value for Gear owners on top of what Fitness for Gear has to offer.

S Voice installed on the phone as a part of this process (to enable S Voice functionality on the Gear) doesn't work on the phone. Not sure it has any value considering what Google Now has to offer.

Once Gear gets disconnected from the phone, it doesn't reconnect on its own (it does with Samsung phones). There is a simple workaround for this using Tasker.

Last but not least: installing apps from Samsung store seems to be working.

That's it more or less. I didn't check "WatchOn" remote control app, but I read somewhere someone tested it and found working.
