[Other SmartWatches] Student613:
I seem to have found way to power up and down the phone/watch, such that the watch does not give me any problems.

There are several user guides on Mediatek based smartwatches online that give useful information. For example the "Veezy Gear Smart Watch User Guide" is full of tips and tricks. It notes: "The watch features Bluetooth V3.0. Most phones nowadays are V4.0 and up, and majority of them are backtrack compatible. However some phone’s Bluetooth are not very friendly to lower version Bluetooth..." I think the Sun S2 watch is also Bluetooth 3.0

Some other "unboxing" notes of mine:

1. A USB plug is connected to the watch by means of a magnetic adapter. However, when the adapter is not attached the USB signals (including power) are exposed on the bottom of the watch. If you have a metal watch band, it is theoretically possible for the band to short out these connections. I guess whenever a watch with metal band lays around, it should have the USB magnetic adapter attached.

2. I assumed that the USB signals exposed on the bottom of the watch were used for the ECG, to collect electrical signals from the body. Brilliant, I thought. However, this doesn't seem to be the case. The "ECG" is really just a continuously running version of the heartbeat detector. The graph displayed on the ECG screen is just for decoration and is always the same. Maybe some future software release will work? ;)

3. I had seen written in other places that the "UV sensor" is just an approximation of the amount of UV radiation based on the time of day. On the No. 1, website it says "UV Feature Support in Future" which is plausible, because the "flat tire" blank part of the display on higher end watchs is the place where a UV Sensor is placed. If some developer is reading this, a measure of the amount of yellow light to the camera would be more useful indicator of solar radiation than time.

4. The heatbeat seems to work well compared to a real measurement of hearbeat. However it is limited to 99 beats per minute. If you heart rate is higher than that, the watch will give an error message (and perhaps you should see a doctor) ;)

5. On my phone, I find that the MediaTek SmartDevice apk is a CPU and Bluetooth glutton. (My phone, actually 9.7" tablet, is about 3 years old so your mileage may vary). If I have a Bluetooth Mouse and Keyboard attached and then connect to the watch, the mouse moves *very* slowly and then in a couple of seconds disconnects. And the keyboard has about a 1 second delay for every key pressed. When I want to use the smart watch, I uncheck "Input Device, use for input" on my phone's USB screen,the Mouse and Keyboard, and check "Phone audio" and "Media audio" for watch. When I want to use the tablet as a workstation, I do the reverse. I also need to set the phone to silent and the watch to general, and the reverse depending on which device I want to hear ring.

6. Power consumption. On the watch, setting "Power saving" to ON, turns the display to its most dim position and slows down the Bluetooth (my Bluetooth keyboard works a bit better, see above). If I enable "Wake-up gesture" in "Motion" menu, turn "Power savings to ON", turn "Pedometer" to ON, turn "Anti-Lost" to ON, and get about 10 calls & 100 notifications a day, and am sparing on using features like "hearbeat" then I get a full day on a single charge.

7. Bluetooth range is better than I expected. I get about 50 feet (two rooms) from where I place my phone/tablet. I turn on "Anti-Lost" to ON so that I will be notified when out of range. When I get back into range it often reconnects. If I suspect it didn't reconnect, I go to "Bluetooth", select "Search new device", select my phone and click "connect". Also, if I am having bluetooth phone book problems (see below), I find that "disconnecting" and "connecting" phone seems to fix things.

8. Sound volume and quality is better than I expected. I have no problem listing to phone calls, music or other audio material. The music is actually enjoyable. It is fun to hear the GPS come through my watch. This would be great for jogging/bicycling. However when driving, I do not find volume sufficient for phone calls. I use the button to the switch call to my phone/tablet which when I am driving, which is functioning as a GPS.

9. I can't get the "Flip to mute incoming (calls)" in "Motion" menu to work. So I don't know to ignore an incoming call.

10. I can't get the "Looking phone" (Find phone) feature in "Motion" menu to work. It always says "cannot find phone" even though bluetooth is working fine.

11. Phonebook barely works for me. I have a large complex phonebook, multiple entries, multiple apps (skpye, linkedin, etc) so your mileage may vary. When I try find a name it will find the phone entry for a name 2 or 3 positions earlier in the list. I noticed that there is a bluetooth phonebook apk on Google Play Store that says it "fixed many of the known issues in BDAP" (Bluetooth phone book and dialer). I haven't tried that app yet. Instead I reduced my phone book to about 20 entries and it works reasonably.

12. Manage applications. The phone doesn't run android per se, but runs a version of RTOS. Applications are called "LinkIt" and have the extension VXP. I really, really hope this will be developed in future firmware upgrades.

13. Memory: There is 500K (=1/2 MB, =0.005 GB ) free on watch. This gives 5 mins of audio recording or 8 seconds of video recording, or a dozen or so pictures (I did't measure). I haven't opened the watch yet to see if there is any hope of connecting an sdcard for additional memory.

14. File Manager: I have found no difficulty in looking at files on the phone or sending them to the phone/tablet via Bluetooth. Also if I connect the USB to the watch and the other end to a PC, the watch prompts me for "Mass storage" and I can see all the files on the watch. The watch also allow me to select "COM Port" but I can't figure out what that is for.

15. Touch screen. Difficult to swipe at first, but I am getting better at it. However, I would think that buttons to scroll rather swiping would make more sense on this size watch. Forget about dialing a number when you are driving (which is probably a good idea).

Bottom line: Its good enough for what I need: a remote dialer for my tablet so I don't have to lug it around. The health things are great. And it looks so cool. (That makes up for all my phone conversions being "on speaker" now, who knows maybe less phone radiation?). For me, to have a phone/tablet as a workstation which sits in my kitchen or office, while I answer calls with my watch is the best arrangement. I hope this gets developed more.
