Sense stopped syncing

[createpaint]

Got a brand new sense last week. yesterday it stopped syncing. read advice last night which said restart phone and watch. did both. now my sense will not turn back on. using android phone. very worried as watch is completely unresponsive. had almost 90 percent battery when turned off. anyone else not able to turn device on?? for a device that is less than a week old I am underwhelmed by whole experience

The sense has an indent button which takes some getting used to.

try this technique

Worn on the left arm -

rest your other thumb on the arm to the left of the watch

and forefinger on the back of the hand

and do a gentle squeeze of the watch

Squeeze for upto 10 seconds until you feel a faint vibrate or the logo appears

it is a month later and again my watch will not sync with my phone. is this going to be a cyclical problem?

I have a galaxy A9 2018

app version 3.37.1

watch version 44.128.4.17 as seen on app

watch version as seen on watch 44.128.4.17

The watch usually syncs when I plug it in to charge in the morning. this morning it didnt but synced this afternoon when not charging. it does not regularly sync and this renders is functionality reduced. 

Your help so greatly appreciated for an expensive watch that does not work properly.  many thanks

Thanks for the feedback, you are at the latest levels and it should work well.

Not quite sure what the problem is now, are you still unable to turn the watch on, and is it unresponsive?

If its syncing, guess that problem is resolved, however for watch face problems it could be a clock face issue and an alternative clock may resolve it.

If its having problems syncing or staying synced consistently

Try this to disable battery saving.

On the phone check battery optimizations

[the options may be different in your version]

• First go to Settings > Apps & Notification > Special app access
• Click on Battery optimization
• Now press the drop down menu [...] and select “All Apps”
• Click on Bluetooth and then select “Don’t optimize”
• Same with Fitbit
• Next go to Settings > Apps  > Fitbit > Storage
• Clear cache [not data]
• Force stop the Fitbit app

See how that goes.
