Fitbit Sense Keeps Restarting

[TG26]

I’ve only had my Sense for 2 days but it has restarted no less than 15-20 times during the two days. I’ve tried manually restarting it and changing the clock face. Nothing seems to help. I notice it because it vibrates slightly during the restart. Is anyone else experiencing this issue?

while on a run yesterday, I tracked the exercise like I always did with my Versa 2 and during the exercise, the Sense vibrated many times. I have it notify me every mile but I only went 2 miles and received 10 or so notifications. When I looked at the Sense, there was no notification on the screen. 

I don’t know if these two things are related, but they are irritating. 

Thanks

Yes!!! Me too!!! Especially when I tried syncing it with the app. It says GPS connecting and it just restarts. It happened 4 times and then I just gave up >=\

I had the "restart" problem for many months. I fiddled for months with firmware updates, changing settings, etc. Nothing helped. I sent it back and they replaced my Sense, that process took nearly a month. The new one works fine. My advice, send it back. You'll lose your Sense for a month but then it will work fine.

Did your problem start happening right out of the box? My Sense is just under a month old and the first few weeks have been ok aside from some (unfortunately acceptable) glitches.

My random reboots just started a couple days ago and I hadn't really changed anything. Same settings from prior. Even my clock faces haven't changed lately. I'm not sure if there was a firmware update that happened to cause this.

And my problem isn't just random restarts. I get stuck in random reboot loops. First time I tried a soft reset with the charger. Earlier I did a factory reset. 

[alvinpatrick]

Were you able to change back to your clock faces with no issues after the factory reset?

Well, my Sense is now stuck in a reboot loop.  Endless sequence of a momentary vibration, Fitbit logo, blank screen, vibration, logo, blank... about 8 seconds for a cycle.  I can't even get into the watch to do a hard reset.  I've only had it for a couple of months.  NOT a good experience.  Yo, Fitbit!!!

Well, kudos to Fitbit for not wasting my time with endless troubleshooting - they went quickly to the replacement option.

06:06:39 System: Thanks for waiting. Please provide as many details as you can so we can get you back on track.
06:06:49 Agent: Jhorman C.: Hi! I am Jhorman from Fitbit customer support. Tell me, how can I be of your assistance today?
06:07:33 Don W.: Hello, Jhorman. My Fitbit Sense is stuck in an endless reboot loop. It vibrates briefly, displays the Fitbit logo, goes blank, vibrates, logo, blank...about every 8 seconds.
06:08:21 Agent: Jhorman C.: I'll be more than happy to assist you with the screen or internal issue of your Fitbit Sense.
06:08:35 Agent: Jhorman C.: May I know if you have done any troubleshooting before contacting us? I wouldn’t want to advise you on something you’ve already done
06:09:39 Don W.: I've tried longpressing the button to try to get an orderly reboot. I have put it on the charger and taken it off. I've searched the community forums as well as the Internet at large to try to find a way to do a factory reset other than from the menus (which I can't reach because the watch doesn't finish booting), without success.
06:10:41 Don W.: (And I've dragged my ancient Blaze out of my drawer to use in the meantime.)
06:12:15 Agent: Jhorman C.: I appreciate you have tried some troubleshooting steps earlier
06:12:30 Agent: Jhorman C.: Let's try to change clock face on the Fitbit app in order to see how it reacts
06:12:47 Don W.: The watch is not completing its reboot. It is not talking to the app.
06:12:59 Don W.: but I'll try it
06:13:03 Agent: Jhorman C.: Thanks
06:13:46 Don W.: "Unable to connect to device"
06:14:58 Agent: Jhorman C.: Thank you for trying it!
06:15:14 Agent: Jhorman C.: Since you have exhausted the troubleshooting steps for this situation, your case will be reviewed by our warranty department in order to confirm your current options.
06:15:20 Agent: Jhorman C.: Could you please confirm your country of residence and the retailer where the device was purchased from?
06:15:43 Don W.: USA and Amazon. It is still in its return period. I'll send it back to them.
06:16:17 Don W.: From what I see in the forums, this is a very widespread problem with this device. Has there been a fix or should I move on?
06:17:03 Agent: Jhorman C.: We should move on
06:17:22 Agent: Jhorman C.: However, is your phone running the latest version?
06:17:23 Don W.: No, I mean can I expect a replacement device will work better or should I buy a different model?
06:17:43 Don W.: Version of what, the Fitbit app?
06:17:59 Agent: Jhorman C.: Oh I see, it is not a normal issue, it sould not happen
06:18:06 Agent: Jhorman C.: Nope, OS version!
06:18:16 Don W.: I'm running the latest my phone will take.
06:18:33 Agent: Jhorman C.: Perfect
06:18:41 Agent: Jhorman C.: Please allow me a few minutes!
06:19:30 Agent: Jhorman C.: Great! You've been confirmed as eligible for a replacement. I have just sent you an email with the replacement options. As soon as you get it, you'll need to log in to review them.
06:19:48 Agent: Jhorman C.: By the way, after our chat, you will receive a very quick survey.
06:20:00 Agent: Jhorman C.: Is there anything else that I can assist you with?
06:21:57 Don W.: Thank you. I'm arranging the replacement through Amazon. If the new device experiences a similar failure, I will shop other brands. Since this is a very widespread problem, Fitbit should have recalled the Sense!
06:22:26 Agent: Jhorman C.: Thank you for your feedback!
06:22:33 Agent: Jhorman C.: Have a great day!
06:22:38 Agent: Jhorman C.: Stay safe! Feel free to end the chat whenever you're ready by clicking on the option in the chat window. Thanks for contacting Fitbit.
06:22:54 Don W.: Have a good day. I do not envy your job right now 🙂
06:23:00 System: The chat is ended.
06:23:00 System: Don W. left the chat.

Did you get it to resolve? 😞

[GeraldB88]

Yes. I got a replacement unit and so far it has been good 🤞

[Jzeser]

I, too, had the same issues... blank screen, logo, blank again. This was happening every minute for several hours. I tried the hard reset, checked to see if I had any updates, etc. None of that worked.

I contacted the help chat and was instantly told I was being referred to someone who would contact me via email. I am guessing it is because my watch was purchased from a friend and not under any warranty. 

The email simply offered me a discount on a new device, since I did not have a warranty. I decided I would attempt the factory reset. I would rather do that than rush to buy a new watch. 

IT WORKED! If yours is like mine, you have to move quickly.

Good luck.

Mine has been restarting itself without it being on my wrist so wearing it is not the issue. Is there a bug fix for this? Anyone know what the latest version is?

[IBDWEBMASTER]

Mine was working perfectly for 5 months before these problems so I didn't have this problem out of the box.

[IBDWEBMASTER]

I reset it to factory setting, removed it from the app and started it all from scratch and it seems to be working now. Hope this helps...
