Flex 2 fitbit won't sync with lg aristo

[Chelsb]

I got a flex 2 fot bit last week and am having problems getting to sync with my phone an lg aristo. It only works 25% of the time. It was working if i would unpair it then repair it. It hasn't synced in the last 2 days. Its fully charged. This problem has been happening since  i first got it.  I'm not sure what to do. Any help is appreciated.

Hi there @Chelsb, I cannot start without giving you a warm welcome to our Fitbit Community! In this case we need to consider the LG Aristo is not listed as a compatible device. With these category of mobile devices is not that the app won't work at all but we cannot guarantee the functionality of the App features since is not optimized to run under the specs of this mobile device.

However I would like to share with you these troubleshooting steps for the issue you are experiencing: Having trouble syncing? (here's how to fix this). It would hurt to give it a try to this additional suggest apart from what you have tried already.

Our team is always working to test and add more Android devices to the supported devices list, so keep an eye open for updates and if you are not able to sync, in order to avoid losing your data you can sync via a device listed as supported or using a computer as an alternative.

See you later and hope this helps.

Just got a flex2 that wouldn't sync. Tried troubleshooting myself before calling. Tech support got it to sync but  it never updated again.  Called again and was told to do the same thing previous tech person said to do. Finally was told my phone wasnt compatible with flex2. Then the tech person told me that sometimes it would work and sometimes it wouldn't. Then she decided it was actually the app that wasnt compatible. She kept changing her response between the issue being my phone or the app. Long story short, customer service is clueless and the flex2 is going back to the store tomorrow!
