I experience serious problems since this week-end with my Vivoactive 4 (see symptoms and details below).
I suspect that it could be caused by a recent SW update (typically the Sensor Hub update that was released à few days after after the 6.90 firware update according to what I've just read).
Is there a way to reinstall the previsous version of the Sensor Hub ?
Or, if somebody has an idea looking at the details below ... because, to date, the watch just gives me the (good) time, connects to the phone, receive the notifications and ... that's all.
Details of problems, background...
- Previsous state : no problemn since about 2 years. Standard usage (run, bike), no apps excepted Spotify.
- Nothing special performed before / after (no apps installed, no config change, no shock .. not even a sportive activity, unfortunately...)
- But : I wonder if there has not been a SW update saturday. Not the entire firmware. Something else (GPS? Sensor ? ...). Unsure.
- Since this WE :
-- the battery falls from 100 to 0 in around 4 hours (instead of ar. 7 days)
-- the heart-sensor-light is off, no values are returned when trying to do any activity
-- the GPS-fix (position) cannot be obtained
-- the reactiveness of the screens is, sometime, slow, or even ineffective. But sometime, looks normal.
-- the spotify was not returning all the items syncrhonized
Tried so far :
- Disabled all notifications
- Desabling / Enabling HR sensor
- Disabled GPS+Glonass to GPS only ... then to nothing
- Removed all Spotify syncs
- Full reset (inc removing all data and apps)
- Called the GARMIN Support, who made me downgrade the firmware to the 6.80 version
- Desabling / Enabling HR sensor again
Note : the support guy was not able to downgrade other SW parts, and had no information about these. It looks also not possible to know/check when an update has been performed on the watch. That sounds really unprofesionnal to me. Such things are quite baseline when you handle software, especially embedded ones !
