Hello,
Recently I've bought a vivoavtive 4.
I've used it since july and I'm pretty happy to have it, however in the recent days I have real issues with crashing and the touchscreen.
Since I bought it , it was updated to FW 7.80, connected it 2-3 times to my PC and it was never turned off. The lowest percentage on the battery i've ever got was ~4% but I've always charged it when it comes to 15%.
The watch firstly crashed when I started a walk activity with ~15% battery left. I expected to fall down to around 7-10% since i use it actively with GPS turned on, however this happened: When i start walking it crashed without me knowing it, then i've booted the watch and I've continued walking with ~13% battery left, then after another 20 minutes of walking, the watch died totally(it was supposed to have a little more energy left at least). I got only to the triangle with the sports and then turns off. I've plugged it in after I got home and booted it immediately.
Then it crashed another 2-3 times when I was doing walk activities.
The latest example from today is this, with ~50% battery started the activity and it crashed immediately. I've booted it and then started a new walking activity, it worked, passed 2 km of walking and right in the 3rd km for the 3rd autolap, it crashed. Booted it again and had 2,96km. I've resumed it, another crash in the same time, when it reports the 3rd lap at 3rd km. After booting, it became 2,94km and saved the activity right before the 3rd lap notification. From this, i understand that the battery isn't stable to provide power for the vibration, but it vibrated normally when saving the activity, now when I start any walking activity, the watch crashes whatever the battery precentage is.
Another worrying issue is that some parts of the touchscreen arent working at all. For example when I need to enter some data from a set in a Strength exercise, I cannot enter 6 or 9, all other numbers can be entered, but these two cant, the same happens for the quick access menu(the one when you press the upper button for longer).
Is there any way to repair this?
