I am going to very soon walk away from Garmin as a company and a watch even though until recently I have been very happy with the things that the watch can do. To be fair to both me and Garmin, it is the first smartwatch that I have ever owned, so I don't really have much to compare it to. I don't really need and/or use most of the smartwatch functions because my eyes are not good enough to use functions of something that has font that small on it. My next smartwatch will just be a fitness band, I don't want or need or care about notifications being received from other apps since I can't read them anyway.
The process is pretty simple and straight-forward and unfortunately something that I am having to do on a regular basis these days because it is pretty common that the watch just "blue screen's" and Garmin is actually very aware of this seeing as how they themselves have released video explaining this. Of course comments are turned off because I am certain there are hundreds of thousands of people like me that would love to rip them to shreds in the comments for their repair/service practices.
This happy fella that works for Garmin presents this information as if it always works and is very simple, but I do enjoy that when he himself is performing the action, he fumbles with the watch a bit just like other people would because it isn't very natural to have to hold down a waterproof button on a small item for this long of an amount of time.
It's simple, but doesn't always work
Hold down whatever the power button on your watch is for 15-60 seconds.
sometimes this only has worked for me if the watch is currently plugged in.
This will "soft reset" the watch meaning that your customization settings are still saved but if you were in the middle of an activity when the reset was performed, it might not remember that information, which is annoying.
However, there have been a handful of times that neither of these things have worked for me and there is another method I have used that has worked for me every time. I get the original charging cable, which is USB and plug it into and OUTLET, not a computer. Doing this has, for me, always worked in jolting the watch back to life.
For whatever reason, plugging it into the USB on a computer or the 3rd party cradle stand that I bought for the watch, does not have this effect.
I'm still very upset at Garmin for their policy of not repairing watches beyond a certain date, and even more upset with them for clearly having a company policy of planned obsolescence with their products.
I am currently in the process of investigating a simple Xiaomi fitness band for the future since they are under $100 and don't even offer the smartwatch features that I don't want and do not use anyway.
It is annoying that a watch just starts acting up like this after a certain amount of time and it honestly wouldn't surprise me if there was something built into the components that have a time on them to start doing this after a certain amount of time. I think it was Apple that got busted for this and honestly, there should be civil lawsuits when that sort of thing happens.
