Samsung S3 Gear Frontier, Bad battery life, even if you replace it, software problems.

I bought a Samsung Gear S3 Frontier in November 2017. (using my savings) Work well, battery life +-3-4 Days. There was an automatic software update to Tizer 3 in October 2018 and the watch was updated. Since the upgrade, the battery life is between 8-10 Hours. I contacted Samsung and they said I must wait because Samsung is aware of the problem and a new software will be release soon that will resolve the problem. Worldwide forums are talking about the same problem. New software was released - Tizer 4, but still battery life problems. It became so bad that I had to switch off all features and only kept on basic black screen watch. I took the watch to WEFIX and they said the battery needs to be replaced (R700) I told them about the world wide problem and they said if it is not the battery, they will refund me. Battery replaced, two days later battery life is still 8-10 hours on basic settings. Now, just like all the warning worldwide, Samsung wants to replace the main board (+-R1700). The watch was not even 1 Year old (well looked after) when problems started and I’ve being battling with the problem for almost 4 months. Now almost R 2500 later, is it really worth it the repair the watch if it is a software problem. Samsung is forcing consumers to buy new watches, by continuous software problems. Samsung is not taking responsibility for the problem and still try making money of faulty products. Bad Samsung – Sort out YOUR problems and stop *****ING our money.
