I just got my new Galaxy S4 last week after over two years of living on an HTC Evo. The Evo was a good phone, but ultimately aged poorly – becoming slow, lacking new OS features, and a short battery life that became increasingly irritating.
With half of its built in memory already used for new whiz-bang features that I don’t really need (e.g. eye-tracking scrolling that never really works), I’m thinking the S4 may also suffer the same flaws. In the mean time, however, the most noticeable thing is that Google and Samsung have raised the creepyness factor a notch. The phone knows where I live (by tracking my location), and even has a “feature” where it automatically “remembers the locations where you spend the most time and turns on Wi-Fi when you are near those places.”
This is called “SmartMode” and it’s my new pet peeve (there’s not enough documentation to tell whether it is a Samsung or Google “feature”). What’s interesting is that it doesn’t just turn on WiFi for locations where you have previously connected – it turns it on anywhere you have high dwell time. So for example if you are in your office, and your office doesn’t have WiFi, the S4 will turn on WiFi anyways. No matter how many times you turn it off, it will turn it back on seemingly every five minutes.
To disable go into Settings -> Connections -> Wi-Fi -> Smart mode.
