Hi, I've had my S6 for 1 year almost and I'm not sure if I should upgrade the software to the latest upcoming Android 7.0 when it's available. In the past, when I upgraded to Android 6.0 my S5 started going nuts so I had to change my phone because it became unusable. Anyone here has the current Android 7.0? How is it? Does it have bugs? Is it really worth it?
