I took my cell after the update and reconiced that my battery life is going fast away. First I where thinking is about updating all apps and so on. But no f..... way, even after over a day. Still my cell uses battery for laying on the side and display is off!!!. Took my cell at 8am away from the charger, 3 house later I am at 75% battery life. I only was using it for 20min other then it was laying on the side and no one touched it. Before the update I used not even over half the battery in a full day, even with playing for like 1 to 2 hours. Now I just can look for the next plugin to f....  charge again. I am very very disappointed and wanna have that problem from Samsung very fast fixed. I am sure many many people have the same problem. Also many themes are not compatible with the calendar, white background and white written day's are not possible to see. I need the calendar for work and it's a very important part for me.  Please fix your issue as soon as possible  ... View more
