the first update of my phone is so horribol so very slow and laggy. . I suggest that you reinstall or repair it using Sony PC Companion or Sony Update Services and clear up the internal storage of your phone, do some factory reset and restart (power button + volume rocker up) after updating the phone.. this can minimize log on to your phone. . and also try this go to developers options: transition animation scale: set to 0.5x or off windows animation scale: set to 0.5x of off then after that restart your phone. . just tell me if your phone dont have a camera issues. . coz on my side camera on my phone are not like before. . its slow and dark. .
