I've this problem with mail application: all my email account aren't in push mode, but in manual mode. If I try to update the emails the first time is all ok. But if I leave the email application in background, when I call it from the task manager and I give the update command nothing: i can see the blue bar in top and only the left arrow near the wifi icon blink and the left arrow is off.But if I close the email application from the task manager, when I reopen it for the first time, it can download all the new email. I tried to reset my z2 and delete internal memory, but nothing seems to change. I have the last firmware.
Thanks to anyone who can help me
