Hello, here is my situation,
I would like to check for email when my data transfer is active, I use an app that disables data transfer when my screen is off, and it turns it on, when I unlock my screen.
Now this works superb, but if I have IMAP Push enabled, and it checks for email every 5 min, and I wonder if I disable that, and only enable to check for email every 30min, would it still check for mail when I unlock my screen, or would I have to be lucky that phone would be unlocked, when that 30min cycle happens?
