I bought a LG G3 a few weeks ago and the same day I upgraded to Lollipop via factory reset before updating, then adding my accounts. I haven't had push email on any account since day one and I've read several threads in where it's claimed there's push email on Lollipop, or at least the gmail app. The lack of complaints about this tells me either it works properly for almost everyone, or it doesn't and few people care. I'd like proper push email, like I have on my Z10, but I can't seem to figure out where the problem lies. When I send myself test email the Z10 sounds off as my finger lifts off my mouse button, and then my desktop as soon as my Z10 goes quiet. Sometime in the next hour my G3 receives the same mail. It's the same result whether on WiFi or carrier connection.
