I have an HTC M8 converted to GPE, running stock rooted Lollipop 5.0.1. I started having this problem fairly recently, previously everything was fine.
With my screen off, all push notifications are delayed significantly (at least 10-15 minutes on mobile data, 20-30 on wifi). Shortly after I turn the screen on, all delayed notifications start coming through. An interesting point to note is that on mobile data, I don't seem to lose the connection at all (as soon as I unlock my phone, I am connected to the internet) but with wifi, I get connection errors for the first 5-10 seconds.
So far I've tried: factory reset, reinstalling firmware (tried latest Sense, latest stock, and a few older versions), switching to a different ROM (SkyDragon). I'm running out of things to check because I've reinstalled everything that can be reinstalled. I've checked all the silly little things like restricting background data and I don't seem to be using any settings on my phone that could cause trouble. I've also tried several "push notification fixer" apps to no avail.
This is seriously making my phone useless to me, so I would appreciate any help. Thanks a lot.
