When I am in a group chat and am on a wifi network the messages never actually are delivered to my phone, i just get a little bubble that i can click that makes my phone download the message. When this happens ill get a whole bunch of undownloaded messages piling up and my phone keeps trying to process them i assume so it heats up to an extreme level. I was wondering if anyone else has this issue with messages not downloading over wifi and if this causes there phone to heat up a lot too, this also causes my battery to drain extremely fast. I just tried downloading the google messenger app (not hangouts) to see if this problem would be solved and it still isnt helping. And yes all my other apps are working on the wifi so its not an issue with the wifi.
