Is it normal for a pic to take 20+ mins to send via texting? Takes text messages several mins at times also. I've tried with strong Wi-Fi and also without (in a location where I've got 3 solid bars of service). Since this device has lousy battery life to begin with, this is a huge bummer. Pretty disappointed with both the device and service since switching from Verizon with an iPhone.
I would suggest saving any message threads you need using an app like SMS backup and restore and then removing all message threads. This may take quite some time however it should free up some of the available resources and you should be able to send faster after doing so.
