I am having problems with my Warp since I bought it in Feb. Every time I download any kind of app from the app store, I never receive phone calls. I can make calls but half the time I don't receive them. I have tried rebooting, factory reset and even a hard reset to no avail. I have tried to uninstall the apps and reinstall them but still having problems. I have contacted ZTE and Boost Mobile and they could not help me. If anyone can help, I would much appreciate it.
