Hey Jon. This is a common problem on the ZTE Warp. Try to remember if you installed an app prior to the crash. Remove that app and see if the issue gets fixed. You can also reset your phone back to factory settings but remember that all your personal information and downloaded applications on your phone will be erased after the reset.
Resetting Your Phone
1. Go to Settings > Privacy.
2. Tap Factory data reset.
3. Tap Reset phone. Tick Erase SD card if you want to erase the memory card.
4. Tap Erase everything.
Another solution is doing a firmware update.
Go to Settings > About Phone > System updates > Update firmware
