ZTE Fury User Manual

Sorry, Public Mobile ZTE N850. Will it work on the 4G network?

It won't. ZTE Fury (N850) doesn't support 4G(LTE) networks.

I'm sorry, but which phone is that n580?

Hi, May be u need to try with different battery due to poor battery or troubleshoot your device by turning off the phone,Press and hold power key and vol+ key simultaneously for about 5 to 10 seconds until the screen goes to black and several blue sentences will appear.reboot system now,apply update from SD card,wipe data/factory data reset,wipe cache partition.Choose reboot system now after few seconds the phone will reboot normally.Before you perform troubleshooting backup the information to SD card.

Hi Zilda. I just found out that this is a known issue with ZTE Fury. A lot of ZTE Fury users has been having the same problem as you and there is currently no fix to this. If you're still in the 14-day trial period, you should return your phone and get something else. If you're beyond the trial period, the only hope you've got is if ZTE or Sprint releases a software update that will solve this issue. I hope they do. Good luck!
