But the long awaited time for update was wasted as the device started behaving abnormally with two many issues.
The issues are :
- Black screen during calls ( Proximity Issue )
- Unable to sync Google data/GPS Force close/ Unable to download apps
- Low Sound
- Slow phone/ Lags in transitions
- Heavy battery drain
- Issues while gaming
- Heating problem

Due to these problems, users are unhappy with Lollipop and want to get back to old CM 11 ROM based on Kitkat. But the major problem is that if you have updated your device to official Cyanogen OS 12, then you CAN NOT DOWNGRADE at all. That's because Lollipop is a 64-bit OS and KitKat is 32-bit OS. So if someone tries to downgrade then they will brick their device.
To overcome this problem, a senior developer in XDA has given a solution that will help to flash your device to stock kitkat version.

7. After reboot wait for a while. Voila! Your device should be running on KitKat.
This is an easy way and shouldn’t take much of your time. After downgrading to CM11 you might soon get the OTA for Lollipop that you can simply ignore if you don’t want to install it.
