🥈 2nd Place: Stock Android 8.0 Oreo – Beta Build C01

Version: Z999_O_Beta_C01
Android Version: 8.0 Oreo
Best for: Security patches and notifications

ZTE never officially released Oreo for the Axon M, but a leaked beta exists. It is buggy, but if you need newer security patches (2018 vs 2017), this is your only stock option.

• Pros: Picture-in-picture mode, notification dots.
• Cons: Occasional touch unresponsiveness on secondary screen; battery drain 20% worse than Nougat.

Issue 3: IMEI = 0 (No cellular signal)

Cause: You flashed firmware from a different model (e.g., Z999 vs Z999-US).
Fix: Re-flash the correct carrier firmware using QPST. Restore from a QCN backup if you made one.

2. Custom ROMs (LineageOS / AOSP Ports)

There have been attempts by developers to port newer versions of Android (usually LineageOS 14, 15, or 16) to the Axon M.

• Why people try it: To get a "cleaner" Android experience without ZTE bloatware, or to get newer Android security patches.
• Why it is NOT the "Best":
  • Broken Camera: The camera drivers are proprietary. Custom ROMs often result in a non-functional camera or very poor image quality.
  • Broken Dual-Screen Logic: The hinge sensor drivers are difficult to code. On many custom ROMs, the second screen turns black when you open the phone fully, or the scaling is wrong.
  • Battery Drain: Without ZTE’s specific power management for the dual-battery setup (two batteries inside to balance the weight), custom ROMs often drain power faster.
