Since updating to Nothing OS 4.0, the “Disable default frame rate (60 Hz)” Developer Option no longer behaves as it did previously on NOS 3.2
I am seeing this consistently across multiple devices:
- CMF Phone 1
- CMF Phone 2 Pro
- Phone 3a
Prior to NOS 4.0, this toggle reliably allowed many games to exceed 60 Hz. After updating, behavior is inconsistent. Some apps briefly report 120 Hz, others remain locked to 60 Hz.
Observed behavior (reproducible):
- Display runs at 120 Hz when idle
- Any touch input immediately drops refresh rate to 60 Hz
- Refresh rate returns to 120 Hz once input stops
This occurs in:
- Dead Cells
- Old School RuneScape (OSRS)
The issue persists even with:
- Force peak refresh rate enabled
- Battery saver disabled
- Min/peak refresh rate forced via ADB
Device: CMF Phone 2 Pro
OS: Nothing OS 4.0
Build: Galaga-B4.0-251218-2326
Is this a known NOS 4.0 issue, or has Nothing changed how high-refresh behavior is handled for games? The interaction-based drop to 60hz feels like a regression compared to pre-4.0 behavior. Why can you not disable this hard 60hz cap?
Would appreciate confirmation if others are seeing the same.
