📢 OnePlus has released its latest OxygenOS FAQ for January 2026, offering clarity 🔍 on a range of user concerns regarding bugs 🐛, system behaviors, and the update roadmap 🗺️.

🖥️ Display and Performance Clarifications

One prominent issue reported by the community involves screen flickering ⚡, green tints, or colored lines appearing specifically during WhatsApp 💬 video calls 📹. OnePlus has confirmed that the root cause has been identified and traced back to the application itself. Consequently, a resolution relies on a future update from WhatsApp developers rather than a system patch 🛠️.

Streaming performance 🎮 has also been a topic of discussion, with some users noting frame rate drops when casting their phone screen for live streaming. OnePlus acknowledges that this affects specific devices and has an optimization plan 📈 in the works for a future update. In the interim, users can mitigate the issue by utilizing the game casting feature within the Game Assistant 🕹️. By casting via O+ Connect—either through a QR code scan 🏁 or a USB connection 🔌 to a PC 💻—the system switches to a game casting mode that offers significantly better stability.

There is also clarity regarding customization ✨. OnePlus confirmed that certain device models simply do not support live wallpapers 🖼️. Currently, there are no plans to retroactively add compatibility for these devices 🚫, so users are encouraged to keep an eye on official channels for any potential changes in policy.

🔋 Understanding Battery Charging Logic

The company also took time to explain a common point of confusion: why battery usage stats don’t reset immediately when the charging icon hits 100 percent 💯. The charging process occurs in three distinct stages: fast charging 🚀, constant charging ⚡, and finally, trickle charging 💧. The UI displays 100 percent before the battery is actually fully saturated. The trickle charging phase takes approximately 20 minutes to complete, topping off capacity lost to self-discharge. The system is designed to reset usage time only after this final stage is finished to ensure accuracy 🎯.

✨ Feature Enhancements

Regarding productivity tools 🛠️, the AI Enhance feature 🤖 is now easily accessible. Users can simply open Notes 📝, tap the plus icon, select “Scan document,” 📄 and choose AI Enhance to optimize their files. Additionally, privacy controls 🔒 have been refined. The Private Safe search function has been upgraded, allowing users to search through private images, videos, audio, and documents directly via Settings > Security and privacy > Private Safe 🛡️.

🚀 System Update Rollout

Finally, OnePlus confirmed the rollout schedule 📅 for the OxygenOS B30P01 update. Distribution began on January 19, 2026, and is scheduled to conclude by February 5. This specific build is primarily focused on implementing the search improvements within Private Safe 🔍.
