The OTA time is different for different phones.
Due to real-time changes involving product batches, production, and supply factors, in order to provide accurate product information, specifications, and features, OnePlus may make real-time adjustments to text descriptions and images in the foregoing information pages to ensure they match the product performance, specifications, indexes, and components of the actual product. Product information is subject to such change and adjustment without notice.
OnePlus Buds and OnePlus phones, when used together, will provide the best experience. They are also compatible with all Bluetooth devices; the longest Bluetooth distance is 10m between OnePlus Buds and the Bluetooth device. Due to the nature of Bluetooth earphones, electromagnetic interference in the area may cause the connection to break. Based on the nature of wireless technology, when the device screen is on and transmits the Bluetooth sound signal at the same time, “delay” may occur in the audio and the video signals, meaning the sound may not synchronized with the picture.
• According to the software update of the phone, the above actions may be slightly modified, and the real OTA content may be different from that of specification.
