OnePlus has started rolling out a new system update, version B50P01, as part of its regular update cycle. The update focuses on system stability and adds a few small features aimed at improving everyday use.

The build carries version numbers BRB1EX01 for phones and BRB3EX01 for tablets. The rollout began on March 16, 2026, and will continue in phases until around March 31. As with previous releases, it is being pushed in batches. Users also have the option to manually check for the update and install it without waiting for the full OTA rollout.

One of the main changes is in Content Portal, available on OxygenOS 16 and select models. The feature now supports app clones. This allows users to duplicate apps and manage content more easily across different accounts or use cases.

The update also brings a change to OnePlus Share on OxygenOS 16 devices. A new option called “Automatically open received files” has been added. Users can choose whether shared files open immediately after being received or stay saved for manual access. This gives more control over how files are handled during transfers.

Alongside these changes, the update includes general system stability improvements. OnePlus has not listed performance upgrades, but the focus is on making the system more stable and reliable during daily use.

The rollout covers a wide range of devices across different OxygenOS versions. Devices on OxygenOS 16 include the OnePlus Open, OnePlus 15 series, OnePlus 13 and 13R, OnePlus 12 and 11 series, OnePlus Nord 5, Nord CE5, Nord 4, Nord CE4 series, Nord 3, and the OnePlus Pad 3, Pad 2, and Pad.

Devices running OxygenOS 15 and 16 include the OnePlus Nord 3 and OnePlus Pad. OxygenOS 15 also covers the OnePlus 10 series and Nord CE3 series. OxygenOS 14 includes the OnePlus 9 series, OnePlus 8T, Nord 2T 5G, Nord CE 2 Lite 5G, and OnePlus Pad Go. OxygenOS 13.1.0 reaches the OnePlus 8 and 8 Pro, while OxygenOS 13.0.0 includes the Nord 2 5G, Nord CE 2 5G, and Nord CE 5G.

OnePlus says this update follows its usual version pattern and does not change device performance or core system behavior.

Xiaomi has introduced the Desktop Speaker Pro Set to the global market, with Singapore being the first to receive it. The system is priced at SGD 139 (around $109) and comes with a wireless subwoofer. It was originally launched in China in September 2025 under the name Redmi Desktop Speaker 2 Pro.

The main speaker uses a four-driver setup with two 10W racetrack drivers and dual passive radiators arranged horizontally to deliver a wider stereo field. It is angled upward at 53 degrees to direct sound toward the listener and improve clarity across a desktop setup. Xiaomi pairs this with a wireless subwoofer that features a 96mm long-throw driver and a tuned acoustic port. It can reach frequencies down to 60Hz and uses an independent power supply for stronger bass output.

The main unit and subwoofer connect over a low-latency 2.4GHz wireless link for synchronized performance. Audio processing is handled by a DSP system with a full digital signal chain and amplifier, designed to deliver low noise and a high dynamic range. There are five EQ modes available: Music, Bass, Vocals, Game, and Movie. The subwoofer automatically adjusts based on the selected mode.

Connectivity options include USB, Bluetooth 5.3 with A2DP playback, and AUX input, allowing use with computers, smartphones, and tablets. The system also includes a built-in microphone with acoustic echo cancellation for calls and meetings. A 3.5mm microphone input is available for external microphones.

The design features a metal grille and RGB lighting. There are 24 LEDs in the main speaker and 5 in the subwoofer, with six lighting effects available. Controls are handled through a side-mounted knob and two top buttons for volume, sound modes, input selection, and lighting.

The main speaker measures 51.1 x 7.5 x 7.5cm, weighs about 960g, and runs on 12V 3A power. The subwoofer measures 15 x 15 x 21.9cm, weighs about 1,308g, and runs on 12V 1.5A. Both operate within a temperature range of 0°C to 40°C.

OPPO Find X9 Pro users can now install Android 17 Beta 2, with OPPO releasing the latest developer build based on Google’s Android 17 Beta 2 along with the latest Google Mobile Services package.

This release is limited to the Find X9 Pro. No other OPPO devices are supported at this stage.

OPPO says this build is meant for developers and advanced users. It is not a stable version and is not recommended for daily use. Users who are not familiar with flashing ROMs or handling beta software are advised to wait for the stable update.

Installing Android 17 Beta 2 will erase all data on the device. This includes apps, photos, music, and documents. OPPO requires users to back up everything before starting the process. The backup can be done through Settings, under Additional settings, then Back up and migrate, followed by Local backup. The backup file is saved in the device storage under the ColorOS backup folder. Users must copy this backup to another device, as it will also be deleted during installation if left on the phone.

There are several known issues in this beta version. OPPO Interconnection features and touch response may freeze or fail in some cases. System apps and settings may show display issues or visual bugs. Users may also face screen flickering, app crashes, or apps becoming unresponsive. Third-party app support is limited, and some apps may not work properly.

Since this build uses Google Mobile Services, some OPPO apps that overlap with Google apps may not be available after installation.

OPPO also warns that this is not a simple install process. There is a real risk of bricking the device if something goes wrong. Users should only proceed if they fully understand the steps.

Xiaomi has brought the Redmi A7 Pro to Europe, with Italy being the first market after its earlier launch in Malaysia. The phone had already appeared on certification listings last month, so this release was expected. It runs on HyperOS 3, which is now making its way even to Xiaomi’s budget devices.

The biggest focus here is battery life. The Redmi A7 Pro packs a 6000mAh battery, which should comfortably last through a full day of regular use, including streaming, browsing, and calls. Charging is limited to 15W, so it is not fast, but that is in line with what you usually get at this price.

The display is a 6.9-inch IPS LCD panel with a 120Hz refresh rate. That is a noticeable upgrade in this segment, where many phones still stick to 60Hz or 90Hz. Scrolling and general navigation feel smoother, even if the panel itself is still an LCD.

Under the hood, the phone uses the Unisoc T7250 processor built on a 12nm process. It comes with up to 8GB RAM and up to 128GB storage. In day-to-day use, this setup is enough for basic tasks like apps, social media, and light multitasking, but it is not meant for heavy gaming.

On the camera side, Xiaomi has included a 13-megapixel dual rear setup with AI features, along with an 8-megapixel front camera. The AI processing helps improve shots in different lighting conditions, which is important for a phone in this category.

Design is another area where Xiaomi is trying to stand out. The phone is available in Black, Blue, and Green. An Orange variant is also available in other regions. It has a wavy texture on the back, which gives it a slightly different feel compared to the usual plain finishes.

Pricing in Italy starts at €129.90 for the 4GB RAM and 64GB storage version. The 4GB RAM and 128GB model is priced at €149.90. Both variants are available in Black, Mist Blue, and Palm Green.
