📱 Oppo Bubble: Smart selfie screen that needs Qi2 to realize its full potential
Quick summary
Oppo announced a unique innovation in the smartphone world, the Bubble device, a small detachable second screen dedicated to selfies that works wirelessly and can control the phone’s camera remotely. This innovation offers a new and enjoyable user experience for Oppo phones, especially with support for taking selfies using the phone’s rear cameras through a circular OLED interface measuring 1.73 inches. But despite its advantages, there are clear technical weaknesses such as poor support for Qi2 magnetic wireless technology, which limits the stability of Apple Bubble on phones and makes the user experience less seamless.
⚙️ What is Oppo Bubble?
Oppo Bubble takes the form of a small device resembling a disc, 7 mm thick and weighing about 27.5 grams, equipped with a circular touch OLED display. This device can be connected to the phone wirelessly, and it has a battery with a capacity of 550 mAh rechargeable via a USB-C port.
Bubble is a more practical and flexible miniature version compared with similar devices such as Insta360 Snap, and it allows users to capture photos and videos using the phone’s rear cameras via remote control. The device’s advantage is that it can be used in several ways, either magnetically attached to the back of the phone or separated as a remote control that works at a range of up to about 33 feet.
Why does this matter?
Having a smart, movable second screen allows for a more comfortable and freer shooting experience, especially for selfies that rely on the higher-quality rear camera rather than the traditional front camera.
🔋 Battery and connection performance
The battery inside Bubble has a capacity of 550mAh; the company does not provide precise details about operating time, but it is likely enough for a moderate period of use before recharging. The connection is wireless and does not require cables, and the device includes a USB-C port to charge the battery directly.
Technical points worth noting:
- There is no information about the number of hours of operation, leaving room for criticism in terms of expectations for battery longevity.
- The wireless connectivity feature ensures easy mobility and no reliance on annoying cables.
Quick takeaway
Despite the uncertainty around battery life, Bubble’s design focuses on simplicity and ease of use while providing a true wireless experience.
📸 The screen and practical functions
The circular screen measuring 1.73 inches appears effective as a selfie display surface, but it is not ideal for framing images because it conflicts with the classic square aspect ratio of photos or video. In addition, the screen supports touch but lacks tap-to-focus.
Bubble allows the user a simple zoom that can be controlled via the basic buttons, and there is a single button on the device that functions as both the power button and the shutter control when taking photos.
Important point
Lack of tap-to-focus support reduces fine control during shooting, which may affect the quality of the selfies the device relies on.
🧲 The magnet problem and the absence of Qi2 technology
The biggest problem users face is the way Bubble is attached to the back of the phone. Since Oppo devices have not yet adopted the Qi2 wireless magnetic standard, the current setup requires an awkward workaround: a magnetic ring that the user manually sticks to the back of the phone.
This ring is considered weak and does not hold Bubble securely, which may cause it to slip and fall easily. Even when using an official magnetic case from Oppo, pressing the screen or the shutter button still causes the device to move away.
What changed here?
The lack of Qi2 support means that Oppo and most Android companies have not adopted a unified standard for wireless magnetic connectivity, opening the door to inconsistent and inconvenient solutions for users.
🤖 User experience and additional features
Bubble is deeply integrated with Oppo’s camera app, which allows it to be separated from third-party apps such as Instagram. It stands out because it can work even when the phone is locked, speeding up the photo-taking process without needing to unlock the phone first.
The interface includes 3 brightness levels, the ability to lock the screen, and a number of drawn background options that focus on the entertainment side, such as displaying animals or animated cartoon characters, but they remain purely entertaining and not interactive.
Why does this matter?
Focusing on integration with the official camera app enhances security and privacy, and reduces the likelihood of sensitive content appearing on the Bubble screen.
💸 Price and available markets
Oppo Bubble comes at a price of 129 euros (about 150 dollars), which is almost more expensive than its competitor Insta360 Snap, sold for around 80 dollars. Bubble’s use is currently limited to Oppo phones, such as the latest Reno 16 series, and some Reno and Find X phones.
This exclusivity limits the product’s audience, but it provides an integrated experience with Oppo devices. However, users are expected to see similar technologies from other manufacturers soon.
Bottom line
The price is relatively high compared with alternatives, but the build quality and wireless ease of use are worth the extra cost for those who own compatible Oppo phones.
🌟 Future vision: Are we waiting for Qi2?
The biggest question remains: will Qi2 be the future of magnetic attachment and pairing for smartphone accessories? Qi2 provides a unified standard for charging and wireless magnet specifications, and this will make attaching devices such as Oppo Bubble safer, more stable, and more professional.
Until Android companies adopt this standard more widely, the experience of attaching something like Bubble will remain limited and prone to flaws, unlike the accelerated solutions used by some of its competitors.
Why does this matter?
Moving to the Qi2 standard could greatly improve the user experience and the durability of accessory devices, and unify tech markets instead of the isolated solutions used today.
Article conclusion
Oppo Bubble is an innovative idea with great potential to improve the selfie experience and control the phone camera wirelessly through a small smart second screen. Its strength lies in its simplicity and compact size, in addition to its deep integration with Oppo phones, but it lacks important technical pillars such as Qi2 support to magnetically attach the device in a safe and comfortable way.
Despite its high price compared with competitors such as Insta360 Snap, it offers a practical solution for Oppo fans, and there is no doubt that this idea will advance as phone specifications and technologies evolve, especially with the adoption of unified standards for wireless magnetic attachment and charging. Until then, Bubble will remain a distinctive device, but it needs improvements in attachment and magnetism to reach the best possible user experience.
You can think of Oppo Bubble as a first step toward turning the smartphone into a more integrated platform with smart secondary accessories that open the door to new and more dynamic experiences in the world of phones and photography.
