Smartphone cameras have made it easy for the way we capture images and videos. However, one of the common issues users may encounter is experiencing blurry pictures or videos. This issue can stem from different factors, such as a dirty camera lens, poor lighting, or improper camera focus. Understanding these problems can help you achieve optimal image quality and elevate your photography experience. How to Fix Blurry Images or Videos Often, blurry pictures result from the camera being out of focus. The factors that affect the focus blur can be quite intricate. Please verify if any of the following situations apply. Your camera lens may be dirty, dusty or obstructed A sticky or smudged lens can lead to blurry shots. To avoid this, please follow the steps below: Clean the lens with a soft cloth. Remove any obstructions that might interfere with the camera's function, such as protective film, phone cases, and others, then try again if the image clarity improves. Check if your camera's focus functions normally When taking a photo, the camera is usually set to center focus by default. To achieve the best focus, place the subject in the center of the screen. If the focus is still unclear, please do the following: Gently tap the screen on the subject to focus before capturing the shot. Do not press the button until the focus frame disappears, as this indicates that focusing is still in progress. Refrain from using manual focus when recording a video; allow the camera to autofocus. Using manual focus while recording video will lock the focus, and you may need to readjust if you change your phone's position. Poor lighting conditions The camera may produce blurry images due to insufficient light. To improve the camera's ability to gather light, it is recommended to enable the flash or night mode when capturing photos in these conditions to enhance the camera's light intake.

What Is the Difference Between Single and Dual Speakers in OPPO
Applicable products:SmartphonesSystem version:No system version involved
Smartphone speakers are one of the important key components that allow users to listen to music, videos, calls and be alerted to notifications. Some smartphones, like your OPPO phones, come with either single or dual speakers, each offering a different audio experience. For further information, read below. Key Difference: Single vs Dual Speakers Single Speaker A single speaker mobile phone comes equipped with only one external speaker, which is usually located at the bottom or rear of the device. While it can deliver clear sound for everyday use, the audio experience may be limited compared to dual-speaker smartphones. Features: A single speaker mobile device offers a single sound quality, producing mono sound and lacking the capability to create a stereo effect. Volume quality: Single speakers can only provide a limited sound volume, and can be easily obstructed by the hands, resulting in an average external audio experience. Dual speakers When talking about dual speakers on mobile phones, it is equipped with two independent speakers, which are typically located at the top and bottom of the device, allowing for left and right channel separation. Features: Stereo effect: Dual-speakers enabled mobile devices create a stimulated surround sound experience, enhancing immersion while watching movies or during gameplay. Louder volume: Both speakers produce sound simultaneously, making it less likely to be obstructed by the hands. Improved sound quality: The dual speaker setup provides fuller bass and clearer treble, resulting in a richer audio experience.

Why Am I Unable to Install Third-Party Apps on OPPO Phone
Applicable products:SmartphonesSystem version:No system version involved
Many smartphone users experience issues when attempting to download third-party apps from unknown sources. This restriction is a security measure to prevent installing harmful software on your device. However, other factors, such as incorrect settings, insufficient storage space and others, can also contribute to the problem. Being aware of these factors can help you explore alternative methods for downloading apps. Note: Check your phone's ColorOS version in [Settings] > [About Phone] / [About Device]. What Causes Third-Party App Installation Problems Insufficient storage space One reason that the installation of third-party apps might fail is due to low storage space, which prevents the system from having enough space to complete the installation process. It is recommended to free up some space before downloading. Go to the [My Files] app on your home screen and check the available space. Or go to the [Phone Manager] app on your home screen to clear cache/ uninstall residual data. If the storage space is insufficient, the following steps are recommended: Clean your phone Uninstall rarely used apps Delete unnecessary documents Download Channel Error For issues with downloading from non-App Market, we suggest enabling the "Install from Unknown Sources" setting. For instance, if you're downloading an app via the web browser, enabling the external installation switch allows the app to be installed from that source. To learn how to enable this, follow the steps below. For ColorOS 15 and above: Go to [Settings] > [Security & Privacy] > [More security & privacy] > [Installation sources]. For ColorOS 12 to ColorOS 14: Go to [Settings] > [Password & Security] > [System security]. Under APP INSTALLATION, tap [Installation sources] and toggle to enable an app you wish to install a third-party app, and a prompt will appear; then tap [Allow]. Download from the App Market: If you are downloading from the App Market and it indicates that an app is unsupported or incompatible, this suggests that there are issues with the app and it does not currently work with your device model or system. Cross-check with other devices If none of the devices can install it, it may be best to try downloading different versions from alternative channels. If other phones successfully install the app, it might indicate that it is not compatible with your phone's system. In this case, reaching out to the OPPO Support Team for assistance is recommended. * Pictures, settings, and paths might differ from those of your phones, but these won't affect the description in this article.
