Performance Issues Following Android 4.2 Update
An upgrade to Android 4.2 resulted in significantly reduced performance on a Nexus 7 device. Users experienced noticeable delays when launching applications, navigating the home screens, and loading websites.
The cause of this slowdown remains uncertain. Speculation indicates that rooting the device may have contributed to the issue. However, a straightforward solution was discovered.
A factory reset restored the Nexus 7 to its original condition, effectively resolving the performance degradation. This fix was successful even after the device was rooted and the same applications were reinstalled.
How to Perform a Factory Reset
To initiate a factory reset, access the device’s Settings menu. Then, select the “Backup & reset” option. Finally, tap on “Factory data reset” to begin the process.
This will erase all data on the device, returning it to its out-of-the-box state. It is recommended to back up important data before proceeding with a factory reset.
Nexus 7 Touchscreen Issues and Solutions
A common issue reported with the Nexus 7 involved intermittent touchscreen responsiveness. Users experienced instances where the device failed to register touch input, particularly during actions like scrolling through webpages.
Despite not being a complete failure, the touchscreen would often recognize only the initial portion of a swipe gesture, failing to complete the action.
Identifying the Root Cause
Investigations revealed that the Google Currents application, pre-installed on the device, was the primary culprit. Automatic background synchronization within Currents was consuming system resources and interfering with touchscreen functionality.
To resolve this, users needed to access the Currents app settings and disable background syncing.
- Open the Google Currents application.
- Tap the menu icon.
- Select Settings from the menu.
- Uncheck the Enable background sync option.
Disabling this feature prevents the app from continuously updating in the background, freeing up resources for optimal touchscreen performance.
Beyond Currents, it’s important to monitor other applications for excessive background data synchronization. Constant syncing by multiple apps can contribute to overall performance degradation.
Therefore, regularly reviewing app settings and limiting background activity is crucial for maintaining a responsive and smooth user experience on the Nexus 7.
Nexus 7 Power and Charging Issues
Should your Nexus 7 exhibit a complete freeze, failing to power on or accept a charge, a common initial step would be battery removal and reinsertion. However, it’s important to note that the Nexus 7’s battery is not designed to be user-accessible.
Given the lack of user-serviceable battery access, an effective troubleshooting method involves a prolonged power button press. Hold the power button continuously for a full 30 seconds. While you may have attempted this previously, a complete 30-second hold is often necessary to initiate a reset.
This technique has proven successful in resolving instances where a Nexus 7 refuses to respond to power or charging attempts.
A sustained press can often resolve underlying software glitches preventing operation.
Consider this a hard reset procedure for the device.
Addressing Screen Delamination on the Nexus 7
The occurrence of screen separation, while hopefully less frequent in newer models due to improved quality assurance, was observed in some Nexus 7 devices. A simple diagnostic test can determine if your device is affected.
Gently press the upper-left corner of the screen. A noticeable sponginess accompanied by a creaking sound indicates that the screen is becoming detached from the device chassis; it should feel firm and solid.
Attempting a self-repair could potentially invalidate your device’s warranty. If you encounter this issue, contacting Google for a replacement is advisable.
However, a successful repair can often be performed independently. Numerous proposed solutions are available online. Our testing revealed that the most effective method involves the creation and installation of custom washers.
These washers prevent the internal screws from being over-tightened, which can contribute to pressure on the screen. It’s possible that the original screws supplied by Asus were marginally too long.
A detailed, photographic guide to this process is available on XDA Developers. This resource provides a comprehensive walkthrough of the repair procedure.
Removing the Nexus 7’s rear cover is relatively straightforward. A guitar pick or a sufficiently strong fingernail can be utilized to carefully pry it open.
Screen Flicker on Nexus 7
A flickering screen can sometimes occur on the Nexus 7, particularly when the ambient light is dim. This issue is often most apparent when viewing content with a predominantly white background.
For instance, a flicker might be observed at a brightness level of 10% while browsing to Google.com. Observations suggest a possible correlation with Wi-Fi connectivity; some users have noted increased flickering with a less robust wireless signal.
Should you encounter this screen flicker, several potential solutions are available. Increasing the display brightness and deactivating automatic brightness adjustment is one approach, though this may lead to reduced battery performance in darker environments.
Many users have also found success by disabling Wi-Fi optimization. To implement this, navigate to the Settings application, select Wi-Fi, access the menu, choose Advanced, and then deselect the Wi-Fi optimization feature.
It's important to note that disabling Wi-Fi optimization can also affect battery life.
Troubleshooting Steps
- Increase display brightness.
- Disable auto-brightness.
- Disable Wi-Fi optimization (Settings > Wi-Fi > Menu > Advanced > Uncheck Wi-Fi optimization).
Consider the impact on battery life when implementing these workarounds.
Color Distortion on Nexus 7 After Video Playback
The Nexus 7 incorporates “NVIDIA PRISM Display Technology” designed to optimize power consumption during video viewing. This is achieved by dynamically adjusting the backlight intensity and enhancing contrast and color vibrancy. However, a potential issue can arise following video playback.
Users may observe that the screen continues to display colors with an over-saturated or “washed out” appearance even after the video has concluded. While NVIDIA PRISM is intended to revert to standard color settings automatically, this doesn't consistently occur.
A quick, temporary solution involves briefly turning the display off by pressing the power button, then reactivating it. This action typically restores normal color representation until the next video is played.
Permanent Resolution Options
For a lasting fix, consider disabling NVIDIA PRISM. It’s important to note that disabling this feature will likely reduce battery life when watching videos.
Implementing this requires root access to the device. Detailed instructions for disabling PRISM, utilizing command-line operations or scripts, are available on the XDA Developers forum.
Alternatively, a paid application, the NVidia Tegra PRISM Toggle, can be found on Google Play, offering a user-friendly interface for managing this setting.
- Disabling PRISM will impact battery performance.
- Root access is necessary for manual adjustments.
- A dedicated app provides a convenient toggle option.
