Introduction
The OPPO A72 is a mid-range smartphone that has gained popularity for its balanced performance, good battery life, and attractive design. However, like many smartphones, it’s not immune to issues that can affect usability. One of the most critical problems a smartphone user can face is the touch screen not working properly. This issue can render the device almost unusable, as the touch screen is the primary interface through which users interact with their phones.
In this review, we will explore the common reasons why the touch screen on an OPPO A72 might stop working, the potential fixes, preventive measures, and whether this issue is indicative of a broader problem with the OPPO A72’s design or build quality.
1. Common Causes of Touch Screen Issues on OPPO A72
1.1. Software Glitches
One of the most common reasons for touch screen issues is software glitches. These can occur after a system update, app installation, or even due to accumulated system cache. A software glitch can cause the touch screen to become unresponsive or intermittently fail to register touches.
- Firmware Update Problems: Sometimes, a new update might have bugs that affect the touch screen’s responsiveness. This can lead to delays, lag, or complete non-responsiveness in certain areas of the screen.
- App Conflicts: Certain apps, especially those that interact with the screen (such as screen recording apps or overlay apps), can cause conflicts that disrupt the normal functioning of the touch screen.
- System Overload: If the device is running too many apps or processes at once, it can slow down the system, making the touch screen appear unresponsive.
1.2. Hardware Issues
Hardware issues can also lead to touch screen problems. These issues might be due to physical damage or internal component failure.
- Physical Damage: Dropping the phone or applying too much pressure on the screen can cause the touch panel to become unresponsive. Cracks, even small ones, can disrupt the capacitive touch functionality.
- Water Damage: Although the OPPO A72 has some level of splash resistance, exposure to water or moisture can cause the touch screen to malfunction. Water can interfere with the electrical signals that make the touch screen work.
- Manufacturing Defects: In some cases, there may be a defect in the manufacturing of the touch screen itself. This could be due to poor quality control or a bad batch of components.
1.3. Environmental Factors
Environmental factors such as extreme temperatures or humidity can also impact the functionality of the touch screen.
- Temperature Extremes: Using the device in extremely hot or cold environments can affect the touch screen’s responsiveness. The screen may become slow to respond or entirely unresponsive until it returns to a more moderate temperature.
- Static Electricity: A buildup of static electricity can also interfere with the touch screen’s capacitive sensors, causing temporary unresponsiveness.
2. Troubleshooting and Fixes
2.1. Rebooting the Device
The simplest and often most effective solution to a touch screen problem is to reboot the device. This can clear out temporary glitches and refresh the system.
- Soft Reset: Press and hold the power button until the restart option appears. Select restart and wait for the device to reboot.
- Forced Reboot: If the screen is entirely unresponsive, you may need to perform a forced reboot by holding down the power button and the volume up button simultaneously until the OPPO logo appears.
2.2. Updating or Rolling Back Software
If the touch screen issue started after a software update, it might be necessary to either update to a newer version if available or roll back to the previous version if possible.
- Checking for Updates: Go to Settings > Software Update to check if a newer version is available that might fix the touch screen issue.
- Rolling Back: If a recent update caused the problem, and there’s no fix available, you might consider rolling back to an earlier firmware version. However, this process can be complicated and may void warranties if not done correctly.
2.3. Clearing System Cache
Clearing the system cache can help resolve issues caused by corrupt or overloaded cache data.
- Wipe Cache Partition: This can be done through the recovery mode. Power off the device, then press and hold the power button and volume down button simultaneously to enter recovery mode. From there, select “Wipe Cache Partition” using the volume buttons to navigate and the power button to confirm.
2.4. Safe Mode
Booting the device into Safe Mode disables all third-party apps and can help identify if an app is causing the touch screen to malfunction.
- Entering Safe Mode: Press and hold the power button until the power off option appears. Then, press and hold the “Power Off” option until a prompt appears to reboot into Safe Mode. If the touch screen works in Safe Mode, a third-party app is likely the cause.
2.5. Factory Reset
If all else fails, a factory reset can restore the device to its original settings, potentially resolving any software-related touch screen issues.
- Performing a Factory Reset: Go to Settings > Additional Settings > Backup and Reset > Factory Data Reset. Remember to back up your data before performing a factory reset, as this process will erase all data on the device.
2.6. Checking for Physical Damage
Inspect the device for any signs of physical damage, such as cracks or dents. If the screen is visibly damaged, it might need to be replaced.
- Screen Replacement: If the touch screen is physically damaged, a replacement is likely the only solution. This should be done by a professional to avoid further damage to the device.
3. Preventive Measures
Preventing touch screen issues on the OPPO A72 is largely about taking care of the device and being mindful of the conditions in which it is used.
3.1. Using a Screen Protector
A high-quality screen protector can help prevent scratches and minor damage that might affect the touch screen’s responsiveness. Tempered glass protectors are particularly effective as they offer additional protection without significantly affecting touch sensitivity.
3.2. Avoiding Extreme Conditions
Keep the OPPO A72 away from extreme temperatures, both hot and cold, as well as high humidity. Avoid leaving the device in direct sunlight for extended periods, as this can cause the screen to overheat and become unresponsive.
3.3. Regular Maintenance
Regularly clean the screen with a microfiber cloth to remove dirt, oils, and other residues that might affect touch sensitivity. Also, periodically clear the cache and unnecessary apps to keep the system running smoothly.
4. User Experiences and Feedback
4.1. Common Complaints
User feedback on forums and social media indicates that touch screen issues with the OPPO A72 are not widespread but do occur. The most common complaints involve temporary unresponsiveness after software updates and touch sensitivity issues in colder environments.
4.2. Positive Feedback
Despite these issues, many users report positive experiences with the OPPO A72’s touch screen, praising its responsiveness and clarity. The device is generally well-regarded for its performance in everyday tasks, and the touch screen plays a significant role in this positive user experience.
4.3. Service and Support
OPPO’s customer support generally receives good reviews for handling touch screen issues, with most users reporting satisfactory resolutions, whether through software fixes or hardware repairs.
5. Is the OPPO A72 Touch Screen Issue a Deal-Breaker?
While touch screen issues can be frustrating, they do not seem to be a widespread problem with the OPPO A72. Most issues can be resolved with basic troubleshooting, and severe problems are often linked to physical damage or specific environmental factors.
For potential buyers, the key takeaway is that while touch screen issues can occur, they are not common enough to be considered a significant flaw of the OPPO A72. With proper care and maintenance, the device’s touch screen should provide reliable performance.
6. Conclusion
