Introduction
The OPPO A72 is a classy mid-ranger that has enjoyed immense popularity for its balanced performance, good battery life, and stylish looks. Unfortunately, just like with any phone, problems can arise, which then affect its usability. However, a very critical issue for any smartphone user is the non-working touch screen. This problem almost renders unusable any device, as there is nowhere else for the user to interface with the phone except through his fingers.
In this review, we discuss common causes for the OPPO A72’s touch screen ceasing to work, what can be done about it, prevention, and whether this issue is something pointing to a general design or build quality problem with the OPPO A72.
1. Common Causes of Touch Screen Issue on OPPO A72
1.1. Software Glitches
Likely the most common issue for the unresponsive touch screens are software glitches. They can come about after system updates, app installations, or even just through the accumulation of system cache. A software glitch will make the touch screen fail completely or partially stop registering touches.
Firmware Update Issues: Every now and then, a new update might present some bugs that trouble the touch screen response. This can cause a delay, some degree of lag, or something being completely unresponsive in certain parts of the screen.
App Conflicts: Some applications, especially those that anyway interact with the screen (such as screen recording apps like AZ Screen Recorder or overlay apps like Twilight or Lux), can cause conflicts with normal touch-screen functioning.
System Overload: Too many apps or processes running simultaneously can bog down the system, thereby making the touch screen appear unresponsive.
1.2. Hardware Problems
Hardware problems are another set of issues that can cause the touch screen to malfunction. These issues are usually caused by physical damage or failure of the internal components.
Physical Damage: Dropping the phone or applying pressure on the screen can cause the touch panel to stop responding. Cracks, even very tiny ones, can wreak havoc on a capacitive touch function.
Water Damage: The OPPO A72 has some amount of splash resistance; however, the touch screen may malfunction if it is exposed to water or moisture. Water messes with the electrical signals responsible for making the touch screen work.
1.2 Manufacturing Defects
As a matter of fact, the touch screen could have defects coming in its manufacture. This could be due to poor quality control or of a problematic batch of components.
1.3 Environmental Factors
Environmentals, including temperature extremes or moisture, can also determine the functioning capacity of the touch screen.
Temperature Extremes: When the device is used under very hot or very cold conditions, the responsiveness of the touch screen gets affected. It gets slow to respond or does not respond at all until it becomes more moderate in temperature.
Static: A buildup of static electricity can interfere with the capacitive sensors of the touch screen, causing temporary unresponsiveness.
2. Troubleshooting and Fixes
2.1. Rebooting the Device
Considered the simplest and most effective way to fix a touch screen problem, rebooting clears temporary glitches and refreshes the system.
Soft Reset: Hold the power button until the restart option appears. Select restart and wait for the device to reboot.
Forced Reboot: When the screen is unresponsive, one may try forced reboot by holding the power button and the volume up button simultaneously until the OPPO logo shows.
2.2. Update and Roll Back Software
If the touch screen problem began subsequent to software updates, you might have to update further if possible or else roll back to the prior one available.
Checking for Updates: Settings > Software Update should be navigated on your device to check if a newer version that can fix the touch screen issue is available.
Rolling Back: When the problem is created by a recent update and no fix is available, one may want to roll back to the previous release. If you don’t go about this in the right way, you could end up voiding your warranty.
2.3. Clearing System Cache
If corrupt or overloaded caches are causing trouble, clearing the system cache can help.
Wipe Cache Partition: This can be done in Recovery mode. First, shut down the device. Then, press and hold both the power button and the volume down button to enter Recovery Mode. From there, select the option “Wipe Cache Partition” using the volume keys to navigate and the power key to confirm.
2.4. Safe Mode
This will disable third-party apps and thus help you confirm whether the touch screen is malfunctioning due to one of them.
How to Enter Safe Mode: Press and hold the power button until the power off options appear. Then press and hold “Power Off” until a prompt pops up to confirm rebooting into Safe Mode. If the touch screen works in Safe Mode, then a third-party app is the likely culprit.
2.5. Factory Reset
If everything appears to be in place and yet there is a touch screen issue, then give a factory reset try to put it back to its default setting.
How to Do a Factory Reset: Head over to Settings -> Additional Settings -> Backup and Reset -> Factory Data Reset, then tap on Factory Reset Device. Remember that you should have backed up on your data because this is going to wipe everything from your device.
2.6. Inspection of Physical Damage
Inspect the device to check for any physical damage such as cracks or dents. If anything can be seen visibly damaged, it may be the replacement.
Screen Replacement: The solution in case the touchscreen is definitely damaged is to replace it. It should be done by a professional so as not to cause greater damage to the device.
3. Preventive Measures
In preventing any issues with the OPPO A72 touch screen, much will depend on minding the device and the conditions under which it is used.
3.1. Using a Screen Protector
A good screen protector may prevent superficial scratches and minor damages that could very well compromise the responsiveness of the touch screen. Tempered glass protectors shine simply because they hold the protective qualities with lesser measures of compromise on the touch.
3.2. Avoiding Extreme Conditions
The OPPO A72 should be kept away from extremes of temperature–particularly heat and cold–and atmospheric variables like heavy humidity. Also, it’s imperative not to expose the device to direct sunlight for a long period of time because the screen might heat up and lose its responsiveness.
3.3. Maintenance
Clean the surface with a microfiber cloth as part of a regular schedule, removing dirt, oils, and other residues that reduce touch sensitivity. Periodically empty the cache as well, deleting apps if necessary so that your system will remain faster.
4. User Experiences and Feedback
4.1. Common Complaints
What is heard from users via forums and social media is that touch screen issues do occur, though not widely, with the OPPO A72. The usual complaints range from temporary unresponsiveness after software upgrades to touch sensitivity problems in cold weather.
4.2. Positive Feedback
Some users say they have had good experiences with the OPPO A72’s touch screen, hailing its responsiveness and clarity. The device is generally considered to be fairly good at everyday use, and the touch screen makes a big impression in such user feedback.
4.3. Service and Support
The touch screen issues are reportedly addressed with customer support through the OPPO company, with software fixes or hardware repairs providing a satisfactory answer to most users’ concerns.
5. Is the OPPO A72 Touch Screen Issue an Absolute Deal-Breaker?
Touch screen issues can be frustrating, but they don’t seem widespread with the OPPO A72. Most are easily handled by simple troubleshooting, and those that present a greater problem are usually brought about by physical damage or specific environmental impacts.
A takeaway for a potential buyer would be that issues with the touch screen can happen but are not frequent enough to be considered a serious drawback of the OPPO A72. With due care and maintenance, the touch screen of the device should serve well.
