The screen of our mobile is everything. If something goes wrong, the whole experience may be affected. If you don’t turn it on, it gets worse, since we can’t do absolutely anything. Any mobile is susceptible to problems with its screen , including those of Huawei . We will therefore take a look at the solutions that we ourselves can put in place to try to make our screen work normally.
On many occasions, failures on the screen are usually indicative of a hardware failure. In that case, we will need the help of the Technical Service to solve the problem. However, there are several diagnostic tests and solutions that we can carry out before thinking about major causes.
If the screen goes bad
Phantom touches or performance issues with the touchscreen are typically the most common touchscreen issues. To try to find the error we must do a series of checks, which in a large part of the cases solves the problem.
Restart the mobile
It is the first step. Whether due to an app or because the touch sensor may have been temporarily corrupted, restarting the mobile will make the problem solve on many occasions . If the problem persists we should start to think that some app may be causing the problem
Safe Mode
In this case, many downloaded apps can cause screen problems. To find the faulty software we will have to restart the mobile in Safe Mode. In this way we will prevent said app from loading in the system and generating the error. To enter this mode we must hold down the power button for a few seconds and release when we see the Huawei logo appear. Then we press and hold down the volume down key and hold it down until the terminal completely restarts.
Once restarted in “Safe Mode” we will have to uninstall the installed applications in order from newest to oldest and check if the problem on the screen disappears.
Test the screen
To see if there may be a hardware problem, there is an infallible method that Google itself recommends and that works on Huawei mobiles. The first is done by dragging a desktop icon diagonally to all corners of the screen and slowly. In this way, if dragging is interrupted at any point, we can identify the part of the screen that could be damaged. We must do the same by dragging the notification bar to the bottom.
Clear the cache
In many cases it is the data stored in the cache of the phone that can be corrupted and cause the error. This will cause certain problems in the terminal including problems with the screen. To clear the cache we will have to turn off the phone. Then we hold down the button to increase the volume of our mobile next to the power for a few seconds. The phone will enter Recovey Mode and with the volume up and down buttons we will move to “wipe the cache partition” and use the power key to confirm. The mobile will restart and when the system starts the problem should have disappeared.
Update the software
The first thing is to check that the terminal has the latest software version available for the system. This is the first step we should always take before looking for other solutions. Many users have fixed the display issue as Huawei always introduces patches that fix compatibility issues and malfunctions throughout the history of their devices.
Secret menu
In order to test the touch screen, there is a secret code that will perform tests to determine where the fault is. For this we will have to go to the marker of our mobile and enter the code * # * # 2664 # * # * Once the tool is done, it can also reveal us, there is a hardware problem that wants the panel to be reviewed by a technician professional.
If the screen is not visible or does not turn on
In this case we will have less room for maneuver , but we can always take a series of actions to try to solve the error. It goes without saying, that if none of these methods works, it will be necessary to make an appointment with the Huawei Technical Service to determine the origin of the failure and offer us a solution.
Forced restart
When the phone screen does not respond it has gone black, we must try to force its restart. To do this we have to press and hold the power button for 10 – 12 seconds, until we see the Huawei logo. This action performs a small power outage and forces the device to restart. Remember that forcing the reboot will not delete any content on the phone except that which is damaged or invalid.
Check load
Another solution will make us go to the plug and connect the charger to see if there is any reaction . In many cases, a damaged battery can cause the screen to perform erratically. When a user has a high battery percentage and the black screen is found shortly after, it is normal to rule out a battery problem and focus on the screen. Putting the mobile to charge will get us out of doubt.
A hit
Although the terminal does not have any scratches, a recent blow or drop may have caused internal damage that affects the normal operation of the screen. In this case, we only have to contact Huawei technical service to find the problem and offer us a solution. In order to verify that the screen is not working, we can always make a call to the device. If it sounds but nothing is seen and we have tried all of the above, the problem is undoubtedly in the touch panel, which may have been disconnected.
