Questions about Lenovo A278T Skip Screen

Dear Lenovo users, hello!

The main reasons for screen hopping are as follows:

1. Static electricity Since the capacitive screen relies on the electric field for positioning, very slight static electricity will lead to the occurrence of "drift" phenomenon. If an electrostatic discharge occurs, it may even damage the capacitive screen permanently.

2. Magnetic field. The magnetic field generates an electric field, so the capacitive screen will "drift" when it is in a strong magnetic field. If the magnetic field is too strong or it is in a strong magnetic field for a long time, it may even permanently damage the capacitive screen.

3. Conductive substances, which are also the main reasons.

Conductive materials attached to the screen, such as oil, sweat, water vapor, etc., will cause the phenomenon of "drift", and if accidentally flow into the screen, it may even permanently damage the capacitive screen and other parts.

4. Ambient temperature and humidity.

The best working temperature of the capacitive screen is 5 35, the working humidity is 30% 90% non-condensing, and there may be a "drift" phenomenon when the working environment is not met. The storage temperature of the capacitive screen is -20 60, and the storage and transportation in a high or low temperature environment may also damage the capacitive screen.

Special attention should be paid to the fact that the capacitive screen is more afraid of high temperatures, and it may permanently damage the capacitive screen if it is exposed to sunlight for a long time or placed in a high-temperature environment for a long time. After the screen heats up due to charging, wait for the screen temperature to decrease before using it.

5. Voltage. When the battery voltage is low or the voltage is unstable, it may cause the capacitive screen to "drift". Using a good battery and charging your phone in a timely manner can avoid drift caused by voltage issues.

6. Physical damage.

Impact and vibration can damage the silica glass protective layer and/or ITO, causing permanent damage to the capacitive screen, leading to "drift" or even the complete scrapping of the capacitive screen. Therefore, during storage and transportation, it is necessary to avoid large vibrations and collisions as much as possible; Eliminate vigorous knocking when in use, so as to protect the capacitive screen and prolong the service life.

By avoiding the above situations, you can greatly reduce the probability of screen "drift"!

You can go to your local Lenovo mobile phone after-sales service for testing, and you can inquire through the following link.

We apologize for any inconvenience caused.

Judging from your description, you will have the problem of touch screen failure when you use A278T mobile phone, we recommend that you go to your local Lenovo after-sales site for engineers to help detect and solve it. The engineer will upgrade your phone to the latest system firmware version, and will improve the 3 conductive foams on the front shell of the touch screen.

a.Screen skipping glitches in some areas of the touch screen:

1.It is recommended to wipe and clean the screen first, and please avoid stains such as sweat stains on your hands to eliminate external interference.

2.Check whether it appears in the interface of individual third-party software, if so, it may be caused by software abnormality or compatibility, it is recommended to uninstall and reinstall or replace other types of software;

3.If the above operation is invalid, the failure of the touch screen itself is more likely, it is recommended to send it to the repair site in time to deal with it, and you can back up the body data before sending it for repair, try to restore the factory setting operation to see if it can be improved.

b.Screen skipping failure in all areas of the touch screen:

1.It is recommended to wipe and clean the screen first, and please avoid stains such as sweat stains on your hands to eliminate external interference.

2.If the mobile phone has been filmed, it is recommended to remove the film for attempt, and it cannot be ruled out that it is caused by the quality of the film;

3.Check whether it appears in the interface of individual third-party software, if so, it may be caused by software abnormality or compatibility, it is recommended to uninstall and reinstall or replace other types of software;

4.If the above operation does not work, the backup data will try to restore the factory settings.

5.If the problem still cannot be effectively solved, it may be caused by the failure of the underlying driver of the system or the touch screen itself, it is recommended to take the time to go to a nearby Lenovo authorized maintenance station for specific detection and treatment.

In this case, the first thing to check is whether it is caused by environmental problems, such as excessive heat or too humidity, and try it in a normal environment. In addition, it depends on whether it is only like this when charging, because the capacitive screen is afraid of electromagnetic interference, and it is easy to interfere when charging, so it is recommended not to use the mobile phone when charging, and just turn off the screen to charge. If it's like this when it's not charging, it's an abnormality in the phone, restart it to see if it can be solved, if it doesn't work, it is recommended that you go to the repair station to test it, and see if the brush machine can rewrite the touch screen driver If not, it won't rule out that it's a hardware failure, and the touch screen may have to be repaired or even replaced.
