How about your phone touch screen?

What are you asking? I can help you analyze the problem.

Questions. It's not that I'm always playing with my phone, and I don't respond when I press it.

I'm sorry I can't send the message.

Is it because the phone is stuck or is there no response directly?

Is it stuttering or direct unresponsiveness.

Questions. It's just that after a while I got a new phone.

What does that mean?

Not quite sure what you mean.

If you are a Huawei phone, click My Huawei - Services - I want to detect - Screen to check if it is a problem with the screen.

Questions. It's just that when there is no response, after a while there is a reaction again.

That is the problem of lag caused by the small running memory of the mobile phone.

For system problems, you can open [Phone Manager], select [Junk Cleanup], and click [Clean Selected Junk] after the scan is completed.

Questions. The new phone runs on 12g RAM.

It will lead to the failure of the touch screen of the mobile phone, and the memory of the mobile phone is too small, and the conflict between the stuck software and the mobile phone is incompatible, which will lead to the failure of the mobile phone touch screen.

Questions. It shouldn't be a screen problem.,If it's a screen problem, it's always a problem.。

If you say that, it's not a screen issue.

Miscellaneous questions. Questions.

Be clear. If you have a new mobile phone, you can test these problems one by one, and if you can't find out, you can take a look at the after-sales service.

I haven't tested it now, and I don't dare to conclude that your phone is the problem.

Let the repair phone change the screen.

1. Although the current touch screen is very hard and wear-resistant, static electricity, an extremely unstable factor, can easily break through the capacitive screen. Although the surface of the capacitive screen will be added with a layer of antistatic treatment, it does not mean that it can withstand the instantaneous voltage brought by the static electricity of the human body. 2. The high temperature mobile phone screen is afraid of high temperatures, when the surface temperature of the screen reaches about 40 degrees, it may cause drift, and the capacitive screen will reduce the life of the capacitive screen if it is at this high temperature for a long time.

Therefore, in the scorching summer, try to avoid exposing the mobile phone to the outdoors when outdoors, and playing games for Android phones for a long time will also cause high temperature of the machine. If you're in the heat, the best thing to do is to let him cool. 3. Oil and sweat and other mobile phone screens are very afraid of conductive media such as oil and sweat, and their coverage on the screen will make the mobile phone screen unresponsive or screen drift, so if you find oil, sweat and other substances, you should wipe them dry as soon as possible.

4. The working principle of the voltage capacitive screen is that when the finger touches the capacitive screen, it will take away the point current on the screen, and the screen will evenly transmit the equal current from the four corners to fill the position of the paper press, and use this to do the positioning, so in the case of unstable transmission voltage, the effect of drift will appear, so try to avoid charging after the power is less than 20%, if it is lower than the best to charge immediately. And it's better to charge the mobile phone battery as you use it than to flush it when it's exhausted. 5. Put a small magnet on the screen in the magnetic field, and you can soon find that the capacitive screen has a temporary failure, which will cause permanent failure after a long time.

Therefore, try to avoid close contact between the phone and the speaker or other magnetic objects.
