Why does the screen flash when I check the text message?

Classification: Electronic Digital; Other digital products

Problem description:

Recently, it was found that the screen will flash for a while when viewing short messages, that is, it will flash when pressing "Information-View Information", and then it will not flash; And when writing information, it will flash for a while. Sometimes when you flash, you can't see the words, only the screen is left, which will be displayed later. What's going on here? Is it the LCD screen or something else? Is it necessary to repair it? The mobile phone is old. It has been used for almost five years, but it has special significance. Hehe, I am a little reluctant to change it. Please give some advice from knowledgeable friends, thank you.

Analysis:

The problem with the display screen. 30 yuan changed the line! But five years is long enough for a mobile phone. It's time to retire! Hmm. How interesting
