What should I do if there is dust inside the screen? Declarations are not bad pixels

1. Close your eyes to the screen to see carefully. If the black dot is a small square dot, then there is a high probability of a dead pixel on the screen. If the shape is not very regular, it is dust. Because dust is usually dotted or fiber, it is unlikely to be square.

2. Turn off the device and look at the screen from the side. If there is a bump in the film in some places, it must be dust.

3. If the first two methods can't help you judge whether it is dust, then you can only open the film to see.

You can try this method to ensure that you can restore the peeled film

1. First of all, prepare two small strips of scotch tape.

2. Choose a room with as little dust as possible and carefully wipe the edges of the screen clean, no.

Be dusty. It can be wiped with a damp cloth.

3. Select the corner closest to the suspected dead pixel. Take out a piece of tape, put half of it on the film, and slowly lift the other half up until that point. At this point, it is easy to tell if it is dust.

Finish. If it is indeed dust, you can refer to the following methods to remove it:

4. Uncover another piece of tape and carefully stick it on the side where the screen film originally touched the screen.

point, and then uncover. If it's dust, it's going to be disposed of.

5. Carefully restore the membrane gently. If dust accidentally gets into the operation, press it.

One way can be easily disposed of. Tried and tested

May your luck be good friends, not a bad screen

In the place where the computer is maintained, you can ask someone to open the screen to clean it.

Find a professional to clean it up.

I also use the K750C, which feels pretty easy to use. However, after I removed the film to protect the screen, there was a lot of dust in the screen, and the dust particles could be clearly seen outdoors during the day (not visible at night or indoors).

There are two possibilities for a black dot to appear on the lens of the camera.

1: Maybe it's not a good thing for the dust to dry, because the dust particles are too small to make the ** shoot problematic.

2: This particle should be a black hard particle, which is more likely to stick to the outside, you can try to find it on the lens, maybe you can pick it out.

3: If you can't find it, it only means that there is something wrong with the inside of the lens, if you have a customer service near Soison, it is better, because they are more professional than the general repair of mobile phones. If there is no customer service, then you can only ask the general mobile phone repairer to do this.

In fact, I also want to remove the dust from my phone, but as soon as I thought about opening the phone, I didn't do it again, I wanted to keep the original appearance of the phone, for fear that there would be some defects that I didn't want to see after opening. Make your own decision!

Good luck!!

Put the phone on a black screen and observe whether it is grainy in the sun; There is no problem with exposure to sunlight for a short period of time, as long as the temperature is not too high.

That's caused by the phone screen is not tightly sealed, and most mobile phones now have this phenomenon! It's normal, the phone is dusty but there is no quality problem, I think the mobile phone dealer will definitely not replace it! Workaround:

1.Open the slider and open the front cover from behind the top of the slider. Start from the gap above the sign, insert your nails into the gaps above (if you don't have long nails, wait for the nails to be longer and then dismantle it), and then pry along the gaps to both sides, the action should be slow, (it's okay to be fast, don't blame me if it's broken), this is the most critical process, it may be a little difficult, but how can you see a rainbow without experiencing wind and rain!

Only by going through hardships can we become an opportunity within a machine!

2.After the front cover is removed, you can see our inner screen, remember to be extra cautious when wiping the screen, it is best to wipe it with the glasses cloth that wipes the glasses, and do not use paper supplies, because there are many burrs on the paper, which will wipe the screen.

3.The dust on the surface has been cleaned up, but what we want is to keep the screen completely away from dust, I believe you are here, you have seen that there is a sponge cushion inside the front shell, I believe this is used to prevent dust, but the effect is really not flattering. Let's perfect this feature for Arnold.

4.Tools: a roll of double-sided tape, a sharp knife (don't use a kitchen knife), a discarded CD, a ruler.

5.Tear a piece of double-sided tape and stick it to the disc, don't stick it too tightly, use a ruler and a knife to cut the double-sided tape into long strips with a width of 2mm, and then remove it from the disc, remember to remove the glue! (You may not be able to remove it), and then glue it around the sponge pad of the inner cover.

You have to be very careful with this process, because if it sticks, it may stick to the mat and you will be hopeless (of course you can get a new one). Each side of the surrounding should be glued, after actual testing, it is best to stick two layers of double-sided tape on each side, which will be tighter.

6.After the above process is done, it is relatively simple post-work, wipe the inner screen of the shell clean, and it's OK.

7.When installing the front cover, start from the bottom of the mobile phone, use the bottom of the front cover to jam the bottom of the slide cover, there are two small card slots under the shell, remember to see clearly, don't install it from above, install the bottom, press down the top of the shell, and you're done.

Hope it helps!

The fact that there is dust on the screen of the phone is due to the fact that the phone is not completely sealed, there are many voids, and dust will enter.

Solution: You can go to the mobile phone store to disassemble and clean the ash, but if there is not much dust, it is not necessary, and you can't disassemble the phone by yourself, which is risky. Accessories such as dust plugs can be used at ordinary times, and more attention should be paid not to put them in dusty places.

When the mobile phone screen leaves the factory, it is necessary to go through a strict performance test, the shrapnel microneedle module as a connection test module, can play a good conduction role, the performance test is stable and reliable, can transmit a large current of 50A, circulate in the same material, the current is stable and reliable!
