The MP4 s keys seem to be a bit out of order

If you read e-books a lot, this is easy to happen when you press back. If you are not going to repair it, it is recommended that you use something like a needle to pick out the stuck button first, and then press it softer later. Also, it is better to set up automatic page turning to read e-books.

The landlord added that he had tried it with a needle, so have you picked out the button (that is, it is not in the state of pressing all the time)? If it's no longer in the state of pressing all the time (it should be possible,Before, my *** was that kind of phenomenon.,Because there is a border next to the key, it's easy to fall in.,It will be in the phenomenon of long pressing.,If the key is the power on key, it's even worse.,Even the machine can't be opened),That means the button can still be used。 As for the lack of elasticity, this is very normal, because the elasticity of the keys is due to the fact that there is a spring-like device under the key, the keys are used too much or use too much force will fail, if you can't take it to repair it in time, pay a little attention to it when you use it in the future, for example, when pressing, the force should be vertical, just don't press it to avoid being stuck again, my MP4's backward key is not elastic, but my key is more convex so it is not easy to get stuck, and it will not affect normal use.

I think the landlord is also home for the New Year, it's hard to find a place to buy to repair it, I hope it will help you.

You can also adjust the circuit board!!

Let's string it! Just take it apart and align it to estimate.

The inside of the new button is supported by a pot-shaped elastic shrapnel, sometimes if the quality of the button is very poor, it will be pressed, and it can't be bounced, if it is repaired, it will be replaced with shrapnel!! I've repaired it myself before, just take the keys apart and restore the sunken shrapnel, and that's it!! If it is within the warranty period, it is best to take it to the seller for free to repair, he will take it to the buyer to repair, it is free!!

Won't let you pay, unless it's a profiteer.

See if your model is easy to disassemble and assemble, if you can disassemble it yourself, teach you a way to repair: find a cigarette case to tear off a piece of tin foil from the top, and use double-sided tape to glue the side with tin foil outward under the button (glue tightly, otherwise it will fall down and your machine will go crazy), after assembly, the button should be able to use. I'm afraid I can't find someone who can dismantle it.

This is mainly because the conductive sheet in the button is broken, mainly because you press too many times, so that it loses its elasticity, so now you press it will not ring, I will change this thing, because I often get off the phone, every time I will keep useful things, in fact, if you want to repair, they will change the button at most, dozens of yuan on the line, remember that it is not your machine that has a problem, pay attention to the next time, you can guarantee better.

That may be a program problem, ask the seller to update the firmware. If it doesn't work, let them take it apart and fix it. If it is within the warranty period and it is not broken by yourself, the seller will never charge for it.

My own MP5 keys have been broken twice, free repair during the warranty period, give it to the dealer he has his own way about a week

Find a merchant to repair during the warranty period, and it is recommended that you give the seller a ** first.

5 yuan to repair once and change the button.

Internal problems that need to be repaired.

It is recommended that you go to a regular after-sales service to repair or upgrade the software, which should be a problem with the software.

This kind of physical key has a lifespan, if your mp4 is still very new, then you have to go to the seller to check it.

My mp4 is also now.,Look at the e-book with the time Chang Xing finger is long.,The button to turn the next page was broken by me with Sakura.。。。

This is not caused by a virus Because of touching the panel of the buttons and making Qin offset, so slip to know that there is a problem with absolute completion It's best to send it to the oppo repair point to repair it This cost is very low.

The keys are damaged. It's a bit difficult to return. A good merchant can help you with the warranty. But your situation is not necessary. The shipping cost is not necessarily guaranteed. Just go straight to the repair shop and change the buttons... Save time and money.

This is not a matter of software, it is more likely to be the cause of hardware, you find a place to repair the mobile phone and let him test the buttons for you. This kind of is generally easier to repair. It may be that there are some places with the motherboard that are not in good contact. Thanks.

Did you lock the keypad lock? You see there's a little switch on the mp4, and you can just flip it to the other side.

This,It seems that it can only be sent for repair.。。。 **It doesn't matter if you buy it, just have a maintenance point.

I'm not a master.

If you know how to use a soldering iron, you can do it yourself by just having a button replacement at hand. If you don't have both, you can't do this only by sending it for repair, and you can basically get it done if you take it to repair your phone. **It's about 10 20, and you can get it back on the same day.

You can only go to a repair shop to replace the keys.

It's not that difficult, use the disassembly shell to see where the key of the key is. Whether you want to use a screwdriver to disassemble the board inside. If you want to, it's better to fix it, then you will be afraid of breaking. Let's take a look first.

It should be that the keys are not flexible, so take them apart and change them.

Replace the buttons that are not often pressed, and change them in the place where you repair your phone.

The motherboard is broken, so if you repair it, you might as well buy a new one.

Hello I am Newman's after-sales state fuel technology, it depends on what model of the machine you are talking about, some of the machine is with touch control, if you are talking about that kind of key, it will be relatively expensive, if it is an ordinary buried button, we generally charge 20 yuan, of course, these are for over-insured machines, if your *** is within the warranty period is completely free service.

Up to 20 quick money to get it If you want more, it will be too dark.

If it's broken, change it, it's very dark.
