Other people's mobile phones, mi11, are new, but have been phased out by their owners because of the failure of the switch button (power button) and failure to eject it, which is equivalent to the fact that the button was always pressed, so the cell phone was activated, repeatedly on the page, but not at all (sometimes it was activated, but it was automatically re-opened shortly thereafter, and then, as mentioned above, could not be activated)。
The owner said it was sold to the factory, but it was not fixed. The owner had to get rid of the phone and buy a new one。
It's a shame if it's working or working. The owner showed interest in me and gave me this phone。
I'm starting to think it's just a power button that's broken, and it should work. So i'm going to change it to a new power key. The internet cost $20 to buy one back and the machine was ready to be replaced. It was discovered that the cell phone had not been opened at all, that is to say, there was no unopening of the cell phone since it was sold, so it could not be repaired — what was the reason? You can imagine。
New opener button
When the new buttons are replaced, the problem is not solved, the problem is the same — is the new buttons also problematic? It seems unlikely that if new purchases are problematic, the shopkeeper will have no business because the buyer can return the goods。
I suspect that the failure is not at the power button, but at the battery level, considering whether to buy a new battery. I thought again, try not to put that button in a long hole to fix it (but it's got a lined-up button on the main plate) and find that the cell phone is working properly, which proves that the malfunction is actually on that button, not on the battery: when the button is stuck in the long hole and it is fixed from inside, the user presses it, it doesn't pop out, it doesn't work。
The phone i took off
At this point, i suddenly thought of going online to see if people had any maintenance experience. As a result, there was no record of other people sharing their maintenance experience, but there were a lot of people talking about the problem, so it became clear that it was the design defect of the cell phone. - the spring components in the key are not designed to be rational, so that when the key is pressed, it does not pop properly。
You see people on the internet talking about it
That too
And this
Well, then i can't fix it。
But it's still so new. It's a shame it's abandoned. Is there any way to make it work
I thought, since the button doesn't work, would you mind not taking it? That means i'm gonna turn this off when i turn it on, and i'm gonna never use it again, and i'm gonna keep the phone on, so i don't need to use the button
But what if the screen goes out? How do you wake up without a key
I've never played a milliphone before. I'm not familiar with its functional menu. But it doesn't matter. It's the android system. It should be simple. Indeed, in the settings, the functions of " lift the bright screen " and " double-click the bright screen and the sill screen " are seen。
Cellular feature flash screen function
So i turned these two or one of them on, and then i pulled the line card off the main plate -- the switch button was still installed on the phone, but the internal line was disconnected from the main panel, so it didn't work, and the phone kept it open, and it was used to wake up the screen with the "blow up the bright screen" or "bid-light screen" feature
In fact, this cell phone power key can be filled in other ways (e. G. Suspended balls) except for the switch that cannot be replaced in other ways. In other words, power buttons are out of use, and the impact on mobile phones should not be significant。
But what if the phone goes off by accident? How do we get it back on
In the event that the cell phone is accidentally turned off, the back of the cell phone will be turned on again, the button on the key line will be pulled back to the main panel and the phone will be turned on immediately. This seems to be a bit of a problem, so it should be ensured, as far as possible, that it is not cut off. But it's not a problem for someone who can do it。
The back of the cell phone is glued up, and when it is opened, it needs to be heated with an electric blower and then pulled off with a suction. But i think that if there's a cell phone shell, like the one below, it can hold the cell phone back and hold it firmly on the phone, then it can be used without glue, but just don't take it off while it's being used。
