1. After the mobile phone falls into the water, I believe that most users can fish out the mobile phone as soon as possible, which is also very important, reducing the time of contact between the mobile phone and water will minimize the damage to the mobile phone. The longer the phone is immersed in water, the more harmful it will be to the phone's earpiece, microphone, screen, and motherboard. What should I do if my phone gets water?
Teach you to properly handle water ingress on your phone.
Remove your phone from the water, quickly dry the water on the surface of your phone, and remember not to try to turn it on. Many users will subconsciously press the power button after taking out the mobile phone to see if the mobile phone can still be turned on, which is very wrong, even if the mobile phone itself is not damaged, once turned on, it may cause the result of burning the motherboard.
The correct way to deal with it is to quickly remove the battery after taking out the phone, regardless of whether the phone is turned on before it is dropped. Then throw a few times at the side with more openings on the phone (such as the data cable interface), or the side with a large gap, and throw out the water in the phone. Hold the phone when you throw it, otherwise if you throw it out, you can be ready to buy a new one.
There is a problem involved here,At present, a considerable number of mobile phones can't open the back shell,What to do if the battery can't be taken out,There is really no particularly good way to do this,Generally, the mobile phone will have a black screen after entering the water,For those mobile phones that can't deduct the battery,Don't try to press the boot button after the black screen,Or throw the water out first。

If the water is ingress, take it to the after-sales service to test and take a look!

3. Some mobile phones can be turned on and used normally after simple treatment, but the mobile phone is composed of precision electronic components, and there is a hidden risk after water ingress, so it is recommended not to try to turn it on.
4. During the after-sales maintenance process, data may be lost.

Take you to understand what is going on with the mobile phone screen jumping.
It is recommended that you check if your graphics card is overclocked. WOW has quite high requirements for the stability of the graphics card, and some graphics cards can run software such as 3DMark after overclocking, but in WOW, the screen will be blurred, but it will not crash (it is the broken colorful triangle you described, which keeps flashing, starting less, and more and more after a period of time). Try reducing the frequency of your graphics card. >>>More
