iPad general touch screen failure treatment:
First, hardware damage
physical damage
The touch screen and buttons of the mobile phone all fail (sometimes suddenly normal for a while all fail) [It may be that some parts of the touch screen are loose or damaged, and need to be sent to the doctor for reinforcement and welding, or to replace the screen or components]
The touch screen of the phone is out of order, and the button is normal [the touch screen is loose and damaged, and needs to be sent to the doctor for repair or replacement] (Normal software and cpu are also bad but rare)
The touch screen of the mobile phone is biased, which can be corrected, but it is still biased after correction. [When restoring the factory or the grid chip (the last 1m) is corrected, the touch screen is intentionally biased.]
When the phone is turned on, the correction screen can be calibrated, but it cannot be calibrated all the time. [Need to replace the touch screen grid]
Mobile phone touch failure disassembly is normal. The installation fails again [the four sides of the touch screen are too tight, remove the seal strip and the touch screen lead root is broken and virtual connection]
Other hardware damage or impact:

2. Systemic damage
Crash or fake crash, this problem can be solved after closing the screen or restarting the phone;
System file damage, more due to root over the mobile phone can change and delete system files, [solution is, brush machine, again! Vicious circle ah, we carefully delete system files.]
Firmware upgrade failure, due to the network or other problems in the upgrade caused by interruption, etc., the system was damaged, resulting in the touch class file cannot be called [brush solution]

For the win8 system tablet may appear the touch screen bios systematic loading, after sleep or temporary black screen, easy to lead to frequent screen shutdown, resulting in preloaded touch program failure [this problem is difficult to solve, once it occurs, it can not be debuggable through the system software, only by entering the bios to automatically load the screen start and so on]

The ipad2 case can be cleaned, but it depends on what material it is made of, and it should be cleaned according to the material.
It is recommended to apply a scrub film, no fingerprints, eye protection, scratch, and no bubbles. And the price is more suitable, generally can be used as a gift directly to the business.
A high-quality film is very important, it is recommended to buy about 100 pieces of film, this price is the most cost-effective film.
I bought Hong Kong HOCO frosted film, feel very good, the quality is also very good.
1. Get an eye wipe to clean your iPhone's screen.

2. Some female friends like to use the touch screen immediately after applying hand cream or when their hands are wet, which may also lead to screen failure.

3. If you bought a plastic wrap or film that is very rubbish, remove it.

4. If there is no response, we can press the \"sleep\/Wake\" button on the top of the ipad for a few seconds until the program exits.

5. If the operation does not work, shut down the device and turn it on again. Press and hold the Sleep\/Wake button on the top of the device for a few seconds until a red slider appears, then slide this slider. Then press and hold the Sleep\/Wake button until the apple logo appears.

6. If the above problems are eliminated, it is certain that the hardware is broken, and we can send it for repair.
The reason why the iPad touch screen fails is that the thickness of the tempered film is too thick and the tempered film is aging, so the tempered film needs to be replaced in time to be able to be used normally
