The mobile phone was bought by Nokia's Lumina 525 for 14 years. Last week, Dad said that the screen was not bright, and the power button was broken. Because this phone supports double-click to wake up the screen, a 'lock screen' from the app store was issued. Will use it. Today, I took the time to work on my own to get a repair. The following picture shows:
Open the back cover
Remove the battery
It is worth noting that the screws are six-flowers. The length of the screws is different. Be sure to remember the position or the top of the screen will be bad.
After removing the screws, the only thing left is the buckle. Just pull the crowbar from the corner.
The place marked in the figure above is that the display and the touch screen can be removed after the cable is buckled.
The chip shield is welded off. . . . Can not see the interior. . . .
Soldering Iron Outbound
The big solder joint on the icon is where the welding has been welded. 
Add gaskets to avoid loosening
This is the screen on the back of the screen and the touch screen is separated, so it can be used to save money. . . Although not a few dollars. . .
Install the battery
Light up
Although this mobile phone system has been abandoned by Microsoft, but the software is also commonly used qq WeChat is also good when the backup machine is enough battery, then the normal use of 2-3 days a charge this phone is real leather
