Matters needing attention in mobile phone maintenance

Don't be cheap when repairing mobile phones.

Nowadays, mobile phones rarely fail in normal use, and they are basically damaged or flooded by themselves. If you go to the official after-sales repair shop for repair, there is no warranty. If you want to repair your mobile phone, you must ask more questions and then choose the one with the best price. Never choose the cheapest one. The cheapest may be the worst quality parts on the market.

How to find a reliable mobile phone repair shop

Mobile phone maintenance masters in the industry generally only do mobile phone maintenance, and others do not. Mobile phone repair shops may be relatively small and generally decorated. The maintenance master's desk may be messy, but it is fully equipped and filled with mobile phone motherboards or maintenance tools.

This kind of expert is usually very professional. For example, some mobile phone repair masters are located in Huaqiang North, Shenzhen. They usually only do mobile phone maintenance all day long, do nothing else, and have no time to go to your home to repair your mobile phone.

Will accessories be stolen from mobile phone maintenance?

Nowadays, mobile phone accessories are basically encrypted, such as batteries, motherboards and cameras. If the accessories are replaced, there may be a prompt when they are not opened or opened. For example, Apple's mobile phone, the official has encrypted the screen, motherboard, battery, camera and other accessories. If you replace these accessories, there will be a pop-up prompt when you start the machine.

Other domestic mobile phones are generally the most expensive, such as motherboards and screens. The mainboard except the screen and other accessories are basically tens of dollars. I believe no business will steal your accessories for these tens of dollars.
