Mobile phone repair
The so-called "prevention is better than cure", if you wait until something happens to your mobile phone every time, it may be too late! Here are five examples of mobile phones that are easy to use and bad, all of which are common glitches. If you can do it, you can keep your phone safe.
Avoid touching the metal sheet of the SIM card. Any scratch or damage will make the SIM card unreadable.
Never put the mobile phone in the air outlet of the air conditioner, because the water vapor condensed on the mobile phone will corrode the board invisibly.
Charging time should be enough, usually 8 hours is enough. If it is overcharged, the battery life will be shortened.
Remember, if the mobile phone antenna is unnecessary, please don't pull it out or play like a toy, so as not to affect reception.
In order to prevent the mobile phone from accidentally getting wet, a waterproof bag and a waterproof capsule can play a protective role.
