How to repair your phone in a pinch

Accidental damage to the phone? Don’t panic! This article provides some simple and fast emergency repair methods to allow your mobile phone to be supported by professional maintenance personnel. We will also list some "repair" methods that are circulated but are ineffective or even aggravated damage to help you stay away from the misunderstandings of mobile phone repair.

Prevention is better than treatment

Before introducing emergency repair methods, take a look at how to prevent mobile phone damage:

Choose a durable phone: When purchasing a phone, check its IP rating. IP level (international protection level) indicates the equipment's dust resistance (first digit) and water resistance (second digit). The higher the IP level, the more durable the phone is. The first digit (dust resistant) ranges from 0 (completely fragile) to 6 (completely protected); the second digit (water resistant) ranges from 0 to 9. IP4 or above can be splash-proof, IP7 or above can be soaked in about 1 meter of deep water for 30 minutes. The IP68 rating of Samsung Galaxy S9 means it can be soaked in nearly 1.5 meters of deep water for 30 minutes.

Flagship phones usually have higher IP ratings, such as the IP67 for the iPhone X and the IP68 for the Samsung Galaxy S9. Even if your phone's IP rating is not high, the phone case provides additional protection, especially those that cover the corners of the phone.

Screen Protector: Although it is thinner and cheaper than a mobile phone case, the protection range is limited, mainly against scratches, and has limited protection against falls. But for screens with slight cracks, it can play a certain protective role.

Collaborate on screen cracks

The mobile phone falls unexpectedly, and will be abraded at a minor point, or it will be crushed to pieces. First check the appearance and function of the phone.

Minor damage: If the phone is functioning properly and there is only minor damage, no repair is required. But pay attention to whether there is any liquid leakage (battery or adhesive), and if so, stop using it immediately.

Serious damage: If the crack is serious and the internal components are exposed, it should be stopped to avoid causing greater damage or battery failure. Seal the phone and the fallen parts in a plastic bag and contact the manufacturer or retailer for repair or replacement.

Screen cracks: If the phone is functioning normally, you can use adhesive screen protectors or tape to fix the cracks to prevent debris from falling off. But if there is a change in color, you need to professionally change the screen.

It is recommended to contact a professional to change the screen as soon as possible, or replace it yourself (requiring certain hands-on skills and checking relevant tutorials). The iFixit website provides detailed disassembly and repair guides for many mainstream mobile phone models.

Contact water inlet

After the mobile phone is in water, turn off the machine immediately, wipe it dry with a clean cloth or towel, and place it on a flat solid surface and air-dry it naturally. Avoid turning on or charging before air drying. If possible, remove the SIM card and memory card.

It may take 48 hours to fully air-dry. Check the IP level of your phone (such as the GSMArena website). Even if the IP level is low, there is no need to worry too much, many mobile phones can return to normal after air drying.

Do not use a microwave, oven, hair dryer or vacuum cleaner to prevent damage to internal components. The "rice drying method" is not reliable. Silicone desiccant (available on Amazon) may be more effective, but not foolproof.

If the phone still cannot be turned on after two days, please contact a professional repair shop. They will remove the phone, dry the parts individually and replace the damaged parts.
