Repair: SmartPhone Cracked or Broken Screen

Broken Screen

Varying degrees of damage can exist on a cell phone’s screen, from a minor fracture to what looks like a puncture wound. A lot of people can live with a small divot or crack on their de - vice’s screen without it affecting them. Let’s be honest, repairs aren’t always cheap and parts are expensive.

Bigger issues are not so easy to live with. Glass gradually chipping away will expose sensitive regions on the phone, components beneath the glass can break, and a broken touchscreen can render a smartphone com - pletely useless.

SMARTPHONE CRACKED

Solutions


Cell phone screens include the glass, digitizer, lights and a lot of other small components. On some touchscreen devices, the factory fuses all of these parts together because it means that they can manufacture the phones faster. Instead of just replacing the glass, you now need to replace the entire screen assembly, which includes correctly attaching it to the phone’s motherboard.

Proper knowledge of your particular device and how it was manufactured is key to per - forming the correct screen repairs.

The majority of repairs (for broken screens and other problems) require opening your device, so we have included some tips for that at the end of this guide. Before beginning, turn off the cell phone!

Replacing the Glass & Other Components 


If the glass covering your mobile device’s screen broke, and it is not fused to the screen assembly, you may be in some luck. Cheap replacement glass is available online, as well as video tuto - rials for many different models. Likely, you will need to use a suction to pull the glass from the screen. Use care when reapplying the glass so it looks flawless.

Lights and digitizers beneath the glass can be more troublesome to repair or replace. Lights can be soldered or screwed to other pieces, including the motherboard; while digitizers are often wired to the device’s computer. Once again, use care, being especially careful not to damage other parts of the phone.

Fused Touchscreens 

How the touchscreen is attached to the device is up to manufacturer. Likely, you will need a suc - tion device or a small screwdriver to remove the screen assembly. The digitizer will be linked to the cell phone’s computer with a flex cable. Take careful note of how the touchscreen is positioned in the device before you proceed with extraction.

WATER DAMAGE

Puddles, toilets and other pools of water have claimed the lives of countless cell phones. We all dread it will happen to our devices. If you are so unfortunate, our specialists have a few tips for trying to revive your phone.

Water and other liquids can enter your phone through seams in the case, such as by the screen or battery, or through the micro-USB port and other openings. Just a little exposure can be as damaging as dunking it in a pool.

Common Forms of Damage

Short Circuits Liquids such as water are conductive and will wreck havoc on the circuitry inside the phone. Electricity follows the path of least resistance, which is why touching a live electrical wire while you are grounded will result in a nasty shock. Water seeps between the gaps in the circuitry and, being conductive, allows electri - cal signals to jump to a nearby, more attractive destination rather than following the paths provided by the phone’s circuit board. The circuit has been cut short; or, a “short circuit” has formed.

Short circuits are caused when two compo - nents inside the phone that are not supposed to interact do interact because the water has allowed electricity to conduct between them. Usually, cell phones have no safeguards to protect against short circuits.

Corrosion

Another type of damage is more long-term than the immediate effects of a short circuit. Rust is caused by water coming into contact with metal, and then this metal is exposed to air, which cor - rodes the metal through oxidation. Rusty metals are not as conductive for electricity as a clean, polished surface. Cell phone charging ports, in - ternal circuitry and other components rely heavily on metallic connections and copper wiring. Cor - rosion affects cell phones just as much as it does any other electronic device.

Other 
Contrary to popular belief, you cannot “fry” a cell phone by exposing it to water. You won’t find any smoke coming out of your device any time soon.
Solutions
Besides accidents, a lot of people imagine a cell phone vibrating in a drinking glass when they think of water damage. It’s true, if you place a cell phone in a glass, there’s a good chance that it will continue working while it’s soaked in liquid.

A popular remedy is to fill a plastic bag or cov - ered container full of rice, insert the cell phone, and surround it with the grains. The idea is that the rice will absorb the liquid. Your cell phone may work for a while after that, but maybe not for long. Without proper airflow, the liquid doesn’t go very far and enough of it can linger inside the cell phone, and corrode the internal components.

Solutions Continued 
Leaving the device in the sun or letting it dry in another natural way will still invite corrosion to take over. So will taking canned air or some other kind of air blower and using it to push the liquid out. 

Pouring rubbing alcohol or another quick-dry - ing household cleaner into the cell phone has some pluses and minuses as well. Liquid trapped in the phone may mix with the alcohol and evaporate, but absolutely no kind of liquid is meant to enter your phone. 
Household cleaners can eat away parts or cause more damage, anyways. 

Opening the cell phone and cleaning the inte - rior is the only complete way to fix water dam - age. Please turn off the cell phone before you do so. We explain this more in a later section.
