PHONES HARDWARES: Problems, Causes, Symptoms, Fix and Prevention


If you are reading this article, it is either you have a smartphone or a computer or both. We have millions of people around the world who own a phone without a computer. In this generation, you can hardly do without a phone no matter how cheap it is. The article of today will centre on the first aid of any phone hardware problems. I mean the DIY or major phones hardware issues. Prevention they say is better than cure, I will also talk about how to prevent hardware damages to your phones, symptoms of a phone with hardware issues and basic fixes.

What is a mobile phone hardware?  The phone hardware components are the physical parts or components of a phone, such as the LCD(Screen), housing, memory card, battery, Printed Circuit Board.(PCB), On/Off Switch, CPU, Ram, RF / Network IC, Flas IC, Power IC, Charging IC, Logic IC, Audio IC,  and so on, all of which are physical objects that are tangible. In a layman’s language, phone hardware(just like pc hardware) are those components of a phone that you can touch, feel, and smell.

MOBILE PHONES PROBLEMS, FIXES AND PREVENTION

In all honesty, I will personally advise you to prevent rather than cure. You will be better off averting damages to your phones than repairing them. This segment will be divided into three vis a vis: Causes(the opposite of this will be prevention meaning do the opposite of what caused the damage). symptoms /behaviour(meaning how you know that your phone has a particular hardware problem), Suggested fixes.

 

WHEN YOUR PHONE’S POWER SWITCH IS FAULTY

 

CAUSES

  • The power button is damaged

SYMPTOMS

For anyone with a phone that opens (not an iPhone) there is a band-aid solution for you to use while you’re waiting for your repairs appointment. Pull the battery out of your phone and connect it to your computer. While your phone is connected to the computer, put the battery back in and it should turn on.

SOLUTION

You’re going to need to get this one repaired too.

 CRACKED / SHATTERED SCREEN

The eyes they say is the window of the body. Same applies to the usefulness of the LCD screen to a phone. The most expensive phone is useless if the screen is shattered.

Causes of screen problems:

  • Inherent factory fault
  • Accidental damages like dropping from high impact, mistakes…
  • Design flaws of the phone
  • Lack of proper handling e.g if you have a tablet, you should know you must house it inside a full pouch….
  • Carelessness; submersion, abuse…

Symptoms of Phone with a damaged screen

  • Totally blank or black screen; it looks as if the device is powered off whereas it is on. This happens where either the screen is not well connected to the PCB or maybe the display ic is faulty. At times it may be due to the actual screen being damaged.
  • Screen with ink-like substances: A non-repairable damaged screen
  • Screen without ink but with visible lines /marks: The screen is shattered: non-reparable but usable
  • Screen touch not responsive: It may be due to damage to the whole screen or just the digitizer /calibrator

FIXES / SOLUTIONS TO SCREEN PROBLEMS

Yes, you can do it yourself only on one condition; if you are 100% certain that it is only the screen that is affected I mean, nothing is wrong with the phone’s board. Secondly, if you are changing the screen yourself, make sure you order the original from eBay , amazon or directly from the manufacturer. You should also read vidoe tutorials of how to replace screens on www.ifixit.com

  • If you are not sure if only the screen is faulty, please take it to a skilled Gsm/ Computer engineer for repair.

PREVENTING A SCREEN FROM GETTING DAMAGED

  • The surest prevention is that you must be careful overall and also endeavour to buy a phone that is under warranty.
  • Even the best water-resistant phone will crash when submerged for long. Avoid liquid spills that can corrode the section where your screen connects to the board.
  • For iPads and tablets, use a protective wallet /pouch.
  • For other phones use a pouch cover or an original tempered glass screen protector(fake tempered glass will cause harm than good eventually)
  • Men Do not put your phone into your breast pocket
  • Women do not put your phone in a bag or purse that house sharp objects.
  • Do not put your phone in your back pocket
  • Do not leave your phone lying on a chair, do not place your phone on an unkempt bed especially when you are not lying down
  • Do not hand over your phone to your super active kid without monitoring
  • Do not place your phone on a high platform that is sloppy or slippery or unsteady
  • Do not play rough or fight while your phone is on you(In fact, why shall thou fight at all?)
  • For my athletes in the house. please buy an armband carrier for phones during your workouts
  • Do not operate your phone when you are in a mob or any crowded area

Camera Lens Is Broken, Blurred Or Hazy

This is when there is noise or distortion in pictures being captured by your phone

CAUSES

  • Broken camera lens
  • Dirty camera lens

SOLUTIONS

  • If you have a hazy or scratched camera lens, the very first thing I would do is give it a really, really good clean. You’d be surprised how much of a difference that can make. And don’t just give it a quick wipe with a cloth. Get out the methylated spirits or spray and wipe and really make sure it’s clean
  • When the above fail to work, you have to replace the lens. This is the one instance that you should probably cough up the extra cash and make sure it’s repaired properly by your manufacturer. When it comes to a camera lens, quality is everything.

WATER DAMAGE

This happens when your phone is immersed in water or even submerged. No phone as at yet can boast of a permanent water-resistance. whether yours is the usual 30 minutes water resistance or not, if you found out that your phone fell into water or any liquid or soaked in your baby’s saliva, observe the following very carefully. Your phone falling into the water is not what will cause the damage in itself, what will cause the damage is the short- circuitS that will occur when your phone’s electricity meets water that causes the problems.

PREVENTION

  • Take your phone far away from water or other liquid.
  • Women know a safe place to put your phone while in the kitchen or while doing laundry
