Just search on google. The answer is as below. If you have different idea, please feel free to leave your comment. As defined by iFixit, which is a platform share the teardown guideline for all equipment. Repairability is rated on a scale of zero to 10 — ten being the easiest to repair and zero being the hardest. To receive a good score, a device must be easy to disassemble. A service manual should be available, and points are deducted or awarded based on difficulty to open and complexity in replacing major components. Component modularity and ability to upgrade easily can boost the device's score, while use of non-proprietary tools for servicing can reduce it. iFixit's list doesn't cover all the smartphones on the market, but it does address most of those available in the United States. According to iFixit, the repairability champion is Motorola, whose Droid Bionic and Atrix 4G are the only devices on the list with nine points. Samsung's Galaxy S4, as well as...

How to open and disassemble any mobile cell phone including Nokia, Samsung, Motorola, China Mobile Phones or any other brand of cell phone from any mobile cell phone manufacturer is basically same with slight change in the process.

The tools you will need are: 1.      T5, T6 and Forehead Precision Screwdriver . A screwdriver set or kit can be very useful. These screwdrivers must have magnetic tip. 2.      Mobil Phone Opener 3.      Tweezers 4.      Antistatic Wrist Strap 5.      Antistatic Hand Gloves 6.      Antistatic or ESD-Safe Mat 7.      ESD-Safe Apron 8.      ESD-Safe Footwear NOTE : It is very important to use only Antistatic or ESD-Safe tools to open an...

It is not difficult to check LCD (Display) of a cell phone or a tablet. LCDs being delicate tend to crack, leave blots or simply sop working. So if its is broken or cracked, you can see its broken manually. Even if there is a blot on it, you can see it physically. But what if its looking good and still there is no graphics on the display? The problem may be either the LCD is faulty or there is some problem in the PCB. So how do we test it? A faulty LCD can be of the following types: Cracked or broken A blot (round in shape which will spread rapidly!) Blank display with no graphics. An LCD with just graphics and no light (LED) glowing on it. You can check LCD of a cell phone by any of the below methods 1. LCD Testers: There are testing machines available in the market for checking of LCDs. The problem here is that as all models have different LCDs, you will need to buy an LCD tester machine for all types and models and will run into hundreds! As all LCDs of smartphones, ...

Are you planning on taking a skiing adventure this winter? With the holiday season around the corner, it is probably the best time to go for a much-awaited break. Unfortunately, most electronic owners are unaware of the effect cold weather can have on their devices – including cell phones and tablets. Cold weather symptoms could include a sluggish LCD performance and poor battery performance; cold weather can even damage your device permanently. How cold is too cold for your mobile device? All the major cell phone manufacturers warn about using their products in cold temperatures and offer operational temperature guidelines. For instance, Apple provides a temperature range of 0 to 35 degree Celsius for their devices and are not covered under warranty if you use it in conditions that are any colder or warmer. A little more lenient, Nokia offers an operational temperature range of -10 to 55 degrees Celsius while Samsung suggests -20 to 50 degrees Celsius. Why such a broad ...

One of the most common misconceptions we see in the iPhone repair business is the true meaning and understanding of the definition of Non-Original LCD Screens and Original (OEM) LCD Screens. It seems every company that sells LCD screens or buys back broken LCD screens uses slightly different terminology. If you’re a bit unsure, don’t panic! We’ll try to define the root differences between the various stock conditions in hopes that some sense of common knowledge is put in place. Why so Many Different LCD Conditions and Grading Scales? It boils down to three reasons: culture differences, marketing and name brand copyright infringement. Culture Differences – Most LCD screens are manufactured or reclaimed to be refurbished in the Asian market. Right out of the gate, there is a barrier of culture and language barriers that simply don’t align with other nations terms relating to cell phone replacement parts. For example: the phrase OEM (Original Equipment Manufacturer) seems...

I recently overheard a woman on the subway telling her friend that her toddler “swipes” everything in their house – the coffee table, books, plates and even her own mother, trying to make her disappear like an image on a touch screen. The story got me thinking that for many of us, our knowledge of what’s going on behind that glossy display isn’t much more than a toddler’s. Before I started researching how touch screens worked, I figured there was one universal technology behind the “swipable” phenomenon. Instead it turns out there are half a dozen, and more being researched every day. The two most commonly used systems are resistive and capacitive touch screens. For the sake of simplicity, I will focus here on these two systems and finish with where experts think touch screen technology is headed. 1. Resistive These are the most basic and common touch screens, the ones used at ATMs and supermarkets, that require an electronic signature with that small grey pen. These screens lite...

Sometimes you will see these terms being used, but S-IPS is still widely used as an umbrella for modern IPS panels. In 2002 Advanced Super IPS (AS-IPS) boosted the amount of light transmitted from the backlighting by around 30% compared with the standard Super IPS technology developed in 1998. This did help boost contrast ratios somewhat, but they could still not compete with VA panel types. In 2005 with the introduction of RTC technologies (Overdrive Circuitry - ODC) and dynamic contrast ratios, LG.Display started to produce their so called "Enhanced IPS" (E-IPS, not to be confused with e-IPS) panels. Pixel response times were reduced across G2G transitions to as low as 5ms on paper. Enhanced S-IPS builds on S-IPS technology by providing the same 178° viewing angle from above and below and to the sides, and greatly improves the off-axis viewing experience by delivering crisp images with minimal colour shift, even when viewed from off-axis angles such as 45°. You will rar...
