It has become a highly competitive market for tablet PCs. A few brands are slogging to stand out from the crowd. Only a select few companies are staying competitive by focusing exclusively on product quality.
A tablet PC may switch on without any hassles and may take high-quality photos. It may appear to be okay. You will be surprised to know that new tablets could show symptoms of an apparent problem after the goods leave the factory to be distributed to retailers and customers. You need not have to seek a tablet repair in Montclair for minor issues. You as a user must be familiar with a few of the commonest quality issues that can affect tablets. Let us analyze the five commonest tablet PC problems and their solutions.
Broken Pixels Such as Line or Dots in the Display
The tablet and smartphone screens are made of an LCD (liquid crystal display). These screens use pixels, which is a grid of points. Each has three sub-pixels, which are green, red, and blue, which switch on and off to show colors on the screen. These pixels are powered by transistors in the tablet’s circuitry, when a transistor is faulty, then a single or a series of pixels malfunction. When you observe any spots on your tablet screen, it must be a problem with the tablet’s transistors.
Solution
This defect cannot be fixed by an end-user as internal components must be checked. This kind of tablet repair in Redlands is ideally performed by the factory, due to the risk of electric shock while tampering with transistors. Broken pixels are a tablet PC defect that a QC executive can detect easily.
Dust Inside the Camera
Dust inside the camera signifies contamination at some point during the assembly process. Often, the dust is inside the camera component. Tablet PC suppliers ask sub-suppliers to provide parts for the final product. Well, we aren’t concluding that outsourcing components are bad. However, if a sub-supplier lacks proper quality control protocols, then the quality of the finished product suffers. Maybe, the camera was contaminated before being received. So, the assembled tablet PC will shoot substandard photos.
Solution
Similar to broken pixels, dust inside the camera is also a tablet PC defect that’s easy to detect. The supplier should conduct proper incoming quality control on outsourced parts to confirm that they’re not receiving flawed components.
Foreign Material Behind Screen
If the tablet is switched on and is displaying light colors, you may observe small, blurry points. Usually, this is dust. However, it could also be dirt or residual material left from production. The reason for foreign material being on the screen is usually because of the neatness of the assembly areas in the workshops and the factory’s quality control procedures.
Solution
It’s more convenient to prevent foreign material away from a tablet during assembly than it is to remove it from the finished product. Tablet PC manufacturers must have a clean room, categorically developed to avoid environmental pollutants such as dust particles to stay away from the production process. Smaller factories may not have very strict processes to control these areas, causing more tablets affected by foreign materials inside the screen.
Overheating Batteries
Tablet batteries heat up during excessive usages, like extended use of media or web browsing. In a regular tablet, it becomes a challenge if batteries heat to the point of damaging the tablet. Often, a tablet’s outer casing could melt, and overheating may pose a fire hazard.
Solution
In the case of poor design and outdated software, predominantly in previous models, software or general design issues may cause heating of batteries beyond the tolerance level of the product. A few such tablets can be fixed by software updates. Rest of the models, with a poor design that doesn’t let adequate cooling.
Another reason for overheating batteries could be a faulty battery charger or batteries. In a few instances, it’s understandable that the battery is defective as it bulges at the sides. Else, you may find that the battery has a problem by looking at it. Battery capacity, charge, and discharge must be included in a product inspection of tablet PCs, apart from other regular tests for consumer electronics, to ensure that the product is safe.
Unresponsive Touchscreen
Touch screens are very sensitive by design. If end users report an unresponsive touch screen it’s almost as simple as the screen being scratched, dirty, or cracked. Apart from damage to the screen, it can even malfunction if it isn’t connected properly to the printed circuit board (PCB) inside.
Solution
If a touch screen is unresponsive, it is a software problem. You can hard reset and then restore to the factory’s default settings to usually fix the issue when there’s no fault with the unit. In the case of more severe software issues that occurred during the initial set up of the tablet at the factory, it must be replaced. An accelerated life cycle test can authenticate touch screen functionality over the intended lifetime of the product.
Inference
All of the above tablet PC problems can be prevented with proper due diligence and testing during and after production. Else, you may have to opt for a professional tablet repair in Lake Elsinore .
