Screen quality
If you're shopping for an inexpensive Android tablet, here are some tips for avoiding a lemon.
Screen quality
When it comes to tablets,online wholesale electronic the screen is everything--your display, your user interface, your keyboard.
By sight alone, it's difficult to distinguish a goodif screen from a bad one. A lot of the critical technology is out of sight. Check the specs. Is the touch screen capacitive (like an iPad or Galaxy Tab) or resistive (like a supermarket credit card reader)? Does the screen support multitouch input for zooming photos, maps, and Web pages with a pinch? What's the resolution? If the tablet's specs don't call out these details, assume the news isn't good.
Some details are cosmetic. For this Maylong M-150 (aka, the Walgreens tablet), the warped, uneven surface of the screen is a telltale sign that cheap plastic was used. Premium tablets, such as the iPad, Galaxy Tab, and Dell Streak, typically use glass to cover their displays, or Dow Corning's extremely durable Gorilla Glass.wholesale electronic online
Not all plastic screens are bad, but the cheaper ones are more prone to wear and warping.
Port check
Check the ports on the tablet. Here on the Maylong M-150, you can see sockets for the power adapter and headphones, two speaker grilles, a mysterious dock connector that looks similar to the iPad's, and a microSD card slot.
Seem about right? How about a USB port for connecting to a computer or recharging? The specs list two USB ports and an Ethernet port, but where are they? Turns out that mysterious dock connector isn't what you'd think.
Adapters
In this example, the manufacturer offloads USB and Ethernet support to an awkward dock adapter. Even with the adapter, there's still no method for performing a basic sync between the tablet and your computer. The best option available is to transfer content from your computer to a microSD card.
