Tips Understanding Android Smartphone Tablet Specifications Before Buying
Tips Understanding Android Smartphone Tablet Specifications Before Buying
HTC, Samsung, Sony Ericsson, Motorola, Acer, and offers a variety of other brands of smartphones gadgets and / or a tablet PC based on Android. The problem is, how to choose the most appropriate? All manufacturers offer different specifications. Therefore, we describe the meaning of the specifications that have these products in general.
Processor and VGA
You certainly can easily identify with the processor for the PC or notebook, is not it? Well, for Android tablets, the processor also plays an important role.
The type and brand of processor it plays an important role. Not all processors 1 GHz can offer the same performance. Why is that? This is due to optimization of the operating system that is still in its early stages. Thus, only the processors that have been well recognized by the Android OS that can offer the best performance. NVIDIA Tegra, Qualcomm, and TI OMAP processors are examples that can have very good performance.
The processor speed is also a very important thing. Average game HD (high quality) for Android only works with a processor speed of 1 GHz or more. Then, to what use the processor 600-800HMz? For smartphones with low-resolution screen (480 × 320 to 320 × 240) processor with a speed of 600-800 MHz is still pretty good. Of course, in this range, 800 MHz will still be the best choice.
Multi-core processors are the best option to deal with the application or even the latest games. Currently, dual-core processor with a minimum speed of 1 GHz has begun to be easily found on the tablets and smartphones. Availability of 2 core processor makes the process of multitasking (doing multiple commands simultaneously) becomes easier and lighter.
VGA is available in the processor also determines performance. Just by choosing a processor, a VGA "known" by both the Android OS will offer better performance. For example, 600-800 MHz Qualcomm MSM7227 processor with Adreno 200 VGA still will have better performance than the processor and VGA alloys that are less known.
SCREEN
The higher the screen resolution and physical size, would be the better, right? The answer is yes and no. The answer to this question depends on many things.
High-resolution screen will drain the VGA capabilities available in the processor. So, if you choose a tablet with a high resolution VGA + processor but use low-capable, you will experience performance problems. For example, the screen with a resolution of 800 × 480 upwards will feel heavy when only using 600 MHz processors only. The new comfort can be found at 1 GHz processor blend upwards and VGA are "known" by both the Android OS.
Low screen resolution found on some entry-level smartphone (480 x 320 up to 320 × 240) should not require excessive force from the processor and VGA.
Screen pixel density are things that affect the display quality of the resolution. Pixel density is calculated from the number of pixels that exist in the physical area of ??the screen. For example, Samsung Galaxy Y with 3.0-inch screen (320x240pixel) has a density of about 133ppi. While Sony Ericsson Xperia Ray with 3.3-inch screen (854 × 480 pixels) has a density of about 297ppi. Note: The density in the range of 300ppi is called Apple as a "retinal display" of being able to display images and text with a very tightly, without showing the rigid corners.
This type of screen will affect the quality of appearance. Samsungs AMOLED display is used, for example, displays an excellent image brightness.
The touch screen is also a consideration that should be considered. Distinguish between capacitive and resistive touch screen. Convenient to use the touch screen is capacitive due to a very good response. Of course, the capacitive touch screen is not exactly cheap. Thats why there is still a lower-priced tablet that uses a resistive screen.
MEMORY
Differentiate between RAM memory and internal memory for storage. RAM is memory that is used to perform the commands given. Internal memory for storage is the memory used to store the software (app) is installed.
Memory cards can be used to store the software (app) and other files (video, photos, etc.). However, keep in mind that not every app can be installed on the memory card. If could also, generally there will be a fraction of the app that still must be placed in internal memory for storage.
The important thing to remember, increasing the memory card is not making a bigger RAM. So pengingkatan capacity memory card is not a direct impact on overall performance.
OS (operating system)
Why bother with the OS? Therefore, the latest OS can make the performance become better and can make your device has better features too. For example, Android 2.1 have not been able to do wifi tethering and move the app to memory card. Both of these new features can be found (natively) on Android 2.2 (Froyo). Meanwhile, the Android 2.3 (gingerbread) has a power saving feature better.
Android Smartphone must have at least this time gingerbread OS (2.3.x) or even ice cream sandwich (4.0). Optimization and power saving features of the new OS is required to use a device that is also your cell phone.
Tablet Android now should have a specific OS tablet is Honeycomb (3.x) and would be better if the promised OS will get ice cream sandwiches for the tablet as well. Why is that? Because, the OS specific to this tablet will give the appearance that utilize large screen and high resolution.
It is also important to consider is the new OS will generally give the optimization of the processor and VGA is used. So, it could be with the OS upgrade you get higher performance.
connectors
Connectivity is available on an Android device can determine how far these devices can be developed by the function.
HDMI port will allow you to connect your Android device to a monitor or TV that has HDMI port. Audio and video from your device can be transferred to a monitor or TV.
Support USB OTG can make your device is connected to an external storage or even a keyboard and mouse.
3.5mm audio port is usually available on all Android devices. This allows you to use various types of headphones or even connect it to other audio systems.
Memory card slot is of course important for you to increase data storage capacity (and app) on your device.
Important feature (especially for a device with 3G
