HTC, Samsung, Sony Ericsson, Motorola, Acer, and various other brands, offering gadgets in the form of Smartphone 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.
Surely you 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. So, only the processors that have been well recognized by the Android OS 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 HD (high quality) game for Android only works with a processor speed of 1 GHz or more. Then, to what use the processor 600-800HMz? For Android Smartphone 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 Android Tablets and Android Smartphone. 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” well by 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.
The 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, but uses low capable processor and a VGA, you will feel the 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 on the processor 1 GHz up, 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 is one of the 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.

Type of screen will affect the quality of appearance. AMOLED screen, which is used by Samsung, for example, displays 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. That’s 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.
Internal storage is internal memory that can be used to install the app
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.
MicroSD memory card is commonly used Android device
The important thing to remember, increasing the memory card is not making the bigger RAM. So increasing the capacity of 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 the 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, at least currently, must have a 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 like Honeycomb (3.x) and would be better if the OS will get ice cream sandwiches for the tablet as well. Why is that? Because, the specific OS for tablets will give the appearance, that utilize large screen and high resolution.
Android Honeycomb structure is designed specifically for the Tablet
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 will 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 connectivity)
There are several important features that have to be able to enjoy the ability of your Smartphone or tablet. Not all Android devices have all the features below. The price of the device itself strongly influences the features it has.
Of course the camera must have an Android device. You can upload photos directly to Facebook, Twitter or other social networks. If the picture is good enough, you might be able to utilize your device as a digital camera to record the important moments.
A good camera is essential equipment for Android devices
The second camera is a camera facing the user’s Android devices. These cameras generally produce low-resolution images. However, it can be very useful if you want to do video chat (eg Skype).
WiFi is of course necessary and common to all Android devices. WiFi becomes very important when you need a high speed connection such as while doing the installation app from the market or even streaming video.
Bluetooth may have started forgotten. However, given the size of the majority of Android devices is now large enough, a bluetooth headset would be an ideal partner.
Accelerometer is a sensor that makes your device “realize” placement position. This tool can be used for a variety of applications, ranging from games to the GPS.
GPS is commonly found on all Android devices with 3G capability. You can use Google Maps as a free GPS map from Google and make your device the a direction that is very accurate.
Google Maps is available free to all android devices
Proximity sensor is a sensor that can detect the existence of objects close to your device. This is very useful for Smartphone. Upon receipt of the phone and stick it to the ear, proximity sensor is activated and your device is directly off the screen and touch screen. This avoids the possibility of depressed and at the same screen save battery power usage.
Electronic compass will make the GPS function be increasingly better. Even at rest, your device will “realize” what direction he faced.
Sorting and Selecting
In the end, choose an Android Smartphone or tablet does require extra flair. You even have a little more observant than choosing a notebook. Throw a few questions yourself:
- What funds are available? It’s certainly important to limit ourselves so as not to exceed the target of their money when buying.
- What functions do you most need? For example, if there is a need for the GPS function on the car, the screen is a bit large be essential (in addition to the GPS feature itself).
- Do you want to use for heavy gaming? If yes, the device with a minimum of dual core is the choice.
- Do you want to use it as a regular cell phone with more capabilities only? Possible, an Android smartphone with a 600-800 MHz processor is adequate.
- Do you want to use it as a means to enjoy multimedia presentations and small-time? This means a tablet 7 “-10″ is the best choice.
And a list of questions continues until you get the right device.
