If we buy a high-priced and sell old mobile mobile phone like a flagship smartphone, maybe we will get its own satisfaction because the sophistication of the features and quality offered is definitely the best. However, there are times when not all expensive smartphones are good and suitable for the buyer and user. As good as any sophistication of a smartphone will be wasteful and useless if it is not as needed.

For example when you buy a Samsung Galaxy Note Series, if you are a business person or an office person who needs note features, this might be very useful and supportive of work, but if you are just an ordinary user who only needs social media applications, is this useful? certainly wasteful isn’t it?

Lots of android phones that have good specifications and quality but cheap, like smartphones with brands Xiaomi, Lenovo, Asus, Evercross, Smartfren Andromax, Advan, Acer, Acer, Oppo, Axioo, Vivo, Polytron, Vivo, Huawei, Nexus, Nokia, Himax, and various other brands. So it is not strange if so many people are confused in choosing the right android because there are so many choices.
Processor or CPU (Central Processing Unit)
The main thing and that must be considered in choosing an Android smartphone is the processor used. SoC (System on Chip) is the core brain of an android smartphone system. If the CPU specifications are low then don’t be surprised if your Android smartphone feels slow and often lags even though it’s still new and doesn’t install many apps.
 
Here are tips on choosing an Android processor:

    1 Choose a processor with a well-known brand such as Qualcomm Snapdragon, Exynos, Nvidia Tegra if you have a high budget. Otherwise, you can choose a processor with the brand Mediatek (MTK) or Intel.
    Choose the highest series of chipsets that you choose, for example, if in Qualcomm Snapdragon for the low device class usually uses the 200 and 400 series, for the mid class (middle) usually use the 600 series and for the flagship class or the highest usually use the 800 series. When this article written, the highest snapdragon qualcomm is Snapdragon 821 and the latest rumor will be the Snapdragon 835 series.
    Choose chipsets with a high clockspeed of at least 1 GHz, the higher the better.
    Choose the most modern and new architecture today such as ARMv8, Cortex A53, Cortex A57 and others.
    Choose the smallest and most sophisticated manufacturing. Examples of them such as 90nm, 65nm, 45nm, 40nm, and 28nm, 14nm, 10nm.
    Also choose a processor with a large and fast cache.
    And most importantly, choose a processor with a lot of core cores of at least 2 cores (dualcore). More is better like 4 cores (quadcore), 6 cores (hexacore), 8 cores (octacore), 10 cores (decacore).

2. RAM (Random Access Memory)
If a processor or chipset works as a brain, then ram is as a memory. Ram is useful when we run various applications simultaneously. The more applications we run, the more memory is needed. With a large Ram, we can move between applications smoothly. However, if the wrong choice of ram, the android we use will feel slow and the applications we run will often get stuck and force close.

Here are tips on choosing a good and correct Android RAM:

    Choose a minimum RAM capacity of 1 GB, bigger is certainly better.
    Important! Choose the latest types of ram such as LPDDR2, LPDDR3, LPDDR4 (Higher series is faster).
    And choose RAM with high frequency (one MHz).

3. GPU (Graphics Processing Unit)

As the name implies, the GPU function is as a graphics processor. By choosing a good GPU, 2D and 3D performance on Android will be very fast and smooth. For example when we watch videos and games, there will be no lag or stuttering that will interfere if the GPU is capable. Besides smooth, using a capable GPU can also spoil our eyes because of the stunning graphic display, detail and clear.


Here are tips on choosing a high-performance Android GPU:

    Just like choosing a processor, choose a GPU with a qualified type according to the budget such as Adreno (Snapdragon), Mali (Exynos, MTK), Nvidia Tegra, VideoCore Broadcome, PowerVR and others.
    Choose the highest series of the types above, for example Adreno 540, Mali-T720 MP4, Tegra K1, PowerVR G6430 and if the budget is high, choose the newest and the fastest.
    Choose a GPU with a high Clockspeed of at least 500 MHz
    Also choose GPUs with many cores as well as processors. If in Mali, Core can be interpreted by the last letter after the type, for example MP4 means there is a cor 4.
