The list above is a row of Android smartphones based on 4GB RAM and 64GB ROM which can be purchased through marketplaces and offline stores circulating in the world.

Even more interesting, in the future there will be several releases of the latest mobile phones in 2021 with various specifications and uses at lower prices.

In choosing a cellphone, you definitely need to choose a product that suits your daily needs, for example the need for entertainment, education, photography, or even for gaming.

The selection of an android phone should be based on market research. Users also have to determine the period of use of an Android phone if they want to buy a new one.

Here we provide tips for choosing the best 4GB RAM Android phone in 2021 so that users don’t waste money on unnecessary things:

1. Chipset Used
Maybe for some people, the chipset is not quite influential in getting the experience of using a smartphone.

Even though according to technology experts, the chipset and GPU used on Android devices greatly determine the performance results of the cellphone.

The daily use of the user also determines how the cellphone performs. Users don’t need to worry about this chipset problem.

Because the chipset in a smartphone is actually needed to process something heavy, if the user doesn’t need the device to process the system quickly, then this doesn’t need to be a problem.

2. RAM (Random Access Memory)
RAM is the memory used by Android to read, store and process all forms of system transactions that aim to expedite the use of the device.

In an analogy, RAM is the digestive system + the brain that digests food in the body. Of course this is very important.

When there is a lot of food / data that we digest, the body also needs the capacity to launch the process, provide a way, and then release it in the form of power so that all applications and systems contained in the body / device become healthier.

But again, RAM capacity is required in certain circumstances. Users must find the requirements needed so that RAM management runs optimally.

  • Camera, Screen, Battery Capacity, Internal Memory, and OS Version
    Camera use: it needs to be improved, but again the daily use needs will not be affected by this.
  • Screen: a large, clear screen with a high refresh rate allows users to experience more satisfying video watching, entertainment, and gaming. Screen also has an important role in maintaining eye health. So, choose carefully when using the screen when choosing an android cellphone.
  • Battery Capacity: A large, strong and durable battery has a high lifespan, and vice versa. If users feel they need a smart phone to accompany their daily lives as a whole, then a large capacity battery and a fast charging system are needed.
  • Internal memory and OS version: these two things are quite continuous, Internal memory is the data storage capacity in Android which will be processed using the OS version in it.

This usage depends again on the user’s needs. Choose wisely, large internal memory with the best OS. Or standard internal memory but has a mediocre OS according to budget and needs. Source >>> Smartphone Murah.
