RAM:
Ram is the main thing you should consider before purchasing a new smartphone. The higher the RAM variant you select the device will perform better. An android device must have at least 1.5 GB of RAM for lag-free performance. If you are a normal user like calling, social media browsing is your preference, then 1.5 to 3 GB is enough for you. Another is 2GB to 4GB for multitasking and low-end games and some high-end games with low specifications. If you are a pro gamer, then you should purchase 6GB to a higher variant of RAMs for outstanding performance.
