The Lava X3 is without a doubt one of the best budget smartphones today. People have a tough time selecting budget smartphones because most of them are pretty useless, to be honest. But Lava X3 is one of those rare budget smartphones that actually provide the performance it promises. The design of the smartphone is good, and what I was surprised the most about was the build quality of the device. The camera performs just fine, and the MediaTek processor provides decent performance. I have not yet experienced any kind of lag or overheating issues. The battery should have been bigger, but due to the efficiency of the smartphone, the 4000mh backup also seems to last long.
