At first this phone is the copy of iphone 7, and the hardware specification is worst. And they are as follows: -
The processor used in this phone is 5 year old so that it cannot match the this generation apps or it cannot handle heavy games or the performance will be worst.
4GB RAM , if the processor is only of older generation then even the DDR 5 RAM will not be helpful.
Front Camera 20MP this are just numbers and in actual quality they looks like 5MP camera, quality is not good for better picture quality go for Moto G4 or G5 plus .
