VIVO Y21 is a not compact phone by vivo because the phone has a variety ofnproblems like the network coverage of this phone is very bad .
The phone uses a mediatek processor which offers very low power because of this the the phone lags while multitasking and heavy gaming.
The phone heats a while gaming the costumer service of vivo is not good my battery drains too fast when I got checked it they replace some parts but took a long time for that which was not accepted.
The cost of phone is very high as compared to its range of features which is very less also the ease of use is zero .
