The most common issue of these phone is too heating . I didn’t like these phone . As compared to its price company given it only Mediatek processor and not a latest snapdragon. Camera have not efficient clarity .Battery backup is poor. As it don’t have super battery backup like Redmi and like Motorola mobile phones . Sound quality is good . Cost of these mobile is much more . Often hang during playing high performance games . Pls don’t buy these costly phone look for another rather than it .
