Samsung can be only compared with Samsung. A person using Samsung never
shifts to Xiaomi or oppo vivo. Samsung is brand class and fully
dependable. I am using samsung from last 10 years and I don't even
prefer any other android brand. I can just thin...
Well I will suggest always keep your 2nd sim on 2g and main sim on 4g.
Battery backup of M30 is very good in 2g and 3g modes. 5000mAh can be
very useful as in M30.
