Samsung’s Answer to Xiaomi – The Galaxy M Series

The year 2018 was a tough one for Smartphone giants like Samsung and Apple. In 2018, Huawei grabbed the 2nd spot from Apple to become the 2nd most popular smartphone brand in the world. At the same time, Xiaomi grabbed the top spot from Samsung in India to become India’s most popular smartphone brand. The reason for Samsung to push itself to the second spot is not because its no making great phones. The reason is the price point of Samsung Galaxy handsets. What Samsung sells for $500, Xiaomi sells it for $250. This is what attracts the Indian millenials as they look for “Value for Money”.

Samsung realised that its not going to succeed with its current lineup of smartphones. The South Korean giant decided to come up with a whole new series of smartphones at a whole new price point. This is when the idea of Samsung Galaxy M series was dropped in by Samsung. Samsung kept on teasing the Galaxy M series for quite a while.

Before launching the Galaxy M10 and Galaxy M20 smartphones, Samsung ensured that these phones are purely going to be for millenials.
