Our own stats say it's clear: behind Xiaomi, Doogee is the most sold brand of Chinese smartphones online, when just taking into account sales to the foreign market.
The strategy of Doogee so far has been quite clear: to offer better products than their competitors at better prices. And they've even managed to offer their products before their competitors did, innovating and staying ahead of them.
This has worked quite good for them. They have managed to get one of the best results a Chinese phone company has ever gotten on the foreign market and their phones have one of the lowest return rates. Also they have started offering local after sales service in many countries and officially selling their phones in many other countries, which has made it even easier for customers to order a Doogee phone.
