Chinese manufacturer Xiaomi has apparently sold over 15 million units of its popular MI-2 smartphone. Although the handset is available for purchase in multiple markets, the device sold predominantly in China and its neighboring regions. Part of the reason for the handset’s massive success is its ultra-low price tag.

The Sony Xperia Z2 was recently announced at the MWC event in Barcelona with a lot spoken about the smartphone’s design (more of the same), camera and the processor. But not a lot was discussed about the handset’s front facing stereo speakers. A new video has now popped up on YouTube which compares the speaker of the Xperia Z2 with the HTC One.

A new rumor claims that HTC is already working on a successor for the now forgotten Butterfly S smartphone. This handset is believed to be carrying the model number ‘GLU2’ and could be headed towards Japanese carrier KDDI first.

The Sony Xperia Z2 is not even a week old and we’re already hearing of a successor. According to a Sony Mobile official, the company is planning to launch a new flagship every six months, which means that the Xperia Z2 will no longer be the best Sony smartphone in the market by September-October this year.

Chinese manufacturer OnePlus announced its plans to launch an Android smartphone called the One last month. This handset is currently being developed with the CyanogenMod team and is gearing up for a launch in the coming months. And today, the CEO of the company, Pete Lau has clarified the initial reports about its pricing.
