Can a smartphone really have a screen-to-body ratio above 100%? This seems to be the case with the upcoming Xiaomi Mi MIX Alpha, at least from the company’s point of view. The MIX Alpha will be released on September 24th alongside other devices. According to a recent Weibo post from Lu Weibing, he seems to suggest that the screen ratio of this smartphone will exceed 100%. His words “…Xiaomi MIX Alpha proves that the 100% upper limit is not the traditional concept of screen ratio…”.

It seems that the entire front surface of this phone will be the display which gives a 100% display ratio. However, the side of this phone is also part of the display. This thin side-display could be the reason behind Xiaomi’s claim of a >100% screen ratio. According to Xiaomi’s CEO, Lei Jun said, the Xiaomi Mi MIX Alpha is not a foldable phone. This means that this smartphone obviously uses a waterfall display as we have seen on the Huawei Mate 30 Pro. For now, we do not know if Xiaomi has a solution to the issue of accidental touch.
In addition, the MIX Alpha will support 5G network and will come with the Qualcomm Xiaolong 855+ flagship platform. It is worth mentioning that Mi MIX Alpha may be the official “5G era concept mobile phone” that was previously promoted, which means that it may not be mass-produced. In addition, the MIX Alpha is not a regular iterative product of the MIX series. Thus, there is a possibility that the Xiaomi Mi MIX 4 will still arrive on September 24th. If this is the case, then Mi MIX 4 should come with a 100MP camera.
Marketing gibberish.
Move along, nothing to see here.
