Damn Mediatek, damn!
Mediatek Helio X10 chipsets are to be blamed for wi-fi latching problems.
I’ve been reading news about Helio X10 chipsets having an issue with latching on to the wi-fi, across phones like Redmi Note 3, HTC One, Le1S, etc.
Read Mediatek accepts it screwed up - http://en.expreview.com/?p=399.
Although they’ve admitted it on their blogs, later company must have got a lot of criticism and has reached out to the press saying there is no such issue. But we know there is no smoke without fire.
Maybe creo could have made a better choice by not putting Mediatek HelioX10 chipset.
