Last year's HTC flagship line-up consisted of the One, One mini and One Max, so it's only logical after the One (M8) the rest of the phones to have their respective successors. And it only took a few days after HTC officially announced the M8, for rumors about the One (M8) mini to start piling up.
Firstly, Swedish carrier Telia listed the One (M8) mini on its blog referring to it as packing support for HD voice. Later, it was removed with a Telia employee explaining the listing as an error. Of course, there's a chance that this is actually the case, but it's more likely that someone put the listing far earlier than they are supposed to.
Meanwhile, the famous evleaks account has confirmed the existence of the One (M8) mini in a tweet, saying "One (M8) mini: check." Sadly, no specifications were shared in the tweet.
Apart from having its name confirmed, there isn't much else at this point regarding the One (M8) mini. We'll keep you in the loop as soon as new info comes in.
Unfortunately the person I spoke to couldn't reveal any specs. I'll continue to research and let GSMA know if I find anything :)
I did the same last year and I'll do it also this year (ignoring their products). I have a HTC ONE X and I'm very pleased with it (I put on it HTC ONE X+'s battery). I will not switch to another manufacturer, I must admit that I'm a big fan of Sense ...
I read somewhere that HTC M8 mini will have the same specs as the M8, but smaller screen size and dimensions. If that is the case, then I'm sold. Also, if they could fix the camera, bump it to 8-13 MP, that would be the perfect choice.
