Nokia has released a teaser image for an upcoming announcement, potentially revealing a new QWERTY smartphone, although all the signs point to this device falling under the Asha range of low-end quasi-smartphones, as opposed to their flagship Windows Phone Lumia line-up., Neowin reports.

The image released shows off a rounded yellow phone with visible Z and Shift keys, employing a similar style to previous devices in their Asha range.

Another hint that this device probably isn't a Lumia comes from the fact that the phone's unveiling, scheduled to be held at 7am GMT on Wednesday, April 24 is being done by Nokia's Mobile Phones team rather than the Lumia team.

Also, the particular choice of time for the announcement, which is early in the morning for those living in North America, hints that this device is designated for an Asian launch, Neowin says.
