HTC is expected to announce the HTC 10 flagship on April 12, but it seems like the OEM has another device to unveil to highlight the occasion.

Only recently, we reported that a leaked image of the HTC 10 shows the handset having impressive AnTuTu benchmark results, beating huge rivals that include Apple's iPhone 6s and Samsung's Galaxy S7 edge.

HTC also received FCC certification on its two HTC 10 models that were identified as 2PS6200 and 2PS6500, although the company has yet to make a confirmation on the said model numbers.

The latest rumor states that the HTC 10 will launch with a slightly cheaper variant that will come equipped with a Qualcomm Snapdragon 652 SoC, and it now seems that model may in fact be a Desire addition. The information comes from ROM developer LlabTooFer (@LlabTooFeR) who tweeted that HTC will release a handset code-named "A56," which will be under the company's Desire lineup.

"Along with Perfume, HTC will release another Desire phone, [code name] is A56. This device will have both Single and DualSIM versions," tweeted Llab TooFer.

In February, we also reported how HTC's trio of new handsets from its Desire lineup became glammed up with streetwear fashion-inspired designs. TheDesire 530, Desire 630 and Desire 825 all feature a micro splash effect on their polycarbonate build.

"HTC has built its reputation on pairing industry-leading design with smart features," says Chialin Chang, president of sales at HTC. "But with customers also seeking personalization, and individuality in addition to treating their phones as fashion accessories, we have needed to create something different. So, today we're launching the most unique Desire devices."

HTC's Desire lineup of devices covers a wide range of device classes, which could start from the entry-level and end up to the near high-end right before the threshold that would cover the mid-range and flagship levels.

It is speculated that the mysterious handset that would launch alongside the HTC 10 will be a Desire smartphone and not a variant of the flagship. Bearing the moniker A56, the Desire handset could just belong to the higher end of the lineup's mid-range spectrum.

With HTC's April event only a few days away, it is but natural to expect that more details on the mysterious phone would be revealed prior to the event. HTC is holding the event on April 12 in three locations simultaneously: New York (8 a.m.), London (1 p.m.) and Taipei (8 p.m.).

Along with Perfume, HTC will release another Desire phone, codename is A56. This device will have both Single and DualSIM versions.
