The new HTC Desire 620 is coming in early 2015 and is poised to be a successor to the Desire 610. The phone's meant to carry on with the 610's mission by providing an "an affordable smartphone that balances quality performance with stunning design."
The phone's an upgrade in most ways over its colorful predecessor, with a 64-bit quad-core Qualcomm Snapdragon 410 processor clocked at 1.2GHz, 1GB of RAM, and 8GB of storage (plus microSD expansion). The screen is a 5-inch number of unspecified "high resolution", flanked by HTC's signature stereo BoomSound speakers. There's a 8MP camera on the back with 5MP up front, both capable of 1080p video. As far as radios are concerned, the phone contains an LTE Advanced radio capable of downloads up to 150Mbps, but good luck getting that in real life.
But wait, there's more! There's also a HTC Desire 620g coming. It's much the same phone, though it contains supports dual SIM cards and is powered by an unspecified 1.7GHz octa-core processor and drops the LTE for just 3G connectivity.
Both versions of the Desire 620 will be available in Santorini White (white with blue accents), Marble White (white with gray accents), Tuxedo Gray (matte gray with light gray accents), and Saffron Gray (matte gray with orange accents). Exact release dates and pricing have not yet been announced.
