It looks like a new HTC handset has appeared over at TENAA, the Chinese equivalent of the FCC. The mid-range handset is known as the HTC 603e and is believed to possibly be a successor to the HTC One SU.
Although it isn’t going to take anyone’s breath away with its specs, the phone features reasonably capable hardware powered by a 1.15GHz dual-core CPU and 1GB of RAM. Other specs include a 5MP front cam, 2MP rear cam, a 4.3-inch display with a resolution of 480 x 800, microSD and Android 4.1 Jelly Bean.
Its worth noting that the overall styling of the handset seems to be pretty in-line with the upcoming HTC M7 and HTC M4. This has lead to some speculation that this could be the M4, or perhaps a variant of it. The problem with that idea is that the specs for the 603e don’t seem to match up with the stronger specs that were recently leaked for the M4.
At the moment we know very little about the HTC 603e’s pricing, release schedule or whether or not it is directly related to the HTC M4 or not. Odds are that we could learn more at MWC later this month.
