This new HTC E9 is made for those who don't need Quad HD screens
While it keeps the same screen size of the One E9+, the newer E9 doesn't offer a Quad HD (1440 x 2560) resolution, instead coming with a 720 x 1280 pixels one. This obviously means that the handset will be cheaper, though we don't have details about its exact price.
Just like its high-end brother, the One E9st runs Android Lollipop, and has dual front-facing speakers. Its processor is also an octa-core unit, but one clocked at 1.5 GHz, not at 2 GHz. Other than that, the new handset features a 13 MP rear camera, a 4 MP UltraPixel front-facing camera, 2 GB of RAM, and 16 GB of expandable internal memory.
The HTC E9st that we're seeing below is made for China Mobile, but this doesn't necessarily mean the smartphone is a China-only product.
