This is the official HTC One (E8) User Guide in English provided from the manufacturer. If you are looking for detailed technical specifications, please see our Specs page.
The new HTC One (E8) is a lower priced version of the HTC One (M8), which retains most of its premium specs, but the metal sheen is replaced with that of polycarbonate. The main duo-camera gives way to a no-frills 13MP single rear cam with a BSI sensor and f/2.2 aperture, capable of 1080p video recording. The One E8 has the same 5-inch 1080p display and runs on the same Snapdragon 801 quad-core CPU with 2GB of RAM. It has 16GB of storage on-board, along with a microSD slot with support for up to 128GB cards. The front camera remains the same 5MP selfie champ. The battery capacity is a decent 2600mAh, and since the E8 is a unibody phone, it won't be user-replaceable. The phone runs Android 4.4 KitKat with HTC Sense 6 on top and has two nano SIM slots.
