In spite of being one of Samsung's best smartphones to date, the Galaxy Note 5 left a few people disappointed with its move to a smaller battery and away from microSD storage expansion. Oppo is now stepping in to fill the void left by the Note by introducing the 6-inch R7 Plus, a smartphone with a 4,100mAh battery and a microSD option.

The R7 Plus comes in a unibody enclosure made out of a magnesium-aluminum alloy, which is punctuated by a 13-megapixel camera module and a fingerprint sensor on the back. Up front, the 6-inch AMOLED display has a 1080p resolution and a subtle curve to its edges, which Oppo describes as evoking the grace and tactile feel of a violin's neck.

3GB of RAM and 32GB of storage come as standard, with the latter upgradeable by up to 128GB more via the microSD card slot. There's a tradeoff to be made, though, as using the memory expansion slot takes up the space provided for a second nano-SIM. The processor inside the R7 Plus is Qualcomm's Snapdragon 615, which should prove sufficient for most purposes, but doesn't quite match up to the elevated standard set by this phone's massive battery and high-end construction.

The biggest shortcoming of the Oppo R7 Plus, though, might be the lack of 4G support for the US. European and North American fans will be able to buy it via the Oppo Style online store, but Americans will only be able to use it on T-Mobile or AT&T without LTE. The R7 Plus is on sale in China and Southeast Asia today, costing 2,999 yuan ($470).
