The OnePlus One was released in 2014. The phone came with a 5.5-inch FHD display having 16:9 SIB and 1080P resolution. Corning Gorilla Glass 3 was protecting the screen. Originally, the OnePlus One ran on the CyanogenMod 13 themed by OxygenOS 2.1.3. Back in the day, OnePlus was using the CyanogenMod ROMs on its phones which was also the reason to make the devices quite popular. The OnePlus One was powered by Qualcomm Snapdragon 801 CPU accompanied by Adreno 330 GPU. The phone came with either 16GB storage + 3GB RAM or 64GB storage + 3GB RAM. This phone had a 13MP camera at the back and a 5MP on the front. It had a 3,100 mAh battery under the hood. OnePlus made waves in the smartphone industry with its very first phone. It was the cheapest phone with those mighty specifications back in 2014. The company hasn’t broken its trend yet. It still offers powerful devices under a good price tag.
