OnePlus 4 is on the right track and will launch before the end of July. According to reports, the upcoming OnePlus 4 is expected to ship with a red paint color option in addition to Black and White variants.
According to unconfirmed reports, the OnePlus 4 will not be released in 2017. Instead, the phone will be named as OnePlus 5. The main reason behind the move is due to the fact that the number 4 is not a lucky number in China. Hence, companies are avoiding 4 and shifting to 5. Hence, you can infer that OnePlus 3 will be replaced by OnePlus 5 and not OnePlus 4.
On the optics front, the OnePlus 4 will be equipped with dual camera sensors on the rear with a dual-tone LED flash. You can expect a 16MP sensor on the rear. If the rumor of a dual-camera turns out to be true, then you can expect another 8MP sensor. When it comes to a front-facing shooter, the phone will ship with a 12MP sensor. However, few reports specify that the rear camera will be integrated with a 24MP sensor alongside 8MP front-facing snapper.
Under the hood, the OnePlus 4 will ship with a Snapdragon 835 processor coupled with 6GB/8GB RAM. The handset will be available in both 64GB and 128GB internal storage variants. OnePlus will not provide a facility to expand the storage. However, OnePlus 4 will change this theory and will add the capability to extend the storage using microSD card up to 256GB.
OnePlus 4 will ship with the same 5.5-inch AMOLED display with support for a 2K resolution. We also expect a premium variant of the phone with an OLED display since OnePlus CEO Carl Pei hinted at a possibility of the new display.
The phone will be loaded with OxygenOS on top of Android Nougat. A 4200mAh battery with dash charge support supplies power for the phone. There are reports that the OnePlus 4 will also ship with a 32GB internal storage model.
