OnePlus 3 have heating problems while charging the device with Dash Charge. However other than that there is no any heating issues. The battery heating can be solved if you charge the device by turning it off, but I know that’s not a sweet solution.
OnePlus 3 issues or cons is that there is no any microSD card slot. Yes, the 64 GB internal memory is more than enough but having an external memory card slot is a huge benefit for users who usually uses more than two cellphones.
Any VR or Virtual Reality headsets is compatible with the device but the problem is that the display resolution does not stand up like the quality of other flagship devices from major brands. A display with mere 401 pixels is definitely not enough when it has to be help up close to the head.
It comes with a battery capacity of 3000 mAh which is definitely nor enough. It hardly last a day even under normal usage.
