It would appear that OnePlus will be releasing an upgraded version of the OnePlus 5 and if you guessed that it will be called 5T you are correct. There are already leaks of what the phone will look like but now the entire hardware specifications is already on AnTuTu for the world to see
Based on the leaked screenshot of AnTuTu results, the upgraded phone seems to have an 18:9 FHD+ display but will still be powered by the Snapdragon 835 chip and the same Adreno 540 GPU. It will come with 8GB of RAM, 128GB of storage which for the first time is expandable, the rear camera will now have a pair of 20MP sensors and the front camera is also 20MP.
Based on the leaked images of the phone, it safe to assume that the fingerprint sensor will be pushed to the back of the phone to accommodate the full body display but it will come with Android 8.0 out-of-the-box. We are expected to hear some official news of the OnePlus 5T in the coming weeks.
