Yesterday the new OnePlus 3T smartphone was announced, the handset retails for $80 more than the OnePlus 3, the two handsets are currently available from OnePlus.
Now it would appear that the OnePlus 3 will be discontinued and replaced with the OnePlus 3T as the company have revealed that once existing stock of the handset is sold out it wont be coming back.
The guys over at Android Central were told by OnePlus that once the existing stock of the OnePlus 3 is sold out in the US and Europe it will not be replaced.
So it looks like the OnePlus 3T will be replacing the OnePlus 3 when the handset has sold out, although you may still be able to get the device for a while from various retailers.
