At first glance, the phones appear quite similar but around the back the X27 Pro's triple camera is aligned centrally. It has the same 48MP main and 13MP ultrawide sensor as the X27, but the depth sensor has been downgraded from 5MP to and 2MP.
A more crucial difference is the elevating front camera which now comes with a 32MP module with flash compared to the flash-less 16MP one on the standard X27.
The rest of the spec sheet matches the X27 with a 6.7" Super AMOLED FHD+ screen, Snapdragon 710 with 8GB RAM and 256GB storage.
Pricing is CNY 3,998 ($595/€530), a small premium over the standard X27’s CNY 3,600 price tag. Official sales are scheduled to begin on April 18.
