Photography is handled by a dual rear camera setup featuring a 50MP main sensor and a 2MP depth sensor, along with a 16MP front camera. The main pros are its impressive battery life, rapid charging speed, smooth 120Hz OLED display, and ample RAM and storage capacity. Potential cons include the use of UFS 2.2 storage (which is slower than UFS 3.0+), the lack of an ultra-wide camera lens, no 4K video recording support, the absence of NFC for contactless payments, and a hybrid SIM slot that requires sacrificing the second SIM for microSDXC storage expansion.
