Review after using for almost 2 months:
1. Performance: SD855 doesn't need any explanation about performance, especially when it is clubbed with 8gb Ram and 256gb UFS 3.0 storage. It's an absolute stunner. You will never feel any lag even if you open several apps. I play a lot of games and that too in fully loaded graphic options. Its a charm to use graphic intense gaming on this device. Throw anything from the play store as on date, it will perform amazingly.
2. Battery: Its decent, not too much like my other device (Asus Max pro M1) but its good. Most important is the dash charger which refills is super quickly. But wished the battery would have been great if it was 5000 mAh.
3. Display: Super Amoled display is one of the best displays in market and its performance is top notch. Both sides protected by gorilla glass is added advantage.
4. Camera: This is where it disappoints me. I have been using samsung devices from past 3 years, and S7 from past 2 years. I feel S7's camera is much more accurate. Pictures of OP7 are very much saturated and i also really miss the SloMo of Samsung.
SloMo of OP7 is also disappointing. Many people have suggested to go for GCam, but it never worked well. It used to hang a lot, so i removed it. Although pictures are good but i feel that way just because i am obsessed with S7's picture quality.
5. Removal of headphone jack is utter nonsense. Although i have Samsung level u Bluetooth device but still the headphone jack is missed.
6. OxygenOS is super snappy and cool. You get instant security patches every month.
Overall, i am pretty much happy with the device and would surely recommend anyone who is a gamer and want to enjoy the beast under 38k.
Cheers!
