LOFIC stands for Lateral Overflow Integration Capacitor - it's a capacitor that takes in the charge that goes over the photodiode's full well capacity. This enables things like single-exposure HDR and longer exposures. We've already seen a LOFIC sensor from OmniVision - the OV50K inside the Honor Magic6 Ultimate. But the Ultimates have always been experimental, this is about wider adoption. More recently, OmniVision unveiled the OV50X, a 1" sensor with 8K HDR video.
The 6.3" 1-120Hz LTPO display on the front is similar enough to the previous model - it is brighter at 3,500 nits peak and has slimmer 1.18mm bezels, but the major upgrade this generation is the improved power efficiency. And then there is 2.7" display on the back (904 x 572px) with the same 3,500 nits peak brightness (it even has DC dimming and up to 120Hz refresh rate).
If you're looking for a quick easy answer, it's the Pixel 9a. Released last spring, between the Pixel 9 and 10 generations, the 9a is Google's "entry-level" phonebut it's still got excellent battery life that will last you most days from the moment you get up until bedtime. All the while you'll be looking at an OLED screen and taking stunning pictures with its 48 megapixel camera. Even compared to the most popular alternatives from Nothing and OnePlus, the Pixel 9a undercuts them on price. But there's nothing budget about it.
