* TOP Battery Endurance* TOP Screen* TOP Software* TOP Camera
EDITORIAL: Less then a year after GT 7 here comes a proper upgrade that may signal a shift in Realme's (and it's parent Oppo's) expectations. This is a true flagship phone with a slow USB-C 2.0 port as it's only real weakness. GT 8 Pro is shorter and thinner then it's precessor while bringing a bigger 144Hz hi-res Dolby Vision screen, top performance chip and memory, very long battery endurance and a strong Ricoh tech imaging package that includes a 200MP periscope telephoto. To razzle dazzle, Realme created a removable camera module cover that can be replaced with custom covers of different materials, shapes and colors making this a truly unique offering for a fraction of the price your will pay elsewhere. You should consider buying this big phone if you can find it in your market.
PROs
customizable camera cover system - a true first on the market, fast SD 8 Elite Gen 5 with UFS 4.1 performance, 48hr endurance from a 7000mAh Si-C anode battery with sub-60min 120W (50W wireless) charging. >1900nits bright >500ppi 144Hz LTPO AMOLED with Dolby Vision, IP69 protection. excellent imaging from a 50MP 24mm main + 200MP 65mm 3x periscope telephoto (both with OIS PDAF) + 50MP 16mm fixed-focus ultrawide, up to 4 years of OS updates and very good stereo speaker setup
CONs
almost 79mm wide and hard to use one-hand, scratch and drop resistance may not be flagship-like, no AF on 24mm ultrawide, mediocre 32MP non-AF selfie, mediocre video recording, no expandable memory not video-out or desktop replacement functionality, can get very hot under prolonged heavy load

FLY* TOP Screen* TOP Camera* TOP Video Recording
EDITORIAL: This year, one of the TOP 5 camera phones came with a significant battery endurance improvement. The main camera retained the 1" sensor, lost the variable aperture but the 2 zoom cameras are now better then ever. There is no AF on the selfie and like last year, there is an extra camera grip available for the ultimate photo & video creation. Still missing are SD memory card and the desktop replacement feature. Promised are 4 years of OS updates.
