hi i had the HTC m8 but sold it recently, yes the camera is not very good in low light, display is not as vivid and vibrant like the s5, but i tell you ,its a sexy phone, nice curves and it has a solid feel to because of the stainless steel body, it actually feels like your holding a phone in your hand, unlike the s5 with plastic feeling. i am use to htc so i just got a second hand htc m7 beacuse it fits perfevtly into my pocket and ideal size for work purposes..ph also its has the boom sound blows the tinny s5 speakers away..
