#1, the pentile screen in the photon is different from other motorola qHD screen's, even engadgets review gave the screen praises & said it was second only to super amoled plus! but imo, i like it more than the amoled plus because the color accuracy is better & compared to the LG nova screen 700 nits of brightness the qHD on the photon is also 700 nits brightness so outside no matter how sunny youll see your screen with color & they have 2 layers of some kind of anti glare with gorilla glass. also the screen is bezeled at the edges kind of like the htc sensation.the blacks are as black as the my ex galaxy s *vibrant*.
#2, the phone has 2 microphones in the back besides the main microphone in the front, when you take the back cover off there are rubber tubes that keep the sound between the holes & the mic's, i guess its for better sound & it seems to work based on reviews of sound quality when recording vid's.
#3, the call quality along with the sound quality is the best ive had since my last motorola phone *nextel* they were always good at reception. i can get full bars where i wouldnt get a single bar, im comparing this to my older sprint phone's & t-mobile. im going to even say verizon because the last phone i had was the evo 3D *returned for photon* the evo 3D would lose reception then switch to roaming & sprint uses verizons 800mhz channel for roaming which has better penetration than verizons other channels. so basically in some areas like inside my building *third floor,concrete walls* i wouldnt even get roaming to work so i would have to go outside to use my cell, but now i get FULL BARS! thats crazy, anyway now i can talk even in the basement of my building & i dont roam so the reception is really really good. try sprints 30 day guarantee theres nothing to lose.
4#, good,clear & its not monotone. the volume is loud so even in busy areas, like i said in manhattans busy streets you can talk & hear the other end without having to raise the volume past 50%, today i was talking to my brother & had to lower the volume because it was tickling inside my ear.
5# the front camer is only VGA (640x480) but its perfect for video chats & the camera is good. the colors are good, the pictures & videos are clear with sharp edges. remember that the mp's dont matter unless the sensors are good. i can compare it to my ex evo 3D which was 1.3mp's & this camera looks better quality wise & i cant tell the difference in pixels, its definitely better in colors, but sucks in low light as did the evo 3D's front cam in low light also.
all this might sound to good to be true but check the reviews or go to a bestbuy or sprint store or even take it home for the 30 days,you wont regret it. heres a bonus my quadrant score is 2900 to 3100 & thats real good for a qHD. considering that the SGS2 gets a 3200 @ 1.2 ghz average with a 800x480 screen & when overclocked gets around 3600, which gets beaten by the galaxy R @ only 1 ghz! tegra 2 is still strong i couldnt believe it scored 3600 @ 1 ghz with no overclocking. * look for youtube videos & see the benchmarks *
