Some HTC handsets go 16 bit after Windows Phone NoDo update
Share:
Updating your Windows Phone 7 handset is supposed to improve the functionality of your phone, but it seems that recent updates have done everything but that. Some Samsung handsets were bricked after a minor update and now WP7 NoDo update has brought color depth problems to HTC phones. Luckily, this time the issue doesn't render your phone completely useless, but decreases image quality to 16 bits.
“I've got NoDo on HTC Trophy. Everything is okay at the moment, except a color depth. It was definitely decreased from 24bit to 16bit. I see now bandings on wallpapers and pictures. It was not like that before - the gradients were smooth and nice. Why it was changed and how I can 24 bit back?”
An unofficial fix has already been posted on the XDA Developers forum. You have to change the following keys in the registry, followed by a reboot, but try it at your own risk as Microsoft hasn't come up with an official statement just yet:
HKLM\Drivers\Display\Primary\PrimBPP dword 32
HKLM\Drivers\Display\Primary\bpp dword 32
HKLM\Drivers\Display\Primary\PanelBPP dword 32

Welcome to the world of tommorrow.......or maybe yesterday with 16bit systems. windows phones are a disaster,every update runs the heavy risk your phone will be bricked or suffer something like this. For an os with a terrible ui of ugly block panels and massive os limitations they really aren't helping themselves with big mistakes like this

Mr Andro(id), you suck. You saw a chance to spill some hate and you took it, right? No need to listen to what you say because you only say it in a bitter state of anger, true?
At least the update is pushed through to all devices at the same time (if it wasn't for your US carriers cockblocking their customers). How are those Androids updates going? Many 2.3 handsets out on the market yet..?
