we just confirmed that the Samsung i-600 has the same firmware bug than the
Motorola Q, i.e. it sends spurious private messages to the applications.

this firmware bug is documented here:
http://www.modaco.com/Motorola-Q-Spu...a-t242539.html

in the case of the Samsung i-600, the spurious messages are sent when the
phone is flipped open or closed. the message sent to all application is
0x000080ca - which is a value reserved for interthread-communications in
applications and should NEVER be sent to an application unless it expects
this message to be sent.

this can cause applications to randomly crash or misbehave when the Samsung
i-600 is flipped closed or opened.

i think that the Samsung i-600 is also known as the Sprint PCS Vision Smart
Device SP-i600 (as we had other reports of this from people using this
device).

we have received reports that the same firmware bug also affects the Asus
P525.

it is very important that MSFT makes sure that they tests this in their
platform validation tests.

It's pretty common that these devices broadcast messages without
registering them properly. Hopefully the companies that the OEMS are
outsourcing their work to will figure out the right way soon.

So far, HTC, Samsung and Sharp PPC devices for sure do this. Probaly
others. I suspect we're dealing with dev teams who are still a little in
the embedded systems mindset - "the device will always be in the state
it is when we ship it".

however in this case, the messages are sent in a range which is explicitely
reserved for private use by the application.

since the OS (that includes the shell and proprietary drivers) on various
devices (Samsung i-600, Motorola Q, and others) send messages in the private
range normally reserved for the inside use by applications (for inter-thread
communication), it is very difficult for application to determine for sure
what range of messages can be safely used for its own inter-thread
communications.
