EVO 4G has some minor drawbacks -- its battery life is
rather poor necessitating daily recharges; and it can't make
simultaneous calls and internet requests when outside 4G (WiMAX)
coverage. However, the phone packs a gorgeous 4.3-in. screen
of the best hardware seen in a smartphone, Android or
otherwise.Some owners and developers, however, have noticed
something unusual. The phone appears capped at 30 frames per
second in both 2D (Canvas) and 3D (OpenGL), according to posters at
xda-developers and Google
Code forums. In
the current version of Sense UI and Android 2.1 which are loaded in
the phone, that slower framerate detracts just slightly from how
smooth the animations look, compared to on phones like the HTC Hero,
which gets 54 fps. However, in Froyo -- the upcoming Android
2.2 upgrade -- the drop in frame speed reportedly becomes especially
notable.Android framework engineer "Romain Guy"
isn't quite sure where this problem is coming from. He wrote a
response, saying that for the record the "target was, is and
will be 60fps." Strangely the Nexus One, which
Froyo support already, also seems to be having the issue.
It at least starts out during the Froyo running load animation at 60
fps (which allows it to appear smooth), but its framerate
subsequently drops to 30 fps upon reaching the home screen.The
HTC EVO 4G and Nexus One are two of HTC's most powerful handsets in
terms of RAM, processor, and graphics capabilities. It's more
than likely that this is like a firmware issue and not a hardware
issue, considering the HTC Hero, by contrast, has inferior core
hardware. Hopefully, HTC can get to the bottom of this in a
timely fashion, so Android owners can get back to breaking some
mobile 3D benchmark records on their sleek smartphones.
