Samsung Epic 4G : Remember The Keyboard Issue ?

I've started a few threads here n other places about the physical keyboard issue. many other ppl have to came forward having the exact issue where it does not recognize inputs. as noted, in some apps this is worse then others. stock browser I have this issue frequently so I dl xscope and at first all was ok then after decent amount of browsing issue would happen more frequent. stock sms the issue happens a lot so I try handcent and at first all was amazing then it would happen a lot again . . tried chomp and same deal. if I hard reset my phone the kb works good on most apps for a lil, then issue occurs again. does anyone who is advanced in diagnostics on these devices think this may be an angle at looking at the issue for a fix ? and if so could a custom ROM be a way at avoiding this issue ? I've never flashed a device on winmo or android but extremely love this device to the point where I would to regain a normal keyboard .. anyone have insight here ?
