Yeah i think the light leakage is a very common problem. Probably the most common gripe about the phone other than the gps. All of mine except one had light leaking from the bottom. The hd video is not too bad on the phone but does not appear to be nearly the quality of most phones with that ability.
Why my Triumph is going back:
(1) Screen has brightness variations that are annoying when scrolling black text on white background.
(2) Screen has very serious image stability issues when scrolling white text on black background.
(3) Screen touch sensitivity issues -- often requires three touches to register.
(4) Screen colors are washed out and inaccurate compared to Nexus One (CM7).
(5) Wifi handling is broken. Many more APs are picked up than by Nexus One, but powerful ones (feet away, direct line of sight) are reported to have medium signal strength far below actual. (Side-by-side experimentation with Nexus One and Wifi Analyzer.) Actual download rate is about 60% of the Nexus One.
(6) Ring tone (at least the one I want) rings only once.
I don't know how the thing performs as a phone or camera. Actually, I don't use phones or cameras very much. But the issues I've found already are easily sufficient to force returning the Triumph. Since most of the problems indicate poor design, poor components and/or poor assembly and definitely awful QC, I'm not considering swapping for another unit.
I think these 2 latest posts sum up the majority of dislikes, without the more limited/lest reported problems. And their lies the crux of the Triumph. Many said this is the 1st mid-high level smartphone on a pre-pay plan.
I wanted to get the Triumph just bc if it was good, and sold well, it would be a starting point, a signal to all pre-pay plans on the big names and smaller carriers that people are willing to pay up front to get a decent level of performance.
I have not been able to try the Triumph, have not seen it as demo unit. But after getting the LG OV, and then trying even lesser Motorola 4+ " screens in BB, I really wanted to get the Triumph for the larger real estate as it's nearly impossible to type on the microscopic virtual keys in landscape/horizontal orientation on the OV, and while the screen might be brighter and sharper...many times I can't pinch & zoom elements and I don't have 20/20 vision such that it is *impossible* read the microscopic text (maybe an AP that resizes to larger fonts, but the screen is so small, that's going to be trouble).
I went into a Spring store to pay off my last contract bill, and tried to call Sprint CS (they were closed for the day) on one of the demo 4G HTC larger screen units, 4.3"? EVO 3G HD iirc, man it's like night and day compared to the OV. The HTC's you only need to swipe down to unlock, maybe 1/2", whereas as both Moto & LG, swiping across the whole screen to unlock sometimes fails and then I miss a call that goes far too quickly to voice mail...rarely had such a problem with my old non-SM unit. The EVO models 3G or 4G are so much faster, more responsive than the OV, it's not even funny. And in landscape orientation I can actually type without 90% error rate, more like only 25%, or pretty good with the Andriod 'swipe' style of entry.
I only can hope with Google buying Moto, that maybe we'll get a newer replacement for the Triumph on VM...ASAP! Not likely though

. If something comes out in the next 6mo, at least with BB, I can get 50% of the price I paid for the OV, applied to whatever newer model...and LG? comes out.
Logic for why we'll never get upper tier models on lower priced PP plans, was on some blog I can't find the link for now. Man, that HTC Ruby, w/quad core 1.5Ghz should be insane...trickle down, on VM we might see something like that in 3-5yrs
I wanted to use the Triumph for Skype video chat

, maybe next year, suppose 4G network is required for smooth vid if it's going across continents. Was so wishing for that capability!
