[LG Optimus 3D] IFLPI:
Edit: there is a comparison in the beginning if you are interested in these two phones.

*** the comparison:

The screen is better on the lg. It has more vibrant and saturated colors. High contrast, it looks very nice. The first time i got the phone i thought LG made lcd screen with colors of the amoled (beside the black that is typically lcd-like, but also deep and nice). Lg sometimes has bug with touchscreen, like some voltage issues or digitizer.

Red blue and green, also white color is very good. Viewing angels are also very wide. Its probably good ips lcd screen, lg make very good ones. Only htc one x can beat it. All sony ericssons with bravia are much worse that this. Only samoled+ can be better, or newest ips slcd2, or whatever one x has.

Htc evo 3d has a bit more natural colors, and white is a bit green, or even greyish but not so much really. But lg is nicer. Viewing angels also a bit worse. I've read that it's a hitachi screen with sony bravia engine. When you move the angle the colors starts to fade a bit. Lg is better. But the digitizer is more sensitive, hopefully without bugs on htc.

3d effect is the same for me, both very good. But evo has more natural colors, not so vibrant (a disadvantage when you are used to lg) but has bigger resolution so that it can be an advantage, little less pixels (but are also visible)

Music: dunno really, at first htc i didn't like the sounds, but now it's quite ok, thou it's different than lg. Hard to tell really which is better, thou at first lg seemed to be better player. After evo's ics upgrade i think evo plays better but it can be a placebo (i installed the leak of ics - almost final, very good, speed is nice)

Camera: i like them both, htc is worse in dark, more noise i think, but camera soft is brilliant, touch to focus and many effects on ics. Video worse than lg imho, and no fHD in standard ROM (but it's possible due to a modded camera)

Soft on evo is fluid on ics, on ginger there is slight tearing here and there, but can be used to. No lags in system, like in lg, that sometimes system stopped, or during a game was thinking suddenly for few minutes. But games on ginger was tearing badly (soft issues) Ppl say on ics it's ok. Benchmarks seem to show almost the same efficiency as lg 3d.

Htc Sense is much different, very complex, don't appeal visually to me. I like the simplicity of Android, lg has everything i needed, smart dialing, notification/power widgets with shortcuts to settings (long press) very comfortable. Sense is too complex sometimes. But it has many neat functions, good browser, lockscreen, widgets, apps etc.

If you have questions tell me.

*** The problem : I think I'm used to my lg phone, i like it, even with its faults. This is for sure because of nice developers here. Also the screen is very nice, colors are very vibrant. It's better than all other lcds. The processor is also very good, nice gpu, good for gaming. It lacks the ram thou. Lg is has a terrible support, update will be late and maybe buggy. Buy it's a simple and good phone, with nice hardware. GC fix is on the way...

But now i have htc evo 3d on the new contract with operator. I don't like htc sense, design is strange, screen colors not so vibrant. Games probably worse than omap4. But it has ICS (the leak but official will be very soon) 1gb of ram etc.

I'm tied to this phone (p920) and don't want to sell it. But two is too many for me. I had the same situation with the Milestone. Sometimes it was driving me crazy, but i liked that phone in general. After 1,5 year i sold it but i missed it, especially the qwerty.

It's strange that anybody can be so tied to a phone, it's just a thing. I'm afraid that i will regret if i sell lg. Now there are many good ROMs and games run very well..

I don't like htc very much, but I'm torn apart, cause it's good phone but not that i really wanted (just it was a good offer and i decided that i must take and maybe sell it)

argh... I'm so confused... I sell them both to buy a galaxy nexus maybe ...

Lg is now very fast on custom ROM, evo isn't for me a satisfying upgrade. Evo is also not best for modding, cause on aosp camera don't work (because there are 2 versions on evo, on mine camera won't work in aosp, miui, cm roms, i have older version with 2 5mpix cameras, newer has 5+2mpix camera, custom roms are for newer one)
