[LG Optimus 2x] spawndk:
I bought 2 LG Optimus 2X - one had many problems with reboots and lockups, this one I have now replaced with an SGS II

So currently I have the O2x and the SGS II (my son uses the O2x)

No doubt the SGS II is wastly superior to the O2x - stock rom just works so beautifully, partly because of more ram and a newer Android version, partly because of less bugs than the O2x. The camera is much better on the SGS II for still photography and alot faster to use to, but videorecording I find is better on the O2x (mainly better sound quality).

Construction wise the SGS II is not crap at all, just because its lighter doesnt make it crap. The construction build are actually very good, theres no squicking or anything and its very sturdy despite being so light. I had my fears regarding the SGS II feeling to plasticy but it doesnt. The thin backplate are very flexible and almost unbreakable.

The big screen is nice, quality of screen is very good, allthough the O2x screen have better whites. Touchresponse of the SGS II are better than the O2x. Battery last longer in the SGS II, I almost get 3 days of average use, where i get 1½-2 days max on the O2x. Music and video are a joy to play. And theres no sign of any lag anywhere. Not like on the O2x where it lags when you install from market for instanse.

I still like the O2x, it got nice design, feels like quality, hardware is good, the LG software changes are not too intrusive to basic android, but it simply just doesnt perform the way it should. LG messed up with this.

To many problems with the reebooting and lockups still being experienced by so many people even after almost 6 months since release. And even when it doesnt reboot or lockup its still running a flawed Android Froyo 2.2 which lags in situations where it shouldent (being a powerfull dualcore phone etc.) - you just dont feel like theres any headroom, like you do on the SGS II where the feeling is more like "nothing can slow down this phone". Just feels completely snappy all the time no matter what you do.

I have a friend who just bought an O2x 2 weeks ago, and he is now also experiencing the random reboots and lockups, despite being on latest stock firmware and the phone being completely new (so not some early batch).

Sure you can install custom roms, most have issues of their own and most dont really make the phone that more stable or that more fast or fluent/smooth in daily operations (I dont care what various test software scores are, its real life performance that count) - besides one should never have to install custom rom's to make a phone usable, this is the manufacturers responsibility. Sure you can install custom rom if you want to play around, but it shouldent have to be a nescessity or something being recommended to "fix the phone functionality". You buy a phone, it should work out of the box, period.

All in all I cant really recommend the O2x anymore, sadly. To much of a risk of getting a phone that wont make you satisfied because of the various issues.

It may change when gingerbread are released, but seing what LG has done sofar during 6 months for this phone doesnt leave me impressed or expecting any wonders from their gingerbread
