If you head over to the (Sony Ericsson support forum), you will see that there are a fair few disgruntled customers to say the least.

Pleased to hear your enjoying your Arc anyway.

 

Well yes, this forum does seem rather quiet which I find a bit surprising. I was hoping for a lot more activity, with people giving there experiences of the Arc good or bad.

 

Yeah it's pretty dead in here. Most of the arc related forum activity seems to be going on over at the xda developers forums. Unfortunately i would have to recommend heading over there if you want to keep track of what's going on.

There are people unhappy with the arc, those tend to fall into one of 2 groups:

(1) People with duff hardware. Seems like quality control isnt all it could be on this phone, so if youre one of the unlucky people who got one that reboots all the time, recommend taking it back & getting a replacement.

(2) People who are bitching that it doesnt have dual core, and is thus somehow already obsolete, despite being repeatedly unable to describe how exactly the second core would benefit them. "Its just, you know, two is more than one". There is no helping these people.

 

i like this phone much, but my battery cant stand a full day, i m heavily on it, playing games,surfing etc. so i m carrying my charger at school... and having a lil problems with wlan, when i m downloading something,or playing on youtube, phone gets disconnected from wlan... i saw some issues about it... but i like it anyway...
and asphalt 6... playing with no laggs...

anyway dual core power at lg optimus 2x is NOT unleashed cause i have read that it android 2.2 which is default on it, doesnt support dual core, so its working on 1?

 

Unfortunately I have bought one of the faulty Arcs that you hear people complaining about. Force closes, screen freezes and sometime the touchscreen doesn't work at all. Obviously it's still covered by warranty but that means it needs to be sent away for repair/replacement.
Like the original post, I was trying to decide whether to go for the Arc or the S2. Love the look of the arc however wishing now I'd gone for the other option.
