Well it looks like the World's first dual core smartphone, the LG Optimus 2X, isn't without it problems. Regardless of the typical small tedious issues anyone may have, it seems that it is something well beyond software problems. A lot of users over at XDA-Developers have made numerous threads about blank, unresponsive screens, random reboots and very hot temperatures when the phone is recharging. Now since all these problems are so rampant, Optimus 2X owners have gone to file an online petition to hopefully get a response from LG.
Update: Trustedreviews has got in touch with LG, and they have put out the following statement about the Optimus 2X issues.
"a few Optimus 2x customers are occasionally experiencing random device shut-offs. While this does not affect every customer, LG regrets the inconvenience this has caused."
Along with that LG has also said they have found the root of the problem, and they have released a software update here.
If your phone has experienced these problems go and download the update to restore your phone to its former glory.
