Re: "The process android.process.acore has stopped unexpectedly. Please try again" help please ??
I have a LGL55C, but had the same problem at the same time. As it turns out, my contacts are sync'd with the phone through Hotmail, and Hotmail has been taken over by Outlook Express. Outlook Express made the Hotmail app that syncs the contacts stop working, and required customers to replace the app with the Outlook Express mail app. Because they did that to everyone who uses Hotmail with their smart phone at the same time (apparently), whenever I tried to install the Outlook Express app, the installation failed. Several days later, I was able to install Outlook Express, sync my Hotmail contacts to my phone through Outlook and uninstall the Hotmail app. Now everything is working, all my contacts are available and I don't get the error message. I think any similar situation, regardless of the type of phone or which email you use, may cause the same error message. In that case, the phone just isn't connecting to whatever email your contacts are stored through.
