Very recently my phone has been locking up way more than usual. I recently received a network update and have been getting 3G service for the first time since I purchased the phone. I'm operating off of the Metro PCS service and have rooted my phone with the LG Opt.M one touch service. Does anyone know of a reason for these lockups or know of an error checking service that can diagnose the issue for correction? For clarification, it locks up fairly randomly. I can be checking my email, surfing the web, texting or playing a game. I don't have any constant services running (unless I just started them) and I've been using the Android Optimization Toolbox and Advanced Task Killer to keep my ram and cpu usage down.
