For the first incoming call, every day my phone misses atleast first 10 rings of the incoming call and it is extermely slow as well till I reboot. After rebooting it works perfectly fine till the next day
Had been debugging this from past few days and uninstalled quite a number of apps. Still no resolution.

Only observation which looks promising is that multiple processes of "../browserd -n RTComMessagingServer..." consume a total of more than 70% memory. Can somebody please let me know what this process is for, why it consumes so much memory even when the phone is idle and which application launches it?
