@Omar Longa: Is the issue occurring while you're using a particular app or feature, or is it random? Can you try restarting the phone in Safe Mode and monitor the performance for a few hours, depending on the frequency of the error. If you notice an improvement, restart the phone as you would normally and delete any recently installed third party apps.
To enter Safe Mode, press and hold the Power button until the 'Power off' prompt appears on the screen then release > Touch and hold Power off until the 'Safe mode' prompt appears then release > To confirm, tap Safe mode > With Safe Mode enabled, ensure Airplane Mode is turned off.
