I have purchased Samsung note 03 years back, the phone is quiet good in the beginning. large screen. good battery life, good camera quality, music quality. But as the time passes by it started becoming super slow & now it take tooo much time to open a contact or app. Further the system storage is almost full & I am unable to update anything though I have moved most of the apps to the sd card but still I wonder what is using my storage space. There are few inbuilt apps which are totally useless.
