My Note 2 has strange slow down after hours of use. After hours of usage
system_server and maybe
kworker use a lot of CPU, mostly during apps open and switch, it lags badly. I also have around 200 user apps installed, and mostly greenified, so I expected that my device shouldn't be slowed down like this even with a lot of apps installed. I used to experience
kworker using a lot of CPU on Tab 7.7, but less than 30 user apps installed. Even safe mode, changing ROMs doesn't fix the problem; finally wiping both
/data and internal SD fixed the problem. It is now fast.
So I would like to try running various user apps on safe mode, to see if it still slow down after hours of usage. Or I have to wipe both
/data and internal SD to fix the slow-down problem like I did in Tab 7.7. I have a lot of data and apps in the internal SD, free space is 1.5 gb/10 gb. I feel lazy to backup and restore (it's a lot of data) and try the fix of wiping data, so I would like to try running a lot of user app in safe mode first. There are some exploits in TouchWiz ROM which allow that:
I'm using this 4.4.2 firmware. On this firmware, I can do it partially. By adding apps to lock-screen shortcut. Those apps can be opened in safe mode. In DN3 Rom before Kitkat update, user apps added to Samsung Note 3 Touchwiz Launcher home screen can also be opened, but not anymore in Kitkat update.
When I installed custom ROMs on Note 2, I never wiped internal SD, I wiped only
/data partition, an this probably is the cause of lagginess in Tab 7.7.
So is there any more ways to open user apps in safemode?
