Hello. I recently updated my android software per my carriers message of update availability. Now my phone often slows down. After running CPU monitor, I find that the biggest usage is done by kswapd0 and system_server. Majority of my apps are on SD card. I have about 20% free internal storage and 20% free RAM on average. Anyone knows what may be a problem and how to fix it? Below is some data. 

 

 

Phone Samsung Galaxy S5 with 32Gig SD card. Android version 5.1.1 Provider is T-Mobile.

 

 

 

Any suggestion is welcome. 

 

 

Thank you.

Since most of your apps are on your SD card that's going to make that core Android kswapd0 function work overtime.

Take a look here for more information: https://creieras.wordpress.com/2011/12/16/how-to-android-kswapd0-problem-solved-igo-myway-lag-fix-too/

This is the key element of whats going on:

Kswapd0 is a core Linux(and therefore Android) process, that does it’s job by moving data from the RAM to the SWAP partition on the SD card when the RAM is getting filled(that is slow as a snail compared to the RAM).


I would suggest moving your high usage apps to main memory. This may help your issue.

Good morning. I installed Semaphore Manager. It won't let me run it without another app. But it presence seems to be keeping my phone running well. When I uninstall it, phone began to slow down over time. So I reinstalled it again. I will keep you posted if anything changes.

Thank you.

There is no reason for my phone to be slow. It always has at least 300 megs free ram and 2 gig free of internal storage. Not many apps running in the background, and I got rid of live wallpaper. This happened after recent uodate. My friend has iPhone and it became slow as well.
