Sorry for this wall of text. Kindly provide some insights on this issue.

This happen at november. Updated samsung device care from galaxy store and it happen. Tried downgrade to an older version from playstore but didnt solve it.

Next is, the firmware update with october security is released. So i just format phone, updated the phone and reinstall all my apps. But the high cpu usage causing phone lag is still there.

Next, i narrow it down to this app, internet speed meter (an app which shows real time data upload/download speed in status bar) which is causing the phone lag. After uninstall it, its better but still with occasional lag. This is weird as the app was not updated at all, so theres no changes in the app. And it was working flawlessly before november.

Next, i tried others apps which provide the same function as internet speed meter but the result is the same. When the app runs, the phone will lag. Once forced stopped, the phone will not lag as much.

Was wondering if theres any changes to samsung device or the firmware OS which result in this lag.

A little description on the lag. When those internet speed meter is running, even opening other apps like xda, it will take about 10 seconds to open. When using samsung internet, when open app and opening new tab or just click on settings or any part of the app, it takes 5 seconds to load/display.
Currently, without any internet speed meter app, its takes about 1 second to load. But, it cant reach the speed before november. Before november, everything loads real fast even when running a few apps at the same time with internet speed meter running.

Anyone who might know what went wrong kindly enlighten me on this issue. Thank you.

Something to add on. If using samsung internet explorer to download files, the download speed will be slower and somehow the phone will lag. If i use dolphin browser to download the same file from the same server, there will be only a very slight lag but the download is fast. Anyone knows what might be the problem? Thanks.

Try disable bixby & google assistant or force stop them, uninstall google play services updates from app info, disable sending diagnostics data & automatic update.
Bixby and google assistant are off. Diagnostic report and automatic updates are off.

Will google play service lag the phone that much?
