Note 10 plus became too much sluggish, navigating to home or one to another app need to wait upto 5 seconds before it starts responding. This started happening after few days of factory reset, then it became super fast after recieving One UI4 update and it lasted only few days and again started too much sluggish. Tried different method and finally found when I started in Safe Mode, native apps Gallery, Camera and YouTube is instantly making the device slow, and I am using alternatives now and no more seeing slow until I open these apps. Very weird and disappointed that native apps are creating such slowness and I am forced to use unofficial less featured alternatives, and I don't think samsung will address this as Note 10 is already old for them. I read the same issue in couple of other forums as well, in case any of you face this, can try this method.
I too suspected but it could handle several other heavy apps, even usual fast after 5 seconds of no response, example i will start playing youtube quickly as soon as app open, it will play for 5 seconds, then it will refresh, stop playing and go to home. So i should wait for refresh and should start playing. This is case with every navigation, wait for 5 seconds to refresh again.
It's been long time since and I was afraid to do Facrory Reset again since it introduced major problem last time, but now Factory Reset phone again without restoring any from backup to give a final try and here are results,(Also in safe mode) > Issue still exist! > No new issue observed
My observation: > Phone becomes super fast and no lag on every major updates even immediately after factory factory reset > It becomes sluggish after a day or two and identified it occurs on heavily cahed apps > Clearing cahce instanly rssolving issue
Conclusion: > Cache memory became weak or damaged during 1st time Factory Resetting phone
Not sure I am the only unlucky one in this case here.
WARNING: > Think twice before Factory Resetting, it may damage cache memory as I experienced!
