vish1191 , via OnePlus 5T , Oct 23, 2019 : I am currently using oneplus 5t and my phone is facing issue of application refreshing while multitasking in the background and the phone is not able to keep the apps in memory not even two or three running in background. I am currently on Oxygen OS 9.0.9 the latest update. this issue has been persisting sense Android 9 update and it is not helpful at all. even budget phones from realme or redmi perform better these days in ram management as compared to to my phone or even for the sake oneplus 6 ,6t,7,7t. any suggestion which this problem can be solved. I have already tried changing battery optimisation options so give any other solution if available.
