Hi I have Xperia X Performance but I've noticed that it's using about 94% of its ram on only idle, I reckon its because of bloatware on it by docomo and xperia but I want someone to suggest to me that if I'm willing to root and uninstall these trash bloatware which ones should I uninstall since there could be an app that if I delete and its important then it'll screw up everything so I want you guys to give me some tips on which apps to not delete or some other tips on making the ram usage normal
