+       It's correct if there is only the owner user and only one app is removed.
+       Problem 1:
+       If there is a user profile, the size of mAppEntries < mApplications is normal because
+       the number of app entries on UI (mAppEntries) should be equal to the number of apps got
+       from PMS (mApplications).
+
+       owner only case:
+       mApplications: user 0: 191
+       mAppEntries  : user 0: 191
+       total mAppEntries: 191, mApplications: 191
+       If an app is removed, cached mAppEntries: 191 , mApplications: 191 -> 190, it is detected
+       as the number of apps becomes less.
+
+       If there is a work profile, mAppEntries removes some apps that are not installed for the
+       owner user.
+
+       For example, in the following case, 6 apps are removed from mAppEntries for the owner.
+       mApplications: user 0: 197, user 10: 189 => total 386
+       mAppEntries  : user 0: 191, user 10: 189 => total 380
+       If an app is removed, cached mAppEntries: 380 , mApplications: 386 -> 385, the size of
+       mAppEntries is still not larger than mApplications, then does not clear mAppEntries.
+
+       Problem 2:
+       If remove an app and add another app outside Settings (e.g. Play Store) and back to
+       Settings, the amount of apps are not changed, it causes the entries keep the removed app.
+
+       Another case, if adding more apps than removing apps (e.g. add 2 apps and remove 1 app),
+       the final number of apps (mApplications) is even increased,
+
+       Therefore, should not only count on number of apps to determine any app is removed.
+       Compare the change of applications instead.
