The effect of deleting these applications depends on what sort of bloatware you are removing from your phone. For example, ChocoEUkor is bloatware designed to help people write in different fonts in the Korean language, and it has nothing to do with any other files, so deleting such app packages won’t affect the phone’s performance. On the other hand, we have bloatware like Android.com.settings which help in the background for apps to achieve their full potential, and such bloatware contains many files which are interrelated and works based on the app code to provide the best user experience. So if you are deleting such apps they might have a drastic impact on the apps and features associated with them. The effects solely depend on what bloatware you want to delete.
