My Xperia SO-01E was running slowly, so I deleted and disabled unnecessary apps.

There were many preinstalled apps from Docomo and Sony, so just deleting and disabling these apps made the performance comfortable.

Below is a list of the apps I deleted and disabled.

I was considering replacing this Android device I purchased two years ago, but with just maintenance like deleting and disabling unnecessary apps, it became usable again.

If you’re having trouble with slow Android phone performance, it might be good to organize the apps that were installed from the beginning.

Reference Information

• [Z] List of services that can be deleted/disabled without root (Docomo proprietary services, etc.)
• Disabling unnecessary preinstalled apps on Android smartphones - Woresite
• WM×LI: SO-03D (Xperia Acro HD) Disabled App List

That’s all from the Gemba.
