This seems to be an isolated issue with no viable cause. The message box reads”Unfortunately, the process com.android.phone has stopped” and is disrupting other functions.
Clear Cache and Data of the Phone App Go to Settings, select Apps. Tap the All tab so that all the apps of your device will be displayed in a column. Scroll down until you see “Phone” or an option similar to it. Tap it, followed by selecting the “Clear Cache” option. If the problem persists, repeat the steps and include “Clear Data” in your actions. Reboot your phone for the changes to take effect.
