Technologies live among us and change our world; people can watch footage of Mars on TV and order lunch on phone during the pandemic.

This passage only provides some common ideas for at-home device checking. If you have any questions, do not hesitate to open the thread or reply others' thread in the community.
If the issue appears right after any apps' download or update... Please try to enter "Safe Mode". If the function works well in Safe Mode yet the issue remains out of Safe Mode, please check any disturbance from installed 3rd party apps.
Internet or signal related issue 1. Check Settings>Network & internet>Mobile network>Preferred network type 2. Check the APN setting of your area with the local carriers 3. Settings>System>Reset options>Reset Wi-Fi, mobile & Bluetooth
Is performing Factory Reset necessary? There is no harm in checking some other ways first. (1) Safe Mode (2) Check the Storage (3) Check Settings>Apps & notifications>See all apps>3 dots on the top row>Reset app preferences Still, performing the Factory Reset is a quick way to erase disturbances from the installed 3rd party apps. Settings>System>Reset options>Erase all data(factory reset) *Please note that once the Factory Reset is completed, all data, apps, settings and personal information will be deleted.
