A50 August Update

Probably next month.
May be this month. They have been testing an feature update since last month and haven't released it.
If you are updating using OTA try next update with Smart swith using pc.
Updating via ota might bring problems if the network is not consistent.

is the restart issue is frequently for you?

Yes you update phone via smart switch or reinstall software to serivice center

As the other guy said, for the next OTA update, don't update via OTA. Try installing via smart switch.
