I am using oppo A58 and there was a system update last night but unable to make phone calls after the update. The screen shows calling but nothing happens after that. Mobile data is working. Please advise.
Thank you for replying. 4G mobile data is working but does not place any calls and it shows calling and nothing after that. Should I wait for some time if it's a public mobile might fix it or better start looking for a different phone.
