How to turn off HD for oppo mobile phones

Code Off If the user searches all the options in the mobile phone and finds that there is no HD off option in the mobile phone system, he can open the dialing interface of the mobile phone and enter the code "* # * # 86583 # * *". It should be noted that the double quotation marks on both sides are not counted, and the Chinese is "Xingjing Xingjing 86583 Jingxing". The code demonstrated in this article lacks the "asterisk (*)" symbol, and the interface will automatically jump after the input is completed. However, based on the difference of mobile phones, some mobile phones will not jump, but will be turned off directly by default. Take IQOO mobile phone as an example, just turn off all the options in the interface after jumping. In addition, if the user wants to turn on this function again, just enter this code repeatedly. Customer service phone If the user thinks it is troublesome to turn off the code, and the code may not work based on different mobile phone brands, then at this time, he can call the customer service phone of the service provider to which the mobile phone number belongs, and take Unicom customer service as an example to directly call the customer service phone for help.
