Touch screen not respond
The touch screen works only in the recovery mode
I have done hard reset and still the problem !!?????
If I'm not mistaken you navigate with the volume buttons and the power button in recovery mode so you don't use the touch screen . So the digitizer is not working so as you did not specify which oppo phone you have I canot direct you to a digitizer but you can find them on ebay or amazon . Oppo Phone Repair
This guide page will show screen replacement for 3 different oppo phones . Hope this helps
