My S9's IP Certification failed😠. The dispaly is not working🤬. Why samsung?? Then what is the need of purchasing flagship over midrangers for this fke certification? What can I do?
Hey we are sorry to hear about your issue.
Since the device display is not working, you can't perform any troubleshooting to fix IP Certification issue. Please connect the charger then press and hold the volume down and power button simultaneously for 7 seconds to restart the phone.
If you can boot up the device normally, go to Settings > Apps > Google Play Services > Storage > Clear cache > Manage storage > Clear all data.
Go to Settings > Apps > Chrome > Storage > Clear cache & data.
Thank you :)
