I was using a A9 Pro and changed to a C9 Pro last week. Now I am having network issues. I am using a Vodafone SIM for calls and Jio for data. On the A9 Pro I had no network problems. Now with C9 Pro I need to run outside to attend calls. Now I have this dead set which i paid 32 thousand which runs of Android version 6 while my A9 Pro runs of 7. I think it has to do with Android System WebView (uninstall updates and reinstall) and integrated Google app spyware + deep sleep causing issues. Check battery settings, device care which apps are crashing and either uninstall or reinstall. Make sure you have Samsung secure folder uninstalled and Google manually disabled and all data 1. Perform A Force Restart. Press and hold the power button on your phone and reboot to the safe mode. Tap on the Ok button to enter into the safe mode. Wait for the OnePlus 7 Pro phone to restart. [You will see the safe mode symbol at the bottom left corner of the screen] So here we go i have another problem with my c9 pro after oreo update i have fast charging problem and now after 291MB(if i'm not wrong) screen blink countinue now its time to say good bye samsung and welcome to ONE PLUS 6T .. Samsung Thank u Very Much for wrost C9 Pro. Step 2 – Restart the device. When the installation process is frozen, the entire device is frozen. So restarting it at this point is actually a hard-reboot. You will either have to press the reset button, or to forcefully shut it down and then turn it on from the power button to fix the Surface Pro 4 update stuck. Press and hold the Power and Quieter keys to restart the device in bootloader mode. Connects your smartphone to your PC via a USB cable. Opens Windows Explorer and searches for the previously downloaded firmware in the ADB Tool folder. Double-click on the file flash-all .bat and wait until the process is completed. The best working fix is a firmware update. Overheating and lots of other issues are fixed by manufacturers via a firmware update. Therefore I recommend you to check for updates and update your Samsung Galaxy C9 Pro if available. Sometimes, there are multiple firmware updates, and these updates are installed one by one.
