I've had these problems from day one I got this phone and I received on the first shipping.
The One UI will just stop working and a pop says, Quit App or Wait. Sometimes when that happens the phone will just freeze and I can't do anything. I have press and hold the power button till it restarts. When making a post it will out if the blue will start typing what my show is saying. At least once screen icons were rearranged. Problems with the Bluetooth and phone. When I make a call it will not let me change to the loud speaker, S7 watch, or my Bluetooth hearing a!des. Without restarting the phone. Then when it's connected to my car. I can't call a person cause it lost it till I restart Bluetooth then it's fine.
Wipe Cache Partition. Turn off phone. While powered down, press power key and volume up button simultaneously until the phone vibrates. Let go of buttons. You will now be in the bootloader. Using Volume buttons for scrolling, power button for Yes. Scroll down to Wipe Cache Partition. Press power, scroll to Yes, press power. Reboot press power key.
