No, I whipe nothing after an OTA update. I just let the process to come to the end and then I use the phone.
At this moment, there are still some little bugs like "scan effect when screen is locked" (it tends to appears after a restart), animation when screen is off (it doesn't change), the headset button bug and the music playback hangs (sometime the music player tends to hang when easy multitasking). I forgot also emoji bug, low in call volume when using headset and the impossibility to change the in call volume during a call.
