When I plug in, using the cable provided, my wife's Pixel three, immediately appears as connected and I have no problem transferring photos! Doing the same operation with the Pixel 6, just purchased, PC does not see the smartphone. (Not a direct trans, I revised to make more readible).
ANSWER in terrible French HOPE IT WORKS:
Lorsque vous l'avez branché, y avait-il une notification de chargement de cet appareil via USB? Je pense que le Pixel 3 aurait la même chose. Cependant, je n'ai pas de Pixel 3 ou de Pixel 6. Cependant, dans tous mes téléphones Android passés, cette charge de cet appareil via une notification USB est apparue. Si c'est le cas, vous choisissez « Utiliser USB pour », sélectionnez Transfert de fichiers. Excusez mon Français, je le parle beaucoup mieux....
PRIMARILY WHAT I BELIEVE I SAID IN ENGLISH...
When you plugged it in, was there a Charging this device via USB notification? I would think the Pixel 3 would have the same. However, I do not have a Pixel 3 or a Pixel 6. However in all my past android phones this Charging this device via USB notification appeared.
If it does then you choose "Use USB for," select File Transfer.
Excuse my French, I talk it a heck of a lot better....
SO, THOSE WITH A PIXEL 6 DOES THE USB NOTIFICATION POPUP LIKE IN PREVIOUS PIXELS? I KNOW ANDROID 12 OFFERS THIS NOTIFICATION.
