Hello @marcanpilami
Je rencontre encore un souci lors de la numérisation de codes à barres sur les Xcover 4S. Parfois, la caméra se bloque et je ne parviens pas à lire les codes à barres.
Voici la situation : lors de la numérisation, il arrive que la caméra se bloque et ne réponde plus. Cela se produit de manière aléatoire et je ne parviens pas à lire les codes à barres dans ces cas-là.
J'ai observé que l'erreur suivante est souvent présente dans les logs lors de ce blocage :
