Nokia n73

[modeus]

Отже, маю такий телефон. Є в ньому картка пам'яті. Підключаю через USB. Проблема в тому, що чомусь нормально підключається він десь із 5-10 разу (методом витягування й тикання кабелю в USB). Власне це не критично - можна й потикати. Але цікаво чому так.

Проблема виявилася вкрай банальною - забруднені контакти на телефонному роз'ємі.
Почистив і профіт. Все працює.
