During the 1923 Corfu incident with Greece, the Italian Navy, including "Andrea Doria", was deployed to occupy the island of Corfu following the murder of Enrico Tellini and four others. Following the peaceful resolution of the incident, "Andrea Doria" visited Spain. On 16 January 1925, "Andrea Doria" visited Lisbon to participate in the 400th anniversary of the death of Vasco de Gama. She thereafter went to La Spezia for a refit, which began on 7 February and was completed by June. Following civil unrest in Syria, "Andrea Doria" steamed to the eastern Mediterranean with a squadron of destroyers in the event that Italian nationals would need to be evacuated. The ships remained docked in Leros until 12 December, by which time the disturbances in Syria had been calmed down. She spent the next six years on normal peacetime duties, until she was withdrawn from service in August 1932. She was placed in reserve in Taranto, with a skeleton crew for maintenance. In March 1937, she started the major reconstruction in Trieste, where she arrived on the 30th. The refit began on 8 April at the Cantieri Riuniti dell'Adriatico shipyard.
