She qualified for the vault final but finished eighth with major errors. In the spring of 2015, she won the balance beam titles at two World Cup events (Doha and Varna, Bulgaria). Under pressure to medal in the team event at the Southeast Asian Games in Singapore, she led a minimal team of four gymnasts (full teams consisted of six gymnasts) with Đỗ Thị Vân Anh, Đỗ Thị Thu Huyen and newcomer Long Thị Ngọc Huỳnh. The team was plagued with injuries and finished fourth, but Phan qualified for all of the individual events. She went on to win the most gold medals of any gymnast at the competition (individual all-around, vault and balance beam), as well as a bronze on floor exercise. At the 2015 World Artistic Gymnastics Championships in Glasgow, she finished 85th in the all-around in qualifications with a total score of 51.033: 14.400 on vault (47th), 10.233 on uneven bars (193rd), 13.300 on balance beam (58th) and 13.100 on floor exercise (84th). Because of injuries, she opted not to attempt a second vault to qualify for the vault final. Phan finished 41st in the all-around competition at the 2016 Olympic Test Event to qualify for the 2016 Olympic Games in Rio de Janeiro. Competing with an injury, she scored 14.300 on vault, 11.600 on uneven bars, 13.800 on balance beam and 13.000 on floor exercise. One month later, she competed on vault and balance beam at the World Challenge Cup in Varna and finished second on both events (14.400 average on vault and 14.367 on balance beam). At the 2016 Olympic Games, Phan competed on two events in the qualification round: vault and balance beam. For her first vault, she performed a double-twisting Yurchenko and scored 14.700. Her second vault, a handspring pike front with a half twist, was much less difficult and scored 13.766. With an average score of 14.233, Phan was 17th out of 19 competitors who performed two vaults. On the balance beam, she scored 13.800 and finished 36th out of 82 competitors. Retirement Following the 2016 Olympic Games, Phan continued to be plagued with a number of injuries which had forced her to reduce difficulty on power events, vault and floor exercise in particular, over the previous two years. She decided to officially retire at the end of 2016 and focus on coaching and developing the women's gymnastics program in Vietnam with
