The 22-year-old, who was traded to Philadelphia in the summer, played 10 minutes in his side's 97-85 victory over the Boston Celtics on Friday evening.
"I was happy to be out there," White told USA Today. "I didn't think I played well.
"I'm still not making plays that are routine for me but it's just a feel thing, getting a feel back."
White was selected by the Houston Rockets in the 2012 Draft but failed to make an appearance for the team.
