Did Samuel act as a priest on top of being a prophet?

Thinking about the life of Samuel, you can see that in some ways lived like a priest on top of being a prophet, despite being from the half-tribe of Ephraim. One, he was brought up in the temple by Eli and thus lived out his life in priestly service together with the sons of Eli. Two, he performed some duties that were traditionally assumed to be for priests. For example, by appointing leaders and offering sacrifices. In Numbers 27, it is Eleazar the high priest who commissioned Joshua. However, it was Samuel who anointed both Saul and David. In regards to offerings, in 1 Samuel 13 we see Saul waiting for Samuel to offer the burnt offering and peace offering. According to Leviticus 1, priests and the offerer were the only ones involved in making the sacrifice. So in regards to this info, did Samuel act as a priest?
