In some of the polling units visited in Ilesa and Ile-Ife, majority of the voters came to the polling units with their smartphones, although security agents did not allow them to take them inside the cubicles to vote.
A security personnel, who spoke with NAN on the condition of anonymity, said the act was to check vote-buying.
He expressed the belief that the move had so far checked the incidence of vote-buying at polling units.
Mr Jimmy George, an election observer, commended security agents for preventing voters from using their phones inside the cubicles.
George , who is the National Secretary of the National Committee of Patriots, said the action of the security agents would minimise vote-buying in the election.
Meanwhile, accreditation and voting in the election continued on a peaceful note in many polling units across the state.
At Unit 12A, Ward 05 in Ile-Ife, voters were seen on the queue peacefully with INEC.
It was also observed that the card reader machines were working perfectly at the polling unit visited by NAN.
