Polling was slow in the initial hours, but gradually picked up pace as the day progressed, official sources said.
In Jaintia Hills district under Shillong constituency, two EVMs were replaced due to malfunctioning.
Deputy Commissioner Sanjay Goyal told PTI that one EVM was replaced before the polling began at Lamin (B) polling station, while another at Khliehriat was replaced after it stopped beeping after 26 votes were polled.
