There's no love lost between national broadcaster ZBC and some Zimbabweans.

And on election day, Twitter users have been sharing their scathing assessment of the station's coverage of the poll.

One shared the composite below showing foreign TV stations giving wall to wall coverage of the election compared to ZBC's broadcast of a local drama.

In the lead up to today's poll, ZBC had already been criticised for its bias against the opposition on its election campaign coverage.

Here are other critical reviews:

Polling stations have now been opened for more than seven hours.

Here on the BBC Africa Live page, we've heard from voters as well as some of the key players:

Zimbabwe President Emmerson Mnangagwa has been keen to show that his country has turned a corner with this vote.

Whereas in the past, election observers from some parts of the world were not welcome, they've come in large numbers for this vote.

For the first time in 16 years, EU and US observers have been allowed to monitor the vote.

There are also observers from the African Union, the Southern African Development Community (Sadc) and Zimbabwean NGOs.

They're all there to ensure the vote goes smoothly.

The BBC's Fergal Keane met one observer who's come home from exile:

Voter turnout is high and 90% of polling stations opened on time, head of Zimbabwe's electoral commission Priscilla Chigumba told journalists.

The commission is confident that by 7pm (17:00 GMT) the voting process will have been completed, she added.

Photos are being shared on social media of former President Robert Mugabe casting his vote in Harare's Highfields neighbourhood, alongside his wife Grace.

One journalist has tweeted that this is the "first time" in Mr Mugabe's 94 years that he has voted for "someone other than himself for president".

The leader of a breakaway faction of the Movement for Democratic Change has been filmed entering a polling station to vote in Bulawayo, Zimbabwe's second-biggest city.

Thokozani Khupe is among 23 candidates running for president.

Rival factions have battled for control of the MDC party since the death of its former leader Morgan Tsvangirai earlier this year.

Mrs Khupe opposed Nelson Chamisa's appointment as acting party leader at the time, and decided to leave the party to stand on a separate MDC ticket.

There's no agreed figure on Zimbabwe's unemployment rate but there's a widespread acknowledgement that the situation is hard for many.

And the country's graduates are not immune.

One unemployed young man was snapped while queuing to vote in his formal university garb:

Zimbabweans have been speaking about their hope that the election - whoever ends up winning - will mark an improvement in the economy's fortunes.

• Zimbabwe election: Hustling for cash to survive

So far, election day has gone smoothly across much of Zimbabwe. A fact that no-one in this turbulent country takes for granted.

Voters, glad to see the back of Robert Mugabe, are talking about the need for change. For a fresh start.

For many, that change is best delivered by the governing Zanu-PF, now under new management following November’s removal of President Robert Mugabe, and seeking to end Zimbabwe’s isolation and poverty.

But there is a significant groundswell of support for the opposition MDC Alliance.

Voting today, its new leader, Nelson Chamisa declared that, provided there was no rigging, victory was a done deal.

Huge efforts are being made by local and foreign monitors to ensure the results are credible and that, whoever wins, Zimbabwe can begin the hard task of fixing its broken economy.

No surprise what the big story is in ZImbabwe's newspapers today, but they all seem to be taking a slightly different view.

The independent Newsday newspaper headlines opposition leader Nelson Chamisa saying that he will win. The state-owned Herald is more neutral saying that things are "all set" for the poll:

The business newspapers are more concerned with the economic outlook. And Zimbabwe's Independent newspaper says "it's do or die for the president".

The BBC's Pumza Fihlani is now back in the capital, Harare, after talking to voters in a rural area an hour north of the city.

She's in Harare's densely populated Highfield area.

One voter told her she wanted a "better future for her niece" and that her whole family had come out to vote:

Pumza is also reporting that there are long queues at Rusvingo Primary School in Highfield, which is leading to some delays.

There's also some confusion about what queue people should be in:

Former Zimbabwean Vice-President Joice Mujuru, one of 23 presidential candidates, voted earlier in the capital, Harare.

Mrs Mujuru is the leader of the opposition National People's Party and head of the People's Rainbow Coalition.

She was once touted as an heir to former President Robert Mugabe, serving as vice-president for a decade before she was ousted in 2014, in a move led by Mr Mugabe's wife Grace.

In February this year, her party said she had been attacked while out on the campaign trail.

While all eyes are on the elections in Zimbabwe, news has come from South Africa that could spell trouble for former first lady Grace Mugabe.

Our reporter in Johannesburg, Milton Nkosi, says a court there has lifted her diplomatic immunity.

This means that state prosecutors can start criminal proceedings against her.

The news relates to allegations that Mrs Mugabe assaulted a 20-year-old woman in a hotel room in Johannesburg last year.

She was granted diplomatic immunity allowing her to leave the country without being questioned by police.

She later denied the alleged assault saying she acted in self-defence.

The US ambassador to Zimbabwe has tweeted these photos of him among voters and talking to electoral officers at two different polling stations in the north and south-east of the capital, Harare.

On Sunday, a senior official from the US Department of State's Bureau of African Affairs tweeted a message of support for Zimbabweans in their "desire" for a "free, fair and credible election".

Assistant Secretary Tibor Nagy added that, having met the two main candidates, he hoped their pledge of "commitment to a peaceful process" would be matched by their actions.

"The world is watching," he said.

Earlier on we showed one voter's kit of bottled water and a novel taken in preparation for a long wait in the queue.

Here is another person's supplies - chocolate, crunchy snacks, fruit juice, water and "a back-up phone".

"I'm ready, I'm prepared, I'm organised", Floridah Mapeto captioned her tweet.

Pretty impressive, but it doesn't quite top Kenya's "Githeri Man" - the voter captured queuing in the country's elections last year with a bag of boiled maize and beans in hand.

There's a hope in Zimbabwe that the economy will be put right after the election, Zimbabwe analyst Stephen Chan told BBC World News.

He said that people are not interested in wild promises:

In Domboshawa village about an hour's car ride north of Harare, many had been in the queue even before sunrise.

The first group of voters were mainly elderly people but there were some youngsters too. A local primary school has been converted into a polling station for today’s important poll.

Surrounded by mountains and rolling hills, the villagers are in good spirits, chatting and laughing.

But the stakes are high. Zimbabwe’s future is in the balance and nothing is certain.

It has been a hotly contested race but there is an air of optimism unlike the nervousness I’ve witnessed covering previous elections here.

“This election is different, there hasn’t been violence," one voter tells me. "It’s a good sign”.

After casting his vote, he tells me his prayer is that whoever wins puts Zimbabwe first.

"We have suffered enough", he says as as he walks off on to the winding dirt road.

We're now seeing some clearer pictures of incumbent President Emmerson Mnangagwa voting in Kwekwe, about three hours' drive south-west of the capital, Harare.

South Africa's News24 is tweeting that the president said the country "is experiencing democracy never witnessed before".

He has tweeted this image of himself casting his vote with a caption saying "the voice of the people is the voice of God".

Mr Mnangagwa's main challenger is Nelson Chamisa from the MDC Alliance. There are 21 other candidates on the ballot paper.

Almost 5.7 million Zimbabweans are registered to vote of a total estimated population of 14 million. That's more people than ever before.

This is 38-year-old Sembre Machekra whoe spoke to the BBC's Christian Parkinson:

He was first in line at Chinamhora primary school polling station (an hour's drive north of the capital, Harare), arriving at 04:30 (02:30 GMT). He told Christian: "Since 1980 there has been no freedom or freedom of speech. So I want to express that through my vote."

Meanwhile, 50-year-old Pauline Zinanzwa says she is voting so that her children can get jobs.

Zimbabwe's incumbent President Emmerson Mnangagwa has rejected suggestions that there will be problems with the vote, Reuters news agency reports.

He told journalists that it will be free and fair.

A journalist from South African national broadcaster SABC has tweeted a picture of the president at his polling station:

And SABC news anchor Peter Ndoro has posted pictures of the media interest in the president voting:

We've been reporting about the long queues of voters seen at some polling stations, and it looks like people are preparing for a long wait.

One voter has tweeted a picture of a water bottle and big novel that should see her through:

Reuters news agency captured this moment in a queue at a polling station in the capital, Harare. Vendors are hoping that while people are waiting they'll be using their phones and here we can see one man selling all-important airtime.
