Deputy Chief Constable Katy-Barrow Grint of Gloucestershire Constabulary is in our studio talking to BBC Points West presenter Amanda Parr about whether teenagers should, or shouldn't, be considered as victims of domestic violence.
And David Wright, chief executive officer of online safety charity SWGfL, tells Amanda manufacturers need to make it easier for parents to monitor phones.
Miranda Wilson, from Bath, set up Teched Off to raise awareness of the dangers of social media and smartphones for young people.
She said: "What I would like is really simple; one is legislation to stop under-16s being on smartphones and social media and two is a public health campaign so parents are educated about the harms."
At a discussion event in Bath this week, she screened a film about the dangers of smartphones for children, featuring interviews with health professions who are part of the group Health Professionals for Safer Screens.
Dr Rebecca Foljambe, founder of the group, said children are dealing with issues like "very poor sleep" and body image concerns.

Twelve-year-old Louis, a student at Bournside School in Cheltenham, said he had been "spending a lot more time playing games and football with my brother" after cutting his smartphone use over the past month.
He told us he would usually be on his phone "before and after school", mainly to play games and watch videos but said "frightening videos did keep coming up" on certain apps.
Faith, 12, said she has been "spending more time with family" and "becoming less reliant on screen time" since going smartphone-free.
Benjamin, 11, said he used to watch YouTube regularly, but when his mum took it off his phone he said it was the "first night he spent hours outside in the garden with his sister".
"I've noticed I'm doing so much more outside and my sleeping patterns are better," said Jemima, 13.

Pupils at King's Oak Academy in South Gloucestershire spoke to BBC Points West presenter Amanda Parr about online safety.
Student Lillie told her she would like parents to help educate them in online safety.
She said: "When you're not told what to do, how are you supposed to be expected to know what to do? If you're a parent and you're going to let your children have a phone and be online, you need to take on that responsibility and educate them, and lay down the rules."

Karl Hopwood is an independent e-safety expert and works with the network of Safer Internet Centres across Europe.
He told the BBC that social media can be a positive place to "communicate and learn", but that young people can be exposed to "very challenging content on subjects such as suicide, self-harm and eating disorders".
He said sextortion scams (blackmailing people when they have shared explicit images) was becoming more widespread on mainstream social media platforms.
"There's a lot to be concerned about."
He said the most powerful tool was talking to young people: "We would want young people to come and tell us when things go wrong. In reality, they fear the reaction of their parents... their parents will ask where that happened and the parents will say 'well you can't use that then'.
"We need to think carefully about how we react, otherwise they won't come and tell us when they need ."
He said for older teens, talking to them about their online reputation affecting job and university applications, or visas for visiting the United States, can be "quite powerful".
He advised parents to use s, external [external website] to help safeguard young people.

Earlier this week Gloucestershire reporter Georgia Stone met staff and students at Bournside School in Cheltenham, which is on a mission to delay children getting smartphones until at least Year 10.

Throughout the day we've been sharing details of our investigation into what teenagers are being shown on their social media feeds.
Reporters Harriet and Andy spent a week posing as six different teenagers, all from the West, who had interests ranging from Sabrina Carpenter to Call of Duty, and simply scrolled for ten minutes a day on each of their Instagram, TikTok and YouTube feeds.
But while their viewing was initially largely related to their interests, troubling and potentially harmful material began to appear on their feeds - including posts apparently referring to suicide, poor mental health and violence.
The following are screenshots we gathered throughout the course of our investigation:

Professor Paul Howard-Jones, professor of neuroscience and education at the University of Bristol, ed BBC Radio Wiltshire today to talk about some of the benefits of technology.
He said we "can't pretend technology isn't part of our children's lives".
During a discussion about mobile phones and online safety, he said he was not a fan of "blanket bans" on devices in schools.
"It's a really important source of learning," he said. "We've got to get the balance right.
"I think that technology is actually the future and we, as adults, learn so much from our mobile phones.
"I'm really in favour of doing everything we can to maintain a positive, healthy learning environment in schools.
"I sort of think there is a time when mobile phones are really helpful for learning. Think about how much we learn as adults. Are we really preparing children for that world?
"They will use their phones when they get home from school anyway and they will use phones eventually and they have to know how to restrict the content they're receiving."
But he said access to inappropriate content was a concern and wanted to see continued political pressure on social media companies.
His advice to parents?
"It's really important that we have a conversation with children so they know how to regulate their use of technology and how they reduce those occurrences [of seeing harmful content] and we also talk to them about what they are encountering on the internet.
"It's all about digital hygiene and teaching kids and adults ing the internet safely."
Social media companies we have ed say they are taking the issue seriously and are working hard to remove harmful content.
'Danger in criminalising children'published at 14:46 British Summer Time 15 May
14:46 BST 15 May
Debbie Beadle, chief executive of the Wiltshire based charity FearFree, told us that there was "a danger in criminalising children".
"I don't think we just should rely on laws," she said. "Ultimately what we should be looking at is early intervention and education around what a healthy relationship is.
"It's about looking at the messaging that our young people are getting on social media, through the games they're playing, the conversations that they're having at schools."
Ms Beadle spoke to the BBC as part of an investigation into the role social media has played in abusive relationships between young people, which you can read in full here.
Cases of teen 'domestic abuse' 'most weeks'published at 14:34 British Summer Time 15 May
14:34 BST 15 May
Deputy chief constable of Gloucestershire Police, Katy Barrow-Grint, said cases like those we've heard about in our investigation published today, external were not uncommon.
"Most weeks there will be cases presented to us where there are teenagers who are boyfriend and girlfriend, where there is physical or sexual violence, which would be classified as domestic abuse if they were over 16," she said.
Gloucestershire Police, she added, is working on a pilot project with the Home Office, looking at potential changes in the law around under-16s and domestic abuse.
A 'toolbox on how to control women'published at 14:19 British Summer Time 15 May
14:19 BST 15 May
As part of our investigation into young people subjected to domestic abuse in which the perpetrator uses social media (which you can read in full here), reporter sca Osborne spoke to Sarah O'Leary, chief executive of Next Link which provides domestic abuse services in Bristol, South Gloucestershire and North Somerset.
She told us how concerned she was that social media and other online content is fuelling abusive behaviour and being used as a "toolbox on how to control women".
"We know there's been a rise in online misogyny and encouraging young men to act out those misogynistic values," she said.
"Much of the pornography that boys will view is violent towards women and girls.
"I do think a lot of the boys that are witnessing that online and are being radicalised."
What about AI?published at 14:04 British Summer Time 15 May
14:04 BST 15 May
Meg Haldane, a cyber protection officer for Avon and Somerset Police has been speaking with BBC Radio Somerset's Simon Parkin in the studio this morning.
"We need to really start to think more about our own digital footprint and the information we're sharing about ourselves," she said.
With the conversation turning to artificial intelligence (AI), Ms Haldane said: "The way that AI has evolved has meant that it is now incorporated in a lot of the fraud and online crime that is targeting us.
"It also feeds into the misinformation and fake news. AI makes it trickier to distinguish between what's genuine and what is not.
"Criminals are using pictures like Martin Lewis and Elon Musk to create AI generated images endorsing investment scams."
Our reporters dive into what teens are really scrolling throughpublished at 13:48 British Summer Time 15 May
13:48 BST 15 May
Early this morning we published our investigation into what young people are really seeing on their phones - made possible by our reporters Andy and Harriet setting up six profiles for fictional teenagers and spending a week scrolling through their feeds.
Despite searching only for innocent interests like fashion, music, football and gaming, we saw unprompted videos discussing poor mental health, violent crime and adult material - all pushed to children aged 13 to 15.
Andy and Harriet will appear on BBC Points West's special programme this evening to discuss their findings, but you can read their full report here first.
