The firm says the G2 addresses the problem that mobiles become harder to control the bigger they get. The South Korean company recently reported its strongest ever mobile phone figures. However, analysts are split over whether or not their latest innovation is a winner. The new device features a 5.2in (13.2cm) screen and is powered by Android. Its rear keys can be used to adjust its volume or - if pressed for a longer time - to activate the device's camera and note-taking software. LG suggests that using a back-button to take a self-portrait with the front camera also makes it easier to take a steady shot. "Moving the main buttons to the back of the phone gave users more control since this place was where individuals' index fingers are naturally located," it said. "Researchers also found that moving the buttons also resulted in fewer dropped phones when adjusting the volume while talking." LG overtook Huawei to become the world's third best-selling smartphone maker in the first three months of the year thanks to demand for its Nexus 4 and Optimus range, according to market research firm Gartner. One of its researchers suggested the move could indeed help address issues consumers have with the design of bigger mobiles. "This is a potentially interesting concept for LG because as phones get larger, the position of the phone in the hand and how you use it is going to change," said analyst Brian Blau. "Whether the button on the back proves to be a winner long-term has yet to be determined, but it deserves some amount of consideration." But another tech consultancy, Juniper Research, dislikes the concept. "I'm not convinced that this represents a killer design," said analyst Michael Wiggins. "The positioning of the navigation button doesn't appear to be particularly user-friendly, either, particularly if - given the size of the device - you're an individual with smaller hands. "For a few more millimetres of screen, it's not a great trade-off." LG v Samsung LG announced that it shipped a record 12.1 million handsets over the April to June period. However, its mobile unit is not as profitable as that of Samsung or Apple because much of the demand was accounted for by its lower-margin mid-range devices. Coupled with an increased marketing budget and weak sales of its TVs, it meant the firm still posted a 9% drop in net income. At the time, So Hyun-chul, an analyst at Shinhan Investment Corp declared that LG needed a "mega-hit smartphone to dramatically raise its profit". The launch of the G2 was notable for being the first time LG has chosen to host a special event in the US to unveil a handset - something other manufactures Samsung, HTC and Nokia have become accustomed to. The new device's other stand-out features are a 13 megapixel camera with image stabilisation and 24 bit/192kHz audio playback, which LG claims can reproduce music at a quality that is "far superior to a CD". "This is LG's top-tier play and from a specs point-of-view it looks good versus the Samsung Galaxy S4, which is the probably the nearest phone in the market," said Stuart Miles, founder of gadget review site Pocket-lint. "It's now down to whether people believe strongly enough in the LG brand versus Samsung's when it comes to choosing which phone to go for. "Ultimately I think LG has a chance, but Samsung may just end up steamrollering them with marketing." LG said the G2 would go on sale first in South Korea and then North America, Europe and other markets over the next eight weeks.
LG is hoping to shake up smartphone design by placing the only physical buttons of its new flagship model on the rear of the handset.

Irfon Williams was forced to move to England to receive the drug Cetuximab to treat bowel cancer. A medical review of the drug followed a campaign by 45-year-old Mr Williams and it is now available in Wales. But the cancer patient, who lives in Bangor, Gwynedd, has learnt that despite initial treatment success the disease has now spread. "I have wondered, very, very occasionally, whether I should have gone so public - should I have just gone quietly and got on with things," Mr Williams said. "But very quickly I think back to the impact that some of our campaigning has had, and I've no regrets at all. "Nothing but good can come out of the campaigning." Mr Williams highlighted the decision to hold an independent review of how patients in Wales access drugs not normally available as one of the victories for the Right to Live campaign. He was invited to sit as the only patient on the panel by Health Secretary Vaughan Gething in September. "I think it shows the government has listened to patients' voices and understood that the process was unfair and a very difficult one for families to go through." However, his focus has now shifted from his campaigning following the news his cancer has spread to his lungs and other parts of the body, and can no longer be cured. "I need to concentrate now on staying healthy, enjoying my life and living as long as I possibly can - I'm not planning on going anywhere in a hurry." The father-of-five said that included preparing his younger sons for the worst, at the age of five and seven. "It really is on their mind, especially Sion who is seven. One of his biggest fears is that daddy is going to die, and unfortunately I can't reassure him that daddy isn't going to die. "We are preparing them for that in a way that is appropriate to their age and development without being too morbid about it."
A campaigner has said he has no regrets over making a personal battle against cancer public in a fight for treatment.

By Will GrantBBC News, Mexico and Central America Correspondent For inmate Lillian Allen, the story of Michaella McCollum and Melissa Reid's arrest at Lima's airport for allegedly carrying some 11kg (24lb) of cocaine has brought back some painful memories. Blinking back the tears, the 48-year-old Northern Irish woman remembers her own arrest as she tried to board a plane out of Peru. She did not realise it at the time, she says, but she was acting as a drug mule. "I came here to meet someone and he asked me to take some bags back for his brother," she recalls wearily, as though the memory itself is weighing her down. "I looked at the bags he gave me and they were just normal handbags, children's schoolbags. I never saw anything inside." Stitched into the lining, however, was about 8kg (17lb) of cocaine. When Lillian reached the departure gate, the authorities stopped her in her tracks. 'You have drugs' "They said: 'You have drugs'. I said 'No'. I went with them and they took my suitcases out. They put a cotton bud inside the bags, and took it out and said 'coca'," she explains. For carrying the cocaine, Lillian was eventually sentenced to eight years in prison. She paid a lawyer to help her plead her innocence but his advice was simple: "You have to say you're guilty to get a shorter sentence." Lillian tells me her story on a cold concrete bench in the women's wing of Ancon 2, a prison on the outskirts of Lima. A modern facility, it does not yet suffer from the endemic problems of other jails in Latin America, namely overcrowding and crumbling infrastructure. The majority of foreign women in prison in Peru used to be housed in Santa Monica jail in Chorrillos. It was notorious for its crowded and unsanitary conditions, and the prison authorities have started to move many of the detained foreigners to Ancon 2. There are currently 325 foreign inmates in the jail, more than 100 of them women, most of whom are there on drug charges. Ms Reid and Ms McCollum are likely to spend some time there, even if they are eventually cleared. The stories are frequent and familiar. Anna, not her real name, told me that a year ago, she came to Peru for eight days with her then-boyfriend. She says he planted drugs in their luggage as they travelled back to Spain and has since refused to support her claim that she knew nothing about the cocaine. It is a common theme - women trapped by unscrupulous men who make others take the risk, and the blame, for smuggling drugs. 'Constant fight' The prison library is staffed by two friendly European girls, no older than Ms Reid and Ms McCollum. They explained how the economic crisis at home had pushed a lot of women into running risks they might have otherwise avoided. "Pay off all your debts at once," one of the girls, from Madrid, told me with an ironic grin. The debt she is paying now will run into years. She has formed a close bond with her Italian cellmate, but says every day in Ancon 2 is a struggle to stay sane. "We were just saying to each other before you came in, this place is a constant fight to keep from going mad," she says. Drug smuggling can attract long sentences, and the frustratingly slow pace of the legal system is like an endurance test of their patience, they say. But they try to stay positive by listening to their music as they put the library books in order, and planning trips they hope to take together when they get out. When the talk turns to the two UK girls, they have both heard of their case. "Even if they didn't do it, they may as well confess. It'll be easier in the long run," they explain. "I hope they come here - we'll look after them." 'Little girl' Lillian Allen, though, is the inmate in the jail who perhaps most identifies with the two young women, particularly with her Northern Irish compatriot, Michaella McCollum. "I always said I never wanted another girl to come in here from my country," she says, wiping a tear from her cheek. "She's young, she's only a little girl. She could be my daughter, she's younger than my sons." Regardless of whether Michaella McCollum's claim to have been kidnapped and forced into carrying cocaine by gangsters is believed by the Peruvian authorities, it is likely to take a long time for her - and Melissa Reid - to extricate themselves from the country's tangled legal system. "I will help them," says Lillian wrapping the white scarf she knitted in one of the prison workshops around herself a little more tightly as if for comfort. Barring an unprecedented dismissal of the charges against them, they are going to need it.

Two UK women suspected of drug smuggling could spend time at Ancon 2, a prison where many foreigners are detained. What is it like there?
