FEMA has planned a test of the Emergency Alert System and Wireless Emergency Alerts (WEA), which allows the president to send a message to all phones in the US in case of a national emergency. This test was originally scheduled for Thursday September 20, but has been postponed until October 3 due to Hurricane Florence and the ongoing response effort.
Dave is a YouTuber, and when he streams live, it works better using LTE and his smartphone than his webcam and desktop using Wi-Fi. Leo says that in theory, they should be the same. Leo says that his Logitech C930 webcam could be misconfigured. Or, he could consider better lighting. Better lighting is always an improvement and helps the camera to pick exposure, color saturation, etc. At the end of the day, though, his LG smartphone probably just has a better camera.
Samsung announced the Galaxy Note 9 on Thursday morning, and it'll be out already on August 24. Leo says the Note phone has a lot of devoted fans, but there's also a lot of people who think it's too big and too expensive. It starts a $999, and goes even higher if you want to get more internal storage. It's a beautiful phone, and slightly larger than the old Galaxy Note 8. Samsung has put a very big 4,000 mAh battery in the Note 9. They're putting in water cooling, though, so it won't get too hot and won't explode. This is the largest battery ever in a Note smartphone.
A recent study shows that with all the smartphone, tablets, and computer screens we have around us, the quality of our sleep has really started to decline. The number one suggestion? Put down that cellphone. The LED screens are keeping your brains awake.
George has an iPhone 7 Plus and the screen goes black when he's in Facebook. Leo says that it's possible that his case could be squeezing the phone, causing it to shut down. Also, restarting the phone once a week will clear out any code that could cause problems.
Scooter X says that in iOS 9, there was an issue where Facebook would go dark. So George should make sure he's updated. While he's at it, he should just uninstall Facebook and download and reinstall the app. There could be a problem with Facebook. There was something similar happening a few years ago.
Dennis replaced the laptop in his hard drive with an SSD and it was the easiest thing he's ever done. Leo says that's the best upgrade one can do to speed up a computer.
Veronica wants to know if keeping her phone in Airplane Mode will expose her to less radiation. Leo says yes, it would. Can she also use Wi-Fi calling? Leo says it's better, but there's no evidence that it will or won't be harmful. The radiation would come from the cell phone radio, not the Wi-Fi. Using headphones instead of putting her phone up to her ear is also better.
Todd says he had a friend that was able to make her landline phone mobile. Leo says it's possible to do it the other direction. If he had a cell phone, there are a number of devices to turn it into a home phone. He could dock the cell phone into a docking station, and it would look like he'd have a regular landline phone, but it would be tied to his cell phone. There may have been a device that Todd's friend had that made her landline phone into a form of walkie-talkie, but the transmitter she would have needed for that would need to be really significant.
Richard is looking to get his first smartphone. Leo says the most important question to ask when getting a first smartphone is what phones his friends and family use. He should find out what carriers they have and how happy they are with them. Apple's iPhone makes an ideal first phone because it's so easy to use, but his friends and family will be his first line of support when he's learning to use it. The iPhone is a bit pricey and there are some good budget Android options out there.
