John is experiencing a brief flash of vertical lines against a white background on his Android tablet. He's swapped out the tablets more than once and wonders if this is a hardware issue or software issue. Leo says that since John is putting the same apps on the tablets, no matter which model he tries, that points to an app or software issue. Leo suspects that the tablet is making a quick adjustment in the video mode as it does in the app. It could be normal since it goes from tablet to tablet. The common denominator is the user, so that's where he can focus his troubleshooting efforts.
Leo says that the Google tablets would be updated first, but frankly, it seems that Google's Nexus 7 and 9 have been somewhat abandoned with no updates in the last few years. He's concerned, though, that he won't be able to use LTE on AT&T. Leo says he'll want to make sure it shares the same band as AT&T supports. The Google Nexus 9 does support every frequency but 700mhz. Leo says that was a recent development and it's what he'll want.
Dave recently updated his Samsung Galaxy S6 and now the fingerprint sensor doesn't work right. Verizon says nobody else has complained about it. Leo says that it's probably a bad update that happened over the air. It's fairly common. The only thing he can really do is to reset his phone. That will wipe the phone and reinstall the operating system. But before he does that, he should turn on 'Backup to Google' in the settings. He should let it back up and then reset the phone completely.
Dave needs to download images he has from his Google Nexus 6. It says it's being moved to an SD card, but he doesn't have one in his phone. Leo says that Dave needs a file manager to be able to find the photos on his drive. ASTRO is a good one, and it's free. There's also ES file manager. He should look for the download folder. It will allow him to move it around.
Pat keeps getting a notification of a security update on her Android phone. Should she do it? Leo says absolutely. Mobile phone companies have started doing monthly security updates to keep phones more secure and functioning properly. Being that it's from her mobile company (Verizon), it's safe. Leo says it may be a good idea to wait a day or two to be sure it works right.
Bob bought the Amazon Fire TV and it works great. But he can't figure out how to get Google Play on it. Leo says that Amazon created it to use their store, and so to have Google Play on it would be competing, and Amazon doesn't want to pay for Google's services.
Fern is only getting audio from YouTube videos, but the actual video is just colored lines. Leo would try going to youtube.com/html5 in her browser on the Android tablet. She should make sure YouTube isn't trying to send her Flash video content. Leo also suggests getting the YouTube app from the Google Play store. If she still can't see videos with it, she should take it back to Verizon, where she got it.
David came across an app called Clean Master that's supposed to protect and optimize your mobile device. Leo isn't so sure. He's not really impressed with download numbers, either. It's whether the app really works. And even if it does, it's unnecessary. David doesn't really need it. It's not doing anything important and some of the things it does is bad. It can certainly kill his battery life. It will also delete temporary files that will just cause his phone to download them again when he returns to that site. So it's not really doing anything.
Barbara is thinking about switching from the iPhone to the new Samsung Galaxy S7. Leo says that while the S7 comes with 32GB, she can put up to 200GB of additional storage in a miniSD drive. But it's not like it expands her memory for apps. That's only for storage. Leo prefers the S7 by a long shot, but the iPhone is great for the average user. Barbara already knows how to use it, and has apps in the ecosystem. So why change? She should just get an iPhone with more storage.
Louis bought a Samsung Galaxy S7 Edge and he's discovered that the home key has become disabled after charging with his wireless charger. He restarted it, but is getting the same thing. He even took it to the store and replaced it, but it's still happening. Leo says that there's a problem with the wireless charger. Or it could be an app. Leo suggests doing a factory reset and not installing any apps. See if it charges and if the problem goes away. If it does, then he'll have to go through each and every app until he isolates the one app that's causing the issue.
