Dave wants to know if he can downgrade his Google Nexus 7 from Lollipop because the update has really slowed down his tablet considerably. Leo says that he could try rooting it, and then put on a custom recovery that will allow him to do it. Dave should check out XDA Developer Forum for tips on how.
Mike is looking to replace his tablet and smartphone with a larger screen phone. But should he get the Samsung Galaxy S6 or the Note 4? Leo says that the Note 4 is larger, has removable batteries, and has a stylus, while the S6 doesn't. And the Note 4 is available now. So Leo would get that.
Ray is concerned with security on his tablet, and is wondering if he should have antivirus for it. Leo says that mobile devices are designed in an era where malware is a serious threat, so these newer operating systems are inherently safer because they tend to be sandboxed. If he still wants some added protection, LookOut is a very good antivirus app. That being said, Leo doesn't use an antivirus program.
Carlos upgraded his Samsung Galaxy S5 from Sprint to the Galaxy Note 4 with Verizon. But it comes with a lot of stuff he doesn't like. Leo says that Carlos can root it, but that requires unlocking the boot loader which involves a risk of bricking the phone. Carriers don't like it because it's a workaround for how they want him to use the phone, like tethering at no cost.
Dwayne misses the days of having an actual user manual. Leo says those days are long gone. Everything is to be found online. Dwayne also says there's an app for Android he wants to put on his computer. Is that dangerous?
Leo says that Android is safe because it's largely an emulator that runs programs, so it's easy to run Virtual Machine, or Bluestacks and run it. But it's a bit disappointing because emulators don't use the Google store, so the availability of apps is limited. He could sideload the .APK file, though.
Jeremy needs to reset his Android phone, but he wants to keep everything configured the same way. Leo says that he'll get his apps and passwords back (as long as he has it set to backup to Google). But it won't save his setup and organization.
Roger says his Samsung Galaxy S3 is having battery life issues. Leo says that every battery has a limited battery life of about 500 charging cycles, so he should just replace the battery and he should be good to go. If that's not working, then the charging system may be messed up, and a simple system reset should make the phone like it was when it came from the factory. Google will have already backed all of his data backed up.
Julian would like to upgrade his Asus TF700T 4.2 tablet with detachable keyboard because he's getting a warning that says "website not responding." Leo says this could actually be an issue with router. Julian says there's a lot of other issues they're having with the tablet, though, and he'd like to upgrade it to an Android 5.0 device.
Mike uses his phone as his internet access and he wants to use Netflix from his Android phone wired to his HDTV, but he has issues with audio sync. Leo suspects that the phone isn't powerful enough to drive it. He did get a Chromecast, but it requires a Wi-Fi signal to work.
There are other options. Leo says that using a MiFi card may help, because then it would convert the 4G signal to Wi-Fi. Also, because he rooted the phone, that could be adding to the issue. But rooting helps him to tether and use the Chromecast that way. This could violate his deal with Sprint, though.
