John got an Amazon Fire Tablet and he'd love to wipe it clean to get rid of having to go into Amazon for everything. Leo says one thing he can do is put the Google Play store on it. Once done, everything else on Android is available. Leo says he stopped using the FireTV because it was all about Amazon as well. He could maybe "root" the tablet in order to make it Android only.
Jon would like to convert his old Windows laptop into a Chromebook. Leo says to check out Neverware. They have a list of compatible hardware and he can install Neverware and turn it into a Chromebook that's up to date and secure. Check out this article at XDA Developers.
Mike wants to know how to jailbreak his Android phone. Leo says that jailbreaking is for the iPhone and it's not recommended because it exploits known security flaws, which is dangerous. The Android phone equivalent is "rooting" which enables administrator access. This allows one to put other firmware on there. But the Samsung Galaxy mobile phones are very difficult to root because Samsung doesn't want users to. But if users go to XDA Developers and input the exact model of their phone, they can find out how to do it.
BJ wants to know if he needs to reinstall the OS on his tablet in order to change the carrier for it. Leo says no, and since BJ's tablet is with Verizon, he can just replace the SIM card with another. If it doesn't work, he can go to Verizon and ask them to unlock it. They have to unlock it by FCC mandate. He shouldn't need to unlock it, though.
Rob has an old Android phone and he doesn't like his carrier. Can he unlock it and go with another carrier? Leo says he should as long as his account is in good standing. Even if he's no longer a customer, they should still do it for him. He should just call and ask them politely. He should not pay to unlock a phone, though. If he has to, Rob should go to XDA-Developers.org and look in there for instructions.
Steve was given a Barnes and Noble Nook reader. Can he watch movies on it? Leo says that the Nook had very limited space and used a proprietary format, but he may be able to hack it to give it more options, including watching the movies he wants. He should head over to XDA-Developers to see how to "root" the Nook. His real problem, though, is copy protection. The Nook only supports movies with Cinema Now DRM. But that's part of the fun of hacking old technology like a Nook.
Al has an LG V20 Android phone and wants to know if he should get another one for a secondary device. Leo says that LG is about to come out with the LG V30. Al wants one that has a removable battery. Leo says that there isn't a popular phone that does removable batteries anymore. The drive for thinner mobile devices has pushed to get rid that feature.
Jerry wants to get his Samsung Note 4 mobile device repaired. It keeps booting. Leo says that mobile devices are now generally considered disposable. Leo says to try refreshing the phone. To do this, he should go to Settings > Backup and Reset > Restore to Factory Defaults. If that doesn't work, then he could try calling Samsung and ask if they would repair it. They'll really want him to buy a new phone, though.
Tim wants to know why he's not getting his phone updated. Leo says that since Tim is a subscriber of Straight Talk, it's likely that they aren't sending out all the official updates. Leo advises talking to Straight Talk about when he can expect the next update for his phone.
The only other option is to root it and install it himself, but that's not for everyone. He can find out how to do it at XDA Developer Forums. He'll have to follow the directions to the letter or he'll end up bricking his phone.
Debbie has a Samsung Galaxy S7 phone and she wants to view the manual, but they don't have it in English. Leo says that Samsung makes different phones for different regions and it sounds like Debbie's is for a different region. The only real difference is the radios that are in it. She can download a PDF version of the manual, that's not a big deal, but she'll want to be sure it's compatible with the carrier she uses and the data bands she'll want.
