[Amazon Fire Phone] jondecker76:
As a long time Android user, I (like most others) had a bit of a hard time getting used to using the Fire Phone's FireOS. Having used the OS for a couple of weeks now, it's not quite so bad once you get used to a few things and learn a few new tricks. Just wanted to start a thread for collecting these types of things that will help others making the transition to FireOS. I'm purposely omitting the fact that google play store can be side loaded whenever possible (sideloading the play store is something I highly recommend everyone with this phone do) so that I can focus on tips and tricks that actually relate to transitioning to FireOS.

Side panels Most everyone at this point is probably aware of the extra info panels that can be accessed by swiping in from the left or right edge of the screen. I have mixed feelings on this myself, as it's used well in some apps (like swiping from the right edge while typing a text message to add pictures), and not very well in other apps (and yet not at all in some apps). Additionally, it's not always obvious if an app does support this feature, or if a certain app will put these options in either the left panel, right panel, or both.

Back Button There is no back button on the Fire Phone. This was a cause of confusion at first. The back button has been replaced with a "swipe up" from the bottom of the screen to go back. This can be a bit finicky at times, but I've found that if I start a short swipe up from the top edge of the home button, it works nearly every time. Additionally, some apps seem to treat this a little differently, as from time to time I will see "back" and "menu" soft-buttons appear at the bottom of the screen when this gesture is used.

Screen Shots You can take a picture of whatever is on the screen by pressing the power and volume down buttons at the same time

App Switcher This is usually accessed on a NORMAL Android phone by long holding the home button. In FireOS, the same is accomplished by double-tapping the home button (the long hold in FireOS brings up voice search). This is the fastest way to switch between apps and gets you around having to navigate the carousel. Also, while in the app switcher, you can swipe individual apps up to kill the process AND remove them from the carousel. I like the Fire Phones implementation here much better than stock Androids. You can double-press the button very fast and this is much less disruptive to workflow while multitasking than pausing for a long press. I think Amazon implemented the switcher and action of the home button beautifully.

Home Button I initially found the behavior of the home button weird. On first press (from a running app), it will take you to the carousel. Additional presses from this point will cycle between the Carousel and the app tray.

App Tray Aside from subsequent presses of the home button, the app tray can be slid up by touching and dragging the bottom row of quick launch icons upward while in the carousel. Likewise, you can continually drag the app tray downward to eventually reach the carousel at the top. It will seem more logical if you picture in your mind that the Carousel sits at the top of the app tray.

Another App Tray annoyance is the lack of alphabetical sorting of apps. While I've found no way to do this automatically, apps can be dragged and dropped in the app tray in any order you like. Apps can either be dragged on top of eachother to create collections (folders), or dragged in between other apps for changing the sorting order. A bit of a pain initially, but pretty easy to keep up with once you get your current collection sorted initially.

Lastly, to get the most from your 4 quick launch icon slots - you can use collections (folders) there as well! This is a feature I'm really using a lot lately to make navigating and the lack of a normal launcher much easier! For example, currently I have the following 4 quick launch collections: "Communication","News","Organize" and "Media". Within the "Communication" collection, I have Phone, Contacts, Messaging, Email, Facebook, Messenger, and Snap Chat. Within the "News" collection, I have Yahoo, Silk Browser and Weather. Within "Oganize" I have Notes, Calendar, and Our Groceries. Within Media I havePhotos, Music, Prime Music, Instant Video, Plex and Netflix. Since using collections in the quick launch area, I find that I rarely ever use the app tray, as my most frequently used apps are right there, easily accessible from the Carousel.

Facebook Mesenger If you're used to using the floating chat heads, and missing them in FireOS, here is a tip. Go to messenger, and enter the settings. Navigate to "Chat heads", ensure the switch is set to "On" and that the "Hide when using apps that take up the full screen" checkbox is NOT checked. For some reason the FireOS launcher/carousel is treated like a full-screen app.

Music Fire phone comes with a "Music" app. But don't confuse this with Amazon's own "Prime Music" app - they are actually two different apps! For those that use the prime music service, do yourself a favor by installing "Prime Music" right from the Amazon App Store. Why this isn't on the phone by default is beyond me!

Cellular usage data As most of us have to keep tabs on our data usage, I find this to be a nice built-in feature (though not the easiest to find). You can set your monthly limit and view current usage under "Settings->Wi-Fi & Networks->See your cellular data usage"

Carousel I'm not a huge fan of the carousel, though I'm finally starting to adapt to it.

EDIT: I'm starting to become a huge fan of the carousel. It has forced me to become organized, and the ability to do simple actions (delete emails for example) without opening an app is just awesome once you get used to it.

There is one cool feature, and that's "pin to front". You can make any number of apps appear at the beginning of the carousel by long-pressing and selecting "pin to front". This has limited utility, as this is only efficient for pinning a few frequently used apps to the front of the list, but still useful once you start using it.

Also, the dragging and dropping apps from the app tray works to replace the default quick launch apps that appear at the bottom of the carousel.

For non-app items (books, music, etc) that appear in the carousel, long-pressing will reveal an addition option of "Pin to app grid", which will pin the book/music/whatever into the app grid for easy access just as if it were an app.

For Pinned items, you can reorder them kind of crudely with a long press and using the "Move to front" option

Status Bar By default, the status bar auto-hides. You set it to always be visible in Settings->Display

Lock Screen This actually has a very little-knows and very cool feature called a "Locket". This allows you to add a number of photos that can easily be accessed from the lock screen. The utility of this isn't immediately obvious, so consider this scenario:

You bump into an old friend in the mall and they ask how your family is doing. Instead of pulling out your phone, getting to the app tray, pulling up the "Photos" app and searching for pictures to show - you can use the locket feature to do this much more efficiently.

To setup and/or access the photo locket feature, from the lock screen, simply swipe from right to left (instead of swiping up to unlock). This enters the photo locket, where you can add more photos, or swipe left and right to view the collection of photos in your locket. It's actually a really neat feature and has some real utility (I can't count how many times I've had to fumble through navigating through my entire photo collection to show pictures of my kids to someone I haven't seen in a while. This really makes it easy)

Silk Browser Another thing I'm not very keen on - though if you plan on using stock FireOS, learning to properly use the app will help.

EDIT: Ok, the browser is growing on me now.

It can be a bit confusing since there is a menu button in the upper-right hand corner, a different menu in the left panel (accessed by swiping in from the left edge of the screen), and other options such as tab switching that are only visible at the bottom of the screen only at certain times. I'll try to detail some of the common functions here:

Bookmarking pages

Bring up the page you want to bookmark, then use the menu button in the upper-right hand corner to add the bookmark

Desktop View

Use the menu button in the upper right-hand corner and navigate to "Request another view", which will allow you to select the desktop view

Clearing browsing history

Access the menu in the left panel, and go to settings, then "Your Data" -> "Clear Browser Data". From here you can clear just history, or anything else such as cookies, etc. You can also clear sites from the history list one at a time by using the left panel menu->History and long pressing the entries you wish to delete.

Tab Management

This took me quite some time to figure out. Sometimes I would notice the tab switcher at the bottom of the browser, other times I wouldn't. To make these tab controls visible again, simply start scrolling the current web page back towards the top of the page and the tab controls will appear.

Private Browsing Mode

This keeps websites from saving to your history, saving cookies, etc. Like other options, it's not easy to find in the Silk browser. To go into private browsing mode, use the Tab Management above to enter the list of tabs. On this screen you will find the option for private browsing.

Offline Reading

One interesting feature that is useful (but poorly implemented) is "Reading Lists", which stories/web pages for offline reading. It's confusing, because you use one menu system to save to the reading list, and yet another menu to access the saved items. To save a page for later viewing, use the menu button in the upper right-hand corner and choose "Save to Reading List". To access the actual reading list to either read, or remove items, use the left panel menu->"Reading List"

Default Search Engine

The search engine can be changed from the default (Bing) to either Google or Yahoo by going to the left panel->Settings->Search Engine

Cloud Photos Prime members get unlimited storage for backing up photos. Unfortunately, it's poorly implemented in FireOS and ONLY allows for automatic uploading of ALL new photos at this time. But what if you want to be able to specifically select only the photos you want stored on the cloud? Unfortunately in stock FireOS this isn't yet possible. However, if you have installed the Google Play Store or are familiar with side loading, look for the "Amazon Cloud Drive Photos" app - which oddly enough is published by Amazon for general Android devices, but not available to their own Fire Phone via their own App Store. At any rate, this is how to get around the limitation of the default implementation.

I'd love to hear tips from others and continue learning to use FireOS more efficiently. The tips I outlined above have made this a very usable OS for me, even though I flat out hated it at first. I'll try to keep up adding tips and tricks from others to this master list.
