Android how-to guide, Android tips and tricks.

android_guideAndroid is one of the best mobile operating systems. You can find it in smartphones, tablets, smart watches, fitness trackers, and even in your car dashboard soon.

The success of Android is partially due to its flexibility and open source.

This means Android device manufactures can easily customize Android to add some unique features. For example, Samsung uses the TouchWiz skin to add tons of exclusive (sometimes, gimmicky) features to Galaxy devices.

But there are still a lot of common functions and features shared by most Android devices. And a lot of Android device owners are fiddling around the gadget to find out how to access some existing features.

So, this Android 101 page was created to help you.

These how-to guides will cover some basic features that you can easily follow on your device (mainly phones and tablets). Of course, some advanced features that may involve using ADB or rooting the phone will  be covered as well. These Android guides should work on most Android versions, including Gingerbread (Android 2.3), Ice cream sandwich (ICS, Android 4.0), Jelly Bean (Android 4.1, 4.2 and 4.3), KitKat (Android 4.4),  Lollipop (Android 5.0 and 5.1), Lollipop (Android 6.0) and Nougat (Android 7,0 and 7.1).

  1. I’m a newbie and not sure of the correct terminology so here it goes……I decided to try the setting related to blocking calls at set times. I set the “clocks” from 9:00 PM to 5:00 AM the night before. I woke up early this morning and thought I would give it a try. Before 5:00 AM it worked perfect. When I called from a “non-Favorite” number (which is an “Unknown” or “Restricted” number by the way) it went directly to voicemail. But then when I tried calling from that number again AFTER 5:00 AM it still went to voicemail. I then thought it might have something to do with me not upgrading to the new Lollipop system. So I did that this morning also but now I’ve noticed that I can’t receive calls from “Unknown” or “Restricted” numbers anymore. They always go directly to voicemail. I’ve gone to the Call rejection menu and turned OFF the Auto reject mode and unchecked the “UNKNOWN number” from the list and it still won’t work!! What did I do wrong?? I’ve been able to receive “Unknown” or “Restricted” calls before. I have a Samsung S5, bought in December of last year. Hopefully I’ve given you enough information!! Thanks in advance for your help!!

  2. Whoops, don’t know if I just sent you a reply or not. I’ll try it again. The night before all this happened I was on the old “system” (would that be KitKat?). Then the next morning is when I upgraded to Lollipop. So, to answer your question, I guess I set up the Privacy setting under the Blocking mode menu. I can’t find the “Do Not Disturb” mode on my phone? I just went to the phone settings menu, Call rejection, Auto reject mode (turned it off), Auto reject list (made sure that “Unknown number” was unchecked) and it still doesn’t work. When I get calls from an “Unknown” or “Restricted ” number it goes directly to voicemail.

  3. Thanks for your response Simon. I guess I must have a different version of Lollipop than the one you’re talking about because I can’t find the “Do Not Disturb” mode anywhere on my phone. I’ve tried the Sounds and Notifications area and also tried the home screen “drag down” menu settings, like you showed in your tutorial. No “Do Not Disturb” mode anywhere!!?? Do you have any idea how I can get rid of the “Unknown number” listing under the Phone-Settings-Call rejection-Auto reject list? It seems like it’s a default listing because I can’t delete it!!?? I think that would do the trick, just don’t know how to do it. Would they be able to help me if I brought my phone into a Verizon store?? Thanks again for your help!

  6. Hello,
    On a Moto 3g and after the Android update I accidentally unmounted the SD card and now my contacts have disappeared and some of the apps don’t work. I have tried to remount with no success and rebooted. All the files are there on the SD card still.
    Other things like the phone security is gone and the 2nd swipe down menu has gone (with the settings icon and wifi etc options).
    Any ideas? How do I remount?
    Thanks.
