YouTube has always been a great place for exploring music for free. With millions of user-uploaded videos and with the help of the smart suggestion feature, you may never run out of songs to play. However, the platform is not ideal for listening to music on-the-go when you have to use your mobile connection because the size of the videos may be too large. You also have to stay connected to the internet constantly to enjoy the music on YouTube. Luckily, it is possible to convert YouTube videos to mp3 files for listening offline on your phone.

You probably cannot imagine Android without the Play Store and its apps. Apps bring color to Android’s operating system and are the reason why the Android ecosystem is thriving. From time to time, you may download an app, use it for a while, and then forget that it exists. Look at your Android device, and see how many apps you have. Now, try to remember the last time you used some of them. You may be shocked once you realize that you only used some of your apps one time, but they have been sitting on your phone for months. These apps take up space. If you have an unused app and you want to delete it, this tutorial will show you how to uninstall Android apps.
If you have an Android device that is malfunctioning, the most common way to fix this issue is by performing a hard reset. A hard reset deletes all of the device’s data, including apps you have installed, and returns the phone to its original settings, just as it was when it was first released from the factory. However, a hard reset should always be a last resort. There is a better way to deal with a device that goes on a boot loop, freezes, or is just slow. Sometimes, problems encountered on a device are due to incompatible or buggy applications that were recently installed. Testing your Android through Safe mode should be considered before performing any reset or before taking your device to a service center. This tutorial outlines how to fix malfunctions by booting into Safe Mode on Android.
Safe Mode for Android phones is a diagnostic mode that helps you determine the source of the error that is causing your Android device to get stuck, restart, go on a boot loop, run slow, or freeze. If you have just installed a third-party app on your HTC phone and you are experiencing problems, then trying to fix these issues by booting into Safe Mode is recommended before performing a reset or having your device checked by a service center. This tutorial shows how to put your HTC phones in Safe Mode.
Downloading and installing apps from the App Store is easy. In fact, it is so easy you can inadvertently accumulate an endless list of app icons in your iPhone app drawer. Many of these you probably do not even remember of downloading. Aside from the mess these unused apps can create on your iPhone, every app requires a certain amount of storage space, a critical part of an iPhone since the device has no expandable memory. The best way to handle unused apps is to uninstall them. This tutorial describes how to uninstall iPhone apps quickly and easily.
If you have recently installed a third-party app on your LG phone and you are now having an issue with it (e.g., freezing, boot loops, slow performance, etc.), then booting your device into Safe Mode may help you fix the problem. Booting LG phones in Safe Mode puts them in diagnostic mode, and your phone will have limited functionality to prevent buggy apps from starting. If you want to know how to start LG phones in Sade Mode, keep reading.
A common fix for most computers whenever there are problems with the system is to start in them in Safe Mode. When in Safe Mode, a computer will boot without performing the standard boot processes. (e.g., Autoexec.bat and config.sys files will be disabled, auto-run programs will not auto-run, and device drivers such as printers or scanners will not load.) This allows users to fix problems and program conflicts which cannot typically be resolved on standard boot. Safe Mode is also available for Android devices. Similar to its computer counterpart, Safe Mode for Android allows the device to run in a diagnostic state so that you can check if a recently installed app is causing problems within your system. This issue may cause phones to freeze, reset, or run slow. This tutorial focuses on how to boot Samsung Galaxy phones into Safe Mode.
