10 Android tips you must know - Secure and Optimize

How to keep your Android Secure and Fast:

Know which apps uses most of the memory

Android 6.0 is a new OS which came out with some impressive features. One useful feature was the ability to know which apps used most memory (like Facebook, Google Play Store). If there are some apps which are kept unused and take up more memory, you can uninstall them, but only the unnecessary ones. Mostly games consume more battery life and device’s RAM, whether in PCs or laptops or phones. All the functions of the device depend on the RAM available.

Open the Settings>tap on Apps>tap on Memory (here, you will be able to view how much of RAM is available and how much is used)>tap on Memory used by apps (here, you will get the list of apps and how much RAM each app is consuming>tap on the drop-down which reads 3, 6, 12, 24 hours (here, you can view the RAM used during that duration).

You can also see how frequently that app is being used as apps that are always running uses more RAM.

Marshmallow has introduced the Doze feature which turns on automatically when your battery becomes low or the device uses motion detection and gets into a deep-sleep state when the device is not in use, thus puts it into an ultra power saving mode. It turns off background refresh for apps but, you will still receive the important notifications. The phone will set off your alarm in the morning even if the battery isn’t charged. You must be wondering about getting this feature but your device isn’t running on Android 6.0. Don’t worry! You can get this feature on older phones also by installing the Doze app and no root is required. Doze feature runs in the background and is a very clean, organized and well-designed app.

Exclude apps from the Doze feature

As mentioned above about the Doze feature, you know that it turns on automatically and the user gets little access control as to what should or shouldn’t be on. This means that if the feature is on and that time you are expecting that you may get an important email and you might not receive it. You can exclude those apps (which are most important and productive) from Doze. It is an easy process because it is a built-in function and doesn’t require an app or root access to manage Doze.

Go to Settings>Apps>go to the Battery Preference>tap on the more button that is displayed on the action bar which is at the top of the screen>select Battery Optimization from the menu>go to the drop-down to view the All apps list (all the apps that are installed on your device)>tap an app you want to exclude>set it to Don’t optimize to exclude the apps from the Doze feature.

Check the noise level of your surroundings

You must be wondering whether you are too loud or not. Or must be a little irritated with your neighbor playing music at a loud sound and want to check if it is within the sound barrier. Deciber is the solution. This is a free app that measures loudness and gives you an accurate result without the need for any extra equipment. You can even include your location as it connects with the camera and takes the screenshot. You don’t need any external permission to install or run this app. It quickly records the rise and fall in sound level.

Clear the Google Play Store Cache

Clear Google Play Store cache - Speed up Play Store and Android performace

If your device is slow and hangs in between, it is better you clear the cache of Google Play Store. This solves many problems and is a simple easy step. We sometimes face error while downloading, installing or updating an app and sometimes can’t connect to the right service.

In the 6.0 version, go to Settings>tap on Apps>tap on the Google Play app>press on ‘Storage’ for longer period>release the ‘Storage’ section then, a new screen will open up with the ‘Clear Cache’ and ‘Clear Data’ options for the Google Play Store app.

Tips: Common Play Store issues and solutions

Visual and haptic feedback when you make a typo

The Autocorrect feature inbuilt in your phone which tells you when you make a typo and fixes your mistakes the way you want and sometimes is the cause of the mistake. This feature is both a boon and curse. Autocorrect does solve our problems like a spelling mistake or a word we’ve missed. It does one-fourth of the task for us. It works efficiently with spelling but grammar correction is not so good.

Tipo is a free Android keyboard that reports when you’ve made a typo. It flashes it with red color and you get a haptic feedback that an error has been made and the autocorrect couldn’t fix it. The upgraded version is also available at $0.99 which will help you to improve your spelling.

You just have to install Tipo and set it as the default keyboard. To check this app, go to Hangouts and compose a message. When you make a typo, the keyboard will turn the error red for a few seconds and if enabled, you will get a haptic feedback from your phone. The haptic feedback is a great thing, which doesn’t let you down.

Fix the app which could not be downloaded

Sometimes you may encounter that Google Play Store fails to download an app and there are different reasons for this cause. If you are getting a 495 error which prevents an app from being installed. There are two solutions to this 495 problem:

Clear Cache and App Data

Go to the Settings>tap on Apps>Swipe to the “All” button>check first the Download Manager>tap on Clear Data>return back to the “All” button>find the Google Play Store and clear the cache>restart your device.

Now you should be able to download an app.

Network problem

Apps having a problem in being downloaded may be because of the slow connection or network problem. This problem may be solved if you switch to another network or instead you can use Wi-Fi connection. If neither one works for you, connect to the Wi-Fi network and reset the router. You can do so by holding the power button for a few seconds and turn it on after 30 seconds. This resolves the problem in most of the cases.

Use the built-in File Manager

Android M has a built-in file manager. The older versions also came with a built-in app to access the device’s storage (internal memory or memory card). This app got lost somewhere as the versions changed, but now the upgraded Android version has brought it back and it’s very easy to use. It is limited in features and a default file browser is set up in their system.

Go to Settings>navigate to Storage & USB option>tap on it>go to the bottom of the screen where you will find Internal Storage>tap on the Explore option. The file explorer lets you go through your folders easily with the search bar and you can change the layout also (you can view all your files and folders in a grid or list layout). You can also arrange files according to their name, size, and date.

To share, move or delete a file/folder: tap and hold to select it (file/folder)>the share or delete option will appear in the action bar. The folder icons appear in small thumbnails. The UI’s interface and themes are not impressive. But, a file explorer is worthy.
