Google recently released the latest version of the popular Android operating system which is Android 7.0 Nougat. The operating system will be pushed to Nexus devices soon but you will have to wait for your turn to get the update notification. If you are impatient like me then you can simply enroll in the Android Beta Program to get the push notification to download and install Android 7.0 Nougat. I enrolled using the same Google account that I have added to my Nexus 6P phone and got the instant notification to download.

Here are the detailed steps:
  • Open the Android Beta Program web page.
  • Log in using the same Google (Gmail) account that you have added to your phone.
  • Scroll down and under Your eligible devices you will find your Nexus device.
  • Click on Enroll Device.
    Android 7.0 Nougat for Nexus 6P
  • Agree to the terms and conditions and you will get a confirmation that your device is enrolled.
You will see a notification (usually instant) on your phone to download the latest Android.

Android 7.0 Update Available

If you don’t get the notification to get Nougat, then go to Android settings and navigate to About > System updates to go ahead with any other pending updates. Then you ought to see the download. The download file for my Nexus 6P was 1174.7 MB.

Android 7.0 Download Screen

Tap on Download and it will say Android 7.0 downloading. After the download completes, it is verified. You have to tap on Restart and Install and your phone will process the update package. Then it will reboot and install the system update in your device. That's it. No flashing manually.

You get the stable release and not a developer preview. Don't forget to Unenroll Device from the beta release program after installation completes. Enjoy the latest Android version along with all the goodies that come with it like multi-window support, quick switch, in-built VR support, automatic notification bundling, data saver etc. which I will talk about in detail in soon to come future posts.
Prisma is a photo editing app that adds the artistic effects to your photos. You can click new photos with it or add the jaw-dropping effects to your pictures that were previously taken. The result generated through it is a high-quality artistic graphic that is a result of some neural network and artistic intelligence technology. With over 10 million downloads in such a short time span, the app has gained notable popularity. I see photos edited through Prisma in the news feed of my social networks like Facebook and Instagram all the time.

What I also see is the colored watermark with a triangle and ‘Prisma’ written on it. It’s not that bad and most people seem to keep it in their photos letting everyone know that they too applied the Prisma filters. But if you are not a fan of watermarks and want to remove it from your photos, then you don’t need to be a Photoshop guru. There’s a simple option in the app that allows you to do so and you don’t have to pay to activate that option. The option is simply available under the settings.

Here are the steps to remove or disable Prisma watermark in photos:
  • Click the gear icon to go to app settings.
  • Switch the slider that says Add watermark to the left
It’s as simple as that. Here are the screenshots in case you get confused:

Remove Prisma Watermark from Photos

The ones that already have the watermark will stay the same, though. Now, take some great photos or edit the old ones to add some artistic Prisma filters.

Recently while trying to update an app on my phone, the Google Play Store displayed an Error 927 and the download process did not complete. I couldn’t get my app updated to the latest version and no matter how many times I tried, I kept getting the pesky error. The message said that: Update for “Google+” could not be downloaded due to an error. (927)

Here’s how it showed up on my phone:

Getting Rid of Error 927 in Google Play Store for Android

After digging around a little bit, I discovered that for me the problem was in my Wi-Fi connection and I also cleared the app data and cache of Google Play Store. That fixed the error on my end. So, I wanted to put this post up to help other people going through the same Error 927 while downloading or upgrading phone’s applications.

Since this is an error that comes up while updating apps using Google Play, we have to tinker with the Google Play App. I suggest these two methods:

Method 1: Clearing Cache and Data

  • Go to your phone’s Settings.
  • Under Device heading, locate and tap on Apps.
  • Slide your screen to reach the All apps section or list.
  • Scroll down and find Google Play Store and tap on it.
  • Click on Force Stop, Clear Cache, and Clear Data.
Note: If it doesn’t help, you can also try clearing data for the related app: Google Services 

Method 2: Remove and Add Back Google Play Account

  • Go to Android’s main Settings.
  • Under Personal, click on Accounts.
  • Tap on Google.
  • Tap on your Google Account.
  • From the Options Menu click on Remove account.
From the same place, add back your Google Account. When your account is removed, you can try clearing cache for the same apps mentioned in Method 1 i.e. Google Play Store and Google Services Framework.

Besides clearing cache/data, force stopping and re-adding your Google account, the only thing that you can do is try different Wi-Fi networks. If nothing helps, there’s always factory reset after a proper backup.
Error 923 is shown by the Google Play Store of Android devices when there is an issue downloading a new app or upgrading the one that is already installed on your phone. Users facing this problem can simply make it go away by clearing the cache and data of the Play Store in their Android device. The message that is displayed by the device goes something like, “Error ‘app’ could not be downloaded due to an error. (923)” or "Update for 'app' could not be downloaded due to an error. (923)". Of course, the ‘app’ can be any application on your smartphone.

Here are screenshots of it from my phone:

Google Play Error 923

To fix Google Play Store Error 923 on your Android phone or tablet, follow these simple steps:
  • Open up your phone’s Settings.
  • Under Device, tap on Apps.
  • Find Google Play Store in the list. Depending on your Android version, it might be on the All
  • Click on Clear Data and Clear Cache buttons and confirm your action.

More thoughts about Error 923

I got this error when my Wi-Fi connection was having problems. So you can try disabling and enabling Wi-Fi. Some people have found that turning on the airplane mode on and off helps. If you find that you still get this error while downloading/upgrading apps, you can try it in other Wi-Fi networks and hotspots other than yours.

But if you keep getting this error then, you can try other guaranteed methods like wiping cache partition or even factory resetting your phone. Those will remove everything from your phone.
If you are looking for an Android emulator with performance and speed in mind, then Droid 4X should be on the top of your list. It offers a seamless experience of running the world’s most popular smartphone operating system in your Windows PC. After downloading it for free and installing it in your system, you will find that it’s simple, it has all the features you’d want in an Android emulator and did I mention that it’s free?

If you are interested in getting this free software, then head on to their official website. You will find the link to get it as “Download Simulator”. It will download the installer to your computer. Next, you will have to double click and open the Droid4XInstaller.exe file. Give it the necessary permissions and it will begin to copy all the files. It did take a few tries for me to set it up as the downloads seem to stop abruptly for me.

Once the setup process is complete, open up the new piece of software that is on your PC. If you have been using other Android emulators for PC and Mac, you will find that this one is considerably fast. It doesn’t seem to slow down the computer or take a lot of memory. I’ve had this problem with other emulators.

Droid4X – A Fast Android Simulator

In your first run, you will get a short intro and then will be asked to add a Play Store account. You can open a new Google account or use an existing one for it. You might be required to do some verifications to make it work. The home screen or the first screen is brightly themed as opposed to the dark themed Android setups. You will only find a few apps i.e. SysFolder, HelpCenter, Google Settings and the always useful, can’t live without it—the Play Store. It doesn’t come pre-installed with any bloatware or apps that you do not need, not yet and not ever; let’s hope. The Sysfolder has the default system apps like Gallery, Browser and the Settings which shows Android 4.2.2 as of now in the About phone section. Finally, on the bottom right, you will find the full-screen key and the key simulation option for better input controls.

Install all the Android apps and games that you want and run them easily in your Android PC. If you have a touch screen laptop, then you’d be using it as a tablet. But there are ways to control the emulator using the keyboard and mouse. The important thing is that it runs all your favorite Android apps and games without any hassle. It also uses the Windows 10 notification system to notify us about things like installation processes.

In the controls section, you will find three keys: (1) Back, (2) Home and (3) Recent. It’s present in the bottom left part. On the top right along with the standard window control buttons, you will find the settings and help menu. The settings menu is quite useful if you want to choose your hotkey, define what the minimize key does, set the screen resolution, volume, CPU. There’s even an option for external APK installation. That will cover you for a lot of things.

Overall, the emulator or simulator as they call it is great. I’d use it over others now since it’s so much faster and responsive. On their official website, you will also find that you can use your Android or iOS phone as a controller for games and then use the Droid4X on your PC as a big screen game device. Gamers rejoice. So, give it a try and I think that mobile gamers who are looking for a bigger screen and better game controlling options will absolutely love it.
Recently, with advanced permission management options in Android Marshmallow, users are seeing errors that says “Can’t open microphone” when an app tries to access the mic. This error comes up basically due to an app not being able to access the phone’s mic because it doesn’t have the necessary permissions for it. This issue has been reported by users who try to use the Google Now app along with the Ok Google voice command.

Can't Open Microphone Error

They see an error as shown in the screenshot above. The way to fix the “Can’t open microphone” error is to dig into the App permissions of the application that shows the error. There you can turn on the Microphone permission by dragging the slider to the right.

Here are the detailed steps:
  • Go to Android Marshmallow’s main Settings.
  • Tap on Apps.
  • Find the app for which the error is displayed. If it is Google Now then tap on Google App.
  • In the App info page, tap on Permissions.
  • Under App permissions, drag the slider of Microphone towards the right by tapping on it.

Now you will be able to use the microphone without facing any issues provided that the hardware itself doesn’t have any problems. Also, the steps above are for turning on the microphone permission for the Google Now app. You will have to tap on a different app in the list of applications if you are trying to fix it for something else. The rest of the steps are the same.
The RPC S-7 AEC-0 and RPC S-7 AEC-7 were frequent problems that were displayed by the Google Play Store in Android devices. Here is an example of how the errors is displayed: Error while retrieving information from the server [RPC:s-7:AEC-0]. Though the problem seems to have gone down with fixes and updates, there might be different older devices that are still facing it. This post is dedicated to those users who still have to go through different RPC errors at times when downloading and upgrading apps.

Since this is an error with the Google Play store, there are some common fixes that we can try to make the error go away. The first one is always restarting the phone and also disconnecting and re-connecting the Wi-Fi router, data connection etc. I am assuming that you have already done it.

Here are the things you can try:

Removing and Adding Your Google Account

Every Play Store is associated with at least one Google account. You need an account like the one that your Gmail provides to be able to use the full features of an Android device. So, what you want to do is remove the associated account and add them back.

Here’s how you do it:

Removing Google Account


  • Bring up the main Android Settings.
  • Scroll down to find and tap on Accounts.
  • Tap on the Google.
  • Tap on your google account(s) that is/are listed as a Gmail address.
  • Tap on the options menu and then on remove account. Confirm it.


  • Open Google Play
  • Agree to the terms and conditions.
  • In the prompt, tap on Existing Google Account and enter the details (username and password).
Complete the steps and try the installation/update process again. There is a high chance that it will work.

Clearing Cache and Data of Google Play Store

For some people, after removing and adding back their Google account, they can try clearing cache and data of the Google Play Store app. It seems to clear up the error as well. You can even try this step first.

Here’s how:
  • Open up Settings.
  • Swipe towards the right to the tab that says All and it lists everything.
  • Scroll down and tap on Google Play Store.
  • Then tap on Clear Cache and Clear Data. Confirm you actions.
It will definitely solve the RPC errors for most users now. If it still doesn’t and the problem stays forever, then the only thing we can do is reset the phone back to factory settings. It will take some time and effort to backup and restore everything.
Out of the many troublesome errors that we come across in Android, Error 505 is one of the common ones. It is an error produced by the Google Play store when installing or updating apps. A message box opens up which says Unknown error code during Application install: -"505". The problem is prominent in phones with Android 5.0 Lollipop.

If you want to fix Error 505 in Android then there are multiple ways that you can try. There is no single fix for it and different users find different error solving methods for error 505 seem to work for them. The methods include restarting your phone (simplest method) to factory resetting your phone (wipes everything).

Anyways, here are the different fixes that you can try to fix Error 505 in Google Play Store of Android 5.0 Lollipop:

Simplest Method: Turning it on and off

The basic or the simplest thing that you can do when any electronic device breaks is to turn it off and then on. It is the same thing with your phone. Turn it off and turn it on. The same goes for the Wi-Fi connection. Try disconnecting and connecting your internet in your phone as well as turning off and on the Wi-Fi router. If you are using data, then try doing the same for it i.e. switching it off and then on. A few lucky users might find that this simple fix will work for them.

High Probability Method: Clearing Cache/Data of Google Play Store

The cache and data of Google Play store has different information and files related to app installation. So, you can try clearing the saved cache and data.

Clear Cache and Data

To do that:
  • Go to your phone’s Settings.
  • Find the option that says Apps and tap on it.
  • Scroll right towards the tab that says All.
  • In the list of all apps, scroll down to find and tap the one that says Google Play Store.
  • Within the next screen, click on Clear Cache and then on Clear Data
Now try installing or updating that app that was facing the Error 505 issue. It should work.

Ultimate Method: Factory Reset

If nothing else works for you, you can try resetting your phone to its factory settings. Note that everything is wiped off and you will have to set up the phone as if it were new.

To flash ROMS and upgrade your Android device manually, you have to unlock the bootloader of your device. To unlock the bootloader for your Nexus 6P phone, you will have to turn on the developer options, connect your device to your computer and use fastboot (and adb as well) to run some commands and unlock the bootloader.

Please note that when you unlock or lock your bootloader, it will erase all the user data. It’s like doing a factory reset; so you want to back up everything. Also know that having your phone’s bootloader unlocked means that it is vulnerable and the system won’t be able to check for corruption. You will even get a warning during boot that says:
Your device software can’t be checked for corruption. Please lock the bootloader. Visit this link on another device: g.co/ABH. Press Power To Pause.
So, only unlock the bootloader if you know what you are doing. Just use it to flash a ROM and then lock it again immediately.

Here are the steps to unlock and lock Android bootloader in Nexus 6P phone:

In Your Phone

  1. Enable the developer options by going to Settings > About Phone and repeatedly tapping on the build number 7 times.
  2. From the new Settings that appear (System > Developer options) make sure that it is turned on along with OEM unlocking and USB debugging.
  3. Connect the phone with a wire to your computer and give it the permission if it asks for it.
Make sure that you have installed abd and fastboot that comes with Android Studio. If you don’t want to install Android Studio, then use this simple ADB, Fastboot and Drivers 15 second installer by xda-developers. Also, add adb and fastboot to the command prompt so that it makes your job running the commands simple.

In Your Computer (and phone for confirmation)

  1. Go to run and type in cmd to access the command prompt.
  2. To make sure that everything is good type adb devices and you will see your phone under the List of devices attached.
  3. Type adb reboot-bootloader
  4. To Unlock the Bootloader, enter the command: fastboot flashing unlock
To lock it, enter the command: fastboot flashing lock
  1. Use the volume keys to navigate and power button to confirm the action on your phone.
  2. Type fastboot reboot to restart.
