Ask MTE: Uninstall App Completely, Use New Email Address For App Purchase, WiFi Issue And Many More… (Android, Week 12)

Thanks for tuning into this week’s episode of the weekly Android Questions and Answers series. This week we are talking about totally getting rid of applications, changing the default account used for the Google Play Store, Wi-Fi connectivity issues and more.

Remember, any question you may have is surely a question someone else out there will have. With almost a million Android devices being activated daily, just know you aren’t alone. What you may think as too simple to ask, other people may be very curious to also know the answer.

The Q&A

NOTE: Some of the questions will be rephrased and will not appear exactly as they were written in MTE’s inbox, for the sake of simplifying the question and giving as much space as possible to the answer. If you believe your answer was not adequately answered, go ahead and leave a comment at the bottom. We’ll get to you ASAP.

Q: Do apps uninstall completely or leave traces behind?

A: There is still a bit of information left when you uninstall an application. Most of the information for an application is stored on the microSD card or the internal media storage for the phone. You can find the folder using a file manager application like Astro File Manager to find the file named after the deleted application and delete it. You can also search the storage areas of your device by connecting your Android to your computer in mass storage mode.


Q: How can I get my new email to be my primary email so I can sign in and use my Market apps.

A: This is is pretty easy task now. Previously you needed to master clear your phone and add in a new Gmail account. Now, you can go in to the Google Play Store and press the Menu button. There is a tab called Accounts. When you click here, you will see all of the Gmail and Google Apps accounts on your device. Click the account you want you use and you’re all set.

Keep in mind that will be totally starting from scratch with any application downloads or purchases. While the apps currently on your phone won’t go away, purchased applications are only transferable through the Google Account they are purchased with.


Q: When using my Android device over Wi-Fi the pages will not always load. If I disconnect my Android from Wi-Fi and reconnect it, everything is fine for a while. How can I fix this?

A: I have experienced this myself. A lot of phones and Android devices may use an older Wi-Fi chip not compatible with the N setting on your newer router. You can change your router to only use G. If this isn’t the case, you can try an application like Wifi Static or Wi-Fi Fixer. Both will automatically reset your Wi-Fi occasionally solving the problem.


Q: How do I close windows on the browser?

A: The answer to your question will depend on the browser. If you are using Dolphin HD, there is an X on the right side of each tab like Google Chrome has. If you are using the stock browser, press the menu button while the browser is open. You should see a button labeled Windows. When you click this button, there should be a red circle with a slash through it. Clicking on the red circle will close the windows.


Why Wasn’t My Question Answered?

If you asked a question and it wasn’t answered here, it could be one of three reasons:

  • Relevance: Your question needs to be totally relevant to the Android operating system.
  • Detail: Try to include as much detail as you can, such as the Android device and version of the Android OS you’re using.
  • Other Reasons: For some unfortunate reason, we couldn’t include your question in this edition. We’ll try our best effort to include the question in the next edition.
