Android Q&As: Copy/Paste In Android, Re-rooting Phone After Firmware Upgrade And More… (Week 4)

After a month of writing this series, there seem to be a some somewhat generic questions coming through. There also some very specific questions. However, if you could add the model of the device, which version of the OS you have and any other key information would be very helpful in helping answer your questions.

We will make an attempt to answer as many questions as we can each week.

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: How to perform cut/copy paste on an Android phone?

A: In 2.3 and higher, you can copy text in a SMS or an email you are composing if you press and hold the text and select the action from the pop-up window. If you are talking about selecting text from a web browser, Opera Mini and NetFront Life Browser will give you this option. Otherwise, there are a few applications like Copy And Paste It (trial) that work great. However after the trial is done, there is a cost to keeping it.


Q: Can I switch back to an older version of the Android OS?

A: The short answer is no, unless you have rooted your phone. There isn’t an easy way to downgrade your Android OS version without rooting your device. Once rooted, you can change the ROM to whatever is available to you. This includes experimental builds of new versions of not yet released OSes.

Q: I rooted my Android phone and installed ClockWork Recovery on it. I later has a service technician upgrade the firmware and my phone got unrooted. How do I root my phone again.

A: Different phones have different methods to root them. When a firmware update comes out, many times there is a “patch” to fix the exploitation in the software which allowed your phone to be rooted. There are sites like XDA Developer Wiki or CyanogenMod that have great walk through on rooting different devices.


Q: Very often I have difficulty in “powering off” my ‘phone. Usually I press the power button then “Power Off”. It then fades away and it’s only later I find that the phone hasn’t turned off. How can I fix this?

A: Most commonly there is an application holding up the process and not letting your phone power down. Check that you have not installed any system maintenance app that is always running in the background monitoring your activity. If yes, check inside the app and see if there are options to prevent monitoring during powering off. I have also seen devices with slower processors or phones with low memory taking a long time to power down or power up. Take a look at your available space, perhaps this may be low. If so, try moving applications to the SD card or deleting some apps and try powering it down. Typically you want between 15MB and 30MB free. More free space is better though.


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.
