Can we use EtchDroid to create Ubuntu installation media?

EtchDroid to create Ubuntu installation media

EtchDroid sounds like it meets your requirements and has a good rating and sounds safe. I gave EtchDroid a trial and had good results.

• Downloaded and installed EtchDroid from the Google Play Store. https://play.google.com/store/apps/details?id=eu.depau.etchdroid&hl=en

• Connected USB flash drive using micro USB to USB-A converter.

• Started EtchDroid and selected "Write raw image or ISO".

  

• Selected the Ubuntu ISO file

  

• Selected the target USB from upper right on the screen:

  

• And clicked the write icon on the lower right.

  

At first I thought nothing had happened but when I returned later I found that the USB was ready for a Live boot or Install.

There are similar apps that flash image files to USB using Windows including Etcher and Win32DiskImager, and from Ubuntu including Etcher, Startup Disk Creator and Gnome-Disks. This is a handy free app to have on your phone.

My only complaint is that this app will not write to an internal SD card, but I understand that this is a safety feature.
