This is a misconception that Electrum on Andrion is vulnerable. Having fewer features on a Android version does not make it risky. You can download and use Electrum on your Android phone with full confidence. However, the desktop version of Electrum has not only more features but it is more user friendly and easy to use.
About the security of a Bitcoin wallet on android also depends on how the user is.
Nothing will be safe even a desktop electrum wallet if the user is not concerned about the security of their device and is not aware of some malware that will enter from various loopholes generated by the user.
If you are familiar with the desktop Electrum version, you may not be comfortable with the Android version. Personally, I have installed Electrum in my phone but never used it only because I do not like its interface.
Regarding the features of the Electrum wallet on Android, currently the android electrum wallet is also getting more features and a full overhaul of the user interface makes the Android electrum wallet more comfortable to use and more responsive.
The interface used to look more rigid, but for the Electrum 4.4.0 update version, it gives a new feel and a more dynamic look.
Very different from the previous appearance.
