I thought that's the same fake electrum app with this thread:
Fake Electrum.Due to the price of bitcoin lately, there's another proliferation of these fake apps and they're circling again through Google Play. The interface of that another fake electrum is very much different from the legit one.
Download from Electrum site is true but be cautious of phishing sites of Electrum.
The official website of electrum has reminders about fake and phishing links. Bookmark it and don't just type it on google.
