Electrum version 3.3.7. installed on Xiaomi mi9t pro. Nowhere else. Password protection has been enabled. On April 1, the wallet had 1.23595057 btc. Today I switched to a wallet to transfer part of the funds and was very surprised. Wallet balance 0. It turned out that on April 3rd at 23:05 a transaction was sent for the total balance. The transaction was send to address unknown to me: 13k4rgQ6b9LdBt6pvgLR5MSV6wAhujFpgq No one has access to the phone. Electrum has been downloaded from the official site. I know about phishing and always carefully check everything. Never updated the application. I download all applications for the phone only through the play market. Please tell me how this happened? What have I done wrong? for what reason have I lost all my savings?

How did you create your wallet from Electrum mobile? If someone created it for you he might be the one who stole your Bitcoin. Or if the seed backup is created from other wallets like Bitpay?

If not, then there might be a keylogger in your device. Actually Xiaomi Phones is not secured as Samsung with Knox.

The similar issue below the same as hosseinimr93 posted above.
- [uncensored-r/Bitcoin] Bitpay wallet hacked - what went wrong?

That's why I suspected that this address is controlled by Bitpay? I'm not sure but if your seed backup is created from Bitpay and imported it to Electrum mobile... Maybe?
