eth_sendTransaction different behavior on Smartphone than on desktop browser

[andrekat]

Hey!

I am sending a transaction to call a method of a smart contract. The code is working fine on my desktop, where he sends the transaction to the contract address (as specified in the "to" field). However … on my phone or in the MetaMask app itself, it tries to deploy a contract and therfore the transaction fails?!

This is the code I am using to send the transaction (using “request”)

.request({
method: "eth_sendTransaction",
params: [{
"from": "VALIDADDRESS",
"to": "CONTRACTADDRESS",
"data": "HASH_OF_INVOKED_METHOD_SIGNATURE_AND_ENCODED_PARAMETERS"
}]

Transaction sent through MetaMask Mobile:

Transaction sent through MetaMask Desktop Extension (works as expected)

What is going on here? Did i miss something?

Expected behavior
Same behavior on smartphone as on desktop

Smartphone (please complete the following information):

• Device: IPhone 12 Pro Max
• OS: iOS 14.6
• App Version: v.3.0.1 (didn't work in previous version as well)

To overcome this issue right now:

1. Use the approve() function of an BEP-20 / ERC-20 - this does somehow work on phone (app) and desktop browser

2. Use transferFrom() on the server side
