I'm relatively new to this forum, but I beg the question what is the best way to sweep a paper wallet from an Android phone? I have a Google pixel 5a.
Are we talking about smaller amount of coins you want to sweep from paper wallet and spend?
If this is the case you can use any open source Bitcoin wallet and scan QR code with your phone, but best option is to use airgapped phone disconnected from internet with Electrum wallet.
Here is one very good step by step tutorial by Crypto Guide how to do everything correctly:
