АлександрI’ve already tried a different carrier and tried reinstalling the wallet. It’s still the same—I can’t send funds from the Android wallet...
Since you are using a Lite wallet, the bad-txns-oversize error means your wallet has too many small, fragmented inputs (UTXOs)—usually from mining rewards or micro-payouts.
When sending a large amount, the transaction data built by the Lite wallet exceeds the server's maximum size limit.
Here is how to fix it:
Don't click MAX: Try sending a smaller fraction first (e.g., 30% or 50% of your total balance).
Consolidate: Once the smaller transaction goes through, those small UTXOs will be combined into a larger one, and you'll be able to send the remaining balance smoothly!
If it still fails, try switching the Light Server node or hit Rescan in the wallet settings.
