No , you can't find and signed message in app. Open it in a browser ,you can also sign a message with other wallets not only blockchain . Coins.ph doesn't support any signed message feature .Read the OP post in the firet page and follow the steps .
Thank you for your answer mate
Please excuse my noobness regarding this matter.
So when you say you can't find and sign a message it an app, you also mean to say that, like for example, in EXODUS wallet we cannot also sign messages?
i assume you are using a mobile phone and rely an apps for keeping your bitcoin.
if so then u might use mycelium apps . the steps already on the first page , just type mycelium there.
You still can use coins.ph as ur hot wallet (for daily transaction) and use mycelium only for making a signature. So if something happened to you such as your account got hijacked, you can prove you're the rightful owner and the account will back to you.
use this thread
https://bt.irlbtc.com/view/996318.0 to post your signature and wait someone to quote your signature and verify it,
you can use it as a prove later.
