@Furryball this is a nice advice but not all wallets found on play store are fake, though it’s always recommend to do some research before installing any crypto wallet on your phone. Furthermore newbies can yet get scammed if they’re using desktop wallets as it happened in the case of electrum wallets where the wallet showed a PopUp saying people should update it, and by the time people could spread the word that it was a scam it was too late. Hence I would request you to add one more point to the op, that no one should update the wallet from inside it, rather people should go their official site and download the latest update.
