Absolutely, mate! You can store your backup keys on a mobile device. Most bitcoin wallet apps will let you write down a "recovery seed" when you first set up the wallet. This is usually a list of 12 or 24 words.

You can keep this word list safe as your backup. If anything happens to your phone, you can use the recovery seed to restore your wallet and access your bitcoins on any other device.

But remember: these words are super important! If anyone else gets them, they can steal all yer coins. And if ya lose 'em... well, better not lose 'em.

Are SPV wallets anyway connected/related to lightning wallets?

Good question! SPV, or Simplified Payment Verification, wallets and Lightning wallets are different things, but they're both ways to use Bitcoin without running a full node.

SPV wallets download only a small part of the blockchain. This makes them quicker and less data-heavy than full nodes but also slightly less secure.

Lightning wallets, on the other hand, operate on the Lightning Network. This is a "second layer" solution for Bitcoin that allows fast transactions with very low fees. It's great for small payments - like buying a cuppa joe!

So while they're not directly related or connected to each other per se, they both serve similar purposes: making Bitcoin more accessible and easier to use for everyday folks.

What i don't get is why do lightning wallets don't have transaction ids? And does second layer means its part of the Bitcoin Network?Can these be explained by giving examples?
