## How do I use a node with username & password?
```username:password@node.address:portnumber```

## The app always crashes as soon as I open a wallet!
Users of Zenfone MAX & Zenfone 2 Laser (possibly others) **MUST** use the armeabi-v7a APK as the arm64-v8a build uses hardware AES
functionality these models don't have. If this does not help, please report the problem.

## I am having problems with my BTC transaction
Please contact the friendly people over at http://xmr.to for support - you will need your XMR.TO Secret Key.

## My new testnet wallet does not update
Since testnet block times are highly variable, the algorithm calculating block height does not
produce good results - so in general your testnet wallet will not work out of the box.

The remedy is simple: restore from seed and the correct / current block height. Take the block number
of your first transaction or the current block height from the
[Testnet Blockchain Explorer](https://testnet.xmrchain.com/).

## I cannot select and copy the mnemonic seed
Copying anything to the clipboard on Android exposes it to any other App running. So this
is a security measure to keep your seed safe(r). 

## My storage is getting full
Newly generated wallets are stored in `.new` in the main wallet folder.
They are never erased (for now). You can delete this whole folder from time to time.

Also, the backup folder named "`backups`" (formerly `.backups`) is never automatically cleaned up.
You may want to do housekeeping manually with a file browser.

All wallet files (`testnet` and `mainnet`) are stored in the main `Monerujo` folder.
So be careful erasing stuff. One of the future releases will split the wallets and move `testnet`
 wallets out of there.

## Do you have any screenshots of what it looks like and how it works?
No, but it looks fantastic. Just check it out.

## Can I use existing wallet files?

If you want to use existing wallet files, you need to copy the wallet files from you current Monero client. These are:
```
WalletName
WalletName.address.txt
WalletName.keys
```

### From where?

This depends on your installation - you could search for them in your home directory or check the settings of your current client. Places to try are:

- Windows: `%USERPROFILE%\Documents\Monero\wallets`
- Mac: `~/Monero/wallets` (for the GUI) or `~/.bitmonero/wallets` for the daemon.
- Linux: `~/.bitmonero/wallet`

...or just search for `WalletName.keys`.

### What if don't have these files?

Keep calm and make a new wallet.

## Why does it make a 'monero' folder?
This is a new feature of monero core to share certain key images with other monero forks.
