how can i transfer data to another phone if my phone is screenless

dear apple

Apple is not here. You have posted to a user-to-user site. We are all users here.....just like you. This was explained in the Terms of Use Agreement, which you signed to use this site.

i had iphone 16 pro but my brother broked it

Were you backing up the phone regularly to iCloud or to a computer?

If yes, you can restore all of the data on your iPhone to another new phone, or to a phone that has been erased, so you can set it up again.

If no, I am sorry, but you are going to be out of luck. You will have start all over with a new phone, or your repaired iPhone and manually set up email, download apps, etc.

FYI, these are user-to-user forums. Apple largely is not here except to moderate them – so you aren't talking to Apple.

I'm sorry, but if the phone is broken, I doubt if there is any way for you to transfer data from it.

Quick Start (Use Quick Start to transfer data to a new iPhone or iPad - Apple Support) would require the ability to unlock the broken iPhone. iPhone Mirroring would require a Mac and the ability to authorize a connection on your iPhone. And, as you've discovered, the iPhone's video output is meant to supplement the built-in screen – and is not set up to be able to act as a substitute for a broken screen.

If there are copies of your data some place other than the broken phone itself, you may be able to recover using those copies. For instance,

• If you were using iCloud Photos, you could synchronize a replacement phone to iCloud Photos, and/or access your photos using the iCloud Web interface.
• If you were backing up your phone to iCloud, a Mac, or a Windows PC, you could restore the backup to a new iPhone (provided that it was running the same, or a later, version of iOS). Note that restoring a backup wipes everything on the device to which you restore it.
• If you were using e-mail accounts where the master copies of email reside on the provider's servers, you could connect a new phone to the same accounts to regain access to email and associated calendar entries.

If you backed it up to either your computer or to iCloud you can restore that backup. Also, if you synced your phone to iCloud (which is different from backing it up) any content synced can be restored to another iPhone on the same Apple Account. Email, calendars, contacts, notes and reminders actually sync to your email account(s), so if you log in to the same account(s) on the new phone they will be restored also.

You can also have the screen replaced: iPhone Screen Repair & Replacement - Official Apple Support but if you don’t have AppleCare+ for the phone that might be prohibitively expensive.

The OP should note:

Apple or an Authorized Service Provider might decide to replace the entire phone with an equivalent refurbished / repair stock phone, instead of just replacing the screen. In that case, all of the data that exists only on the phone would be lost along with the old motherboard. There are other scenarios (like breaking the screen resulting in lots of false passcode entries, resulting in the phone entering the Unavailable state) that could also lead to data loss.

I'm not saying that this would happen. I am just saying that it might happen.
