Androids: how to display phone 1 on phone 2?

[isaanistical]

I have a Samsung (android 14) with a badly damaged screen for which the lovely manufacturer has no replacements. It is so bad it is effectively useless.

 

Can anyone advise whether it is possible to connect it to another Android - eg my Samsung tablet - so that I can display the contents of the phone on the tablet while using the phone? To make calls, Whatsapp, facebook, etc, not watch videos.

 

Thought this might be a simple question, but net searches keep telling me I should 'mirror' with HDMIs and casting software. I think it should be simpler than that but what I know about this you can write on a pinhead with a pneumatic drill. What I have in mind is more like a visual version of a mobile hotspot. It's not as simple as joining the two devices via USB cable, is it?

No you cannot connect two phones together in order to display one phone's screen on the other. Phones simply don't have the hardware to receive, decode and display an HDMI signal.

 

You *may* be able to use a USB-C to HDMI cable to display your phone's output on a TV or monitor, but you'll have to check your phone's capabilities in that regard (I know Samsung's higer end models do; I don't know about mid range or budget models).

 

Failing that you may be able to wirelessly cast your display to a smart TV.

 

The only way to mirror the display to another *phone* would be with some kind of screen mirroring software; I don't use them so I don't know which ones could work but if you want to investigate further then you can take a look at anydesk, spacedesk or splashtop.

Thanks for reply, sorry if I failed to make it clear: I want a tablet to act as a stand-in screen for my stricken phone. I very much do NOT want TV or video. I want to use the phone (as per normal) while out and about, only using the tablet to see what is on the phone. HDMI etc just can't be relevant here. 

 

Phone: S21 (victim of the dreaded vertical lines and now impossible to read stuff)

tablet: A7

in case that helps.
