galaxy s4 display on galaxy s2

[quaakfrosch]

Good evening!

I recently dropped my old Samsung galaxy s2, completely destroying its display; otherwise it seems to be undamaged. Unfortunately usb debugging was not activated, so I'm having a hard time saving the files I had on the phone. (I know that there are ways of activating usb debugging through recovery and adb, but so far I've had no success with that.)

Now, I also have a galaxy s4 and I noticed that the connectors of the displays of the s2 and s4 look the same. So I was wondering if there's any danger in trying to connect the galaxy s4 display to the motherboard of the galaxy s2, and if there is any chance of it working?

Has anybody tried something like this before and could give me some advice?

I appreciate any help!

Seeing as display technology has advanced tremendously between the S2 and S4 release, I would think they are incompatible. Also, it's electronics. I can't say it will cause damage, but let's be realistic. Finally, if the information is that important, I'd look for a used S2. I bet one can be had for very short money.

Thank you for your quick reply!

I thought that perhaps the display connector was some kind of a standard, like pci, where it doesn't matter how far technology advances (e.g. you can connect a modern graphics card to a 10 year old motherboard, as long as the plug fits, i.e. as long as it has a pcie-slot), because the connector only powers the display and takes care of communication between it and the motherboard, while all the actual display-ing and touchscreen-ing is just left to the component (i.e. it is some sort of a blackbox, from the motherboard's point of view).

However, I see that from the manufacturer's point of view, there's no incentive to create or follow any such standard, as 'display compatibility' really isn't a major smartphone issue (unlike with standards like pci or usb, where you really want to have the possibility to connect a wide variety of devices). Still, it would have been interesting to find out, but I don't think I'll risk my s4 to do so.

So I guess I'll just follow your advice and try to get my hands on another s2 to harvest its screen.

Thanks again!
