[Xiaomi Mi Mix 2S Questions & Answers] Adamyno:
First, sorry my english. If anything is incomprehensible, ask me.

Not long ago I dropped the device and fell to a gravel, not defended by the ?Gorilla Glass. It became a spider web. Essentially, the device was working, sensing the touch, and the display was relatively intact in just one spot a little pressed. I ordered a replacement part from here, because the glass also fell and because it couldn't stay. I chose express delivery, stuff arrived within 1 week. I have made it difficult to disassemble the device because the back is glued together. It didn't want to come down, I tried all kinds of plastic tools they had given and what they were, but the glue was so strong that they all broke (I'll be curious to know how to put them together). I had to use a paper cutter, because it is sharp and goes into the gap. Unfortunately, the breakdown at the corner is slightly visible, but it must be as much trouble. Luckily the adhesive came out of the battery. (I will also have to order it from somewhere for rebuilding ). The main panel also came out of the house nicely. If we are already here, I removed the unwanted heat conductor paste and replaced it with quality Grizzly.

The display did not want to come out, it glued to the frame so strongly that it was impossible to remove it. I managed to do it in pieces, and I licked the remainder for half an hour. Worse, there is something new, no matter. Then I realized that the new one had no glue, and that the old one could not be removed because it was not an adhesive, but something like a very thin siloplast. I have injection needles and black silo, so I can make up. No loudspeaker lattice was added. I hope I can take the old one somehow to stay together. And here comes the black soup:

I plugged in the cable and turned the phone on (not screwed up with just a few screws to hold it). I have a picture, I started to calm down. Need to unlock it, but don't works, it don't feel my finger. Nowhere. If I remove the factory foil, either. I looked at the stuff in more detail. The photo already shows that something is wrong in the lower right corner of the display. The original has a large square-shaped Synaptics S3330 chip, the touch panel controller (like Mi 5). However, this is missing from the replacement device, with a much smaller IC of "S20A X705E24". I have no idea what it is, but it is also suspicious that a ribbon cable goes below the original and there is nothing there. But on the site of the seller there is also the ribbon cable in the pictures and it is highlighted as "Multi fingers touch chip". This may be some great big scam. However, if it have a Touch controller IC and something that is supposed to work in principle, then the Synaptics driver (kernel module) is loaded on Android. I suspect that then this IC should get the kernel module somewhere and should be loaded to work with a rooted device. But I also thought that I would try some other rom (AOSP, LineageOS) and see if it would go with it, but chances are that Recovery would not work with a USB mouse + keyboard. Maybe there are different hardware versions of Chinese and global versions? Because it is possible that Chinese (or eu) would work.

I wrote to the seller that the stuff wasn't working, he said I would remove the connectors with an alcoholic cloth (of course he didn't help). Until then, the time was up to 15 days, so I can't start a dispute. He asked me how he could help, I wrote to him that I didn't know but I needed another display in this device. I wrote to him that he might be able to return my money or send another display. He said that if I stood at 75% of the cost then he would send a new one. At first I would have gone into it, but now that I've examined this and it turned out, I wrote it and sent the picture as well. I don't expect anything good.

I found another seller that is already fitted with the frame (minimal more expensive), maybe there shouldn't be any fun with gluing, I could do better if this is not solved this way.

What do you think about this whole thing?
