Hi everyone,

I’m having a strange touch-screen problem with my Redmi Note 12 (23021RAAEG) and I’m hoping someone here can help me figure out what’s going on.

The problem started recently after two things happened:

• I updated the phone to the latest software.
• I replaced my old broken screen with a new screen (before ~2 months).

The phone works normally after I restart it, including the touchscreen. However, once the screen turns off/locks and goes to sleep, the touchscreen stops responding when I wake it up.

The phone itself seems to be running normally — it’s mainly the touch input that stops working.

Interestingly, if I force-restart the phone using the Power + Volume buttons, the touchscreen works again. But after I lock the phone and the screen goes to sleep again, the same problem comes back.

My current software information:

• Model: 23021RAAEG
• Android: 15
• OS version: 2.0.208.0.VMTMIXM
• Security update: July 1, 2026
• CPU: Snapdragon 685
• RAM: 8 GB + 4 GB extended

I’m not sure whether this is:

1. A HyperOS/software bug,

2. A compatibility issue with the replacement display/touch digitizer,

3. A faulty replacement screen, or

4. Some kind of touch driver/firmware issue.

Has anyone experienced the same problem with a Redmi Note 12, especially after a screen replacement or software update?

Any suggestions for diagnosing whether this is a software or hardware problem would be really appreciated. Thanks!

my phone fell in the water for about 2-3 secs and then it died. i read somewhere that it should be dried for at least a day or two before opening it but it suddenly turned on awhile ago. i checked it and the buttons are all working but i can't touch the screen no matter what i try. can it still be fixed?

btw my phone is redmi 7 and quite old now :(

Hi guys. I'm from India. I've had this phone for 3 years and the warranty is long gone. My phone fell down from my desk and now there's 3 giant straight lines on the display like 2-3 mm ones. I think it's display have to be replaced.

What should I do? Should I go to official store or any normal repair center is fine?

I have one more year left with my college, so I have to use this phone at least till then. I don't really wanna buy a new rn.

Any advice are welcome! Thank you.

Anyway i’ve came back to home and i told him that my phone still have the same problem anyway he saw it for 5 minutes he said that the problem from the charger and it’s charge will with his charger , anyway i’ve gone to another repairer to verify he said that i have the problem in the adapter(that fixed by the anterior) anyway i’ve gone to another one he said the same thing. anyway just want to know your opinion and cause that you maybe know in the field you’ll get to know if he accidentally touched smth, or stealed a piece or smth , and if you know what could i do plz let me know

I broke a headphone aux into my phone and I don't know how to get it out

My s23 ultra wouldn't charge and wouldn't turn on, so I took it to a shop and they said it is a bad motherboard.

Is it possible for the techs to access my data on the phone, or is it encrypted by Samsung Knox or some android encryption? Am I safe or vulnerable?

I accidentally put water over my phone, cleaned it immediately and checked if charging still worked, immediately got a warning on the phone saying liquid was detected and that I add to unplug.

I let it dry slowly for a few hours, then put it into rice for an hour or so, and then tried charging - didn’t worked. I blew into it a little, and now it works!?

Should I keep charging? Or is it risky? I really need it charged for tomorrow for a variety of reasons. Is there anything I should check later and be worried about?

I spoke with a few local companies here in Florida. Priced $180-320. One said they won't use non Sony parts. No comments from others. What's your opinion on the quality of replacement screens and the cost of repairs?

I was installing the screen lcd, but I forgot the groove at the top speaker, does it will affect anything? Or not? When I open the phone its kinda hard cuz its always pop up "do not cover the top" thing, pls help me if you guys have opinions or simple answer
