Camera LED Flashlight power intensity really low after porting a rom

hi everyone! I recently ported a 5.1.1 version to my my6592 phone star g9000. The camera was not working in the beginning but i managed to fix it, but the intensity of the flash is really really low. I tried some things to increase the power of it through build.prop but didn't work. I used to have the same issue when i installed some roms before this one with FlashTool, but i just changed the camera drivers with SP MTD tool and it was fixing the problem. I can't use sp mtd tool now because it will reformat my whole emmc partition. Any ideas on how to fix this? thanks in advance!

Hye. Need someone expert on this. My device got problem on sounds. This happens when i plug in 3.5mm audio jack to my speaker. Suddenly my device reboot loop on mi logo.

Try going back to official miui
Already flash stock global rom using miFlash with no luck. Btw, thanks.

[FIXED] In call earpeace, Speaker, fingerprint not working after installing Android P

Hello guys,
I am in big trouble after installing Android P DP4. After 1.5 to 2 days of using android P dp4 my earpeace, main speaker and fingerprint stopped working. So, I went back to Oreo AOSCP. same problem there.
So I decided to flash MIUI and flashed MIUI 10 developer version all partitions from fastboot. Same problem there. No Fingerprint, no both speakers.
Plus when I connect phone (MIUI) in PC, It says Pixel XL, Why it is showing Pixel XL after flashing all the partitions??
Now you will say it is hardware problem.
But,
Fingerprint worked when registering while setup in android P. but not working to unlock phone.
Main speaker working when call comes. but not working while playing music (both custom rom and MIUI)
In call earpeace not working anywhere. But I am sure it's software problem. (tried flashing in call fix from GSI thread)
Any solution?
Fix: Automatically fixed.

Ulefone Armor 6e touch screen not working after rom update.

I tried to root my Ulefone Armor 6e but used wrong bootloader (I took from Armor 6 by mistake) so I stuck with bootloop with just fastboot working (no recovery).
After this I flashed correct rom GQ3071RF3_EEA_20190509_V08(EU version) from Ulefone website. Now it boots correctly to recovery and android but touch screen is not working. Maybe I didnt flash it entirely correct.
I flashed boot, recovery, vendor and system. Did I miss something?
Does anyone could share OTA update Armor_6E_RF3_EEA_V01_20190713-2105 (which I had installed before) so I could reflash?
Same screwup and resulting problem, but on a 6S.
Anyone know how to fix?
hello can you provide me an email to send you the ROM
Ive noticed it's no issue with rom but probably calibration data was deleted during the update. After reflashing NVRAM from another phone red text tee key google key disappeared but the screen is still not working.
If anyone knows where is stored touchscreen calibration data I would really appreciate

Software Issues

I have a redmi note 9s (the topic is about this device). After testing a port of Android 13 or beta 2 I ran out of sensors and the audio was cut off, they told me to pass the stock via mi flash to solve the same, the stock doesn't boot on my phone anymore, it just stays on the Redmi logo, but I enter in fastboot, in recovery stock and after passing the custom recovery I enter the custom recovery too. With that I can pass some custom to use the cell phone, it comes back with the sensor bug and audio cut or no audio, I wipe several times, format data, I pass a zip called "clean.zip" the firmware and even then solve the sensors and audio. I'm afraid to keep changing roms now, but it's complicated to stay in just one rom, and when Android 13 comes out I'm stuck on 12, apart from that I can't go to stock anymore. Anyone had a similar problem? do you know any solution? Thank you very much for everyone's help in advance, Best Regards MurilloAssF
