large, abrupt jump when switching camera modules

Recently I have bought used Xiaomi 15 and noticed this behaviour. I have tried: flashing first HyperOs 2 version, flashing latest HyperOs 3, camera calibration in Engineer Menu. My current smartphone is Xiaomi 13, and it has no issues like that.

Looks like the telephoto camera is not centered correctly in it's seat, but repair technicians in my town can't help with it. Is it possible to remotely calibrate telephoto camera using some advanced paid Xiaomi tools? What else can I do to fix this issue? Please, help.

I had Xiaomi Redmi Note 11 about 7 years ago and i didnt really like it, because it started lagging and my dad is saying that android still lags after about 2 years and i dont want that.

[Discussion] [Guide] How to Unlock Bootloader on HyperOS device Officially and Trick how to get granted access via Xiaomi Community App.

As we know, on HyperOS based Xiaomi phone unlocking bootloader is quite challenging. Because now you need a Xiaomi account that has granted UBL access via Xiaomi Community App. And the quota is limited for each day. Many user who attempt to unlock bootloader having hard time when requesting UBL access via Xiaomi Community App. Today i'm giving tips on how to get UBL access much easier.

Tested on Xiaomi 15 (dada) HyperOS 3 :

  1. You need an Xiaomi Account that has been registered atleast 30 days.

  2. Login your Xiaomi account to your device in Settings.

  3. Open Xiaomi Community App (if you don't have, you can download it from playstore) and login with the same account.

  4. On the app, tap "Me" on bottom right corner and go to settings. Then change region to Global. Now you should see "Unlock Bootloader" option in "Me" page.

  5. You get yourself ready on the UBL permission page and when the time is 23:59:59 GMT+8 you spam the Apply for Unlocking Button until around 00:01:00 GMT+8. (You can use floating clock from developer option to keep eye on the time).

  6. I've found that Xiaomi Community App is buggy app. So there's a bug that when you're trying to request UBL the app will say "Application quota reached try again.....". But there's a chance that actually your account has already granted the UBL access. It's just the app has bug saying that you need to try next day.

  7. So next step is, just try to bind your mi account again inside the developer option. And see if it still no UBL access or your account actually got the access.

  8. On PC download Mi Unlock Tool and install Fastboot USB Driver.

  9. Open Miunlock tool, then Login with the same account.

  10. Now go to fastboot mode (Restart then hold volume down button OR turn off your phone and then hold Power and Volume down button simultaneously).

  11. After your phone is in fastboot mode then connect your phone to your PC. And then press "Unlock" button.

  12. It will start the UBL process. When the Mi unlock progress have reached 99% it will tell you if it successfully UBL or you need to wait for sometimes in my case i need to wait 58 Hours.

  13. If you need to wait for sometime, you can use your phone again normally while waiting the count down your data is not yet wiped. But don't re-bind or logout your Xiaomi Account from your phone. Otherwise the timer would reset and you need to wait again.

If you have any question, just drop it in Discussion Section.

New User Rant: Disappointing and deal-breaking battery drain experience on Xiaomi 15

I recently bought a pre-owned Xiaomi 15 (Chinese ROM) with 97% battery health. I am from Bangladesh; even a fresh-condition used Xiaomi 15 is expensive for me, so coming from my 2-year-old potato Galaxy M35 to the Mi 15 was a big leap, with even bigger excitement.

Anyway, the battery drain I have been facing since buying wasn’t something I even thought of. It is shocking. I do not game. All my phone activity is taking photos, watching YouTube, using Messenger and Instagram, and occasionally using maps when I am out and about. On top of that, I am not even a whole day doom scroller; I have an active life. So my phone use is not constant. Yet I struggle to get through the day on one charge.

My 2-year-old Galaxy M35 is still doing a better job than this far newer Xiaomi 15 phone. I have already been tweaking the options like: battery restrictions, autostarts, battery protection, and every other setting to check and minimize apps unnecessarily draining the battery. Yet, no improvement. 

My point is that, if I have to painstakingly tweak every possible setting just so that the phone battery doesn’t kill itself every 12 hours, while my old phone has been doing an excellent backup job without me ever going through all that anxious manual labour, then it could only mean that the software is not doing its job to keep the battery running normally. Tbh, compared to the OneUI on my M35, this HyperOS has been so far really a crappy downgrade. It's such a shame that I have to replace such a snappy-performing phone with a great-looking camera if this battery issue is not fixed.

(TL;DR - Just came off of a 2-year-old Galaxy M35 and this only 5-months used Xiaomi 15 is already giving noticeably worse battery backup with no gaming, just using camera, music, YouTube, social media, 5G turned off. So I blame the sloppy software for this battery disaster. Does Xiaomi have any past history of fixing this specific issue with a software update? )

[Question] Why isn't my Xiaomi 15t updating?

I bought it on May 18, 2026, from the Entel carrier on a 12-month payment plan, but when I try to update, it says it's not available. I've been trying, but it's now August and the update still hasn't arrived. Can anyone help me with this? I really want to update to HyperOS 3 (Xiaomi 15T).

Who can help me update, or do I need to install a custom ROM?

The reason of battery swelling

Guys, the Mi15's back cover tends to come loose over time, not because the battery is bulging—well, primarily because the Xiaomi is such idiots that they replaced the Mi14 glass cover, which had a convex back cover, with a completely flat. That's why there's no room under the back cover for wireless charging, and it puts pressure on the back cover right near the power button in a straight line to the opposite side, causing the back cover to bend and bulge. I solved this problem this way: I removed the factory adhesive and applied the back cover to a transparent Relife RL-035A. I used a lot of clamps and placed the phone on the charger to keep it warm and allow the adhesive to dry better. Ultimately, I restored the water resistance even better than before the re-gluing, and the back cover no longer bulges. Incidentally, the battery didn't bulge, as expected.

Xioami 15 glass screen protector with working fingerprint scanner

So one day I was randomly searching for a screen protector for my phone , and I stumbled upon a listing with claimed fingerprint functionality just for 105 . To say the least I was bummed when I had to buy 3 just to get it ordered , but yesterday after receiving the package I was happy as it came packaged in a plastic box with many supplies you need to put the glass on . And the glass works as advised , because it's thin the fingerprint works well and I was able to get a professional install as my first time installing it . Putting the screenshot of the glass if anyone wants to buy one .

Xiaomi 15 matte screen protector

Hi everyone,

I'm looking for a good matte screen protector for my Xiaomi 15 and would love some recommendations from fellow owners.

A few key details:

Location: Must be available to order in France / EU (Amazon.fr, AliExpress, etc.).

Fingerprint Sensor: Needs to work smoothly with the ultrasonic fingerprint scanner without major accuracy/speed hits.

Ease of Application: Looking for something relatively easy to align and install without trapped dust or bubbles (hydrogel or easy-install film/glass).

If you’re using a matte protector on your Xiaomi 15 that fits the bill, please share the brand or link. Thanks in advance!
