[Xiaomi Mi A2 / 6X Questions & Answers] Tyzmon:
Hello,

a few days ago I bought a new Xiaomi A2 4GB/32GB.

Mechanically everything is fine, but two things seem odd to me:

There is a, albeit quiet, noise coming from the display. In the notebookcheck.com review of the phone they say it uses PWM for brightness regulation at about 1100 Hertz, which is almost the frequency of the noise. It is not always there, but most of the time. I can hear it from about 15 centimeters from the phone.

The other thing is the vibration motor. While my former Redmi Note 5 produces a low hum, the motor in the a2 makes a much brighter sound. The problem I encountered is that it sounds like the device, or something in it, is even vibrating to the motor, which makes a hissing noise every time the motor engages.

Has anybody experienced similar issues with the A2? None of these are apparent on my Note 5.

Thank you for reading and your answers :o
[Xiaomi Mi A2 / 6X Questions & Answers] Benjamin_L:
Either you are very sensitive to those frequencies or your phone is broken as I can't hear any 1 kHz noise from the display
[Xiaomi Mi A2 / 6X Questions & Answers] selvarajrajkanna:
Maybe your phone is haunted ?
[Xiaomi Mi A2 / 6X Questions & Answers] krishdemperor:
I am not sure about the noise from the phone, but I can feel the vibrator extra hiss than regular, Its coming from the camera side, when I try to place the phone on surface, on contact, the camera position side make kind of rattling noise, where some of the parts are loose or not fitted properly.

Hi i had battery problem for every full charged sometimes battery drop normal for 1minute 1% down. But not always, sometimes i can use 30min heavy like messaging,yt videos,and not dropping down any percent. But when i lock phone and stand by for 5minutes,i unlocked phone and see 92% where percent gone? Battery problem? My phone 3 months old. Baterry too.
[Xperia Z3 Q&A, Help & Troubleshooting] thelegacy2010:
I think you need to replace your battery since the device is already 3 to 4 years old. Replace it with Sony OEM battery.

I had a similar problem few months back then I replaced it and everything's fine now.
[Xperia Z3 Q&A, Help & Troubleshooting] myka_1997:
Hey , my phone 4 months just i buy new , i think go to service center and say battery problem , and changed it, but i had a reply consultant, JUST REPLACE WHEN BATTERY IS BAD , NO CHANGE AS GOOD , I want changed battery because confused and not last for 1 day of single charged, my battery died at 2 hours of full brightness and 4g is always on..

-----------

YESTERDAY WHEN I UNPLUGGED after full charged 100% was 2-3 hours stand by and not discharging after i set up full brightness and using for snapchat, and normally discharged for every 1 percent. :) looks good. after reboot 60% percent i see 57% AND TODAY i unplugged for full charged just locked phone and see what battery doing, i unlocked after 5-10min and see 97%
[Xperia Z3 Q&A, Help & Troubleshooting] thelegacy2010:
Sony stopped the Z3 production years ago. This is a already old device so the battery its having will certainly be an old one.

Which ROM are you using? stock Sony ROM? Or a custom ROM?

Download this app called AccuBattery. Use it for like 2 to 3 days go know your battery's actual capacity and let me know.

Your battery is either draining because some apps are draining your battery massively or outdated battery. There shouldn't be so much loss like in 5 to 10 mins like how you did. :(

Check your battery stats from that AccuBattery app and if it's bad you'll have to replace it. :good:

I get 4 to 5 hours of screen on time with 70% brightness.

[Xiaomi Poco F1 Questions & Answers] mili2110:
Since the Mi 8 doesnt have L1, I would guess the Poco F1 doesnt have it either.
[Xiaomi Poco F1 Questions & Answers] rahulkamma14:
I read somewhere that it has level 3 support. Means you can play videos to max 480p. In Netflix and Amazon prime. Even mi8 has L3

You think this would be never be changed? i use a lot netflix, so this may change for me the option to buy this phone...
[Xiaomi Poco F1 Questions & Answers] shailendra1993:
1. It's L3 support i.e. only 540P.

2.No it's can't be upgraded because changing Widevine requires a physical connection with a authenticated computer, if Xiaomi does provides that, it will cost them a lot, they won't do anything for this.

[Xiaomi Poco F1 Questions & Answers] Crescendo Xenomorph:
https://www.androidauthority.com/widevine-explained-821935/

Perhaps one of the most important points to note about Widevine is that it doesn’t charge a license fee in order to implement its protection technology. So there’s no financial reason why smartphones like the OnePlus 5T are missing out.

Instead, hardware manufacturers only need to pass a certification process. This includes the completion of various legal agreements, implementation of some software libraries, and client integration testing to verify support, among other steps. Apparently this process is designed to be streamlined for easy adoption, and all chipsets used for Android smartphones support the necessarily technologies, so it’s only likely that manufacturer oversight or lack of testing time is to blame if smartphones aren’t compatible.
[Xiaomi Poco F1 Questions & Answers] shailendra1993:
Yea, I read the article too. I don't think that any of the Xiaomi phones in India has the certification, even the Android One phones by Xiaomi don't have it. There we have Xiaomi running from legal documentations, Well, what can you expect from a Chinese enterprise?

---------- Post added at 09:39 AM ---------- Previous post was at 09:35 AM ----------

And you believe them? it has never happened before, it is not gonna happen now, these certifications are not provided over the air due to security risks. They are just stalling.
[Xiaomi Poco F1 Questions & Answers] rahulkamma14:
But Sony Xperia Xz2 got the update via OTA. You can check for yourself
[Xiaomi Poco F1 Questions & Answers] shailendra1993:
Xperia XZ2 already had the required device-unique secret key in the TrustZone for Widevine L1 support, i.e. their Stock Firmware already had L1 certification. Do you really think Sony would ship a Flagship without L1?

Only the older P beta previews didn't have the L1 support, it was later added in the July build.

I don't think Poco F1 was shipped with the required secret key, and that's something that can't be "fixed" with an OTA update.

Source: A comment made on XDA News about the same issue.
[Xiaomi Poco F1 Questions & Answers] rahulkamma14:
We'll see. Cause they told us that they are working on it.
[Xiaomi Poco F1 Questions & Answers] shailendra1993:
They are just stalling.

They also said that Bleeding issue is not bleeding issue but a gradient feature that will be solved in MIUI10

They also said that multitouch issue is solved in next update.

They said a lot of things.

Did they adhere to their promise?

one thing for sure is China doesn't have Netflix/Amazon/you-name-it, that's why they doesn't care about Widevine L1...

[Huawei P20 Pro Questions & Answers] goldenr:
From yesterday Huawei started rolling out GPU turbo update (for European models) which comes with game suite.

Today I got a .131 update, where changelog said that it has only security updates. But I noticed the game suite has been added with game acceleration (not GPU turbo). On FF it shows there is .132 update coming with august security patch (wonder if that is GPU Turbo or not)

None of that makes any sense. (why didn't they put GPU turbo together with game suite, because that's what the other models are receiving) I assume the GPU turbo update will come end of Sep for UK models

[Xiaomi Mi 8 Guides, News, & Discussion] gregorypappas:
So i have to download this rom copy to phone and install via updater?
[Xiaomi Mi 8 Guides, News, & Discussion] rodfrang:
No, you have to install the ROM with twrp.
[Xiaomi Mi 8 Guides, News, & Discussion] achickennugget:
For everyone who is wondering if you can upgrade from previous Global beta 8.8.7: Yes you can, without losing settings/data.

Steps:

1. Perform fastboot flash recovery (twrp3.2.3-0806)

2. Boot into TWRP

3. Flash the ROM as you would with any other ROMS (Wipe cache/dalvik)

4. Flash Magisk/ DM-Verity disabler (Optional)

5. Reboot. Phone should not take more than 5 minutes to get into home screen (Otherwise you did something wrongly)

*.tgz file - Fastboot file (Requires Mi Flash)

.zip file - Recovery file (Any recovery i.e. TWRP)

PS. China Mi 8 variants (Do not attempt to relock bootloader OR to downgrade to Miui 9 as it will brick)
[Xiaomi Mi 8 Guides, News, & Discussion] gregorypappas:
If i dont update and stay at 8.8.7 for now cause i have no problems i will get any ota update later or i will stay for ever at 8.8.7 global beta?

i try install the twrp3.2.3-0806 but every time i give adb reboot recovery it starts at mi recovery 3..
[Xiaomi Mi 8 Guides, News, & Discussion] achickennugget:
When open beta is out, I am sure you will be able to download the recovery version and flash touring updater, hence not a problem.

Reason mi recover keeps flashing over your twrp:

You must flash Force-encryption/DM-Verity(this) Disabler right after flashing your ROM. DM-Verity is a recovery checker built into the ROM that will overwrite and any recovery that is not miui recovery. The DM-Verity Disabler zip file scroll down and download from: https://zackptg5.com/android.php

Flashed 8..8.30 with TWRP over 8.8.21. Works generally fine, just the Permissions menu keeps crashing when I tap on it in the system options. Same goes for the battery chart under Battery & Runtime. Probably can be fixed with a factory reset, but I'm not in the mood to set up the phone again ;)

PS. install first Magisk 16.0 and then dm verity disabler first, reboot into recovery and install universal safety net fixer thirdly gives you a Google certified phone. Worked for me perfectly :)

[Moto G5 Plus Questions & Answers] luizlee86:
Hi! I have the US 4GB 64GB version of Moto G5 Plus which is not avaiable here in Brazil.

Gonna try to be clear... but sorry for my bad english...

The fact is that I was on debloated Nougat (bootloader unlocked and rooted) and was experiencing very poor signal in several situations... the most notable was when I was on the subway and since this phone is veeeeery popular here I could see a lot of people using this phone, browsing, facebook, instagram etc. but, even though the network signal in status bar was full or almost full for me, it was like I had no data at all..

I then upgraded to Oreo Soak Test #3 yesterday and today I noticed that now in the subway, I have no data at all, there is no 4g/3g symbol next to the signal symbol...

So the question... what affects the phone signal? What can I do to solve this issue?

Oh, my carrier is maybe the best in my region when it comes to coverage

Thanks in advance!
