just tested it myself and lmao, none of the settings nor no matter how far you zoom in uses that lens. according to research i've done it seems to only activate if you're trying to shoot something more than 15 feet away. even still, that's strange.

Try live focus option. When you set this option the Lens will work.
[Xiaomi Redmi Note 7 Questions & Answers] ChaquiLois:
After the recent update MIUI Global 11.0.1.0(QFGMIXM), my phone charge duration extended. It takes almost 5-15 minutes to gain 1%. Any idea for the fix? I have wanted to revert the update but looking up the internet it requires root but my phone's not and will not to. I have also tried "troubleshoot" with the built-in Security app on this phone and also restarted the phone, still no benefit. I am annoyed with this, hoping for quick response for the fix. If you are looking for extra details and specs here it is:

Android Version: 10 QKQ1.190910.002

Android security patch level: 2020-07-05

RAM: 4.00 GB

ROM: 64.00 GB

Thank you! :o
[Xiaomi Redmi Note 7 Questions & Answers] Aures Batna:
this is the worst update i ever seen in this device

mine slow charging and drain battery fast

phone freeze

i think it is better to go back to the previous update
[Xiaomi Redmi Note 7 Questions & Answers] ChaquiLois:
Oof, I thought I was the only one. Is there any ways to revert without rooting?
[Xiaomi Redmi Note 7 Questions & Answers] nokuteshimo:
If you have the zip file with the miui rom, you need to unlock the bootloader and then you can use the MiFlash desktop tool to downgrade
[Xiaomi Redmi Note 7 Questions & Answers] ChaquiLois:
Where can I see those zip file? Where can I see the collections of old stock firmwares?
[Xiaomi Redmi Note 7 Questions & Answers] nokuteshimo:
I have no idea if there is something like that. unfortunately I've erased the previous zip files I had and the only one in my desktop at the moment is the one before the android 10 update wich is the V11.0.8.0.

I can provide it to you if you want.

Yes your data will be erased so make sure you have a backup.
[Xiaomi Redmi Note 7 Questions & Answers] ChaquiLois:
Already managed to revert on older versions. Thank you!

Hi. I'm wondering how I should compile aosp or lineageos. This device have different partitions like super partition which seems to have system files inside. Anyone have clue how to start with that?
[Redmi Note 8 Questions & Answers] /s/h/t:
Help me please.

My phone is in a bootloop and twrp cant mount /data. I tried formatting and changing file system but it all failed. I cant flash rom in MiFlash and it says "flash xbl error" or "FAILED (File is too large to download)"
[Redmi Note 8 Questions & Answers] kek-mex:
What did you do before the phone went into bootloop? Also did you format on TWRP via Wipe -> Format Data?
[Redmi Note 8 Questions & Answers] nneko904:
just format data and install rom through micro sd if your internal storage not working in twrp
[Redmi Note 8 Questions & Answers] /s/h/t:
first my phone went to edl then i paid someone to flash it with ufi and it failed while it is flashing user data (he refunded my money though) then my phone booted then i flashed twrp in fastboot. Yes I also did the formatting and failed:eek:

re install twrp(3.3.1-10) ,and vbmeta.img and reboot to twrp again
[Redmi Note 8 Questions & Answers] /s/h/t:
sadly it didn't work for me
[Redmi Note 8 Questions & Answers] /s/h/t:
I forgot to attach these.
[Redmi Note 8 Questions & Answers] kek-mex:
Alright. Im not that experienced with edl. Can you send picture of Wipe -> Advanced Wipe that we can see all of the partitions? Maybe also if you can send pictures of every partitions details by ticking them and then going to "Repair or Change File System" and taking screenshots? Don't know if this is gonna help, but it's worth a try.
[Redmi Note 8 Questions & Answers] /s/h/t:
Thanks for responding..
[Redmi Note 8 Questions & Answers] kek-mex:
Try changing the filesystem of /data to ext4, and then back to f2fs, and then rebooting into TWRP. I've had this problem before, and that worked for me.
[Redmi Note 8 Questions & Answers] /s/h/t:
It failed sadly.

[Android Q&A, Help & Troubleshooting] Volski_:
I'm learning how various OEM stores their dm-verity public key in such a way that it cannot be replaced by user owned public key even with the help of memory editing electronic programmers. According to Google's documentation on implementing dm-verity, it says the key is stored in /boot/verity_key.

verity_key verifies the vbmeta.img that contains root hash of the hashtree (and it's metadata like salt and offset) of other partitions. In this way integrity of every partition is verified.

Where exactly this key is stored which makes it tamper proof? Some of the answers I've been given is that it can be embedded in TPM or can be hardcoded in Extended Bootloader itself or somewhere in read only memory.
[Android Q&A, Help & Troubleshooting] Volski_:
Here's the answer I learned after some more research. /boot/verity_key which verifies vbmeta.img is itself signed by OEM private key. The OEM public key is hardcoded in bootloader at compilation time. The bootloader is verified by Extended bootloader and Extended bootloader is verified by Primary bootloader (PBL) which is burned on non-writable read only memory (also called BootROM). The chain of trust starts from PBL. But I don't think that all OEMs hardcode key in bootloader this way.
[Android Q&A, Help & Troubleshooting] Volski_:
You can simply extract public key by dumping bootloader partition in EDL mode. But even if you manage to extract it, there's not much you can do with that knowledge except to verify verity_key yourself.

Chain of trust here is the verification process of each stage in the boot process. A chain of trust is usually verified from the end point and goes up to the root node but in boot process it verifies the root node first and goes all the way down to the OS.

PBL is burned on CPU die (underlying circuitry on which CPU is mounted) which can be tampered with physical access in theory but not feasible enough in practise and not scalable either.

PBL verifies itself with Qualcomm's public key which is also hardcoded with PBL. Before PBL is verified, Qualcomm's public key is also verified with the hash stored in eFuse. This entire region is non-writable. This is why PBL is treated as root of trust.

Hey there,

is there a workaround to unlock the bootloader without the waiting time?

back there on my Redmi Note 5 there was a way.

Would love to do this again tommorow, when my Mi 10 arrives. So i can asap start with Xiaomi.eu rom.

(after Weekend i have no time to reinstall all on Phone thats why)
[Xiaomi Mi 10 Questions & Answers] krepsz:
No way!
[Oppo Realme 3 Guides, News, & Discussion] AviationTech:
Note:

-This will erase all your data so always keep a recovery backup

- This method only works on C.14 firmware version, so if you got PC then downgrade to C.14 using realme flash tool. Method for it is available in realme community. If no PC then flash custom ozip in custom recovery.

- we can only commit for all phh based GSI to boot.

Methods for flashing GSI:

•

C

ustom Recovery Method (still needs a bit use of Fastboot)

Note

: As this needs use of executing some Fastboot commands, you gotta use bugjaegar app in secondary device for Fastboot.

1) Flash Custom Recovery on your device through fastboot.

2) Now in fastboot, type the following command:

' fastboot --disable-verity --disable-verification flash boot boot.img ' (Credits to: @M.A.P)

3) now Copy your GSI Image (System.img) to your sd card.

4) Now reboot to Recovery via fastboot.

5) Press Install - > Install Image button -> Select the System.img file -> Select System Image-> Swipe to Flash.

6)) Now format data and then wipe cache & Dalvik cache.

5) now reboot to system, and GSI is flashed succesful :)

( If it boots to recovery then type this in Fastboot using bugjaegar app 'fastboot erase para' and 'fastboot reboot')

•

Fasboot Method (Using PC)

- install custom Recovery.

-> fastboots commands to execute:

- fastboot --disable-verity --disable-verification flash boot boot.img (Credits to: @M.A.P)

- fastboot erase system

- fastboot flash system xxxx.img (name of img instead of x)

- fastboot -w

- fastboot reboot

( If it boots to recovery then in Fastboot type 'fastboot erase para' and 'fastboot reboot')

Note

: if you guys want to revert to stock then can follow same procedure and use stock boot.img rather than the system img . It can be found in ozip file, extract it after converting it to zip file.

Special Thanks to all testers who tested and confirmed this method. :)

Here are some screenshots of GSI we booted:

[Samsung Galaxy Note 20 Ultra Questions & Answers] paulrgod:
Hey guys, received my Note 20 Ultra Mystic White today. Its stunning.. but disappointed to learn that it doesn't properly sit on the official wireless charging stand due to the camera bump. It does still appear to charge but I feel the way it sits on the bottom of the hump could damage it over time.

Bit of a silly oversight from Samsung as they're providing this charger as a free gift here in the UK..
[Samsung Galaxy Note 20 Ultra Questions & Answers] PseudoChris:
Doesn't sit flat, but it still fast-charges so it shouldn't be too much of an issue.

For those that use a case that raises the back to the camera bump, it can help to make even contact.
[Samsung Galaxy Note 20 Ultra Questions & Answers] apprentice:
I haven't seen this as a free gift, I have only seen the Wireless Duo gift for the Galaxy Watch 3, which is a 'lay down' wireless charger pad that would not have this issue. How have you managed to obtain the phone in the UK prior to release day? I am curious.

.
[Samsung Galaxy Note 20 Ultra Questions & Answers] paulrgod:
Nothing sinister... I'd preordered from Samsung.com on Saturday.. when ordering i'd picked the earliest slot for delivery which was on 21st with DPD... was surprised to see that my order was updated on Tuesday and then DPD updated to say will be delivered on Wednesday.. it arrived at 07:07, the earliest delivery I've ever had!

Would have preferred the duo charging pad though!
[Samsung Galaxy Note 20 Ultra Questions & Answers] marctronixx:
ive got the vertical stand i got for free with the note 10+ last year. im not having any issues with the phone sitting on the stand. i also use it on the duo charging pad with the watch.
[Samsung Galaxy Note 20 Ultra Questions & Answers] chetly968:
Lotsa people receiving their phones early. I got mine Tuesday morning surprisingly.
[Samsung Galaxy Note 20 Ultra Questions & Answers] apprentice:
Nice that you got it early. I got my Galaxy Watch 3 yesterday early from the official release date (direct from Samsung)

But what's odd, is everywhere else seemed to be offering the Galaxy Live Buds or the X-Box Controller and Game Pass as pre-order gifts. The buds being my choice as they are worth £180.

I ordered from EE and the phone arrives tomorrow.

.
[Samsung Galaxy Note 20 Ultra Questions & Answers] paulrgod:
Samsung.com had either the buds or a gaming pack which had the controller, wireless charging stand and 3 months gamepass. I chose this as have a set of Sony WF-1000XM3's. I guess the gaming pack in all is probably worth similar.

I've got terrible overheating and battery issues on my Note, may return it if doesnt improve over the next few days.
[Samsung Galaxy Note 20 Ultra Questions & Answers] apprentice:
I have been on XDA for over 15 years and I have lost count of how many people complain about overheating and battery consumption shortly after buying a new device, be it phone, tablet or smartwatch.

But you really need to give the device time to settle. There's a lot going on in the first hours and days, with apps being installed and synchronised, using your new shiny toy more than normal, taking time to optimise certain app and device settings that crop up, (that you probably had disabled on a previous device over time) and then the battery needs a few decent recharge cycles to get settled too.

I think you should give it a few more days and I reckon you'll be ok!

.
[Samsung Galaxy Note 20 Ultra Questions & Answers] paulrgod:
Thanks for the comment, 12 years around here myself :) I've had too many phones to list over this time, including pretty much every Note device since the Note 4 (i didn't pick up the 7). I've never seen anything like this... the battery i know should settle... but the heat is what is the most annoying causing the screen to be at low brightness every time i pick the bloody thing up, not once did the Note 10+ 5G ever do this even while gaming and such.. just typing this reply I'm guessing the device is now approaching 50c.. battery is at 85%, was taken off charge at 07:30, SOT 28 minutes...
[Samsung Galaxy Note 20 Ultra Questions & Answers] apprentice:
Firstly, I hope you didn't think I was being condescending in my answer! I am never quite sure on what level I am speaking to someone. So it's good to speak to a fellow veteran XDA member (see my sig for all the ridiculous amount of Sammy devices I have owned including all Note series)

I assume you have gone into the battery stats and looked at what is draining your battery. This week funny enough I was noticing a severe drain on my Note 10+ 5G and it wasn't for a couple of days I thought ... hmmm maybe I should check the battery consumption stats! It was LastPass that was doing it, really surprised as I don't even remember updating it. Google Play services is a regular culprit, especially on a new device. So maybe you should look at that first, because what you are describing clearly isn't normal and I haven't read any reports of this being common. Try rebooting in safe mode. Clearing cache in recovery mode.

You've probably tried all the above (I see you rolling your eyes!), I am just trying to cover everything that you might have missed. But I personally don't think the hardware is likely to be the cause. I hope you sort it and let us know what you found. My Note 20 Ultra arrives today, I will report back here if I have the same issues.

.
[Samsung Galaxy Note 20 Ultra Questions & Answers] paulrgod:
Nah didn't think that at all, just offering good advice. Yeah tried all the usual stuff clearing cache etc... didnt really noticed anything out of the ordinary on the battery page, the battery usage today is high from Samsung Internet, but I'd expect it to be the highest today as pretty much only used that today to browse a bit of news this morning, here and the note 20 reddit.. might try removing it and try Chrome for a while..

[Google Pixel 4 XL Questions & Answers] JWadle:
I am having connection issues with the Pixel 4 XL and the August WiFi SmartLock (4th gen). This lock uses both WiFI and Bluetooth to detect your proximity to home for the "auto unlock" feature.

The WiFI connectivity is OK, but the Bluetooth connection is very flaky. August support just offers their standard suggestions to clear the app cache/memory, switch BT off/on, restart the phone, power cycle and recalibrate the lock. This sometimes works for a while and then the BT connectivity begins to fail again.

There must be others with Pixel 4 and August Smartlock. Has anyone else had this problem and found a solution?
[Google Pixel 4 XL Questions & Answers] Spartan117H3:
So I have an August Smartlock 3rd gen with connect. My issue with the auto unlock is that if the phone hasn't been rebooted after a while, the auto unlock will trigger (based on location) but will hang forever trying to unlock the door, and eventually fail. I am able to connect to my lock and manually unlock the door without any issues while it's trying to auto unlock. My solution that I've found is that if you reboot your phone every 2-3 days or so, auto unlock should work flawlessly. My brother who has a Pixel 3 XL has the same issue and rebooting for him every so often works. It's honestly an annoying fix.

I went through a long email chain with August and they basically said they'd take note of it. I know clearing app data also works, but it's temporary and way more annoying to re-sign in and set up auto unlock than just rebooting the phone.

Let me know if just rebooting it every so often actually works for you as well.

[Razer Phone 2 Questions & Answers] Nadzeh:
Recently got this as a warranty replacement from Razer, when I lock the phone, sometimes it won't unlock. I'll press the power button, double tap screen, and nothing happens! I even noticed that my spotify was still playing in the background, but my screen stayed switched off. This has currently happened 4 times in the past 6 hours and I'm slightly worried I'll have to go through the RMA with Razer again, which takes 3-4 weeks :(

Any advice?
[Razer Phone 2 Questions & Answers] AlexBodewig:
I've had this problem a lot too ever since I got this phone. Rolling back to 8.1 fixed this and a lot of the problems this phone has. However, if you want to stay on 9.0 you're going to have to get used to this phone being a little rough. I personally unlocked the bootloader by following the instructions on Razer's website and put Arter97's kernel on it, which seems to help a lot but doesn't stop it from happening altogether. It's just one of the many quirks this phone has but not everyone gets for some reason.
