There's no notch for the proximity sensor, so it uses light from the display which is picked up by the camera if your phone is against your face.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Kawar3:
so i should see that light even if its not 2 my ear then?
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Kawar3:
just checked my recording and it flashs black sorry but its still next to the camera. maybe it is white but the video is not picking it up can that be a thing?
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] dajaco:
Sorry - this Jonboi guy isnt quite right - it doesnt use light from the display. There is a conventional infrared proximity sensor mounted beneath the display.

It shines directly through the OLED panel when you are in a phone call and your head is not within the correct distance to shut the screen off.

You can see it if you look closely on teardowns - I've highlighted it here on the note 10 teardown:

that's nice that its normal. it confuses me thought why samsung cant train there people right.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Kawar3:
anyone got a video what there sensor looks like by chance when they make a call?
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Kawar3:
please just kind of interested what your video shows if anyone can make me a video please
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] jonboi:
Thats a note 10, Totally different. Check before replying ;)

The flashing light to the right of the front camera IS the proximity sensor. If you don't believe me, call someone and watch it flash. Pop your finger over it and the display turns off.

Hi

I am on pie and want to downgrade to Nougat because of horrible battery life. Does anyone know if it is possible easily via LG UP & Uppercut and giving it the .kdz file or do I need to have the dev version of LG UP?

I am asking this because I read somewhere that pie will upgrade the policies and downgrading from pie won't be easy/possible. It would brick the phone. I know to downgrade from oreo is easy but does anyone have an idea of downgrading from pie?

There are some links which i am placing down here in case of reference.

[Downgrading from Pie BETA to Oreo](https://xdaforums.com/v20/help/lg-v20-f800l-how-to-downgrade-pie-beta-t3971971) (i am not on beta, i am on final release version or whatever it is called).

I tried checking my ARB using this code \*#\*#244773825625#\*#\* and my status is:

APPSBL(LK) 0 SBL1 0 TZ 0 RPM 0

I have F800K.
[LG V20 Questions & Answers] siheyo:
Yes you need the dev one to downgrade from pie.
[LG V20 Questions & Answers] G U C C I:
By "dev version", are you referring to the modified one that allows you to upgrade and downgrade with no issues? I believe it has the modified .dll.
[LG V20 Questions & Answers] awaisagha:
Can you please please point the dev version of LG UP post because I tried finding in the forum and found different ones.

And I believe the rest of the steps for the downgrade are similar as to upgrade, there is no complicated process involved. Am I right?
[LG V20 Questions & Answers] siheyo:
Try searching LGUP DUAL MODE. It should on be on the top of the list..

For me (f800l) the step sometimes a little bit not standard. But it could be different from your device. Try that lgup dual mode first.
[Redmi Note 8 Questions & Answers] Ahmad5544:
Hello guys I'm facing a issue that when I connect to external Bluetooth speaker then my wifi don't work in redmi note 8.is there any solution??
[Redmi Note 8 Questions & Answers] juzdu:
I bought my wife a Redmi Note 8T for xmas, and unfortunately it's been an absolute nightmare to operate ever since she received it. It works perfectly after a reboot, but after a few hours or perhaps half a day of use many of the apps on the phone refuse to open, they just display an all white screen or sometimes the logo of the app, but never open fully. You can close them, or press the home button to go back to something else but that app will not open unless you reboot the phone again.

I did multiple factory resets and re-set everything up but the problem always comes back. I ended up returning it to the retailer (I'm in Australia but the retailer was overseas), but they insist they couldn't re-create the problem, and refused to tell me if they were actually using the phone for a few hours before trying the apps...they seemed to be only ever trying it out after a reboot. I won't name the retailer but their customer service is extremely poor and I certainly won't be using them again. In the end I asked them to send the phone back to me, at which point they demanded $70 to return it as "there were no issues found". I paid it, got the phone back and then cancelled the charges on my credit card just to annoy them.

Anyway...I got the phone back a couple of days ago and set it up again from scratch, MIUI 11.0.5, added my wife's google account, installed half a dozen of her apps (FB Messenger, Whatsapp, Bring shopping etc)...she used the phone for about 2 hours then Messenger and Bring refused to open with the same problem. I can only imagine it's some kind of CPU or RAM issue. It's the 4gb/64gb model so it should be very capable of handling such a light load. Model M1308C3XG.

I figured I'd cut my losses so went and bought her the Mi 9 Lite from a local retailer yesterday morning and it's been working perfectly ever since. Cost twice as much as the 8T but at least I'm not copping an earful any more!

So...I have a new 8T that's has nothing to do....figured I might unlock the bootloader and try TWRP, see if it makes any difference. Did the unlock last night but it tells me I gotta wait 168 hours. Sigh. Anyone got any ideas in the meantime feel free to throw them my way.
[Redmi Note 8 Questions & Answers] Gokul726:
Hi Bro.

Me also facing this problem. I am using redmi note 8 (Indian verison)4/64GB variant

I faces the the same problem u mentioned above.

Me also reseted the mobile but the problem still occurs.

Also me unlocked the bootloader and installed the original fastboot flash ROM. But still the problem occurs.

I don't know how to solve this problem.

If you got some solutions suggest me....
[Redmi Note 8 Questions & Answers] juzdu:
Note 8T

I never did get it solved mate, but you know what's interesting is that I can't recreate the issue without a SIM inserted in the phone. I transferred the SIM into the new Mi 9 Lite and it's working fine, and I have been playing with the Note 8T without a SIM...the issue hasn't come back. So my guess is this is a fault with the GSM hardware in this model of phone...it might only happen if you're using a certain frequency which is why not everyone has the problem?

[OnePlus 7 Questions & Answers] DrRayThe2nd:
Today I was using my OnePlus 7 (OOS Beta 10, TWRP 3.3.1-70, Magisk 20.3) and I accidentally rebooted it to bootloader through the advanced reboot feature. Somehow, I know not how, this soft bricked the device. I could get to the unlocked bootloader warning screen but no further. I could also boot to TWRP and Fastboot still. I tried several different things to fix this, including disabling all Magisk Modules through TWRP, but to no avail. I also tried switching to slot A (I was previously on slot B), but I only booted to the OxygenOS logo and accompanying animation, which lasted 15 minutes or more. Impatient, I began trying several other methods (instead of making a backup :facepalm:). Long story short, I ended up wiping all the partitions (including Vendor and System) and I am stuck. I followed the guide here, which allowed me to boot to the OxygenOS logo and animation again, but no full OS boot. I have also reinstalled TWRP (3.3.1-79 now) which works as well, but try as I might I cannot get anything to boot besides that. I have tried installing the images from OnePlus' website, LineageOS 17.1, AOSiP, and custom kernels, but nothing works besides their own respective boot animations which loop forever.

And so, I have come to you, the best Android modding community I know of, to help me fix my problem. I can offer you no incentive besides my eternal gratitude.

Thanks in advance,

Michael

Edit: forgot to mention I use exclusively Linux so I cannot use the MSM tools. Sorry!
[OnePlus 7 Questions & Answers] spookcity138:
Download a Fastboot ROM and extract the images.zip. CD into that directory. Get your device into fastboot and manually flash them in Linux. The instructions for doing this are in that post. I needed to do this when I first got my OP7 as I also do not use Windoze. Worked without issue.

Edit:

I just saw that you said you tried this I guess. Give the first boot time. It takes awhile.
[OnePlus 7 Questions & Answers] DrRayThe2nd:
It has been 20 minutes and still no response. Should I wait longer?

Edit: 30 Minutes
[OnePlus 7 Questions & Answers] spookcity138:
Nope,it takes awhile, but not that long if I remember correctly. Sorry man, don't know what else to say. I've done this a couple of times. Once outta necessity and once just to test something. Worked for me both times, so IDK.

[OnePlus 7 Questions & Answers] spookcity138:

I don't run the unlocker
[Advantage X7500, MDA Ameo Upgrading] eaglesteve:
If you're in spl 1.2, that means you have already run the unlocker. This means you can flash any ROM that is compatible with spl1.2. However, you cannot flash ROMs that requires spl 3.5, and AP4.0 is a ROM that needs spl3.5.

Why not try out ROM's which are compatible with spl1.2 instead?

I've been a longtime rooter of cell phones, ever since the LG Ally. This particular phone doesn't seem to beg to be rooted, in my honest opinion.

I never get US Carrier phones because they hate root and will try anyway to try disable or remove something so you cant do it, because they want you to use as is and they sucks with optimizations for new OS and slows down phone. This is why I get the US Unlocked model when LG releases it but sadly the V50 did not get a US Unlocked so Ill get the V60 if it does.

[LG V40 Questions & Answers] KouaV1:
Theres an international unlocked and an US unlocked model. You can tell by going into about phone and looking what model you have. Your phone was probably sim unlocked if it has verizon apps as an pre installed app. The international unlocked V40 variant should be V405EBW and the US unlocked variant is the V405QA7

So I selected Installation on the first page. And after some codes passing, I installed it in my D drive and selected 'Do not re-format' And installed bootloader GRUB. And clicked Yes on the first picture.

My question is that how can I boot bliss os without the boot usb. If I try to boot bliss os without usb stick, I get this error(second pic) and doesn't boot Bliss os.

Every time I want to boot Bliss OS, I have to install it all over again. Any help is appreciated.

[P3300, MDA Compact III ROM Development] Andre1210:
I have a problem that applications that run in background are sometimes killed automatically.

When an application is running, I start another application and after closing the second application the first application is closed too.

For example:

OZI-Explorer is running. I start the camera to take a picture. While the camera is running I can see that the GPS-LED (OZI uses GPS) stops flashing. So OZI Explorer was killed in background. After closing the camera OZI-Explorer is gone.

Sometimes I only run a game like vexed. S2U comes up to lock the screen. After Unlock vexed is closed.

Program memory is not the problem. I have more than 13M sometimes near 20M when more than 1 application is running and the problem occurs.

I found out 2 things:

- Direct after soft reset the problem does not occur, but after a while of

usage.

- all WM6.1 roms with a higher build number than Artemis touch 4.02 have this problem.

In 4.02 or lower the problem never occurs.

Does anyone have this problem too?

[P3300, MDA Compact III ROM Development] shoonari:

Keep an eye on free ram! even 13 mb is not enough for smooth running. especially for gps.

With Artemis Touch 4.02 I had less program memory than now, but the problem NEVER occured.

I use sashimi - so on every ROM I use, the installed programs are the same.

Sometimes the problem occurs with 20M free program memory.

I have no idea anymore.

I like the new rom from Tom (Oops) cause it's faster than 4.02, but I think I've to return to 4.02.

[P3300, MDA Compact III ROM Development] Andre1210:
Problem solved

The problem is solved. It's really the terrible HTC Task manager.

If Autokill is enabled the task manager kills background applications if the free memory is under 9MB.

The pagepool is not the Problem cause Vanilla has the smallest PP size (5MB) - only indirect cause the free memory could be higher ;-).

I watched that sometimes a windows thread uses for only a very few seconds much memory. The free program menory fells from 18 suddenly to 9MB and returns immediately to 18MB. These few seconds are enough for the taskmanager to kill applications, but you don't realize that the memory was low.

After disabling this feature the system runs optimal.
