[Q] Camera problem, what do you think

hey guys im new on this wp8 forum (old android user) i bought an ativ S from a dude i met once... i knew this had a problem with the camera, i just realized that the back camera is the only one with the problem, ive been reading posts and i tried everything to make it work, but i allways got the same, it doesnt start correctly, i press the camera button or use the camera icon, but its allways the same, the 1st start its like it close so quickly at the 2nd try it keep the screen black, i only see the icons, and an arrow to swipe and see the pics i toke (with the front camera and a 3rd party app) but it close in around 10 seconds... idk what to do... i tought maybe was something about and update (a past one) but few days ago i got an update (not grd2, a minor one) but nothing... i still have the problem... what do you guys think... its a hardware problem or maybe software?... ireally love this cellphone and i dont wanna stop using it

If third-party apps can use the main (rear) camera, then it's not a hardware problem; you could try hard-resetting the phone and seeing if that helps.
If even third-party apps can't use the rear camera, it's either a hardware or firmware problem. Since this is the first I've heard of you particular issue, and since an update didn't fix it, that suggests a hardware problem (it *could* be firmware if you have some weird non-stock firmware on there; what version info do you have in settings->about->more info?). If it's a hardware problem, replacing the phone (or just living with the meh but usable front-facing camera, I guess) is your only real option.

thank you for your answer, =)
uhmmm, as you say i only can use the back camera with an 3rd party app, because when i try to open the pre installed camera app it close...and the camera icons appera in a gray color... except the arrow to see the taken pics, that appear in white...
i discovered some other ppl who had the same problem, :/
oh oh ok. my telephone info is...
Os version: 8.0.10327.77
firmware:2212.13.6.1
hadware: 15.3.1.0
trans soft: 2212.13.6.1
trans hardw: 0.0.0.0
(i actually dont know how to translate this from spanish): 13.04.19.21
SOC chip version: 1.5.32
this is the info i got, before uodating it, the number were almost the same :/
mmmm i remeber when the update was almost ending it was like 1/5 complete... then 2/5 complete... and after that the phone started...what i mean is that there was no 3/5 4/5 or 5/5 steps...
man so you are telling me i wouldnt be abble to replace just the camera, if is a hardware problem??? oh jesus =( i really love this cellphone i dont wanna lose it =(
thank you for your answer my friend =)

First of all: you have GDR2 and the most current firmware that I know of for the SGH-T899M. The line you couldn't translate is "bootloader" (the code that starts, or "boot-straps", the operating system). Your version numbers are identical to mine.
My rear camera works fine, though. Since third-party apps also work, you either have bad firmware somehow (doubtful, especially after the update) or there's something wrong with the Camera app on the phone (more likely). Unfortunately, the only way I know of to fix the latter problem is to re-install the OS (which a hard reset will, or at least should, do).
Replacing just one component, like the camera, is very difficult on a compact device like a modern smartphone. It might be possible, but the cost might not be worth it. On the other hand, if the phone is still under warranty, you should be able to replace for free.

GDR2??? are you sure my friend?? ive reading and that update come with the Radio app, some camera features and other... but nothing :/ i just got some options in settings and that was all, i even cant download or instal Ativ beam (i dont find it on the store, and when i try to do a manual install it say that is not compatible) and i heard that app is only for the last update
my cellphone is canadian i think, because the company is ROGERS, and i live in peru, so i cant use the warranty or something
i will try to save some of my info, and i will do another hard reset
Do you think there would be a tool for a diagnosis?? i mean conecting my cellphone to a PC in DOWNLOAD MODE or something???
i swear i wont rest till i fix it :'(
again, thank you very much for your time.
P.D: let me show you what the camera looks like for a while

Yes, build 10327.77 is GDR2. Your phone is a SGH-T899M, same as mine; GDR2, along with an interim update ("Amber" maybe?) and a Samsung firmware update, was pushed out to all Canadian SGH-T899M handsets (including those operating in other countries, like yours and mine) a couple days ago.
ATIV Beam installs fine for me; it's probably a region lock and not a matter of device compatibility.
Samsung is reported to have cheapened out on the radio chips for the SGH-T899M, and not included the one needed for FM.
Data Sense (assuming your carrier offers it) is supposedly included, but due to <REDACTED>-up update process, you have to hard-reset to use it (how the *HELL* did that make it through testing? That's supposed to be exactly the sort of BS that those months-long and tens or hundreds of thousands of dollars of testing per-update are supposed to find! Bloody incompetents...)
There's an app called Diagnosis embedded in your phone's firmware; you can install and launch it by typing either ##634# or ##3424# (MFG or DIAG) into the phone's dialer. Check the relevant thread here about dialer codes and diagnosis apps for some examples of things you can do with it (among other things, test the cameras). However, if the camera is working in third-party apps, I doubt that test will find anything. As I said, that indicates a software problem. Hard reset is the only really likely fix for that, if you can't get Samsung to service it. Flashing a stock ROM would probably work too, but I don't know that we have either the ROM nor the flashing tool needed for doing that.

incompetents!!! hell yeah!!! !
my friend are you some kind of wizard or something??, while you were writting it, i was doing a hard reset, and now i have data sense... and oh thats why i cant have ativ beam (NFS in WP devices suxs ass hell, i cant send anything) and... Doesnt have a FM radio???!!! SAMSUNG are you serious?!?!?!?...
i did the ##364# and i got the diagnosis item, thats how i noticed that the front cam worked fine and the "megacam" (front one) doesnt work... (i used the *#0*# code) plus the camera LED doesnt work either
oh well , after the hard reset i just got all my data lost n_n; , but you know... the frontcamera still doesnt work... tell me truth im already FU*beeeep*d ,am i?
i really want to believe that this have a solution...at least a non invasive solution...

I actually have the same issue. Before installing the updates from MS and Samsung the camera worked perfectly. When I updated my phone and did the hard reset, the camera behaves like you say, either a black screen or back to home screen. I called Samsung and they say it is most likely that the update did not install correctly. Though they talk rubbish sometimes as they also told me to update through zune........that doesn't even support WP8..
So flashing a stock rom "might" fix the issue. :fingers-crossed:

The rom was changed before I got the phone, Can I still use it properly? (read Desc.)

Ok, so I bought the ROG Phone 2 on AliExpress a few weeks ago on Black Friday because I really needed a new phone. After reviewing the page details I found out that the seller puts the global rom on himself because it comes by default with the Chinese rom. Will this still work for banking apps and OTA updates? Can I make it work somehow? Had I known in advance that it wouldn't be the Real global version I wouldn't have bought it, but since I've waited so long to get it, I'd just assume make it work myself, rather than go through the whole hassle to return it. I don't know much about custom rom's and what is / isn't possible, so I am at a loss as to what to do, or how I can check what kind of phone it is when I get it. Any help would be much appreciated so thanks in advance!
Here is the page where i bought it, because it has some more information on specifics: "aliexpress.com/item/4000106113494.html?spm=a2g0s.12269583.0.0.5fd61d0e5SUkH5"
Also side question, since the seller changed the rom himself should I be possibly concerned with keylogger or anything?

1. I shouldn't worry too much about keyloggers etc. but if you are, just run a good virus scanner when you get the device...
2. With regard to banking apps, they mainly have issues with being rooted... which you won't be.
3. Regarding OTA's, assuming the fingerprint has been changed, you can see this thread for an app that allows updates to be enabled, providing you aren't rooted or anything.
But, if they haven't changed the fingerprint (you can check using device info HW under 'system') then you'll need to follow one of the guides on the forum to change it yourself... here's one... change fingerprint

Question Wi-Fi calling disconnections

Just got my first Xiaomi device and really enjoying it, however Wi-Fi calling (on EE in the UK) disconnects every 50 minutes without fail (call with drop). I can watch in realtime the VPN connection on port 4500 in my router diagnostics and see it strike up a new connection a few seconds after 50 minutes.
I think this may be to do with the carrier settings being incorrect. Under IwlanSettings there is a esp_timeout setting (from another device that works on EE fine) which is set to 3000 seconds = 50 minutes. I think the esp_timeout on the Xiaomi may be set to a higher value, typically the esp is refreshed around 90 seconds before the end of the timeout. I assume the operator times out at 3000 because my end hasn't refreshed it as it is thinking it has more time.
To test this theory, how can I edit these settings. On another device there is a Iwlansetting widget I can add via Nova, but this doesn't exist on the Xiaomi. Can I change these settings via adb?
What is the best way to feed this back to Xiaomi?
Thanks for any help or pointers.

Had an update to 12.5.16 this morning and the bug is still there, with Wi-Fi calling on EE dropping every 50 minutes exactly.
I've sent logs and feed back using the app on the phone, no response almost a month later. Do they even look at that feedback?
My first go with an Xiaomi device, they might be good value devices and well built, but the aftersales support seems non-existent.

England using the EEA ROM that came with it (RKDEUXM). They tend to stagger updates so we may not all get the update at the same time. Typically no useful release notes, so no idea what has been fixed, and I see no differences except for the System Updater now being white when it should be a black background (as dark mode is on). So no fix for a fundamental issue of calls dropping, but I found a UI bug almost immediately, so this is Xiaomi supporting their devices, doesn't bode well.
It reports it has Android security update 2021-11-01

Not something I've ever needed so not entirely sure, but I don't think so as it just uses the standard Google Phone app and no options in that for call recording that I can see.

There is NO call recording on EEA. Install this instead stock dialer and you will have call recording:

How To Guide Workaround for 90HZ lag

As everyone here should know, there is a problem on the device where after a while using the screen at 90HZ, the interface starts to lag and it is necessary to restart the device. Here is a palliative solution, but for some it may be definitive:
1 - Make sure the screen is at 60Hz. Go to network settings and switch from 4G/LTE to 3G;
2 - Put your device in airplane mode;
3 - Change the frequency to 90Hz again and restart the device;
4 - Wait for startup and remove airplane mode;
After that, it is possible to use it without the problem mentioned above.
Tested on MIUI 12.0.11 and 12.5.1.0 EEA.
In some cases, after performing this procedure and returning to 4G, the device may not present the problem for a long time. However, it is likely to happen at some point, as it appears to be connected in some way to the mobile network. Hope it is helpful.
Alternative solution Edit:
Found by @wetito, working for some, but for me It didnt, try by your risk.

I don't believe it. But it could be some inconsistency in drivers or hardware. Phones from Realme like Realme 8 5G/Narzo 30 5G also have this problem.

in normal use now i don't see any rilevant lag. but i have not tested in gaming. only video streaming, social, ecc. you have already enabled the gpu render on developer option? also disable swap (ram extension) is a good thing to do. Facebook not lag also via web browser. with 90hz. if the system lag, facebook scroll is terrible. tmy render graph is normal. you can see on screenshot. software render and swapp are the first causes of lagging in most of systems. also for PC
edit: also choose a good theme is important. recentrly i tried a theme from store that cause a lot of system lags within 90 and 60hz. so my conclusion is that lags aren't necessary related to 90hz frequence

Do you have a VoLTE SIM? Because mine is still lagging when I swith to 90hz, I have MIUI v12.5.3, and I think VoLTE and display lag is related somehow.

My phone by nothing to do it's fixed! It's odd. It's great

Other than that it seems to be working as normal.

I have imported India version with FunTouch OS 12. Got the latest update too.
The phone seems to be working very well.
The only issue I have since I got the phone is when adding card to google pay contactless payament cannot be activated. I do not have loacation resrictions using gpay and with my other phones gpay contacltless payment can be activated successfully. My vivo is not rooted and runs factory rom.

Nice to here. Vivo is taking actions hard and fast, But still we should not get these bugs in Flagship modules.

Bringing out the scam companies like Samsung, Vivo are doing. Am using Vivo X70 pro plus. Recently I updated my software OTA push to 36.9.7 (from 36.8.) but took a camera sample before update. Immediately after update took another sample i matter of 15 min gap. There was hell lot of downgrade. Plus other bugs impacting day to day usage. Wanted your help to voice this out. Below are the identified issues beimg faced.
1. Camera quality is greatly downgraded
2. Background apps getting auto closed like Nova Launcher, SD Maid, Accu battery, etc. Thus accessibility service also not working linked to these apps as tgey are automatically getting off. This was not there before the update.
3. Amazon app is getting auto closed at payment selection page every time thus amazon app now not useful.
Attaching unaltered image sample before & after update.
3.3 mb is the one before update
3.5 mb one is post update (see tubelight & flower design on the matress, etc)
Can someone guide me on how to voice tjis to Vivo. This is malpractice as I suspect deliberate downgrade of camera & other bugs.

I dont see a downgrade or a difference at all here.

Look at the light, in post update image its bit spread, less t star
Also if you compare flower images on the left, you will clearly see that new images has distorted details clearly evident
