Xiaomi Mi 9T front camera no longer popping up - Redmi K20 / Xiaomi Mi 9T Questions & Answers

This is what I was afraid of when I bought this phone for my wife.
Her front camera is no longer popping up when it should.
She has tried restarting the device to no avail.
Is anybody aware of any bug or software issue that might be causing it to not pop up, or do you think it's simply a hardware failure?

Pop up camera just stop working or cell was dropped or something else that could affect pop up camera? If not, my suggestion it's claim warranty. I had this cell since 6 weeks ago and no issues with pop up camera but notice I'm not use pop up camera too much/often.

Start front camera in app and try little to press down camera....maybe this help...

TPT ICS Feedback

OK for all the lucky people who have suceeded in updating their tpts to ICS, would you mind sharing feedback. I'm currently on the CM9 port which is stable enough for my use and I don't want to upgrade to ICS and lose CWM unless it's worth it:
1. Do both front and back cameras work?
2. Does Sound work properly?
3. Is there still the "pen wonk" problem where the pen develops a mind of its own and just stops working?
4. Is the tpt any faster than before (i.e boot times, application launch, etc)
5. Any noticeable lag during usage?
6. On honeycomb, the tpt is unresponsive to touch immediately its woken up from sleep for like a second. Is that problem still on ICS?
Feel free to share any other issues encountered. Thanks
Hey,
1. Both Cams are working
2. Sound is still a bit quiet, but it works
3. after the update i hadn't any problems with the pen
4. In my opinion it is much faster then before and there hasn't been any crash since the update
5. I don't see a lag
6. This problem is still there, but not as much as before.
Thanks @folkommen, I'm sure this info will be much useful for me and others
Can anyone else confirm that the pen doesn't suddenly stop working during usage? Please make sure you're using the pen for a decent amount of time as this issue seems to occur randomly but usually 10-20 minutes of writing.
Did the ICS update fix the GPS (or make it better)?
Focus?

Some have reported it fixed but Lenovo is actively working on the issue now and has an idea onmthe hardware side what may be wrong.
AT 05/25/2012 is the WE Version released, with the same problem as UK: some G3 Providers are missing the connection for internet, Bad supply recharging, busybox problems disabled upgrade.
My Upgrade was succsessfully. No problems, not before and not after the update. G3 works fine. GPS fixed within 10 s 6 Satellits.

Snapchat camera issue?

Ok...something strange is happening when I use snapchat. I take a picture and than the app closes by itself and the camera refuses to work until I reboot...any other camera app will just gove a can nit connect to camera message until I reboot. Ill reboot and any camera app works (stock/instagram) but as soon as I try snapchat again...it auto closes when I take a picture and suddenly the camera wont connect again.
The strangest part is it was working fine earlier...ive been using snapchat since I got the phone with no issues...so not sure whats up...ive uninstalled and reinstalled...so not really sure what else to do...anyone have any suggestions? Anyone else experience this? Do you think maybe its hardware??? I dont think its hardware cause it works fine until I use snapchat...but idk cant figure this one out
Also, I have done notging new to my phone...no nee apps, no new mods, no new updates...nothing so there really is no reason for this behavior. Ill try odin later but im away from my oc at the moment and just wanted to get other peoples input
Edit: snapchat appears to be working again...still strange that that happened...makes me worried as I dont know if it was the hardware or app failing

Fine for me. No issues no lag
I've had the same issue a couple times. It's really weird. It only happens on the rear camera (the 13MP good camera) and only in certain scenarios. I tried to take a picture of my hammock, it locked up and I had to shut down. I took a picture of the ground, no problems. Hammock again, locked up. Flash on/off, doesn't matter. Weirdest thing.
I think it might be the camera software switching between white balances automatically (no proof to back this up, but since it matters where I point the camera, it has to have something to do with what the camera is seeing and doing in response to the scenery) and SnapChat might not play well with one of the white balances.
I just now took a picture of my driveway from inside my house, no problem. Took a picture of the hammock in the yard, freeze up. There's a lot of green in the hammock shot, I don't know if that has anything to do with it.
Have you guys factory reset. First thing I did when I turned it on
My girlfriend's s4 is doing the same thing she only gets it on the front camera but can make it do it at will she says it when the camera first turns on and is focusing and adjusting the color of you take a pic before it settles down it does what the op said.

i think your hammock is cursed o.o and i have no issues. it works fine on both front and back cameras in snapchat/any other camera app.
sorry to bump an old post but did anyone ever find a solution to this problem, its been happening to me on my gs4 from verizon. It will work then all of a sudden it does the same thing with the camera and just exits the app?
Same deal on my Galaxy s4 that is barely a month old. Everything was working perfectly fine until a couple of days ago when I try to send snaps using the rear camera.
Goes something like this:
- Take photo with rear camera, app crashes
- Screen freezes at the Snapchat 'loading' screen OR nonfunctional camera within the app (whereas everything else works such as receiving incoming snaps)
- Rebooting works from time to time, but the problem is reoccurring
- Tried clearing cache/reinstalling the app, no luck
It's starting to really get on my nerves.
I had the same problem. Snapchat force closes and camera starts to fail. I contacted the snapchat team and reported the problem. I got a reply saying that they are working on it. Maybe you guys should send them an email too and explain the problem you guys are having.
I have the exact same issue. I've not been able to find a work-around.
snapchat freezes on videos that are longer then like 2-3 seconds it seems... then i have to restart again to get the camera back...
Nothing is wrong with your phones. Snapchat is an extremely ****tily programmed app. What do you expect from a terrible iOS port?
I might suggest Wink! as an alternative, but it doesn't support video, but meh.
Yeah I have the same problem. It's fricken ridiculous. When will they fix this?

I think it may have to do with using the CM/non TW camera.. Whenever I used it I experienced this very problem. Since I've gone back to TW, I have not..

Camera problems

A friend of mine gave me a Nexus 4 with a camera problem. He said that, after ota upgrade to the last version of kitkat, camera stopped to work ("camera not connected" error). Both front and back camera don't work, and led flash too. I've tried every version of android stock, cyanogenmod 10 and 11, and franco kernel too. I've open the phone and unmounted every piece: nothing looks wrong. Maybe logical board? Or a defective back camera? But led flash and front camera don't work too. Maybe a software problem? Thank you
Try reverting back to 4.2.2; see if that fixes it. If not you might have to open it to make sure the wires for the camera is connected.

Try to flash the Google stock ROM with a toolkit then it should work
Gesendet von meinem Nexus 4 mit Tapatalk
But, as I already wrote, i've tried to flash every N4 android version (with unified toolkit, of course), and I've unmounted every piece and everything looks ok. I don't think the back camera is broken, as front camera and led flash don't work too.
Do u think that if back camera doesn't work, the front camera and flash led are off? I tried now without back camera, now without front, and i've the same error.
can you share your topical setup rom+kernel...?
---------- Post added at 05:14 PM ---------- Previous post was at 05:07 PM ----------
try also to delete your app data off the camera (gallery) in app settings or try another camera app in the playstore and check it again. if nothing helps i think something inside your device is broken

VR Apps with white dot and rapid clicking

Hello everyone I have the HTC One M8 running CM13 and I have this problem where VR apps start rapidly clicking with this white dot in the middle of the screen as soon as they're started up. The phone then becomes unresponsive as it is registering clicks from it, making the phone freeze up. The only way I can get out of this is by locking the phone and rebooting the phone from the lock screen. I thought it was the magnetometer in the phone doing this so I installed an app to read it and searched up the normal ratings for what the sensor should be at and everything looks fine. I have tried reinstalling Android with a different version and still the issue persists. After a while the phone starts heating up from this and on some of the VR apps I have tried that use the same cardboard system the phone will rapidly vibrate as well. I have spent hours trying to figure out what may be causing this and still, no luck. The phone is not in a case, no magnets are any where near it. NFC is turned off, all apps are updated. If anyone knows a solution to this issue that would be great, thanks!
*Bump* I still have this issue, can someone please help me with this?
It now seems to be happening in Pokemon Go... *Sighs*

I have the exact same issue, the only time when the white dot wasn't showing was when my gyroscope was malfunctioning or just simply "off". I have no clue how to switch it off though.

had the exact same issue. same in pokemon go which ist a vr app. on several cm13 roms on my old m8.
only way i could fix it was to install a GPE rom. might be a cm13 bug for the m8 which never got fixed. so i guess anything not cm (aosp, gpe, stock) will work.
i dont own the m8 anymore but my old one and the one of a friend had ur issue on cm13. on gpe rom everything worked.

This problem was fixed a long time ago. The problem was the uncalibrated gyroscope, which they took out a few days after this thread was made. Just update your phone and it should work
Same exact issue
I have an Lgg3, same process I removed the magnet thinking that was the issue, I updated all apps, removed app and re-downloaded them, have an unlocked phone running total wireless so I used a Verizon sim and updated the phone to the newest version, recalibrated the phone, nothing I mean nothing I can find will work for this issue that I can find. Only does it with 360 apps not on 180.

Audio missing randomly/Can't play Music or Videos (Software or Hardware issue?)

(I know there's a thread about the audio cutting out every 2 seconds, but mine is a bit different.)
Audio would play just fine for a day at most, then randomly all the audio would stop working.
More specifically, I get a music playback error, videos on facebook and youtube can not be played, and audio for games are absent.
I'd wake up and my phone alarm is missing.
The audio doesn't cut out the first 2 seconds of a video, at least not that I'm aware of. Audio everywhere just stops working.
Although, I found that clearing the cache and memory would sometimes fix it temporarily, as well as closing all apps.
Ultimately, I would restart the device (Since videos still won't load) and it would fix itself temporarily for another few hours.
I've done a factory reset, and the problem still persists.
Should I be worried if this is a hardware issue? I feel like this might just be a software issue alone, so I'm unsure whether to wait for a new software update or turn it in for a different phone.
I am also facing the same sound problem in Germany on O2. The problem starts randomly during a call and after that no sound in the whole mobile works. Earpiece, speaker, headphone and microphone stops working.
I have tried factory reset but it didn't resolve the problem. I have even tried Safe Mode, but the problem appears in that too.
It seems like phone app takes control of all the audio and then fails to release the control.
The only solution is to restart the phone.

It happened to me on S8 and then I replaced with S8+ it is even more worse than that.
I found the issue. For me, it was the Facebook application running in the background. It's taking too much memory and causing the phone's audio to break for some reason.
Deleted it and I haven't had an issue with the audio ever since.

It is not a facebook issue in my case. As I have tried in safe mode and this problem appears in safe mode too. In safe mode, no application can run except systems apps.

It came back after 3 days, ya isn't facebook. This is too annoying to deal with.
It is a hardware issue, I can tap hard on the back of the phone in the middle and sound returns, try it next time.

I tried that, but it works better when I just clear the Ram/Cache. Which makes me believe this is a separate issue, more software than hardware.

It still happens after a cache clear, and clearly if you bang on the phone and a speaker stops or starts playing, thats a hardware issue. There is no software that would do this.
I believe it's both a software and hardware issue depending on the phone you got.
I really wish Samsung would do more to solve this issue.
I just found the problem to my issue.
It was a software issue, Facebook Chat Heads was interrupting the audio and video functionality.
I disabled it, a week has passed and the problem has disappeared.
