[Q] Camera Unable to Focus

Hi,
I have a H1 and today morning i thought of taking some pictures in my garden. Everything went on fine and then all of a sudden my phone's camera was unable to focus on anything. it just stays blurry. and when in touch to focus it just keeps changing the metering. if i turn the app off for 5 min and turn the camera on again it focuses for a few seconds and then again loses focus.
Could this be a hardware issue or software issue? im running ARHD 7.3 with a stock kernel.

I had tried that among other things like changing kernel and upgrading from arhd 7.2 to 7.3..
.
But I noticed something, my battery was low so I was running at 1ghz and now it's at 50% and the problem has gone... Could be a mix of diff software issues.. Fixed for now though... Whew!!!

I am having exactly this issue..
After a few seconds camera can no longer focus -

Could be due to low power or might also be because of dirt/dust/spec in your camera lens

i fixed the issue buy just putting my phone on charge! it was definitely cause of the low battery. ive programmed setcpu to underclock it to 1ghz when it reached under 25% battery, so that was causing the issue..since then ive not seen the issue crop up again. i highly doubt dust can get in so there shouldnt be any need to panic about it.:good:

hmmmmm....wow i thought it was a custom rom issue..maybe rooting the phone and the installing a cpu governer like daemon or setcpu might help..you try setting minimum frequency to 1.2 and see if that helps..
coz i got myself an O2 version from uk and installed a custom rom on it.. and well one morning it started acting whacky..but putting it on charge helped..it could be possible..i sifted through the other posts and i believe we are the only 2 people who have faced this problem..but had it been a hardware issue it would not have been fixed so easily so im pretty sure its a software bug..

Could be a problem with the camera sensor over heating

Wow is that even possible? I did not know that.. The problem Did come up after I tried some panoramic shots and a few regular pics out in the sun..

T-mobile have offered to replace my phone
And HTC UK have offered to take it for repair..
Not sure which option gives me the quickest turn around.
It's annoying as it works fine from time to time.

That's sad.. Coz I know how it feels to not have your phone with you.. I was lucky then I guess that it got fixed for me automatically.. But dad's theory could be correct about the sensor heating up.. Keeping in mind that it's more sensitive to light in the first place
Sent from my HTC One using xda app-developers app

and the problem is back again i was out with my friends last night and we were testing low light capabilities and the moment i switched to hdr video the camera gave up again... now its not even able to focus after being put on charge.. i tappe the phone a couple of times and it focussed but again failed..you think its a hardware issue
? or a power management issue by the kernel??(tried stock and bulletproof kernels)

Definitely sounds like the sensor overheating. On a lot of dSLR cameras with video and live view, they switch off after a short time to avoid the sensor failing

But I left the phone along overnight and it still had trouble holding focus for too long.. 5 or 6 seconds max... Could there be a possible software issue too coz apart from me only one other person is facing the same issue..
Sent from my HTC One using xda-developers app

That is why it sounds like hardware fault. If it was software, then more people wold be getting the problem.
Once it has cooled down for about 5-10 mins then it will work again, briefly.
Send back for a replacement, is my recommendation

i cant...i had it imported so its almost impossible to get it replaced..ill have to figure something else out...

Anyone else facing the same issue? it keeps cropping up again and again..

[Q] Random touches, can someone help with a fix ?

Hello there
Did any of you experienced this problem :
http://youtu.be/hitxapYdGl0
If I lock and unlock the screen, it solves it temporarly, untill the next time it occures.
Tried every fix found on xda ( dissabled x-reality, done the calibration thing, etc )
Flashed anoter .ftf firmware ...
If anyone has a sugestion, or a possible fix, i would try it happily.
If not, I will put gasoline on it, and burn this "*****" down ...

Seems like a hardware related issue to me

I have same issues sometimes, but didn't try to resolve problem.
I lock screen and unlock, it fix for some time.

Well, honestly this is not a 100$ phone. So things like this should never happened ...

It's a globally problem

Are you having this problem ?
I have a friend with a white Z1 and he isn't suffering from this.

Someone should contact sony centar about this problem, unfortunatly i cant because i leave in country that companys dosent love so much.

I ve removed the anti shatter film from my z1, The screen feels more responsive now ... I ll wait and see if the problem still persists ...

Ok, give me report on this one.

Ok ...
Things i've noticed so far :
- touchscreen is more responsive without the antishatter film
- if the phone is used only for basic things and does not heat up, the touchscreen works flawlessly
- if the phone is used intensively and heats up, things start to look messy ( for example if i run quadrant 4 times in a row, there is a very very big probability for the "problem" to occure.
- if the problem occures, regardless of the temperature of the phone, if you lock it and unlock it, the problem disappears, untill the next time it appears.

OK this is definitely a hardware issue for this device (globally, it has to be). The only I fixed it is my cleaning the grease/oil/sweat etc from the screen with a piece of cloth or directly washing it with water. I do this once in 3 days, I no longer experience this issue when the screen is clean.

Made another video
https://www.youtube.com/watch?v=N42NX8hP8nM
Ran a stability test which heated the phone to ~40 degrees. As you can see in this video, the problem starts to appear, and disappears as the phone cools down. This happens every time I run the test and the phone gets hot.
Well f*** you Sony !!!

I have exactly the same problem! Only lock unlock fixes it for some time. Very annoying!

It is hardware problem. I had the same problem and replaced it with brand new phone
But I have a new problems on new mobile
Notification bar comes down itself very often (see video below)
Sometimes screen stops working and I have to restart phone
Restarting fixes the problem for a few hours
Can you tell me is this software bug or hardware problem? I can not contact support at this time

i had experienced this problem but it was no hardware problem
+ try to remove any screen guard if applied to your screen

[Q] Htc one m7 screen problem

Part of my m7 touch screen isnt working .. its kinda crazy cuz the phone never got dropped .. i saw that many people had that problem its between this two parts of screen that doesnt work theres a line that working..sometimes the touch isnt working at all !!
(when people call me sometimes).
its really disappointing cuz i like htc very much !
another problem that im having and saw that many people has it too : screen brightness always go maximum ! auto off for sure but still the brightness making problem tryed to reset the phone didnt help( not hard reset) it sucks to have a bunch of problems in a new phone ..
please please help me !
post.img.org/image/6naksobvx/
delete the dot in postimage ! sorry but this photo will help you understand and i have to share it !

Areas of the screen not registering touch input in most cases is a hardware issue with the digitizer. Loose digitizer connector may cause similar issues, but the only way to check is to open the phone. Opening is not easy and there is a high risk to damage the body. If you decide to go this way, my suggestion is to get new front and back panels + screen kit and to transplant the rest into the new housing. It's also a good time to replace a worn battery or a faulty camera module.

some times the screen back to full funcanlity
and please help about the other problem with the brightness .. its look like one of the sensors is broken in the phone .. maybe its the problem ?

When Auto Brightness is set to Off, the phone is not using the light sensor.
You'll have better chance to get help if you provide some basic information about your phone:
- What OS version? (KK, LP, stock, custom)
- Was the phone factory reset after the last OS update? (highly recommended)
- Do you use any applications that control screen brightness? (like some picture viewers, barcode display apps, etc.)
You may fix the brightness issue (most likely software related), but non working digitizer on parts of the screen is hardware related and no app will fix this.

lollipop not root and other .. i deleted everything , did a soft reset not the hard type . no but i download lux to see if its help and it doesnt help either

The only thing left to try on a software side is factory reset the device. Many users report it clears various OTA Lollipop update bugs. The process takes about 10-15min, the OS will go through Android system update process again and the device will be reset to factory default state (don't forget to backup all your data). During the initial setup process don't restore your online account backup, make clean setup. Test the screen and digitizer before installing any 3rd party apps. Make sure your screen protector (if you have one) is not bugging the digitizer. If you have the same issues, then it's definitely hardware related (screen/digitizer assembly or connecting ribbon cables).

Samsung Note 9 - Display Discoloration & Overheating

Who else are facing the same problem ?
1)Initially, when I unlock phone by pressing power button the display was changed to dim colour(mostly yellowish) and with horizontal lines displayed when the brightness is below 50%. After tried with multiple times pressing on power button the display came back to normal.
2) Next stage, it's not solved with power button. I have to keep my phone aside for some time to get back to normal display. It's been 15 to 20 min then.
3) Now, I would get normal display only in morning. Else, I need to keep my phone idle without touching for at least 4 to 5 hours. I've also changed screen power off time from 30 Sec to 10 Minutes. So that my screen wont turn off and I can keep the normal display. If I forgot to use or kept aside more than 10 min then my screen would go off and display would gone again and irritation starts with that discoloration problem..
4) If display changes to yellowish to reduce the horizontal lines problem I need to increase the brightness to 80 or 85% but this causing my phone with another problem "heating issue"
Samsung haven't responded on this issue yet, how could we bring up the issue and get the proper resolution from Samsung.

This happened after last March update installation?
What note 9 do you have?

Probably not a hardware fault if it happened after recent software update.
A number of note9 affected although samsung seems to disagree at the moment.

Hello,
I also have a problem with the display after waking up with the POWER button. There are tinted colors distorted and some stripes like dim lines and slow refreshing. Everything started after updating to Android 10. In fact, when the display lights up incorrectly, it starts to heat up from the bottom. Putting the smartphone aside for a moment or cooling down causes the display to work correctly.
Workaround? I turned on Active Display and first knock to activate it, then the display lights up correctly and then I unlock the screen and use normally. It is known that battery consumption increases. Of course mine is Exynos.

hi guys,, i remember a similar experience sometime back.. try this. if u have turn on the proximity sensor i mean the advance feature where the phone screen doesn't turn on while in pocket , switch it off and restart the phone and see if the problem still exist.

i am having same issue
is anybody on xda come to rescue our issue?? friends need urgent help out ., if the solution is to reinstall the firmware kindly tell how to ?? while phone is just giving odd lines and not responding to touch even ??

whats the firmware version u are having now and phone model?

Try wiping the cache partition in Recovery Mode. If that doesn't work then back up your device and manually reinstall the OS back onto your device.

Im having the exact problem. I flash LineageOS and it worked by max brightness then back to auto. I installed brightness widget to max brightness and back to auto everytime I turn on screen.
This issue is popular after March update. I tried everythings you mentioned above, reset, flash new firmware, even April update, wipe cached, flash cooked rom, heat screen, turn off features, disable gpu overlay, etc... Samsung Vietnam guaranteed can fix with new screen but I'm out of warranty.

I dont have any issues us unlocked snapdragon xaa model on latest android 10 version.

Can we confirmed that a screen replacement fixes the display problem or is it still a software issue

No one knows what is the exact cause here, its noticed in many devices right after this March update but few are noticed months before. But, now the problem came to many users at same time. So its been brought up by many tech blogs, websites.

I'm having the exynos version too but with ITV (Italy) firmware ...never had this problem and now I'm on April's version after March's version.
This looks a little bit like what happened to the S5 years ago when after 1 and a half/ 2 and a half year's the screan began flickering, having green spots or lines, randomly didn't go on with low luminance settings since it completely died....a lot of people said on forum's that it was the screen and a replacement solves, but when it happened to me years ago the Samsung assistance center told me that it was another component (never told me what it was) causing the issue and once they changed it , they solved the problem.
So, after my experience with the S5, don't know what to think now for what is happening to some guys even if I think that this issue might depend with something happening after marchs update because for the too many people having it after the update, coincidences are not credible.

Yes, many people were facing this problem and how many times we have contacted the Samsung they are behaving like they just hearing the issue for the first time. Just created and posted the link in Members app and 67 members joined so far. Everyone having the display problem out of nowhere. All of them on out of warranty except one or two. Still members app floating with the display problem messages.
Display issue got noticed in S20 too but they immediately released the security patch and solved it. Don't know why they were silent on Note 9.

I've changed screen and after sometimes phone goes crazy

Hi mates, I need you help and suggestons,
unfortunately my phone felt down and I needed to change screen, the service which installed it asked me to choose one of the available (chinese) screens I I select the most expensive one. In the beginning all was ok, but time by time (about 1,5months) the usage gests worst, when the screen start to be a bit dirty it start recognize touches anywhere (moslty in the up side of screen), itself does commands, it's not possible to do nothing. WHen this happens I need to keep press the power button for 10 seconds tille ht ephone reboots, after reboot all become regular.
My considerations:
1) it doesn't seams a defective screen or a bad assembly, because after reboot all is good, if there were such problems a simple reboot can't fix them.
2) it looks like an incompatibility between OS and the touchscreen firmware, and probably it's something Xiaomi does with intention to create problems for cloned spare parts. Maybe the OS is "instructing" the touch screen controller how much sensibility to use, how much it can be dirty, etc.etc? the protocol of the latest OS isn't at all compatible with the cloned device and it result on crash of functioning. A reboot solves the problem.
If that is right, will a ROM update to another OS (not IMOU, as I have now) can fix the problem? Or there is any app that can perform a touch screen reset? Or any other trick to solve my problem? Than you for answers

Hi mates I need help, with cold weather coming it got crazy as soon it feels cold. WHat can I do to solve problem?
Updating ROM to a non official can solve it? The display isn't broken! A reboot fixes always the problem..

It is not original screen from xiaomi vendors, just a oem part with lower quality (chinese sell it alot on aliexpress with many type amoled, oled and LCD panel too).
Ghost touch easy happen on oem screen no matter how expensive it is.

Thank you for your kind answer, this is a really big issue.. it's very annoying using the phone like that, I've noticed it suddelny starts when the phone is exposed to cold temperature: lowering the screen temperature quite suddenly means it goes crazy, when it's crazy the only way to fix the proble is reboot the phone, with reboot it calibrates again and works ok, till next event. MY question are:
1) Can I forse myself a calibration?
2) Does other ROMs, not MUI, manage and fix this problem? (using another touch driver may solve the problem, chances are MUI introduced updates and become more selective to work with only original displays, to disancurage the OEM parts, so using another ROM wuth an older driver may solve the problem)
3) If I buy and add a protective glass on display, does it behave better?
Your experience is essential for me, thank you for posting!

imo
1. you can not
2. Roml sorfware can not
3. Protective glass make lower touch experience.
- Not all oem part come with defect, some working fine, it is just random.
- To repair you need replace new one, or buy original screen for sure.

Thanks for answer, I do believe that the problem can be managed by drivers, "resettig" the touch chip wil correct the problem. Probably the defect is on the firmware of the touch panel, it gots errors from touch.. ok, but it doesn't understand it's just revealing mre and more ghost touches. These FW have the task to filter out the ghost,, maybe they don't do it well.
A second chance is the comuinication between this chip and the MUI OS, the connection goes broken by some mistakes, "unalligned" and MUI got any touch position from nothing.
I don't believe the screen is defective, because after reboot it works perfectly, thil the next strong environment conditions change..
What is Roml software?
