I have Speed Rom 5.1 on my Amaze. When I am finished with a call, the screen stays black. I try to hit the power button, but nothing happens. I have to remove my battery in order to reboot. Can someone shed some light on why this happening? I am thinking that it may have something to do with my CPU Tuner settings, but I am not sure.

Probably that or a bad flash, just reflash, see if it solves the issue.
Most likely it's something simple, like an issue with your proximity sensor. I know there was an app that could calibrate that but I forgot what the app was.
Stock Rom - Black screen while phoning
There is a similar problem on my wife's phone with a stock rom (not rooted Amaze from T-Mobile). When making or accepting a call, the screen will instantly go off even without leaning the phone against anything and won't turn on unless the power button is pressed. Sometimes the screen would turn on by itself after a while after the other phone was hanged.
I've downloaded AndroSensor app: the proximity value does't change even when touching the area near the earpiece. It keeps showing ( 0.5mA ) 3.5 in.
I've found a thread which is there since april 2012 and describes quite a similar problem.
okay.. i just the original post date for this thread.. please don't bring back threads that are 6 month's old which issues might have been solved already since no ones been posting in it for 6 months...
(anyways) this is what i was gonna say
on my current s3 when my phone is placed to my ear it cuts off the display.. and if you pass your hand anywhere near the sensor's to the top near the camera it cuts off the display.. maybe there's a feature like that enabled on the stock rom also.. or you could possible check with the system settings to see "screen" on/off settings in display or power saving mode.. or something...
Thanks for the answer. I didn't notice that the thread was that old. I think I will keep up a newer one. But the current issue isn't likely to have been solved.
The problem doesn't seem to be triggered by wrong sensor measures (because the screen will go off even after disabling the sensor) nor does it depend on the rom version (same thing on the CM10).
Resolved:
It will sound stupid but I have found a simple solution:
I have just wiped the screen in the upper left corner where the proximity sensor is located and it started behaving normally. Though I don't use any protection tape on the screen it seem to have become less sensitive because of mud or sweat.
I have the VZW gs3, running the stock rom with the motion lift to ear to call enabled. I've noticed that during a call, when you go to input numbers, such as if you are on automated call center, if you try and press the 1 key the screen goes black as soon as your finger gets too close to it. Then comes back when you are a little further away. Not sure about 2 and 3, but the lower keys did not have the same problem.
I thought maybe the phone is attempting to shut the screen off, thinking I'm holding the phone to my face maybe? Either way really annoying problem, has anyone else noticed the same thing? Is there a workaround or fix?

It's because when you're moving your finger to the 1 your hand gets in front of the proximity sensor, which turns off the screen. Just be aware of where the rest of your hand is and it won't happen anymore.
Yes, it's the proximity sensor so watch your other fingers and you go to press a key. I must say this is one of the most annoying things of the SIII I have found so far.
Alright, thanks, is the proximity sensor the two small dots next to the samsung logo?
One of them, yes.

Does that mean I can just bring my finger up to the sensor to make a call when texting? so that I don't have to press my face into the phone?
This phone has never been modified, no custom ROMS, never rooted, using the latest OS from AT&T ...
And today, for whatever reason, when making originating a phone call, and once I've hit "dial" ... the phone screen goes completely black except for the status bar at the top (the one you can swipe down). I'm saying that whereas usually, after hitting "dial" and as the phone dials, you can actually see a screen full of information (hang up botton, number/name of who your dialing, etc.) ... in this case and now, there is just a black screen.
Though there is a black screen (other than the status bar at top), I can still hear the phone ring and even have a conversation should somebody answer. But when the call is over (the person on the other end has to end the connection because I have no screen interface to do such), the screen remains blank (other than the status bar at top) and none of the bottom, permanent keys are operative either ("home" / "back" / settings / etc.). To get back to the home screen, I have to pop the battery and re insert it and re start the phone. But even then, it's acting weird: when booting, at the "Reimagine Possilbe" screen (I think that's what it says) it hangs there for about 45 seconds (usually only about 5 when functioning correctly) and will eventually end up at the home screen.
But if I originate a call, the cycle repeats.
I've completely reset the phone to factory defaults at least three times, formatted the USB storage and the whole nine yards but it remains glitched as described above.
...
So... has anyone seen/heard of this?
I'm thinking of just warrantying the phone as it's only about 5 months and I figure AT&T should have no issue as it's such a replicable problem and it certainly doesn't seem to be software related as it's completely stock and multiple factory resets have not worked but wanted to put a line out here first to see if anyone else has experienced this.
Thanks in advance for any information.
Best,
Joel.
I think the network is fugazi right now, as I had issues with the phone, and read about another user having same troubles. I'd give it a little time.

I sure hope so. Even though I've reset the phone (which sucks) ... I'd prefer that over having to go to the store and all...
Odd that a network problem could cause such, though ....
Thanks for the word ...

Just a llittle update ...
I changed the "Proximity Sensor" to OFF and now the normal iin-call screen appears but it never goes away, which can be problematic.
In general, I've always had the proximity sensor set to ON as this allows the in-call screen to blank after a few seconds (complete blank with no status bar at top) and then reappear when I remove the phone from my ear.
But when I re enable the proximity sensor, now ... the screen blanks immediately (excepting the status bar at the top) and never comes back ... even after my call recipient ends the call ...
I'm just gonna warranty at at the local service center; at this point (two days now with all my friends AT&T phones working fine) I'm pretty sure something is glitched with the internal sensor that manages the proximity settings ...
Thank God for warranty.
Hello,
Unfortunatel my device seems to have some kind of malfunction.
The Issue is that the devices suddenly locks andd just shows the clock.
I can`t unlock it. After a while it might show the normal screen and I can unlock it.
Then the clock comes back and I can`t do anything.
I reinstalled with wipe all everthing however after a while it will come back.

Any help is appreciated
Check for smart cover option in smart assistance
Turn it off. The pic you posted comes when you use flip cover (when closed )
Have u applied any sceen protector covering upper right (nr front cam) side of screen it may cause this
There a proximity sensor and one other idnt know name but it should be uncovered when using phone.
Or the sensor is misbehaving.

That may be smart cover problem
Every time I make a call, the screen dims and then blacks out in a matter of seconds. It's in an Otterbox Defender. I have tried every setting I could find and have it set to turn off display after 10 minutes but something is overriding that for this phone app.
I'm new to LG and the V30 but on my last device it detected proximity to the screen during calls so your cheek doesn't mistakenly hang up or something. I believe it uses the front side camera to detect your head there. Could that be what os going on?

Mine does the same and I dont think it's to do with proximity sensor. When i make a call on speakerphone or Bluetooth with nothing near the phone, it still dims and blacks out
I agree it's likely not the proximity sensor in this case as I always have it on a desk and use it via bluetooth but thank you for that suggestion. But, in many cases, I need to enter in several series of #'s for conference lines and changing options but the screen blanks out way too fast. When I double tap it to open the screen, I sometimes accidentally hit a # and have to start over again...

Do you mean it turns pure black, or just dims? Mine dims if I'm on a call utilizing the speaker. Just touch the screen to brighten it up, then type your conference numbers.

I have the exact same problem with my V30. I use Bluetooth, either on a headset or in my car. After a few seconds, the screen dims, and then a few seconds later, it blacks out completely. When it dims, I can tap on it to wake it up, but the screen still responds to the tap, so if I happen to tap where the hangup button is (easy to do in a moving car), I end up hanging up on myself. Or, if I'm navigating through an automated attendant, when I tap the screen to wake it up, it invariably hits a button for a choice I didn't want, and I have to back out or start over. Very frustrating! If the screen goes completely black, then I just hit the power button to turn it back on, but once again, it'll dim out in a few seconds. I would LOVE to have a fix for this! I like this phone better than the past Samsung phones I've had, but the Samsungs don't do this.
I want to add my frustration to this issue as well. I also have a V30 and this happens all the time. My mom has a G6 and says the same as well. It is simply unacceptable. If this is an LG-specific issue and it isn't fixed (or at least given an option to change the screen time-out) then this is a deal-breaker for another LG in the future. (same goes for the glass back as well, but that's another issue...)
Eagerly awaiting a fix or workaround....

I have the same problem on my V30+ since the oreo update. Before it was OK.
During call screen blacks out and then when I take my ear off screen it does not light up again.
I need to press the power button to have the screen displayed again during call. I wonder it this was not done on purpose in order to preserve battery
Nowever It's frustrating because I was not used to this.
Any ideas?
Thanks Anndy
Same frustration for me. I make regular use of speakerphone and it is very irritating.

No fixes yet that I'm aware of. The "solution" I use is to tap or double-tap on the very top of the screen where there are no buttons that will affect the call. But this is by no means an acceptable solution.

I, too, want to add my frustration with this problem. In my case, the screen goes black immediately after touching the phone icon to connect a call. I talked to the T-Mobile people who said they never heard of this before. This has been an issue since 2012, so that was useless. This started happening with the last update. Hopefully if more people complain, a fix will happen.
Same here...

I hope we can get a fix or an option to this soon. It really messes up calls when options are needed during the call.
I've had the exact same problem with my G6 ever since I purchased it (February 2018). It's really annoying and a problem when you are calling an automated voice system and it dims before you can make your selection and double tapping to wake can cause you to hit a wrong number selection (which happened the other day when I was refilling a prescription). Please fix this!
Happens on the V20 also with the latest update from Verizon. The only way around it is to tap in an area you think won't affect the call every few seconds. The number bar on the top seems to work. defintely need a fix for this. Really annoying

Me too! The solution? NONE, NONE, and NONE.
I called T-Mobile today about this very problem after my frustration hit the roof. I complained it's impossible to hold business conference calls on my phone because the dialpad screen dims in exactly 5 seconds. I need it fully lit so I can mute/unmute at-will for clear-sounding and respectful meetings. Yet, as every smartphone user knows, computer screens are no match against sunlight. I inevitably fumble my way around the dialpad on a bright day.
I did every configuration possible to mitigate the problem: Screen Timeout (none), Auto Brightness (off), Brightness (100%), Battery Saver (off). Nothing stopped the dialpad from dimming like usual. However, to my own surprise, all other apps respected my settings during a call. So is the LG phone/dialpad app itself ignoring my system settings? Yes. Yes it is. My theory was soon confirmed....
T-Mobile offered to do a 3-way call with an LG representative. The conclusion? I was told flat out it's a "feature of all LG phones", it's the "default", and there is "no way to change it". SERIOUSLY, LG?!?!? Shame on you, LG!!!! I didn't say that to the LG rep, but, I did tell her I will be "forced stay away from future LG phones" if there really was no solution for this and every other phone LG makes. She offered her scripted apology to me several times but, alas, there was nothing she could do.
PS: This is so, so, so disappointing. They could have kept their default but provided a system option to enable the app's FLAG_KEEP_SCREEN_ON. They could have taken my customer compliant seriously. So, for anyone reading this, if you want to do any active use of the dialpad during a call, stay away from LG phones.

Root, use Google dialer? Does it dim also? I have it installed, I'll check tomorrow morning.
Google dialer "Phone" app doesn't help...nope!
I gave a workaround in an identical thread somewhere else in this forum. Use Waze navigation app during phone calls. The screen won't dim. Drag the phone call thingy over to the Waze screen.
Found it:
ChazzMatt said:
When I have Waze navigation on, my screen doesn't dim. When I make a phone call, I go back to Waze map screen. I can drag the phone call thingy wherever I want. If I need to mute, unmute I just click that to go back to call dialer interface for a few seconds. Then I go back to Waze screen to keep display on.
Yes, it's a wonky workaround, but it works. When I use this while driving, I make sure my phone is plugged in for charging -- because the display will stay on for the entire duration of the phone call.

My LG G8X does the same thing, goes dim after a few seconds, then blacks out completely. In the day & age of "press 1 for this, press 2 for that" it really should allow for more time before the phone becomes disfunctionable...
New auto update on LG phone times out too fast
My LG phone auto updated to a 3 sec. screen blackout and can't be changed in any settings menu. The solution is to install the "Keep Screen On Free" app which completely solved the problem and lets you change the time out settings too.
