Did? you spill anything on your device or drop it. When you press a key does it light up?
1. reset your device. if that does not work pull the battery reinsert it and try again
2. try to access the boot loader or power on the device. if it powers on that means your end works.
3. You may need to hard reset your device but back up your files first.

I appreciate your kind consideration to my problem, Yes device dropped from hand from almost 4feet height but it was working perfect at that time but a day after its front buttons were not working properly.
I did factory reset many times and hard reset as well. but doesn't work.
touch screen & front buttons both doesn't work together, if front buttons works then touch doesn't at the same time. and mostly touch works & at the same time front buttons doesn't work.
Please help me, because i don't want any shopkeeper to handle my device.
Kind Regards

how do you fix it¿? i have the same problem.
I´m installed a lot of roms, and the problem persists.
excuse me for my english.

Re help with galaxy tab 2 power button !

help with samsung galaxy tablet 2 power button !
*Hi guys*I'm finally making the move and have bought a Samsung galaxy tablet 2 for my bmw e46 dash but have found a problem and wondered if any of you guys have a work around for it ?As you know the power button is on the edge of the tablet externally so once it's installed behind the dash you can't push it to either lock the screen or take it out of sleep mode and also it doesn't matter have a proximity to sensor built in etc*Any idea how I can press this power button while it's behind the dash either by the touchscreen using an app or another way that anybody can think of cause I'm stuck ??*So help ppl**

I've read some people use an app called TASKER to set it so that when they crank the car (giving the tablet power thru the charger) the screen comes on and stays on till its turned off. maybe check more into that?

use a custom rom with volume key waking up option.

If he won't have access to his power button after mounting the tablet in the dash, he probably won't have access to the volume buttons either.
here is a thread from another site where a guy put a nexus 7 into the dash of his vette http://ls1tech.com/forums/stereo-electronics/1584175-c6-android-tablet-stereo-dash-install.html

If your'e thinking about doing a hardware mod , Try AdamOutler (XDA TV) He does some pretty cool stuff and may offer some solid advice. Knows his stuff thats for sure.
XDA unboxing /tutorial Adam Outler style
Guess you could move the power button onto the dash itself if the device is getting built into it as a permanent fixture ? Not that id have a clue how to do that lol.

Not making any mod to the tab: You may mount a solenoid, http://www.solenoidcity.com/solenoid/solenoidcatalog.htm on the dash to actuate the switch. Will require some mechanical / electrical skill to accomplish the job..

fixed?
did you ever find a solution.. I have the same car and the same issue
Thanks!

Thing is you can easily get apps from store to
1.lock screen
2.turn off tab
3.toggle volume
But real problem comes with turning on tab...
Though you can turn on tab from sleep via some apps called smartawake and others(believe of there are lot of them on play)
By these apps you can turn on tab using proximity sensor(it will work),vibrations
But for instance when your tab gets off you have to press power button.
That can be done by pressing in physically or a hardware hack(you got to open up your tab and do stuff with your power buttons.like providing external switch to it etc)

Hey guys I am having a similar problem with my galaxy tab install in the car. I come out in the morning and the tablet is dead. I am currently charging it via usb but was planning on putting a power inverter in the glove box for faster charging (maybe?) What I would really like to do is to be able to extend the power button leads to an external button that I can mount in the dash. Anyone done this before or have any suggestions?

Someone recommended Tap Tap App (lock and unlock the screen with a double tap on the proximity sensor) around here. I've tried it and it works.

Yea that would work for turning the screen on and off, but im talking about if the tablet dies completely. It will be getting charge when I turn the car back on but I wouldn't be able to turn the tablet back on itself because I can't get to the power button.

Your Tab will boot into charge mode. Maybe you can change the init script logic: if boot into charge mode, wait a minute, and then reboot into normal mode.

There are some changes that can be made to the kernel to boot the os when powering the tablet. I had this behavior on my lgp500 as a bug on cm builds. To keep the display on you can check keep display on during charging.

I'll try. But now I am so tired, back from my real work duty. A short break after driving my car for about 3 hours, 1 hour from home 3.49AM here

Just to over simplify the first thing that came too my mind was a knob with an off set round plug on the other side...turn the knob you push the button..

[Q] proximity sensor issue!

Hv Micromax canvas magnus a117
how can I disable the proximity sensor ?
Comment:
Hey guys I broke my phone's touchscreen glass (and the proximity sensor stopped working after that)
now when someone calls me the screen become's UnTochAble , so I can not for example dial a number or Hang Up when I am in a call .
I undrestsand it is because the phone's proximity sensor that thinks the phone is close to my ear and it shouldn't allow any button to be pressed. I cannot use my phone even after the call is disconnected...screen dosent turn on and the proximity sensor dosent stop
how can I disable this feature so I can still use my phone ?

Suggestion..
Since I am on a different ROM I cannot tell you exactly the steps necessary.. But go to settings>accessibility.. There you should be able to find the solution.. Also there is an option power button ends call..
If your phone is rooted you may use GravityBox to change the way the proximity sensor works..:good:

Yes my phone is rooted..im using stock mmx os ..ive tried the power button method .but it dosent work.. Pls give me a way to disable the sensor... Please

to be honest, the idea is valid, and good, but its kinda pointless. why pointless? ill tell you.. what if the phone is powered down? and what if you are in recovery? cant use the hand wave for that, can you? see, pointless(mostly). ive had many phones where the power button has died, and each one i found ways to power on/off without using the button. yes, from a power off state, or from recovery.

yes you are right about if the phone is power down, but there are some cases where it will be helpful if the phone is powered on, so i will say its is still very useful.

I use Smart Screen Off, which has the option Of wave, speak, or flip to turn your screen on or off. I can't even find it in a search in the app store but I've been using it for a couple of years using the flip to turn off ONLY and it works great. I still use the button to turn on. I want a tap to turn on app but can find one that seems tonott drain the battery. Galaxy S3

Proximity sensor

Good morning, i have a Note 20 Ultra exynos version and when i test the proximity sensor i have no response. It's possible ??
Thanks

yes, it is implemented differently. it works fine with apps that support it

What do you mean by "test"?
When you're on a phone call it should turn off the screen if you cover the sensor.

No if i cover the entire note the screen is always on.

Using the mic not in speaker phone mode?
If so it sounds like it's not working... phone screen should go dark when it's against your face on a call.
Try clearing the system cache on the boot menu, this may fix it.
Try it in safe mode for the off chance a 3rd party is the cause.

When i try with a call it seems to work but after two or three attempts the screen remain on also if i close the cover..

Not sure but that sounds like software.
You said cover as in a wallet case?
There may be a setting for that but if so I have no clue.
Doesn't sound like a normal operation unless it's a Samsung case and it's suppose to do that.
Don't think there's even a visible specific system apk for it. You could try clearing the Android Systems cache maybe data too but that may cause more trouble with lost settings... and end up worse off for the trouble.
On the note 10+ a small faint blinking circle is visible about a quarter inch to the right of the front cam cut out when the proximity sensor is active. Not flashing, not active.
If that helps you any...
Note: if it's active during a call and I trip it 2-4 times with a second or two spacing, the screen will remain off until I turn it back on.
This is normal operation.

Ok thaks a lot for your explanation..

I'm having the same issue which started today. Every time I put the phone up to my ear to place/ receive calls the proximity sensor isn't working and I'm pressing all random buttons accidentally with my cheek. I've turned my phone on and off to try to get it to work and no dice. It was working fine before today so I'm not sure what happened. I didn't drop my phone or anything. A google search showed this has been a problem since the S10 when Samsung embedded the sensor under the screen and dropped to turn on/ off this feature under call settings.
Advice anyone?

Try in safe mode. If it works there it's most likely a 3rd party app.
Was -anything- updated or just installed?
Did you change any settings?
Try a "hard" reboot and clear System Cache in boot menu.
Clear Android Systems cache.

Is a hard reboot restoring everything to factory settings? If not can you provide me the steps I need to complete to get there and If I need to back up everything and how to go about doing that? I'm a novice who's learning everyday so I appreciate your patience

No! Not a hard reset!
Hard reboot simulates pulling the battery...

I think I got it to work again. Hard reboot I guess according to google is pressing the “Volume down” and Power / lock key for 10 to 20 seconds bypassing the options shown on the screen until the phone turns off by itself. I then pressed the volume up key and the power/ lock key until the android recovery menu came up on the screen. I then chose "wipe cache Partition" and rebooted the phone after that.
It seems to be working again and hope this helps anyone who starts encountering this problem like I did.

Clearing the System cache can fix a lot of Android voodoo gremlins. I clear mine regularly or if the Android is acting erratically.

Hello
I am the owner of a Note 20 Ultra starting today.
I previously had a Note 10 Plus, where the proximity sensor showed as a blinking white light near the front camera.
At Note 20 Ultra there is no sign of its presence, no blinking light. Is this normal? Can the real owners check and confirm?
I also checked with secret codes:
Using *#0*# and selecting Sensor opens a menu where I cant find any proximity sensor
Using *#77692# opens a window with proximity and light sensor; for proximity sensor I turn on and wave my hand over the front camera area, it vibrates and turns display green each time, but after several attempts (7-8) it stops working.
So, is this normal? It has a new algorithm or type of sensor?
Please check and confirm.
Thank you

Its possible that there is no sensor, I have not done any research on this but it is possible to use front camera as proximity sensor. It would mean that the function would activate when you are on call and not on loudspeaker, it should not be tough to implement.

It has a discreet proximity sensor...

I have seen this article but it is useful only to locate the proximity sensor. But regarding how it is actually working, there are no details.
I was expecting something similar with Note 10 Plus but there was no blinking led/pixel to be found when having a call.
And honestly, I am not very impressed with its functioning. When using phone on left ear especially it skips activating many times.
Also, during a call (normally not on speaker), when I cover the top of the phone with my hand, the screen does not go black instantly (I must keep it covered about 3-4 seconds) but if I puck up the phone to my ear it seems to activate, which makes me think it has an algorythm that includes other sensors like gyroscope. Or maybe my proximity sensor is faulty... but as I said, if I test it with proper code, it seems to be present and work.... Which makes me thing it is a software problem.
So, I come back to my previous details and kindly ask other Note 20 Ultra users to replicate similar behaviour.
Thank you

My note 20 Ultra sensor works fine if the speaker is off. Turn the speaker on and the proximity sensor is disabled.

Try using this code in dialer.
*#77692# and then turn proximity sensor on and put hand over top part if it lits up green then it's working as it should. But if it remains white and nothing happens then there is an issue with sensor.
