[Q] Volume down without pressing the button

I have a problem with my Topaz and have a suspicion it is a HW problem.
Several weeks ago I watched Futurama on my Topaz using TCPMP player (as many times before) and suddenly the volume adjustment screen appeared and the volume decreased to zero (but the corresponding button was not pressed). Since then this problem appeared every time I tried to watch a movie. Sometimes it helped to stop the movie and to switch off the display but sometimes I had to put off the battery.
I tried the HW reset but the problem appeared immediately after the reboot (when I imported my PIM data and the system was sorting the SMS messages).
Originally I thought the problem is connected with the high processor load but then I tried several tests and figured out that the problem is probably purely random and appeared here and there when the display is switched on (when I use Nitrogen player and let the display on, the problem appears, when I use the button on the screen to switch it off, it does not appear). Recently I tried to let my mobile with the display on (and no program running) and after approx. 30 min the problem appeared again.
What do you think? I have a suspicion it is a HW problem (a problem with the button sensor) and I will have to reclaim.

Did you do a hard reset by holding both volume keys and soft resetting with the stylus?

Yes, I did do a hard reset several times and the problem occured again and again. Yesterday evening I loaded the newest ROM and now I am testing it. Video is playing now and I am impatiently and nervously waiting...

I did some preliminary testing today and the system seems to be much more stable than with the previous version of ROM, which is highly surprising as I was totally convinced it was a hardware problem. However, it was a little bit colder today in comparison with the previous days and the overheating of the device (and the button sensor) is still in suspicion. I will continue in testing the stability of the system tomorrow.

And there it is again.. :-(
Although the frequency of the occurence is not so high. But still it is pretty annoying, the next week I will send the phone for the warranty service.
I think the problem is somehow connected with the overheating of the device, because I guess it should be no problem for the device to play a movie for one hour or two, even in 30°C heat.

Problem solved - the warranty service sent me a message that they found the same problem during the test and they changed the motherboard. I hope my device will be OK now.

[Q] Four buttons stopped working: Call/End call/Start/OK. What's the cause / how fix?

Hi, the 4 buttons - Call, End call, Start, and OK - have stopped working on my win mo device (kaiser aka tytn2, wm6.1). Keyboard backlight doesn't turn on when I press them. All other keys (including IE, messaging, both soft keys, and all the other keys on the device) are working though, and backlight is turning on with them. Maybe it's related to the fact that a few days ago after disconnecting this device from charging over usb it almost stopped responding so I had to reboot it (device was probably low on memory too just before reboting because of many programs running). Some time after rebooting I noticed exactly these 4 keys not working. Powering it off and on doesn't solve it, I have tried it several times. Trying to assign another action to OK or Start button didn't help too. Looks to me like soft problem still..
How can I find the cause of the problem and fix it thru some setts, user config, user cfg files, registry, etc?
Please help!
Edit: Also, is there a way I could test if Call, End call, Start or OK button is working at the lowest software levels that are possible (like in bootloader screen, etc.)?

OK

Is the phone irreversibly broken?

Hi.
I've own P970 Swift/Optimus Black since 4 and a half year, now with Android 4.0.4.
Lately strange things happen with it.
1. Softkeys refuse to work. They don't react to touch at all. They are lit up correctly by pressing other physical buttons but no function at all.
2. Power button refuses to work. I don't think it is physically broken because it works when smartphone is connected to the charger. It hardly works when phone is unplugged.
3. Screen brightness and other screen settings aren't saved after phone restart. Brightness goes up to maximum on phone startup even when setting up automatical brightness couple of times.
4. Phone refuses to be recognized as mass storage. Last few times I've tried to save some apks on SD card I couldn't do it directly via USB cord.
Phone was hard reset. I've flashed 2.3.4 V20S ROM via Smartflash - no change to the issues. Then I've made full wipe from CWM - no change at all.
Then I've flashed 4.0.4 V30B via Smartflash - no change as well.
I've Kingorooted Swift Black and installed Floating Soft Keys as a workaround for not working softkeys, but it is just workaround, no full function.
Any tips, clues?
EDIT: I've just installed eMMC Brickbug and run memory test with "Congratulations. Test Passed." If you believe that app the memory isn't corrupted, so why I'm still having 4 hard issues?

At 4.5 years, my thoughts are that you've gotten incredible life out of your P970! With hard and soft buttons failing, it's probably time to call it "done" and move to a newer phone. From what other users have reported, once hardware issues start cropping up, more are soon to follow. Anything prior to Android 4.4 (KitKat) is a security nightmare, and any hardware repair will cost more than a replacement phone.
I wish I had a better answer, but I don't.

Hi.
Thanks for the reply. I've just moved to new LG phone last christmas - G3, seems I've done it just in time
I'd like P970 to work just for general purposes of smartphone newbie: calls, sms and simple web browsing. Those are pretty hard with softkeys not working and screen wake up failing.
As I said about power button - it doesn't seem to be physically broken - it usually works - mainly when phone is charged - so that tells me that it's software problem.
Workaround for physically damaged button on rooted P970 wouldn't be hard. I've found instructions about remapping some functions to G button which was rarely used on my Swift Black.
The main problem is softkeys panel not reacting for any touch and I would be thankful of any good clue if it is possible and how to fix it myself without additional cost.

The softkey not responding is a bug introduced in 4.0.4 (I readed this in this forum). It seems there is no fix.
As a workaround I use Ultimate Dynamic Navbar, I prefer it over Floating SoftKey.
If you switch back to an older version of Android (2.3.4) , it should work normally.
As a workaround for the power button, you can change the G button to wake on your mobile from standby.
And try to never have to shutdown your phone (I think you can Power on the mobile by charging it, and disconnect the charger on the first logo (sometimes it work sometimes not, there must be a precise timing)
Also if you use your phone without LockScreen, you can wake it up with any button on the phone (G Key, Vol+, Vol- )

[HELP]Xiaomi Redmi Note 4X stuck at blank screen.

I have a Xiaomi Redmi Note 4X, which I started using around March. Lately, I have been facing an issue which has left me troubled a lot. My Note 4X seems to be in a bootloop.
Around two weeks ago, I was casually using my phone in college. I had put around 25 apps on download from Google playstore. Alongside, whatsapp was running. I usually take pics of my lectures, so when the teacher had written on the board, and was about to erase, I quickly attempted to go to the home screen, by clicking the home button ( middle button), so I could launch the camera app, and take the pic. But, the phone didn't go to the home screen, and stayed at the app being used. However clicking on the recent apps (the left button), the two running apps showed. However, as I didn't have much time, I did what came in my mind. Reboot the phone. Unfortunately, as soon as it booted back, the screen remained black.
Its been like this for two weeks now. Whenever I turn it on, It will show the Mi logo, then the Android logo simultaneously below it ( Like usual when it boots), but after that, the screen goes black. Touching the three buttons at the bottom of the phone make the back-lit underneath light up along with a vibration(Like usual). Clicking the touchscreen gives a vibration. If a sim card is put inside, and a call made to the inserted sim card's phone number, the phone starts ringing as usual, however, still with a black screen. Another major issue I experience other than the black screen, is that the top right of the phone becomes really really hot as time progresses( within minutes)(This never happened before), and the battery drains really fast too. I get freaked out because of this( I think it might explode or catch fire), so I quickly turn off the device, after some tinkering.
I have been trying to find a solution since the past two weeks. Hard pressing the Volume Up+ Start button takes me into MiRecovery 3.0, which offers 3 options, 1.Reboot, 2. Wipe Data, 3. Connect To MiSuite. Going into 2 gives the option " Wipe All data" only, and 3 is seemingly useless the MiSuite doesn't support new versions of Android. Hard pressing the Volume Down+Start button takes me to FastBoot. It should be noted, that in both MiRecovery 3.0, and Fastboot, the phone doesn't warm up really fast, as it does when booted normally, and rather remains cool even if left for quite sometime in these modes (approx 30 minutes atleast).
The main thing I'm trying to achieve is to backup the data on my phone, mainly the photos (lecture notes), and whatsapp data. The rest of the app-data isn't that much important, albeit if also savable, it would be a bonus.
I haven't tried flashing any ROMs, recovery, or anything else, as I'm afraid the data may be erased, and as I have never done anything like this before. Also, my phone isn't rooted, as I didn't feel the need for it to be.
Help is highly appreciated. I hope to be able to safely extract my data, and be able to start using my phone again.
Thanks to advance to all those who reply.

Guys?

Question Home button often not responding

Hi there,
My home button often stops responding. It will appear pressed correctly but doesn't actually go home. Sometimes the back and switch window buttons also don't respond, but that's less common. This happens about once a day.
The screen is fine as the buttons visually change to show I've tapped them, but they simply do nothing.
I can always fix it by restarting. It's only been happening on 12.1 v61 firmware.
There's no physical damage to the phone, it's in mint condition.
Any ideas? Anyone else having this?
I'm hoping the next software update fixes it because it's super annoying.
Thanks!

Global power management will cause erratic behaviors. A 3rd party app, does it happen in safe mode? Any apps installed or uninstalled before this happened?
Clear the system cache if you have this option.
