[Q] Rooted phone, screen stays blank when unlocked?

It has done it for a while with any ROM, the screen backlight will go on, and the button lights will go on but the screen picture doesn't show half the time when I unlock it. I can still touch the screen though and it works, but obviously I can't see what I'm doing! This is frustrating and could be terrible in an emergency... What should I do?
Also, when my headphones are in, and the phone detects it as a headset, it will spasm out by turning on voice search, and ringing people repeatedly until I unplug them, it also changes song too on any music app. Any way round this one too?
Thanks

No I didnt that I know of... How can I check this?

Which rom are you using, custom or stock...We will need more details as it can be a setup issue...

Using LeeDroid, but its done the same with Android Revolution and I think MIUI too. I think it could be something to do with the CRT animation but I'm not 100% sure
Edit: I have turned off the animation and the problem is still there

Speaker problems

Hi, since two days, the external speaker, the one with which you listen to the music, he started to not work. I feel terrible sound, cracking and buzzing, like when an earphone is wet from the water ... I cannot solve this problem (not a software issue to me, although I hope I am wrong). What should I do? Changing the speaker? If yes, how?

Take to service. What rom are you using? If MIUI4 then this is normal, otherwise service only.

I'm using Sandvold's ICS for Desire Beta 0.15.0.1 with evervolv turba kernel.
So, I must fix this acting on hardware? Just to do one test, now i'll try to switch ROM, maybe a Gingerbread one.

Yep. I changed ROM, changed sound settings.. whatever I did it still don't work. I opened my phone, i gave two knock on the speaker.... and now it doesn't work at all .
Searching on the web, i found this: http://www.htcrepairparts.com/speaker-bigback-for-htc-desire-g7-p-3229.html and next week i'm going to try to replace with a new speaker by my own. I think is the only way ^^ (cannot take it to the service, warranty over).
Thanks for the replies! I'll post there the results!!

news
The piece has just arrived at the post office. Tomorrow I'm going to retire, then I will see if I can replace it by myself, otherwise I will contact some friends
From that site web (http://www.htcrepairparts.com/) it tooks 25 days to be shipped to Italy.
Bye!

bad news
I've just replaced the speaker with the new one, but... nothing has changed.... the sound is exactly the same as before :|
I'm investigating further on the device right now, hoping to find something wrong around the speaker placement...

bad end
Nothing to do.... i check around the speaker, cleaned some parts.... but the sound remains the same. I'm going to download some app that can set maximum speaker output at about 80% (it seems that at this level the sound is pretty good).
Close.

[Q] Screen Glitching, unable to unlock etc.

Hi,
I am experiencing some really strange problems with my phone. I have a 2-month-old HTC one X. I have never dropped it, it has never been in contact with any fluids or damp areas, also I have never tried to unlock and/or root it. It started two weeks ago. The screen started glitching and behaving weird. Sometimes it would stay for an hour, sometimes it was just a few seconds.
(sadly I cant post outside links, but if you search youtube on "HTC one X screen glitch" and than scroll down you will see a video uploaded by DjStasV. Thats what it looks like. But instead of only glitching on a small portion on the screen it was always the whole screen.
But now, it has gone one step further. Sometimes my phone won't unlock if I press the on/off key. The soft keys light up, but the screen doesn't. I can even get called, the phone will ring and vibrate, but I can not pickup because the screen doesn't turn on. For some reason it sometimes does unlock, but I have not been able to discover a reason for that. Also when I manage to unlock it, it sometimes just freezes (the screen). The phone still works (it rings, the notification LED works, it vibrates), but the screen is just frozen. (also a reboot by holding the power button does not work 9/10 times)
I am hoping someone will recognize this problem, and maybe even know how to solve it. Thanks in advance

Thats impressive, air is a fluid.
It sounds like a hardware fault.

Yes.
Gas and liquids are both fluids.

In common usage, "fluid" is often used as a synonym for "liquid". But ofcourse, you are right
OT: Thanks for the quick responses, I will check at the nearest HTC service center then

[Q] Screen does not turning off during a call

Hello everybody,
my girlfriend have an a Sony xperia s and for awhile when she having a phone call
and put the phone against her ear the screen does not turning off the buttons are been pressed
by her cheek, this causes a lot of embarrassment when the call is disconnected in the middle of an important call,
most of the time the button just pressed and the other side just hearing an annoying tone.
this is annoying and i don't know how to help her with that.
is there any good solution for this problem?
i tried to look for this problem in the search engine of this forum
and all i found was the same problem but in HTC phone that runs Windows Mobile, that didn't helping me...
thanks for anyone who can help me with that...

Try rebooting/resetting.
If problem persists then the proximity sensor may be faulty. Take it to Sony, coz it's a hardware problem.

Perhaps her phone is dirty, so the sensor won't work.. You know women, they don't care about technology.
Clean the screen left next to the Sony logo real good

My first opinion is hardware issue. It can be said that the proximity sensor is faulty. My second one is software. maybe she install a program that uses or control the proxomity switch that causes it to malfunction having a conflict with other programs. My third is that, as early as possible if its hardware issue, go now to sony service center for them to figure it out, use your warranty card, that may cause no additional problem right? Smile!

You could try re flash the firmware with flashtool

i think that maybe it is an hardware issue,
she don't installing any application just by her self, and she don't have many apps.
i know almost every app on her phone (cause i have them also on my SGS4) and i don't think that the apps are the problem.
but i will look for an app problem anyway just to be sure before using the warranty.
thank you guys...
UPDATE:
i've checked the phone sensor with the new app cpu-z and the app shows that the sensor is working and identifying my hand
when i covering it.
but still there is the problem that the screen does not turn off when she's holding the phone against her ear,
i've watched while she's talking in the phone and she's holding it as it should be.
but as i see the problem is not happening in every phone call but it is happening a lot.
any idea how to solve this problem?

No notification LED after MM update on ZE551ML?

Maybe it is just me and my device, but since the MM update (the real one, not the beta) my notification LED doesn't work. I have tested it with text messages, emails, missed calls, charger plugged into my computer, charging plugged into a standard charger, and charging plugged into the fast charger... nada on any of them.
Anyone having this issue? If so how have you rectified it? It has been a minute since I first got this thing (got it at launch) and the MM update reset all my settings so maybe there is a setting to turn it back on I am missing?
Help out a brother if you can. Thanks.

OK, so does anyone have any suggestions for an app that might help by letting me manually setup the notification LED?

Thanks for the reply. It is not in DND as far as I can tell (not on).

If you haven't already, try a factory reset first

Actually yes. After I wiped my phone for my wife the notification now works.
Another issue that I recently found the solution to... if your ZF2's proximity sensor has gotten crazy sensitive since the update try cleaning it. Seriously. Especially if you have a tempered glass screen protector. I thought the piece of advice was bogus but I cracked out my lens cleaning spray and cloth and BOOM, the proximity sensor works correctly again.

Thanks! Got the led working again after a factory reset.
By the proximity sensor do you mean the little one next to the selfie camera or the GPS?
After a lot of fixed I've got the ZF2 working fine, except for the "smartlock - safe places" that thing can never work right.

Sorry, I just realized that you had replied.
Yes, the one beside the camera. Many have had an issue where the screen goes black after you start or answer a call, especially after the update. It seems the update made the proximity sensor much more sensitive. Since all decent screen protectors have a small cutout for the proximity sensor it will tend to accumulate dirt and oil from your skin. Wiping it down doesn't seem to get it clean enough for the sensor so you have to get a little more aggressive to clear the problem up. I went months enduring the problem and even set my phone so I could disconnect from calls using the power button and then ended up stumbling over the solution when setting up the phone for my wife when I upgraded to my Axon 7.

No led indicator
Hi i've been experiencing the same issue. After I update my zenfone 2 ZE551ML 4gb/64gb version, I have noticed that the led incator is not working and it is not found in the settings. Also, another issue I have encountered is that quick charging feature is not working sometimes but sometimes it works. I don't know how to fix. I'd be glad if someone could help with a step by step process. Thanks in advance!
