[Q] Blank screen after boot? - Tilt, TyTN II, MDA Vario III Android Development

Good Morning all...
I've been running different builds of Android on my Kaiser since around October of 2010 and have yet to run into this one.
After initial boot and the screen blanks after 1 minute (what I have it set to do), if I try and press power (or "end"), the phone wakes to a blank screen.
I have not run into this problem on my spare phone yet but my assumptions are that the OpenGL driver is not being set correctly after wake-up. If I keep the screen on, everything is fine. Once the phone sleeps, it won't wake up. It does react as if the screen works because the phone will vibrate after holding power or end for a second or two. I can even get the phone to shut down, remembering where to press to shut it down, all with a blank screen.
Thoughts, theories, etc.?

Mods, please delete this thread. I have just about given up on any hope of a decent kernel for these phones.
Thank you.

Problem..Volume itself goes up. Please Help

I have a MDA 3. I am facing following problem..
- Can't power it off. Power buttom only works on powering on, but not on powering off.
- At the same time, the volume window pops up (with two volume sliders, "on", "vibrate", and "off), and the left slider automatically slides up on its own, preventing me from accessing anything else. When I try to do something else, go to Programs, or else, this freaking Volume window keeps popping up, and left slider keeps going up and stays up there.
When I try to decrease volume, it keeps going up right after I decrease it. And the volume window is almost constantly popped up.
From time to time, it disappears, allowing me to do something for several seconds or even minutes, but then pops up again.
Yesterday, I even managed to do something for several minutes without it, and even managed to turn MDA off, although I had to press the button for a second longer than usual to turn it off. Today, no luck, can't power it off. If I press it for a bit longer, it just goes in "dimmed" screen mode, but stays powered on.
If HR does not help, 90% chance that you have some hardware problem - stuck key, short circuit or broken connection from keys to the mainboard.

Phone no longer goes into standby itself

After 30 seconds or so the TP2 goes into standby, oddly mine doesn't anymore and I keep forgetting to turn off the screen and then running out of battery.
Any ideas?
Check your battery/backlight settings.
Hello,
i got the same effect.
I put the setting i.e. to 10 seconds screen off and 1 minute poweroff in accumode and 1 min. screen off and 1 min. poweroff. It wont be recognized by the phone. It stays on, with screen and device on.
At first I thougt it was some effect produced by the glight app i tested out, because i noticed this error not directly.
So i made a hardreset, but the effect is the same with the original htc rom without any mods, spl or some of this stuff.
any new ideas ?

Just a random thought:
If you're screen won't turn off, perhaps it thinks the screen is being tapped somewhere or a button is being pressed? If so, then you've got a hardware defect...
Ideas on testing this:
Create a new Note in drawing mode. See if any random spots/lines appear on screen. Try in both portrait and landscape.
Install the Rhodium Keyboard Controller. Add a new hardware key to map. If there's a key acting up, it should be picked up here.

[Q] Screen not starting up for power button

Hi,
I started to get a weird problem since last week. I've had this phone for about 3 months now and never had any problem like this.
It all started one morning when I wanted to stop phone alarm. The alarm was going off but the screen was black. I pressed the power button to wake up, but it was still black. After couple of times pressing the power button the screen came up. First it was not that often but the situation started to get worse. It came to that I can sometimes cannot turn it on for a long period of time. I need to keep pressing power button, volume buttons and eventually it will come up.
This is what I've found so far:
1) When the power button is pressed, although the screen doesn't start up, I can see the three buttons at the bottom lighting up. So it is not a problem of the power button.
2) When the power button is pressed, although the screen doesn't power up, the screen seems responsive. I can feel the vibrations when I tap (I have a startup password)
3) When the phone is connected to a power supply, screen always starts up without a problem.
4) Screen will start up more frequently when the batter power is high.
It seems as though there is a connection between batters power and the screen not starting up. But then again, once the screen comes up (after not starting up), then it works fine, until I turn the screen off.
Has anybody experienced anything like this before?
I did a factory reset thinking it might be some application I installed but it didnt help.
I had to send this phone once to repair the speaker and cost more than $80 just for courier. I don't want to spend another to get this fixed.
Thanks.
I have this problem or a problem very close to this. I have a HTC One X (international version). I'm running the latest version and updates and the problem has existed for at least the last two updates.
Android Version 4.1.1
HTC Sense version 4+
Software number 3.18.401.1
I have the screen lock pattern turned on.
Sometimes when I hit the power button, the phone does not turn on and so I press it again and only after a third press does the phone turn on. I then unlock the phone and use as normal. So, several times per day I have to press the power button three times before the phone turns on. But other times I press the power button once and it turns on straight away. I've just turned the pattern unlock off to see if this makes any difference. I'll start to record the exact details of when I experience this and see if we can work out a common cause.
Hopefully if enough people report this problem then they can send out an update to fix this problem.

I'm pretty sure this is a hardware issue. I bought mine from Expansys and sent it back to them for repair. It's been more than a month and they say they're still reparing it.
In my case it was impossible for me to start the screen up with power button no matter how much I pressed it. The only thing that worked for me was to press the back of the phone just below the camera. So it seems like a hardware issue. But on the other hand, at times when I can't get the screen turned on no matter what I do, I'd turn the phone off and start again and the thing would start up like nothing happened. So while I'm pretty sure it is a HW issue, I'm not sure how a power restart makes it work.
For me I don't think that this is a hardware problem as it only started happening once I did the big upgrade from 4.0 to 4.1 and then it follows a specific pattern. That is three power button presses will always turn it on. Less frequently I also get a problem where the power button turns on the three lights on the soft buttons but the screen remains black. I then hit the power button to turn it off, and again to turn it on and the phone is back to normal again.
Is yours an international version? I bought mine an international version and had it shipped to Australia.
solved?
Hi - did anyone ever solve this? This is happening to me with my HTC desire X after having had the screen repaired, so I think it is hardware related, but the shop doesn't know how to fix it! My screen also does not turn back on when I want to end a phone call and pull the phone away from my face anymore. These problems seem related as they started at the same time. I would be grateful for help!

[Q] Please help! Random power off won't boot!

Okay I will try to sum this up. My S3 was working fine and everything randomly I noticed issues with battery calibration It would be 100% then I would calibrate it and then unplug and then I'd instantly drop to 85%. Thought It was a battery issue and made a point to get a new one later. Then it kept working for another month or so then It started really screwing up the shutdown menu would randomly pop up and I'd back out of it.
Then randomly 3 seconds later the phone reboots. And it would keep doing that randomly I thought it might be a power button issue. Then as time goes on it got really bad to where it would simply reboot and not make it past the bootloader, It would not "reboot" more like a complete shutdown then I'd have to power it again and have it do the same thing. Seeing how I could not even make it past the bootloader I got a new battery, waited a week for it and then I put it in and the same issue happened. It would not get past the bootloader.
So I kept trying and trying and trying and it finally booted past that. And it stayed on for a whole night. I did everything on it I normally would and it was working great. Then the battery was getting low so I plug it in and was going to calibrate it after it was charged, I go back to it and it's dead again won't get past the bootloader once again. I'm completely out of ideas on how to fix this I pop'd off the button and blew in there and the button seems fine and everything still no change. I also can not get into recovery. It trys and loads but then shuts off. Anyway if anyone has any ideas on what this is or how to fix please help! I need my phone back! Thank you.
I'm running MOAR Lite version.
UPDATE: Took the phone apart and took a close look at the button it looks 100% fine...I saw a video on youtube that requires you to complete tear the button off and it works. But I don't know if the button is my main cause of this issue or if it will actually work. Some says it works, some says it does nothing...Please let me know thanks...
UPDATE 2: It will show that battery with spinning circle in it for like 1 second then turn off again. (When it is plugged in)
That's odd. But when it comes to the power button, dismantling and what not 90% of the time will show 0 issues. It will look perfectly fine when it's not. You playing with the power button I assume were pressing hard and normally to try testing it. It's a common issues on this version of the S3 to have faulty power button and you would need to get it repaired. Odly even slightly atmospheric changes can cause it to act different at different points. Some days it works fine, other days a very slight brushing over can cause it to screw up and trigger a manual shut down (holding for like 10 or 15 seconds).
Assuming that it is the power button, or to try, just do a variation of things to the power button itself. Use your finger nail to jiggle it around with different pressures. During boot if it shuts off, it could be the power button internally stuck, just jiggle it around.
This is all I can think of unless you bring it in to get repaired.
I was encountering the exact same problem. I would try to get into download mode and it would sit at the "Downloading" screen for about 5-7 seconds then the display would go blank. It won't make it into recovery either. Based on the above recommendation I took the whole phone apart and sprayed a lot of compressed air directly on the power button mechanism and the plastic case pressing the button in. I didn't see anything broken with the button when I did that.
It seems to be working now, I can boot into my Rom. Don't know how long this fix will last.

G3 VS985 difficult to turn on, recovery mode buttons don't work

My VS985 has 2 problems, which may be related to each other. The first is that, when the phone is fully turned off, turning it back on again is difficult. When I press the power button, the phone just vibrates at me and then refuses to turn on. Screen doesn't light up or anything. Pressing the power button again does nothing at that point. What I have to do, sometimes up to 7-8 times before it turns on, is remove the battery, wait a few seconds, put it back in, then press the power button again. It'll vibrate every time, and eventually one of those times it will turn on and boot up.
The second issue is that I've found it impossible to get into recovery mode using the buttons. I can get in just fine using the quick boot app, but that's not much use if I ever end up in a state where I can't boot into the OS. Apparently it's supposed to work by turning the phone off, then pressing and holding the power + volume down buttons and waiting for the LG logo to show up. I've tried this many times, it never works, possibly because of the first problem.
I bought this phone used, immediately used ODIN to downgrade it to the original stock OS, then towel rooted it and installed CM (LOS 14.1 now), so I've no idea if this phone has always had this problem or if I caused it. It's not a big deal since I always keep my phone on but makes trying new ROMs scary. Has anyone heard of this before, or have any idea how to fix it?
