Motorola Droid :: Light Sensor Or Timer Dims Screen Up And Down During Video Playback
Nov 7, 2009
I am not sure which is the culprit, but while playing back video or even at random times, the screen shifts lighter or darker seemingly at random, and one time during a video playback on the TV.com app, it went black altogether. I am not sure whether it is the timer or the ambient light sensor, but I am tempted to turn the sensor off and push the timer back a lot.
Been struggling with this since receiving my X. Seems like no matter what player I use the playback is jerky. It's very subtle, almost as if the video is dropping a frame or so every second. I've tried the stock player, Astro, Rockplayer, mPlayer, Zimly, Act, and the list goes on and the problem still persists.
I've encoded (using handbrake) with all of the settings suggested on the boards and have tweaked things on my own trying to find the proper setting, but still no luck. The strange and frustrating thing is that the exact same files play just fine on my 1st gen iPod touch (clearly an inferior piece of hardware) and on my wife's incredible. These encodes are of standard def DVDs at average settings (a full movie is about 1.3gb, all h.264 mp4 files.
I was able to improve playback by rebooting the X and then playing the video, but this doesn't seem like an acceptable solution every time I want to watch something. I tend to encode and watch a lot of stuff on my commute to/from work, and I'd really like to replace my touch with the X, but the media capabilities are falling way short. Considering switching to the Inc as I know it's able to play my media properly, but I'd prefer to keep the X for the larger screen size (though the Inc does seem to feel better when using one-handed). I'm on the fence right now, but if the X can't function as expected then it might be going back. Unfortunately I only have until the 1st to return it so I don't think I can hold out and see if 2.2 fixes this issue.
I've noticed that when viewing the screen in a darkened room that the screen is actually too dark. Yet in a normal setting that the screen is correctly lit. I've tried increasing the intensity to maximum with the sensor enabled and it's still to dark in the darkened room. Now, I've disabled the sensor entirely and the screen just runs wide open all the time - day or night.
Has anyone else felt that it was too dark in the darkened setting? I'm wondering if there is a setting (probably not yet written for the phone/OS) to vary how linear the light sensor is at darker levels? Maybe a 'minimum darkness' adjustment?
I have a HTC Hero here, and when I tried to get the list of available sensors on the device by calling ((SensorManager) getSystemService (Context.SENSOR_SERVICE)) .getSensorList(Sensor.TYPE_ALL); I get only the following sensors: D/SensorManager( 6302): found sensor: BMA150 3-axis Accelerometer, handle=0 D/SensorManager( 6302): found sensor: AK8973 3-axis Magnetic field sensor, handle=1 D/SensorManager( 6302): found sensor: AK8973 Orientation sensor, handle=2 D/SensorManager( 6302): found sensor: AK8973 Temperature sensor, handle=3 According to the specs, there should be a light and a proximity sensor on the Hero, and I've seen it in action (the automatic screen brightness adjustment) - so at least the ambient light sensor is definitely there. My question is then, why doesn't the getSensorList return for me the light and the proximity sensors?
So I'm using NexBeast v1.1 on my Droid and noticed in the clock app there is a brightness button that dims the screen even further (similar to the bedside app I'm guessing). Unfortunately the screen dimness only lasts while in that app. I was wondering: is there a way to set the overall phone brightness itself that low or keep the screen that dim outside of the app? The lowest brightness in the Droid settings is still a bit too bright for me.
I have milestone for 3 days good phone,camera performance surprised me expecting worse but...when i am making call display turns off and non of buttons work even i can hear ringing or person who i call then i have to slide phone slightly or fully to switch display-phone on.it wasn't working since the beginning but when i installed task manager it was working properly almost one day,next day again bad.the same story after hard reset.
Question about video playback. Do you have to convert everything to .3GP ? I drop some movies onto the SD card and play them just fine. Then went back to play them it was REALLY choppy. Not exactly sure what is causing this. I would rather not covert everything to a different codec.
I took a few videos over the weekend and when I played them back on my phone, there was a bit of jerkiness, in each video. When played back multiple times, it jerked in the same spot each time. I don't remember if I was running Stagefright or not when I took them, maybe that is a variable.
The Droid can only play MPEG-4s right? If not what's the best format to rip movies to? I tried MPEG4 720X480 and the phone never even saw it on the SD card. Unless I'm doing it wrong (like music, I just created a folder called videos) A certain Tarantino film just leaked and I really wanna watch it during my commute.
I just received a micro hdmi an wanted to know what is the best settings for just connecting my DroidX to my tv to watch dvds? Do I skip the converting process altogether an just make sure that the video that I burned from a dvd can be played with the Droid X media gallery while connected to hdmi? I have converted some dvds (Super Troopers) for optimal playback on the Droid X but when I watch that video through HDMI it really isn't the best quality. I have used DVD Catalyst.
I've read through the deluge of threads that have sprung up since Friday's Droid release. However, I have only seen this issue listed within longer conversations about frustrations. I wouldn't call this a frustration as much as I would a quirkiness of the Moto Droid that I'm hoping some similarly-annoyed person out there has developed an app to overcome this.
The issue is with the screen lock and the auto-dimming on the phone. The first issue with the lock screen is not a device-specific issue as far as I can tell, but it is insanely annoying not to have a lock timeout setting within the OS. I should not have to unlock my phone every single time the screen dims from the timeout setting. Every other phone I've ever owned that has a screen lock does not have this limitation and, if someone were to mention that the iPhone has the same issue, I would point out that they suck.
As for the other issue, and the far worse one, how in the world is the proximity sensor when on a call so damn finicky!? I have read this complaint multiple times on various forums, but no concise list of solutions. The screen goes black when you have the phone to your ear, but when you move it away from your ear, the screen should *consistently* re-light so the user can have access to the keypad, etc.. This is not working at all as I would expect. I did find an app in the marketplace that allows you to set the screen timeouts by application, but if I set it to not timeout on the phone app, the screen will stay lit when I have the phone to my ear, which would defeat the whole purpose.
This seems like a huge bug to have missed in all the testing that occurred before releasing the phone, especially for such a basic feature. I expect customers to go nuts on Verizon for this one (my fiance is far from a technical user and has the Droid and has yelled at me to "fix it" referring to this problem..
Due to the multi-tasking capability of the DROID, you can fire up MotoTorch LED to have the LEDs on and then fire up the camcorder for some low-light video recording. Works okay for what it is. I don't think MotoTorch LED fires the LED at full blast like when you take a photo, but it works decently well.
After the OTA and a factory reset my screen dims when I tilt the the phone in camera mode. It's fine when the phone is vertical but when I go to take a horizontal landscape shot it dims the screen to black. It will do the dimming proportionally to the angle the phone is rotated off the vertical axis and front to back (freaky) It will still take the shot but I have no idea how centered I am on the shot. I changed auto dimming to "off " but it still blanks it.
It seems like my droid will only go to horizontal orientation if I turn it counter-clockwise. When I turn it clockwise, the video plays in landscape by upside down. I'd like to play it landscape turned clockwise and be able to access the charging port while watching television. has anyone found a video player that is capable of this?
i wonder if anyone have had this problem? very choppy video playback on the milestone, in terms of fps and audio lag in the video. no matter wat video player i use, its stil laggy. is it because of the new maintanence update by motorola last month, cos i dun seem to have such problems before. can someone pls help me? its a very irritating problem.
I'm having some troubles with the light sensor on the Nexus One.
AFAIK, the proper way to read the measures of a sensor is registering a SensorListener through the SensorManager and then wait for the readings on the onSensorChanged method.
My main problem is that the light sensor don't seem very accurate (the readings jump a lot) and I don't get the first reading until the lighting conditions change. I have to change the phone orientation, go outdoors or hide the sensor with my fingers or otherwise I don't receive any value. Is there any way to increase the accuracy or, even more important, to force an initial reading?
BTW, I have tried with SensorManager.SENSOR_DELAY_FASTEST but I haven't noticed any change.
Just curious it says that the phone supports MKV files but they do not play with the regular player. I do have a program to convert any video format to MP4 and have done that and it plays no problem with the default player. I've seen in another thread with the droid 2 it can play AVI's? What formats does the phone play? What player is the best that supports the most formats? For my computer I use VLC and that is the best damn player there is for my PC.
When you talk on the phone in Android the light sensor is working. If you cover the top left corner of the screen, the display turns black and you can't see anything. I would like to cancel that feature and I tried working with Android Sensors and the Light Sensor but it is not working. This is my code:
I've got an HTC Desire from a T-Mobile store 3 weeks ago. The ambient light sensor has never worked and it's enabled on the display settings.
I went back to the T-Mobile store and they tried a brand new unit. Unfortunately, that one also seem to have the same issue. Then I called the HTC technical support and they say there are no reports on such kind of issue.
If not, does the display brightness get adjusted quickly or slowly?
Have an Issue. Whenever i am in a call if i take the phone away from my ear the screen doesnt turn on. It does this 98%of the time or only when i need to use the keypad during a call. It does this in stock form and also using open home. I always keep the screen clean. Is there a fix for this? I am not able to get my bh2 to connect to a pc so i cant root or install custom roms. Also the keyboard lag is rediculous. I tried better keyboard and it was just as bad if not worse.
I am writing a program and I am able to get the light sensor value and current battery level, but only the light value changes and when the battery level changes. Is there a way to get these two values anytime? Like when a user runs my program, I would like to grab the current values right away instead of having to wait for them to change.
