I started SuperPAD (deb-2.1v#3245) one day to find a "black" screen. Bricked??
Figured I would re-flash firmware 3245 and then install the Stragulus Android 2.2 update. Didn't take the first time, so I started all over by re-installing Android 2.1-v3245. Install was good, but now (beginning with the initial boot process) my screen flashes on and off continually. Using WindHex and IUW to re-install just about all the various Firmware’s available; nothing would keep the screen from flashing on and off, on and off, etc.
For some reason, I decided to change the "Brightness" level and "eureka"; when the brightness was reduced the flashing screen intervals increased and at a little less than half the brightness range the flashing stopped completely!!
Question is, "software" or "hardware" problem?
Comments towards a fix would be greatly appreciated.

Hello XDA,
I've recently purchased a samsung infuse and there were a few things standing out that i was wondering about. When i bought the phone, it had already been unlocked + rooted + flashed with S7, it should be running on the default kernal that came with S7. Afterwards, i installed dynamicRAM's tweaks in the development section.
1) Lock screen lag.
Wondering if anybody else is having this problem. When i hit the unlock button, theres a small lag time present before the screen activates, subsequently, when swiping my finger across to unlock the screen, theres a lag time before the imagine/slider/what have you responds. At first, i thought this had no functional problem and that it was just a little ugly. Until i received a phone call and in my attempt to answer it, the slider didn't respond. I wonder if this is perhaps a kernal problem?
2) If it is a kernal problem, is it compatible to try flashing the infusion 1.1 kernal overtop the default S7 kernal (Granted that the phone itself is first backed up with tibu and a NANDroid backup performed). Would this help the above problem?
3) The seller had the phone overclocked to 1.6 ghz with setCPU which isn't a large problem as its an ondemand clocking. however, the battery usage seems to be lower than expected? Note that i do not use data plan so thats turned off, wifi is turned off, but i like having the brightness as full (i acknowledge this eats up a lot of the battery).
Leaving the phone on my bedside table for sleep, it depletes 6% over the course of my 6 hour sleep. 1% an hour seems pretty fair. However yesterday, i unplugged from 100% at 2pm and used it till the following day 10 am. During this period, it depleted to 49%. I used aldiko for my book for an hour before bed. Sent a total of 14 texts, received 18. No music player was used, rest of the time the phone was essentially idle. I'm a little surprised at this.
I have yet to calibrate the phone but it is only a month old, granted it was calibrated after flashing S7, could this be the problem? I don't think the phone is undervolted yet, would voltage control from the market help this by lowering it a bit?
4) sometimes my volume slider just dissapears, i don't know why. Using the volume rocker on the homescreen usually has the ringer volume pop up. But once in a while, it stops showing up, the settings still work, but the slider is invisible. It is not restored upon reboot, and it eventually comes back and dissapears again.
5) First phone call has no audio. I believe this is a documented problem with S7, just asking to confirm this.
6) A couple of albums in my music library aren't tagged properly in the player despite being correctly tagged with MP3TAG on my computer. After some research, i think i found this is a GB media scanner problem. Is there a way to correct this? Perhaps take an apk from another ROM and replace it?
Many thanks to anybody who takes the time to read this thread
Hello.
I have one year the nexus S, and during that time I spent three or four times the following.
I turn off the phone and when you turn it lose screen brightness by 50%. And I have to leave at 100% brightness and do not know how to recover the brightness.
It has happened in different roms.
How could restore the default value without being forced to change rom every time I pass?
Which ROMs are they? Which kernel?
It has happened with these roms.
FASTEST ICS 4.04 03/03/12 Pixel Rom 1.60
Codename android (varias versiones)
CyberGR-MOD|NS.NGN ICS v.9 HYBRID+Matr1x 17.5
I have proven different kernels, which come in the roms and Matrix.
what about stock roms ? are you on auto brightness ? auto brightness always behaves strangely ...
I stoped using auto brightnes. Too annoying. . Stock user
Sent from my Nexus S
Once I had to re install the original rom ice cream to see if the brightness again. I got back the shine, but it happens again with other roms. Sometimes installing rom cuaquier recovers brightness.
The funny thing is, sometimes when I install the new rom, the first time does not recover the brightness, and i install the rom and it works.
Brightness What strikes me in both manual and automatic mode.
I try restarting many times to see if I recover the brightness and does not work. Yesterday remove the battery, and recovered the brightness.
It is very rare ...
Good morning every1,
I installed NeatRom on my i9100 and worked marvellous for months, now is a living hell! Not blaming the Rom itself but some kind of conflict between hardware and software.
Bug Description: screen strange behavior, in certain conditions won't turn on or will show strange colors, over illuminate or darken display, while at start up it will always work fine.
Trigger: locking the screen normailly causes to blackout but it will not turn on again on most tries, pushing the power buttom or the home buttom is equally uneffective most of the times. However, reseting the phone by removing the battery (since there's no display is the only way) will allow the phone to start normally: normal brightness, normal colors and normal operation everytime.
Fixes tried so far: I've reset the phone to factory, erase all cache, partition and delvik, and reduced the amount of apps to keep ram very low in usage. Also, I've removed the phone cover to check the screen connections, check the cable to see if its not broken and everything its fine. The display is not broken or otherwise damaged.
Opinion: since the display works fine at start up and would be working normally for as long as I don't lock it, I'm discarding all hardware problems of the screen itself; and I've removed all apps to avoid conflct of other software and it still has the same problem. Therefore, I think there's somekind of conflict between NeatRom and the screen (drivers maybe).
PLEASE HELP! :crying:

Hello,
XDA assist is for newbies finding their way around XDA Developers, it isn't a development section.
Please try posting the bug reports in the same thread you found the ROM in order to provide a helping hand to the developers.

Hi, I pick up my phone to check the time; i.e the time appears for a few seconds on the lock screen then screen turns off. I am using one of the round clock-face screens.
Sometimes (not always) when the screen is switching off, some of the content from my home screen flickers on screen for a fraction of a second (notification icons, the digital clock and something at the bottom), as white text on the black background. It's not catastrophic but it is enough of a flicker on the screen so catch my eye and make me look over at the phone.
Has anyone else seen this and/or know how to fix it?
Mine does it too, and I don't think there's anything we can do about it.
Which update are you running (1.15 or 1.21)?
I used to noticed a slight flicker on 1.15 not to the extent that youre describing, but it went away on 1.21.

I'm running 1.25.400.3.
It seems to be doing it less now, maybe only 1 in 5 times. I haven't changed anything (been running that version since I first got the phone last week).
Hi, I am currently on bit of a witchhunt with my V10 (H960A, running V30C-EUR-XX). For some reason the standby drain on this phone, which I bought used 2 years ago, is extremely high - about 60% in 12h. At the same time the on screen time is quite good with high brightness while watching videos I get around 6h SoT. Really bizzare.
One thing I noticed which is really strange is that when I change the display timeout in the settings to for example to "15 minutes" and I reboot the phone it always resets to the default setting which is "2 minutes".
So I would be really be thankful if someone could try this on their V10 and post the results.
Also I tried every trick in the book with this battery issue, from resetting the phone multiple times to running it in safe mode or flashing the Software with LG UP. Nothing yielded results. My theory is that something with the settings is messed up and keeps the phone in a "running" state while the screen is off.
