Dpad-right button unresponsive

Hi ppl. I have a problem(and I think,not just me) with Right arrow/way underneath the display. It is absolutely unresponsive very often,suddenly it works normally. It seems,that the touch sensitive surface has an unstable pressure threshold in this area. It is very annoying,so knows someone any solution? Thanks in advance.

I have exactly the same problem, really annoying it is. Cannot play games with a right arrow that works half the time

Try to blow in centre button.

try this, use left thumb to hit the right button. Its really annoying, it seems the left right cursor pad it too sensitive and must be pressed at the correct angle

I'm also having this problem.
Do you guys know if it's a hw problem or it can be fixed with one of the custom roms?
Thanks

No, I only found this thread. I didn't find anything in the wiki either.
Thanks for those links.

Oops! .. I thought it only happens with me, there might be some problem in my phone, as it felt down from 6 feets just after 2 days from the day I bought it.
well it's really annoying..
hope to get a solution. (I think the hardware button is not manufactured properly).. (I might be wrong )

I have the exact problem!!!
Does anyone knows where to buy a replacement keypad??? I have been searching for it for days now with no luck. and all I could find is this one http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=120488502946&ssPageName=ADME:X:AAQ:US:1123 and this one https://www.gsm4world.us/htc-touch-...rane-pcb-repair-d-03019_405.html#remote-tab-1 and both have the same price almost $50.00 for a couple of buttons. have anyone found it cheaper???

Have you tried the HTC debug tools to see if the navipad is registering touches in that area?
http://forum.xda-developers.com/showthread.php?p=2511016
You'd be looking for the 'NavDbgTool.exe' in that zip. Just extract the whole zip to somewhere on your phone and run NavDbgTool. You should see some lines and dots moving around on your screen. If you are able to see the lines moving when you move your thumb, it would mean that your navipad is working just fine.
Try running this program when you're unable to press the left or right buttons and see if you get different results.
My guess is that the buttons are just fine, but where you are putting your finger isn't exactly where HTC thought it should go in order to actually 'press' the left or right buttons. If the sensors and underlying buttons weren't actually working, you wouldn't be able to press end call or back either.
Hope this helps!

If you are new to the phone try those suggestions above. If this has just recently started happening when the phone used to work fine, its broken. The capacitive sensor HTC put in is junk, I had mine break 2 times. Got it fixed through warranty. It is not a software issue, you can hard reset, change ROMs, etc. It won't fix it, it is physically broken, and you can confirm it with the NavDbgTool.

[Q] Snowy screen

A few weeks ago my Sensation screen turned to colorful pixel snow. After opening the sense lock ring and flipping the main screen for a few times it became ok. A week later it went back to the snowy screen permanently.
I went to recovery and re installed the Rom (revolution 6.80) and the problem was solved. A week later I got the snowy screen back, but now the snow appears the very first moment the device is powered on.
Due to the face I had airdroid on the device I managed to connect it to the computer and see the mobile screen on the computer and it looked as if everything is ok, I could see the sense and all the screens and operate all the applications by looking at the computer and touching the snowy screen.
I bought a new screen and connected it instead the original and I still got snow....so I know it's not a screen problem.
I do not have warranty on the device and local labs will charge half the price of the device for fixing it, so I prefer to find out what's the problem and but the parts myself and replace them.
Anyone has any experience with such a problem and fixing it?
Thanks a lot

Try using a blower, those that people use to blow off dust, blow off every spec of dust you can see on your device, clean the connectors of the screen too.
Then, try installing a rom which is not ARHD, and test it out. If all these doesnt work, it might be your GPU hardware is faulty.

I already cleaned all the connection and checked that everything is connected correctly but it didn't help.
Do you know where the gpu seats? maybe if I knew what it looks like i could check problems around it or replace it.

No one knows how to solve the snow problem? :crying:
That's it? the device is dead? I used it only for one year...

Can you take a photo of it and post it?
Then we know exactly what you're talking about

wow... I've never seen anything like that before. Hopefully someone else can help

maybe the connector of the lcd panel is disconnected a little bit.

I bought from Ebay defective Sensation, it has exactly the same problem.
Did you find what you HTC was wrong?

I'm also having the same snow problem on my HTC Amaze, for the above i assume there's no fix to this as i was about to purchase a new screen.
This phone is a complete lemon so perhaps it's a blessing

Seen that 2 days ago at a friends phone. No solution oder fix for that?

Cases can do this, and rear screen protectors that cover the flash can too.

Why "of course"?
Post some example pics, perhaps it'll be clearer then.

Yeah mine did the same on the weekend, I wasn't sure initially if it was the flash or a bright light off to the right of my shot, so I turned the flash off and the issue went away confirming it was from the flash. What is happening here is that the ISO sensitivity is was too high with the flash.
The best way to combat this issue, is to set the camera settings to manual, and keep the ISO as low as possible to get the shot

Here are some extreme examples, the first with flash ISO800 the second with no flash ISO3200.

Those having bleeding problems l, it coupd be to do with light bleeding under the back panel, I smashed mine and got a replacement and it happened to me. The back panel was not secure so I reapplied it and now it has gone.
Just out of interest try putting a bit of pressure around the lens when you take a shot and see if the problem is still there.

The same happened to me now, got the bleeding after it was repaired in a store.
How did you make sure, the lens is secure? Just by pressure or did you heat it or added extra glue or something? :silly:

[Q] Graphic problems with p5100 10.1"

Hi,
I got this weird problem and im not sure is this a hardware problem or not. For example. when using menus with white background, the background goes partly blue. Sometimes the graphic error is only blue lines in some part of the white background.
but when checking one option in same menu the background turns normal or atleast there is some change in the background. So these errors reacts only when changing options. And theyre always in the same position when going the same menu.
Also when using camera. the view is messed up a bit. there is a clear line somewhere in the picture when going dark to bright. With my english its hard to explain especially when i dont have any idea what is causing this problem.
Below are two attachments that explains the problem much clearer than i can write:

}
And before you ask. Yes, it has dropped and i have replaced the glass. But i got it with broken glass so i dont know was it like this before it dropped and the previus owner couldnt tell either.
Any possible solutions?
Thank you in advance!

Sounds like a hardware issue, just for the heck of it I would open it up and check the ribbon cable to the digitizer/screen, it could be loose.
Pp.

Checked it. Same problem. Tried to change brightness level, hard reset, rooting etc with no luck.
Its just so weird that in some situations the screen looks totally normal. only these few situations cause errors in the screen.

Hmmm, there are dialer codes that are used on phones that run a series of tests to check screen performance and output, don't know if this can be done on a tablet, but I would research it.
The only other time I heard of this was on a phone that recovered from falling in a toilet, the phone was dismantled and cleaned and assembled and it worked fine for over a year, the only glitch was an occasional color spasm on the screen similar to what you discribe.
Pp.

Thanks for the tip! Need to look for those codes when i get back home. I removed the logic board and cleaned it with denat. alcohol. No visible damage at least! trying to assembly it back later today. I decided to order a new LCD flex cable. Its the cheapest part to change.

No luck with the codes i found. after cleaning still same graphical problems. Now i can only wait the new flex cable and hope it will fix those errors.
Anyways thanks for replys and suggestions. :good:

Help with a probably fake Mediacom tablet

Hi everyone, I need some help with this tablet I got a couple of days ago and that I'm trying to fix. I just need some opinions from someone that maybe already had an experience with such a problem or someone more expert than me. On the back it says it's a Mediacom tablet, but I don't think it really is... It says "SmartPad 7.0 S2 3G", however the model number written below says M-MP7S4A3G, which is the model number of the SmartPad 7.0 S4 3G. And this thing doesn't look like a SmartPad S2, it's black and doesn't match the pictures of the product from the manufacturer. It also has a clean Android ROM in it, without any Mediacom customization or app (maybe someone replaced the ROM... I don't know... but that model number discrepancy doesn't convince me).
By the way it runs quite well, and I would like to keep and use it, however it has an annoying screen flickering problem that shows up and increases its "blink-rate" the more I use the tablet. If I put it in standby mode and let it cool down, the problem disappears, until it gets hot again of course (please note that I'm just guessing when I say that the screen flicker is related to the temperature, it could easily be another kind of problem). The flicker also appears in recovery mode so I think it's hardware-related.
When it occurs, the colors quickly change and then come back to the correct ones, with a variable frequency that seems related to the temperature (again: just an assumption, better to say the frequency is related to "how much time you have been using it", from what I can understand). I can also see horizontal lines when the blinking occurs. If I keep using the device, after a couple of minutes, the wrong-colors state takes over. If I'm viewing a black and white page the problem isn't noticeable.
I opened the tablet and tried to move the display connector, also disconnecting and reconnecting it after cleaning the contacts, but without success. I also tried quick-freezing various parts of the board with liquid nitrogen, but that didn't affect the blinking (this is why I say that the relation between the flicker and the temperature is just an assumption... I mean, I cooled almost everything under 0°C and it was still flickering).
Then I read online about people having screen flickering problems after software updates or ROM changes, so I'm a bit confused. Do you think that this problem could be software-related? Maybe the display drivers in the kernel are messed up? I would really like to flash a clean ROM but I'm not feeling good about that, I don't know what device this really is... On CPU-ID it shows an MT8312 platform, but the MediaTek Flash Tool identifies the chip as an MT6582 (uhm...). I'll attach a couple of pictures of the device with the CPU-ID screenshots. I'll also attach the screenshots from a genuine SmartPad 7.0 S2 3G that a friend of mine has (they're the ones taken with a camera capturing the tablet screen).
So I'm asking a more expert person, how should I proceed? Maybe I can backup the whole MMC and try to flash something? What ROM should I flash then? Or would it just be a waste of time because it's certainly hardware-related? If so, is there something I can do with the board? Maybe I can try to reflow the SoC or the display controller IC (in case it's not integrated in the SoC) with an hot-air gun?
Any suggestion will really be appreciated. Thank you very much in advance and sorry for my english if I made any mistake, and also sorry for the long post.
