My wife's P7510 has started to act up. The touchscreen is jumpy. When i go into the development options and use the pointer coordinates option, my finger registers as two,sometimes three. It makes it difficult to type, and just hard to use. Do i have a hardware issue or is it something I can easily fix?

Did you flash another ROM?
if stock: there is maybe moisture or dust, take apart as much as possible and hoover round the edges,If the touch screen is still not working, the tab is broken as the majority if touch screen phones and tabs cannot be calibrated
The tablet is still under warranty, so I don't want to dissemble. It had rooted stock OS on it, ICS. I flashed the stock rom back, and still have the issue. Did a Factory reset, and still have the issue. I am in the process of draining the battery to see if that helps. But I was hoping someone may have had this happen before, and can shed some light on my problem.
well, if you still got a warranty claim it then

Try using the touchscreen tune app (requires root).
This will allow you to modify screen sensitivity and test.
If you have the warranty..backup your data and claim a new one.

I don,'t think this app will work as this looks like a hardware issue after flashing another ROM, maybe you can check the all forum-searcher and check if anyone else has this issue too.
I'd suggest to send it back and claim a new tablet as well!

Iv seen that with the OG evo also, as well as my 3vo
Having the same problem. Probably will carry it in next week for replacement. Already took it in once and they said wait for a couple of weeks to see if HTC/Sprint release a software update. It's starting to get very annoying and unusable. Very much ruining the experience of having a powerful smartphone.
i have it too with my gsm version , the upper part of mine screen is sometimes not responsive

i wonder if this is related at all to the screen grounding issues which they originally had in the HTC EVO. the end result of the screen grounding issue was parts of the screen were unresposive...
i do remember they patched something in an update which fixed that issue.
i remember there was a test for the screen grounding issue but i barely remember how it worked. i'm sure there are older threads on it as it was a fairly big deal when the device first came out. the test had something to do with drawing lines or something on the screen?
might not be helfpul, but figured it was worth mentioning. i haven't had any issues on my evo 3d so its hard for me to troubleshoot and compare...
at least replacing the phone will be a decent solution until we can find out more about this issue ... sad it seems to be fairly common.
I am having an issue with my phone not reacting correctly to the proximity sensor. When I am in call, the screen shuts off when I put the phone to my face like it is supposed to, however when I remove it from my ear the screen doesn't come back on. I tested the sensor with an app called sensor list, and it is without a doubt working correctly. I have a custom kernel installed. Could that be causing my issue, or is the software just bugged?
Stock, rooted, unlocked, what Rom? Info would be a good starting place.

Stock rom, debloated, rooted, and incredikernel beta 6.
I ordered a new digitizer to replace my mildly scratched one and would like to replace the prox switch while I have it apart. does anyone have any clue where I can get a replacement? Or better yet, what is the exact switch I need. I have an old d1 somewhere, can I Frankenstein that into my rezound to make some abomination?
I recommend testing the sensor itself to rule out whether it is a hardware of a software issue. There are many proximity sensor tester apps in the Play Store.
Edit: NVM, it looks like you already did test it. Disregard this post.
This is what part the Elixir app reads on my Rezound; the phone hardware revision B rather than XA if that has any impact (likely not for this simple part, check under the battery to make sure you have a B model phone if you wish):

the op was from a while back, I have since got my sensor to fail the test. Thus I will replace it. I don't want to send my phone in only to be received by someone in a bad mood who will charge me 650 bucks for unlocking my bootloader. And they will send me a refurbished device that will probably have more problems than this one.

Despite the fact that nobody has actually had that happen yet???
So you will void the warranty instead... so if you really break it, you don't have no repair option at all.

This makes more sense... but even then there, it is not 100% you will get a refurbed unit or that you will have problems with what you get.
BTW, my stock unit doesn't turn the display on when you take your face away from the screen. I always have to press one of the volume keys to get the display back on (easier than reaching the power button)
My display stays off as well. Does not seem hardware related to me.

I have already had this phone apart and the little green void sticker is already gone.
I guess if everyone is having this same issue, it must be a design flaw. I doubt I will correct it by changing the sensor. The screen is supposed to come back on when you remove the phone from your face, unless that's a software bug in sense.
The real question is does it work in 100% stock Gingerbread no custom anything. If it does work then it could be a app or the kernel if it doesn't work then its hardware.
How is this such a hard concept for people to grasp?

If you look at my op I was on 100% stock gingerbread other than a kernel. If everyone has the same problem, yes it is hardware related, but it is a design flaw. It is unlikely that everyone who posted has a bad proximity sensor.
Yes I did read and as you just posted your not on 100% pure stock. You said stock rom, but never said stock ics or gingerbread but like I said best way to test is go 100% stock no mods at all and even go the route of no extra apps, it may seem extreme but its crazy all apps that can cause issues.

Here is the real question. Does your screen always go off when you cover the sensor. Mine does not. I have to try several times, and when it finally does turn off, it only sometimes comes back on. other times, I have to press the power button. Who else is experiencing this?
Mine acts as if it had no proximity sensor at all. Programs say it does, but it always reads that something is zero cm. away from it... power button is the only way I've found to turn the screen back on.
I bet a lot of HTC phones have this issue. When I searched the number for this sensor, a lot of their phones came up as results. I think we are all running bugged hardware.
Curious to know how many other people are having issues with their proximity sensor while using a AOSP rom. I have been using Antp's "le n00b" (lol) AOSP CM9 Kang and have been having issues with my device locking up during calls. So I started to investigate more into the problem and have tried multiple fixes, nothing seems to work. I've took it a step forward just to determine whether my proximity sensor has just recently gone bad. I restored my backup of Venom and walaa, my sensor is working normally. No lockups, or any misbehaving. Only thing I find weird is some people have the issue, and some don't. Many factors come into this, I know... But my screen would only lock up if I was in a room with dim lighting. When I was outside in the sun, worked smooth. Would really like some feedback on this if you guys don't mind. Thanks!

I've got this problem too. I don't have to be in the middle of a call for my phone to freeze though. I checked with the Android Sensor app and it doesn't toggle between 0 and 9 (cm? I don't have my phone on me right now) like someone else reported. I have to turn off the screen (which takes a few seconds after pushing the power button), and then when I turn it back on the phone works normally.
Another detail I found though is that even though the display "freezes", it still accepts input. If the screen freezes, and then I press the home button, when I turn the screen off and then back on, I'll be on my home screen. Not in the app that I had running. Same with the other cap buttons, keyboard, on-screen buttons. If it was an issue with the proximity sensor, I would think the screen would just turn off and not accept input, right?
The ROM isn't at fault here, it is a hardware issue of the sensor getting dust in it. Simple as that.
Yeah, it's not Rom related. It's definitely a hardware issue and if your still under warranty I would take action ASAP. My replacement should be here tomorrow so crossing my fingers its problem free.

Well it may not be ROM related, sure. But I don't think it's a physical problem with the hardware either. luis, you said yourself when you restored back to Venom your 'sensor is working normally' and you had no hiccups. I didn't have the problem under CleanROM DE either.
Maybe the problem is in dmeadow's kernel. It is beta after all

It's happening on Venom for me now. Only difference is I can hit power button to get my screen back.

Ah, damn. Alright, maybe it was just an unfortunate coincidence that the timing for when this started happening matched up with when I started flashing the newer ROMs/kernels.
Different ROMs detect it differently. It IS a hardware issue.
Found out how to disable the sensor completely. Testing it out now. So far so good.
Edit: Sensor disabled and sticks after reboot. If anyone with sensor issues wants this mod, pm me. I want someone else to test this out.

The proximity sensor in this phone is a problem. Mine wasn't working at all, so I got a replacement. Got it and set it up yesterday and this one works....kinda. It works mostly correctly in bright light..outdoors, in an office, etc. It doesn't work correctly in low light...at night, in my house, etc. However, I can make it work temporarily by rubbing my thumb across the top of the phone over the Verizon logo for a few seconds. That will make it work for between 10 seconds and a minute or so. It seems to be IR/heat related, as even in bright light it sometimes needs help. I think I might just going to disable this one and deal with it.

Yeah, these sensors are horrible. Its not a show stopper, but it does suck to have these issues with a device we paid good money for.
Sent from my Xoom using xda app-developers app
Question to those who have done it, how far do you have to tear down the device to get to the sensors? Are they attached to the motherboard or are they in the display? The guides and videos I've seen revolved around replacing the display/digitizer, and I haven't been able to tell exactly where the sensors live.
Sorry luis! I went to sleep between my post and your post so didn't test last night. I'll flash it right now and get back to you on whether my display freezes anymore while I'm out today.

I had my first freeze up already. I checked with the Android Sensor Box app and the proximity sensor is still registering values (0 cm if I cover it, or 9 cm if I don't, no in between).
I just bought my Z today and am having a few issues with it. First, the automatic brightness doesn't work. That is if it is turned on/off from the menu bar it does not work at all. If it is changed within settings the brightness does change to a certain level and that's all it does. Second, the tablet is extremely slow installing some applications. I have owned many different android devices and never experienced the absolute slowness this tablet has when installing some apps. Not all apps install slow, but I had one take over a minute when it should have taken about 5 seconds. And finally when using the browser, the touchscreen becomes very unresponsive when downloading and installing applications. I try to scroll by swiping the screen and sometimes the tablet just completely misses seeing that input.
Edit - I tested the auto brightness some more and it does work, it's just not as sensitive as some other devices I am used to.
Edit2 - I think the slow install could be a bug with the custom skin Sony uses on top of the o/s. It's sometimes getting 'stuck' displaying the install message.

If you've just bought it today and you haven't too much stuff on it I'd try a factory reset and try again. I have had three different models of Asus tabs (all rubbish), still have my original galaxy I/O tab (great for its age) and I can honestly say this is the most fluid and rapid tab I have seen.... That includes installing apps which as soon as I started using it caused me to remark how quickly it downloaded and installed from the play store.
Auto brightness is also sensitive and rapid on my unit, to the point it annoyed me at the beginning cos i thought it was too sensitive...
If that doesn't work maybe your unit is faulty

I returned the 16gb model and bought a 32gb instead. I think the auto bright is just less abrupt than I am used to, but it does work. The only problem I am having on the 32gb which I did not have (or notice) on the 16gb are the 'phantom touches'. Twice today the tablet went into the settings all by itself. I'm going to research this issue more....

Hi guys!
I bought the Z3TC LTE and are very happy with the device but I experience kind of ghosting with the touch screen:
Moving my finger up and down on an scrollable page / app it starts missing or skipping a movement!
Is that a general problem or should I return the device?
I made an demonstration Video:
http://youtu.be/EUeAt1HMt-w
try a reboot.
is it only 1 app or is it happening on different apps?
Reproducible in every App! Reboot does not help!
If I find time I'm gonna try the same on an Z3TC in an local store..
hmmm thats strange....
glove mode is not on right?
If not, try a factory reset.
if that does not work, sounds like service.....
does this happen when you are charging the device? sometimes this is caused by a charger that doesn't supply sufficient current

I think I am facing the opposite of that. The screen is far too sensitive and sometimes takes a scroll as a touch. Happens everywhere on the device. I fear it's a hardware thing.
