Touchscreen isn't working properly. - Xiaomi Redmi 3s Questions & Answers

Over the last year or so the touch response in the bottom left quarter of the screen has become progressively worse. And in the last 2 months or so almost unusable. Despite several taps maybe register once or twice. I have downloaded Touchscreen tester apps but I was able to fill all the regions completely in them. Also the Recents button is dead.
I have applied a tempered screen guard. Could touch be improved by removing it or its a lost cause?
The device has had several falls over the last few years. None severe though. Thanks.

Screen Accuracy Problems

The touchscreen on my titan is acting very problematically, with the screen slowly getting more and more inaccurate to touchscreen inputs, it's getting to the point where i have to use align screen 3+ times per day, and it's incredibly upsetting, is there any fix for this, or is it a hardware problem?
I'm not sure what it is but I too had that problem. After I flashed to DCD's 3.0.1 ROM,, the screen seems to be more stable. I still have to align screen every now and then. Do you you use your finger instead of the stylus? Sounds weird but I do that a lot and that might contribute to the problem.
Yeah, I do use my fingers on the screen a bit, with PointUI's Home, I don't see how that could cause it though o.o.
My I760 did that on two different phones. So i just got the xv6800, no problems yet except the ****ty video drivers-Or lack there of.
Okay, at this point the screen is going nuts, I'm probably going to have to send it off to sprint for a replacement at this point, as within 20 seconds of aligning the screen it's off by a good 5mm, and that number keeps rising.
Is you screen dirty? Along with using my fingers, my screen was dirty also. I just used a dry towel and clean the screen by blowing hot breath on it. Also, I bought new screen protectors. Yes it does seem odd that using my stylus and having a clean screen helped with my problem. Maybe my new ROM fixed the problem, I don't know. But its not as bad as it was before. Good luck.
Yeah, my problem was getting exponentially worse, off by about 6mm or so every time I'd align the screen, so I just returned it on my insurance plan.
Stylus vs Finger
If you are aligning your screen using the stylus and then using your finger for gestures and such the screen response is not aligned. You have to align with your finger in order to get a more accurate response because your finger covers so much more area than that tiny stylus tip.
I would alternate back and forth between the two, but to give an example of how severe the problem was getting, I would align the screen (with stylus) launch a program, and -already- the screen would respond about 4-5 millimeters down and 2-3 millimeters to the right of the stylus, which would make various tasks nigh-impossible.
I had the same issue and notice that it was mainly due to the fact that my screen was dirty as mentioned before. Sometimes you may even notice that your screen may not be dirty but remember that oils from our fingers and especially our ears when we talk can cause the alignment issues. Perhaps you can even change the screen protector and see if this helps. This should fix all of your issues assuming it is not an actual software problem. The one time that I did find the alignment to be a software issue, all I had to do to fix it was to callibrate the screen in both standard and panoramic view. I hope this helps...
Nah, it wasn't that, I tried cleaning off the screen with a microfiber cleaning cloth and everything, even removed the screen protector to see if that was causing it, it was a hardware defect.
Well I can say this.. I used to work for Sprint, Nextell, Verison, and ATT at various points. I know that with more of them, they usually send you out another device and you send your back. The think I love about ATT is that they will do this with a No Questions Asked policy except for the standard one involving abuse, water damage ect. After 3 defective devices, they will automatically upgrade you to another device.... Please make sure that the reasons are lagitimate so that this policy does not change but if you need to go through the hoops to get a better device that works.... Have at it. Do not take it to a store unless directed by the telephone people. Many people feel like they are techs because they own a ppc of some sort but they are not the ones that make the ultimate call. Let the corperate people make the decisions. Once you receive your device, immediately stress test it with all of the things that you will be doing with your device. Load and unload software, ect to make sure it works. If ther eis an issue, it ie better to notify them within the first 72 hours. I hope this helps again.

Screen problem... general bug or isolated device defect ??

Hi,
Does anybody else experience buggy screen more and more often ??
The first few days, i couldnt' unlock it for 1 second or so... was fine
Then after 2 weeks, screen got unrepsonsive for a few seconds from time to times.
Then 3rd week, screen was unresponsive for 1 HOUR... found out cleaning the screen or decreseasing screen sensitivity with BsB seemed to help.
And today... i wanted to scroll down in some program, it reacted as if i had another finger on the screen and started to zoom in or out.... 3 mins later : my screen became unresponsive and it s unresponsive now for the last 2 hours... cleaning the screen doesn't help.. it just doesn't react at all and phone is useless now.
Question is : Do you guys also noticed some decreasing screen quality over time ?? (maybe in some DIFFERENT ways than i had.... like this guy here : http://wmpoweruser.com/?p=10735
I am not able to do what that guy did on the video ! :/
Maybe you should update rom

Yes, I've had exactly the same problem for a few weeks - it's Summer here in Australia and I noticed the same thing happening when the phone gets hot while in use or connected to the charger.
It doesn't get better until the phone cools down. Believe it or not, I had to put mine in the freezer to unfreeze it. That's right, the freezer to unfreeze it...ah forget it...
I've tried several ROM upgrades and hard resets - makes NO difference. It's a device (not software) fault so you'll probably need to replace it.
Here's another thing you can try to see if you have the same problem as me - put a second finger at the bottom left edge of the screen and see if it presses soft buttons on the right hand side.

[Q] Anyone else have touchscreen problems

My phone last week wasn't receiving texts so I restarted it and when it came back on the touchscreen no longer worked. The little white light would go on when I touched it so it knew where my finger was but any movement would not unlock the phone so I couldn't actually do anything with it. Sure enough a factory reset fixed the problem but I am still waiting for them to get me a new one in case the problem happens again to me. Anyone else have this happen to them or just a freak occurrence for me?
My son has gotten a hold of my s4 twice now since I have owned it. Both times I couldn't get the phone unlocked even though the touch screen was recognizing my touch. Restarting fixed it both times for me. Not sure if this is the same problem you are talking about, just thought I would share.

Happened to me a few times. Both screen swipes and the capacitive button presses werent registering. Happened on lock screen, call logs (swiping to call wasnt working), and swipe to answer. Pressing the home button and going back to the app fixed it. Very random but annoying nonetheless especially when not able to answer a call
Seems like buggy software to me. I've had a different issue, my phone says I have data, but I don't, I've had to restart the phone to properly pick up a data signal. This has happened twice now. Seems to be like Samsung's touchwhiz is quite buggy...
Yeah restarting it did nothing for me, tried many times, took the battery out put it back in all that stuff. The same thing happened with my data, I had a connection that entire time that I was not receiving texts but none of them actually went through which is when the problem began.

What app were you able to get in to to fix it? Would like to know in case the problem happens again when they get me a new one.
This happened to me last night, about had a major freak out.
First I have a couple questions for all of you who had this issue, so maybe we can pinpoint the actual cause:
1. Did you get any type of moisture (even just a little condensation) anywhere on or around the phone? Mine started acting up after I accidentally put my phone on the coffee table where some condensation had formed from a drink being there previously.
2. Any of you drop your phone at all? Even just a minor drop...as the day before I had a little drop (maybe from a foot off the ground), but I do have a case.
The reason I ask is because I started having this issue immediately after the phone was put on the condensation. Don't know if that was the cause, though, because I'm not sure exactly which of the steps below actually fixed it.
First I had to identify the exact problem...which I found by turning on "show touches" in Developer Options within the settings menu. This brings up a little white dot on the screen any time it registers a touch. Sure enough, I was getting "ghost touches" on the top left corner of my screen every 30 seconds or so - and it would generally last for 10-30 seconds or until I turned my screen on and off (that would fix it temporarily). The ghost touch was causing my drop down menu to pull down slightly every once in awhile, as well as not registering any of my other touches (including capacitive buttons). I knew the screen itself wasn't broken, because any addition touches were registering via the white dot - they just weren't interacting with the UI.
After doing some research online, apparently there are a couple main reasons that this ghost touching could occur:.
1. Faulty digitizer. Obviously this would Suck, and I really hoped it wasn't the cause. To repair would mean replacing the entire screen, as apparently the digitizer is attached to the screen and would be very difficult to replace by itself.
2. Any kind of moisture, whether water, skin oil, etc, getting in the cracks of the phone and staying under the screen, causing the pressure to indicate a false touch. Possible repair options included putting the phone near a WARM (but not too hot) surface for a period of time to hopefully cause the moisture to evaporate. Also some people said it just evaporated on its own after a few days (again, I hoped I wouldn't have to resort to this as I'm impatient and don't want to be without my phone for that long lol).
3. Software issue. Possible fix includes toggling HW overlays and/or GPU rendering.
Here's what I did:
Took the phone apart completely, made sure there was no visible moisture anywhere (there wasn't). Intermittently blew the phone (from the back and front, while it was disassembled) with warm air from a blow dryer. Left it alone, disassembled, for about 30 minutes.
Put the phone back together, booted up, immediately went to developer Options and (a) disabled HW overlays and (b) DISABLED "Force GPU rendering" (I actually already had it enabled).
BOOM - problem was gone!
So like I said, I'm not sure which of those did the trick - or which problem I had to begin with - but I'd be interested to know if anyone else had similar issues and/or fixes?

I should not have had any condensation at all on my screen when it began. I was using the phone playing with WatchOn and setting it up for my TV, I was messing with it for quite a while and realized after a period I hadn't received texts in a long time (I normally get at least 1 every 10 minutes, I was going on a hour and a half with 0) which I thought was weird so I restarted the phone.
When the phone came back online I did not notice the white dot pressing itself anywhere, but anytime I touched the screen it would immediately know where my finger was and follow it around, but not actually press anything. When I held the power button and the little Shutdown and Restart options came up, if I sat there and just pressed either one of them constantly they would eventually recognize that I pressed something and do that action.
I was also able to get into the homescreen by getting the talk option to come up and backing out of it (The buttons on the bottom of the screen all worked fine) but once in the homescreen I couldn't actually press any buttons regularly so gave up on it.
The guy at the ATT store said he hadn't seen any other complaints about it so I did a factory reset while there (I had already backed up everything with Kies) and when it came back on there seemed to be no problems.
Like I said though I am waiting for a new one anyway, they are backordered at my local store (Should have got a new batch in Friday, not sure where my phone is now) so hopefully the new one I get doesn't have this problem nor the lag problem a lot of people have been getting.

Just the stock Phone app. My problem seemed like a software problem more than anything else.
But if you have to restart the phone in order for the digitizer to respond, thats a different story. A swap should fix your issue, since it seems so uncommon.

[Q] Touchscreen Randomly Stopped Working

Ok, so first thing's first. I've been researching this for a few days now before creating this post. The touchscreen issues I'm finding online, are similar to what I'm experiencing, but the solutions have already been done, or my phone is not responding to them. I'm making this thread to see if anyone else has experienced the same issues or has any new news before I a) return my phone to stock, b) replace the digitizer, or c) buy a new one or upgrade to the G3.
My G2 was rooted, but kept on stock ROM with only small tweaks here and there. After the latest update, I noticed my work G2 had much better reception, so I returned my phone to stock to download the update. After updating, I re-rooted the phone, this time, the only thing I changed was the keyboard which I replaced with the G3 keyboard. Everything was fine for months until about a month ago.
It started with not being able to pull down the notification shade on the right half. No biggie, but after a week or so, it got worse. While using instagram, I noticed that the confirm button was sporadically responsive. Sometimes it worked fine, other times it didn't work at all. It began to progressively get worse on an almost daily basis. I decided to see what was going on and enabled both input options in the developer options menu. I found that the entire right side, about 1/8" was not responding to touch, the area not covered by glass screen protector( i removed it later while trying to troubleshoot). The upper right area showed about a half inch block that wasn't responding (the area where the data ribbon is). I was ok with that as instagram was really the only thing I used being affected.
About a week ago, the mid left screen area started being errratic. It began to get worse and started to affect the front touch screen buttons ( the area where the other data ribbon is). I enabled the input options again and saw that I now had a good portion of my left side of the screen was unresponsive. Even though I didn't drop it, I thought maybe the data ribbons had come loose as those 2 areas are where they are. I opened and disassembled the phone and re-sat the connctions after inspecting them. I double-checked all the other connections and LDIs in case humidity was the culprit. Everything looked good. Didn't fix the problem.
I've had to set my phone to unlock by facial recognition to ensure I don't get locked out, and changed my pin to use numbers not affected. I'm going to replace the digitizer, but wanted to see if anyone else had the same issue, or knew if it was, indeed, a software issue before I spend $75 (I will be replacing the digitizer and LCD to get it working sooner rather than risk damaging the LCD while replacing the digitizer and having to wait another week). I don't want to send it in to LG because I bought it on ebay and have no proof of purchase for warranty, and I want it working sooner.
One thing I noticed that may help with diagnosing, the screen now looks different when off. Before, in direct sunlight, you could see the dotted matrix from the digitizer, and that was it. Now, I can see the retangular pattern across the entire screen. I checked my work G2 which I just received a few months ago and the rectangular pattern is only visible on the edges of the screen, the center is black with only the dotted matrix visible. Keep in mind, this is in direct sunlight. In shade, the rectangles are visible on both.
I'm hoping it's a software issue, but I'm wondering if the digitizer is starting to separate from the LCD. I don't see any acutal separation though.
Thanks for reading the book, and for any feedback. Also, because it will probably come up, I want to avoid upgrading if I can because the G3 is just a little too big.
I restored the phone to stock with the most up to date software. Still doesn't work. It appears to be a hardware issue. I really thought it was software because the dead spots word for a split second after turning on the phone. Oh well. Guess I'm going to order a new digitizer or LCD combo.

Edge Panel Sensitivity

I've had my S7 Edge for a two weeks now and LOVE it. I recently found a screen protector that works, too. Now, I'm asking the following question because I know correlation doesn't necessarily equal causation. But I only became aware of the following issue after installing the screen protector.
I've noticed that the edge panel doesn't always slide out when I swipe it. Sometimes, it's stubborn and it'll take a couple of swipes. I can't figure out if it's because of the screen protector, or an app I have Greenified, or something disable with Package Disabler Pro.
Any thoughts?

You are not the only one who has encountered this peculiarity. I too have encountered this without a screen protector, with a screen protector and again without a screen protector. This delay of the edge panel sliding out is around two to three seconds and always occurs only in the first instance; and fortunately I found your post.
Since a long time has passed since you posted and my response, I would like to ask you if you managed to solve this issue.
I have written an email to Samsung and am awaiting their response.
I would say this is definately your screen protector. My edge senstivity is perfectly fine, but as soon as I install a screen protector it really bad and takes a few tries to recognise touch.

The delay still exists even after removing the screen protector, as mentioned in my earlier post; just at the first instance. Is there any particular angle for the finger to swipe the panel handle?
Thanks.
Ur finger has to be at least 20 percent moisturized to trigger edge features. Make use of your body holes.
It could also be the amount of edge panels and complexity of said panels. For me i have seen as much as 2000 ms difference

I can't answer that as I've never had the same issue.
I guess I have remedied this:
1. I reset the S7 Edge.
2. Minimised to ten frequently used apps in the edge panel - earlier I had set up folders with many apps within.
3. Downloaded only Samsung created themes.
"Touch wood", I haven't encountered any lag while swiping the edge panel handle; past three days.
