Xperia Z3 vibration issues

Hi Guys.
Greetings from Ireland. I have an Xperia Z3 D6603. Its running stock Andriod L 5.0.2 with Apex launcher instead of Xperia home. Its a great phone and besides some small issues I love it. The main issue however is that it randomly stops vibrating which can be quite irritating. It started acting up about a month ago and I presumed it must have been an app causing the phone to misbehave, however when I boot the phone into safe mode the same occurs. Usually from boot up it will work for about 10 key presses, for eg the home button pressed multiple times and then it stops working. Then after a few minutes it will kick back in. This is most noticeable when typing and is annoying. Its like the motor gets tired and cuts out if that's even possible? Anyone else had a similar issue? I searched but couldn't find any applicable information.
Thanks in advance,Barry

...

the lag could be from the launcher and its eating the cpu and thus when typing its slow to respond to the touches, have you tried it with the stock launcher?

Hi Richy. Yeah I booted into safe mode and the same occurs. I thought it was the launcher or a third party app but in safe mode if I repeatedly tap the home key for 10 times the vibration disappears. Really has me confused, I don't see how it could be hardware when the motor actually does work when it wants to?

I have EXACTLY the same problem. It is super irritating and I have the feeling too that it's a software problem. Maybe something that the previous software update is causing. It even just happened when I typed this. Maybe someone has a clue?

Touchscreen issue (bad grounding)

When I put the device on to any insulating surface such as pillow/bed/couch/table I cannot normally operate it. Touch is being interrupted very frequently. This means in practice that I unintentionally press links while sliding through web pages, it is impossible to organize icons (since icon is dropped quickly), pinch-zoom is difficult, unlocking the device is hard, when text-typing it often doubles the letters etc.
Problems goes away as soon as I plug the charger, or take the device in my hand. This looks to me like a grounding issue, which was annoyingly present in some of OnePlus One and Nexus 7 devices in the past. Desperate users were hoping for a software update to solve the issue but it never came out.
Is anyone else experiencing similar problems with Mi 4c? I also tried flashing different MIUI versions, nothing helped.
Here is a video demonstrating the issue (you can enter hardware test menu by calling *#*#64663#*#* and try it by yourself):

I tested, mine is ok

I never really use my phone that way but out of curiosity, I tested it. Can confirm, issue is there. Touch screen goes crazy when scrolling facebook posts, chrome browser, possibly anywhere until I lift the phone up.
Just noticed that I needed to tap and scroll up/down harder than I used to otherwise I would miss it and the scroll would stop halfway through and will tap on whatever it is on the screen when it stopped.
Basically when I don't tap hard enough when doing the scrolling gesture, that's the time that the touchscreen goes crazy

works proper at my mi4c

I had the exact same problem. It is a defective screen. The problem started appear for me after 3 days of use, so I returned it to the store for an immediate exchange. I am not sure if you are in China or not, but if you are, you can just walk into the store and get a new one on the spot.

for me works perfect

Works ok on mine

Works fine here...

I can't even get the touch test started, running cm12.1, dailing *#*#*2664#*#*does nothing, as well as no other I've tried tested

Try it with some app. For a single-touch this one is just fine: play.google.com/store/apps/details?id=com.tsaysoft.touchtest
It draws a continous line and if you lift a finger (or if you have faulty screen) the line disappears.
To test a multitouch function you can play with: play.google.com/store/apps/details?id=com.the511plus.MultiTouchTester

Thank you, I'll try those.

Mine is working as expected as well

found solution(the grounding problem is still a thing but this makes it less of an ass)
1) root the phone or just use the developer rom from xiaomi
2)then install Pimp my Rom from google play and grand root
3)go to tweaks-> touch-screen & display-> multi touch amount
and put it on 5.

Hello,
Yes. As a proud owner of one (unfortunately defunct cause I dropped) nexus 7 2013 I can confirm that the behavior is the same... Definitely a grounding problem.
When you leave the phone on a pillow or couch without holding it,bthe screen response is erratic. When you hold it or attach charger.. No problem.
Still beautiful device (the 4c), especially for the price. Snappy.
And smiu is very good made. (not a fan of miui roms...)

This happens only on 16gb version? What about using a plastic case? Does it solve the issue?

Xperia XZ firmware 41.2.A.7.8 – keyboard issues!

Hi guys!
I've updated to 41.2.A.7.8 but the one bug I hate the most on this device is still here on Android 7.1.1 – some of the keypresses are recognized as a straight swipe line when typing fast and thus Swiftkey keeps assuming wrong words. This happened as well on all past firmware versions I’ve tried.
You can easily check this behaviour by entering *#*#SERVICE#*#* on your dialer, choose Service Tests, then Touch, then Free Drawing test, and then pretending you're typing (both thumbs) at high speed.
This is even more evident when you are using Stamina mode, and more so in the more aggressive Stamina options, which leads me to believe it’s processor dependent. Xperia X also had this very same bug but was corrected with firmware updates so… come on, Sony! Stop screwing things up!

It's an issue with Sony moving to swiftkey as stock. Sony's own keyboard worked much better on older versions, you can still use it on Nougat, but it's a bit slower in touch response. This is why I use Gboard. If I could disable predictive engine in swiftkey, I wouldn't mind using it that much, it's annoying and I hate that blank bar above the keys, uses up the screen space. I also don't use gesture typing in any form, so the old stock xperia keyboard was always my favorite.
Ditch swiftkey, try something else and see if it's better. The issues people describe with keyboards in 7.0+ are non-existant for me. Or at least disable the gesture typing in swiftkey settings. But still, the predictive engine makes it laggy and glitchy, even though it is by far the best predictive and gesture keyboard out there.
The free drawing test isn't really a good measurement here, it's for drawing lines, not tapping. Use tap test and you'll see no matter how fast you tap, the digitizer registers taps. When you tap on the drawing screen and manage to tap a single pixel without touching the next one, it will stay black, it looks like it didn't register a tap.
The keyboard, and the entire UI in general, being laggy and slower in touch response while using Stamina actually makes sense and is completely normal. It lowers the screen refresh rate, the touch responsiveness and the framerate of the rendered content.

No it is not. This is an issue with the way touch screen inputs are processed, regardless of the keyboard you are using.

It isn’t better. Every other keyboard behaves exactly the same when the wrong inputs are interpreted.

That is even worse because when you disable gesture swiping, right to left (wrong) swipes are interpreted as deleting the previous word.

When these touch screen issues were solved for Xperia X, you got perfect typing behavior even when Stamina mode was on.

I don't see the keyboard issues when using gboard or atock xperia keyboard, although the stock one is a bit slower in response, so I don't use it.
The way it behaves under Stamina seems normal to me because it's how my ex z3 and z5 behaved and it makes sense. The performance of the phone is reduced, ofcourse it will be less responsive and laggy.
Not until we recieved the swiftkey, I havent seen this issue.
The way they "fixed" the tapping responsivness on the X was by not using so restrictive and conservative stamina profile, it didn't reduce the digitizer responsivness as much. It's a battery saving mode, after all, you can't have both with equal efficiency.
I'm sure they could do the same with the xz, but it would mean affecting battery life as well well.
Free drawing test makes no sense if you are testing tapping speed...
Or are people complaining about swipe input? If that's the case, than drawing test would be useful. For normal tapping on the keyboard, I see no issues.

Looks like you haven't even actually tried the Drawing Test yourself...
Some of the taps are recognized as a straight swipe line when typing fast and so this problem will always be present regardless of the keyboard software you're using.

Can anyone check this is still present on 41.2.A.7.35?

I have tried the drawing test when I read the post, also the tapping test, otherwise I wouldn't even engage in the conversation.
The lines in the drawing test do not appear on my unit, when I tap quickly on the drawing test it doesn't draw these huge lines.
Does this happen in normal mode as well or only in stamina? Cause I didn't try in stamina.
I'm on Customized CE 41.2.A.7.8, and the device is rev.1

You have to type even faster
This happens in normal mode as well as in stamina mode, but it becomes much more frequent in Stamina mode - in fact it becomes more noticeable the more aggressive the Stamina mode chosen.

I was tapping as fast as I could, faster than I would normally while typing a message.
But I guess I'm doing something wrong or I'm just a slowass typer so I don't see the issue.
Good luck eith yours, I hope you solve the issue or Sony fixes it.
Maybe start off by doing a full software reflash to a latest version released today? See if it helps maybe...
Cheers

I have the same issue. And I don't know how to solve it. Except without gestures.

I have full screen gestures enabled and no issues with swiftkey(beta). On what rom are you? I tested it with chinese stable and xiaomi.eu

Doesn't matter if I push the letters or just swipe, no lag at all. Maybe you can test the swiftkey beta app or disable spellchecking in input settings

Hello again
If I disable de voice comand, the problem persist.
I downloaded the beta and, the problem is the dame.
I Dont understand. If I disable the full screen mode, its solve the problem
Im not alone with this problem

new info and seems to be solved.
I keep in background the swiftkey app, the lag disapears

this not solved all the problem but minimize it for me
I launch de app of swiftkey, after this i enter in multitask screen. Keep pushing the app of swiftkey and apears a lock (if the lock is close, the app allways in background)
After this the lag reduces a lot

I'm using this phone since three days ago and I immediately noticed this issue, and it is specially annoying when I try to use swipe writing. I suspected that occurs because the system doesn't know if your are trying to write using the keys located at the edges of the screen like q, p, etc. or just using gestures. In consequence I tried to adapt the keyboard using the one hand feature (Google keyboard) and putting it in the center of the screen and it worked, the lag disappear. I'm attaching a screenshot because my English sucks. I hope you can see this way what I did.

I tried turning on 'Show virtual keyboard' in Settings > Languages & input > Physical keyboard, and it seems much better for me now.

I have already reported to MIUI team but while they do something about it, i've installed Edge Gestures to replace full screen mode, to hide navbar i've installed Navigation Gestures and finally AutoNotification for hidding apps in background notification. I have lost gestures animations but works perfect and the only issue it's volume bar in landscape like the image attached.

This is a nightmare and makes the device horrible to use.
I reported it to MIUI team weeks ago. The best solution for now is disable vibration on keypress within Google Keyboard, which makes it way less noticeable.

I'm using miui 10 weekly on eu roms, the problem is still there...

I'm on xiaomi.eu 8.8.3 and it seems like it has been solved through software update. I no longer have the issue testing in sketch app, or using any keyboard with full screen gestures.

Xiaomi Gestures and gesture typing

I have gestures enabled on my mix 2s and I love them. So much more screen real estate to play with. However I find they interfere with gesture typing (eg: Swype or Gboard). In particular the 'p' is very difficult to swipe when a word starts with it. Anyone got a workaround for this? The MIUI back gesture (swipe) from edge really should only apply to the top 2/3 of the screen.

I also experience the same thing. I've just decided not to swipe close to the edge when typing

Does your keyboard closes while typing? Could be because of this: https://forum.xda-developers.com/xiaomi-mi-mix-2s/help/miui-im-swiping-t3803874

Excellent work around thanks!

This is by far the most annoying thing I've come across with this phone! Strange. I tried the draw app test rapidly tapping between the sides and got so many false swipes it was crazy. Hopefully the sensetivity can be adjusted in a future update. Xiaomi seems to be pretty good with updates so far.
