Weak/no vibrate after rooting - Xperia Z3 Tablet Compact Q&A, Help & Troubleshooti

Yesterday I rooted my UK SGP612 without unlocking the bootloader. It took a while to get done, but eventually got there and I now have a rooted 4.4.4. The only problem is that haptic feedback seems to have mostly disappeared in the process.
What doesn't work:
Vibrate on touch doesn't work
Sony keyboard vibration doesn't work
What does work:
Google keyboard vibration works
Soft nav buttons vibration works
Test vibration in diagnostics works
Swiftkey vibration works, but only if I increase the duration from the default 10ms to 50ms
I'm fairly certain it all worked prior to rooting, but even a factory reset and a reflash of the kernel has failed to fix it. One thing that did catch my eye is that in the settings for the google keyboard the intensity can be set and this defaults to the system setting, which seems to be 0.
UPDATE: I just found that the Sony keyboard also works, but only if I crank up the intensity to almost max.
So does anyone have any idea what might be causing this issue and how to resolve it?

[Q] Vibrate problem

Hello everyone at XDA
Got this problem with CM9, didn't really notice it the first week when i installed it but now it suddenly came to me that the vibrate function didn't work when i receive a text message.
This is some info:
Running the latest FXP216 (xperia sola)
Every tiny option that has vibrate in it's name is turned on.
The phone does vibrate if i have the "keyboard vibration" turned on so it's not a phone problem.
The messaging app itself is:
Notifcations on
vibrate: always
vibrate pattern: normal (no difference if i change to average or large)
The profile settings (from the notification bar) don't make a difference either (in vibration mode etc)
Reinstalled CM9 twice completely and wiped phone clean, no difference.
Spend 3 hours today googling for options but no luck.
Don't mind using a third-party app (tried SMS Go but it doesn't vibrate either)
hopefully someone can help me to make it vibrate when receiving messages ;D
Thanks for all the helpfull threads so far.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
FIX: finally got it to work after even more googling.
Sound Manager V2 has a vibration option which can be set to always (at ringer sound)
This solved my problem, hopefully people who have this problem can find this helpfull

[Q] Stock 4.3 Text Alert Vibration

Hello
Now my phone is working again properly after the stability update I still have one nagging little issue.
Is there any way to make the vibration for text alert longer like it used to be before in 4.1.2.
I now only get two little vibrates and they are easily missed if in the pocket. Before it used to give a long single vibrate.
I have tried all the settings I can think of and find but cant seem to change this ?
Thanks

[Q] Extremely Weak Haptic (Vibration) on Touch Elements

Hey guys,
I've recently swapped my Z2, from a carrier locked; to one that's unlocked from Sony. Trouble is, the unlocked Z2 seems to be defective. The haptic feedback is super weak, to a point I can't tell if the motor is working. The thing is, if I perform a repeated action, such as tapping the back button (furiously), the vibration motor will then pick up momentum and start to vibrate properly. I've compared the two Z2, and the other Z2 (locked one) is performing as "expected".
So far, I've two areas/actions that are lacking in haptic feedback; typing on the stock keyboard (even though I've set the vibration duration to the default level), and the navbar buttons (back/home/recent) give a very very faint feedback.
I've ran several tests, including the ones from the service menu; and those worked wonderfully; the device would just vibrate right away. The device also has no problem vibrating when receiving phone calls or texts.
Just how many different vibration motors are in the phone? What could be causing weak haptic feedback?
in the Z2 there is 1 viabrate motor to my knowlage,
it seems your device is defective and id recomend you try to get a replacement
the exact problem seems like the motor is stiff, or over magnitised of sorts

I have exactly the same problem with my UK unbranded Z2..Haptic feedback works perfectly on all diagnostic tests, phone ringer, notifications and alarms, but only intermittently with stock keyboard, Swiftkey and home buttons.
I think its a software problem, I'm going to flash the .402 German firmware later today to see if that cures the problem...If not it's going back to Amazon.

I just flashed the .402 German firmware and also did a 'repair my device' in PC Companion before flashing, and the haptic feedback is still weak, not functioning properly and erratic. Must be a hardware issue.
I'm returning the phone for a replacement.

[Q] [4.4.2] Screen does not turn off after a reboot! Not with power button either

This is the single most frustrating bug I have ever encountered, within a month on two different phones. I was using a Galaxy SII running Kitkat ROMs and this bug occurred on each ROM - and I've just bought a Lenovo S860 which was officially updated to kitkat yesterday and now this same darn thing just happened again!
The bug: After a normal day or two's usage a simple reboot results in the screen/display staying on permanently. It does not respond to the Power button at all - although the power button works perfectly if I need to reboot or power off the phone.
Each time the only solution I can think of is to factory reset which is so frustrating. I don't know why this bug has happened to me on two different devices now; the common features I can think of are that on each phone I had Developer options enabled (but 'keep screen on during charging' unchecked) - I use Dynamic Notifications as a primary lockscreen. I keep display timeout at 1 minute. Other than that I use a few very standard News/Productivity apps none of which have anything to do with keeping the display on and rendering the power button useless.
Lenovo S860 that I'm currently on is not rooted and is full stock so I haven't tinkered around with the system at all either.
I would appreciate any help, any hint or guidance or just plain anything. I'm literally afraid to reboot my phone now, I can't keep setting up the phone after a reset every two or three days.

disable vibration

Stock no root access... I want vibration turned off completely, whoever thought vibration in a tablet without a way to globally disable it was smoking something really special, I'm sure, but it is extremely annoying (and sometimes even unsticks the magnetic keyboard case)... I've individually turned off as many vibrating notifications as possible but it still vibrates sometimes... Any advice please ?
I wouldn't mind disabling it too, it's pretty loud too.
