Crazy touchscreen while USB in use - Sony Xperia M4 Aqua

I would like to ask if someone else experience crazy touchscreen behavior while your m4 aqua usb is in use, be it charging or data transfer. Its impossible to type, as it type at random or close/open almost every app or menu. But once I remove the usb cable it works proporly. I have a glass screen protector, but I really don't see how it would be connected with this misbehavior.
OS: 26.1.B.3.109, locked bootloader , unrooted.

touchscreens work by closing a circuit between screen and your finger..when electricity passes through cables it creates a magnetic field..what type of glass screen protector are you using..link to it?i have one too but i haven't got any problems like these

Sorry, I had to put a generic one [cheap chinese], as I couldn't found any branded in my local market. Though I just tried and it was working just fine with 100% battery, maybe its related to the a low battery state. Will try later.
Thanks for the repy.

[Q] Touch screen problem

Hey there
So I changed my Xperia Neo's panel as carefuly as I could
I turned it on but the touch screen doesn't seem to be working although the ligh sensor is functioning properly and all the buttons but when I press the screen it doesn't register the touch could I have broken something or might this be some other reparable problem? :crying:
Thank you for your time.
I found the problem - I've cutted the cable of the digitizer :/
I would like to advice unexpirienced people like me to be very careful when replacing parts of their phones, watch for the tiny cables
Regards!

"Feel" your Prime charging!

I found this by accident but thought it was an interesting thing to post (hopefully no one else has posted this)!
While charging (with dock or via tablet itself), rub the back of the tablet with your fingertip(s) back and forth. You can unplug the tablet with the other hand and notice that the vibrating feeling goes away (so it's not the texture of the device!). Make sure you don't touch the tablet with any other part of your body or else it will neutralize the effect.

I also had that, try to change the direction of the power adapter
This is a known issue by Asus. They suggest you flip your charger over and that will go away. Just another poor design...
And it works, thanks!
This happen on my Prime and on my MacBook Pro too.

Pretty interesting. Thanks for replying. Is there a reason behind it? Poor grounding?

There is nothing wrong with the design. but there is something wrong with your home grounding system. If you do have a grounding system, and your charger have a grounding feet, it wouldn't happen.
To be honest, most chargers don't ground these days. My UK official prime charger just has a plastic pin for it's 3rd ground pin. Nothing to do with your home grounding when the charger doesn't even ground at all.

indeed . this is just a design flaw.
btw this stuf happens with the tf101 too.
yeah, Also .. with a 3rd party charger touching the screen causes multiple touches to be detected --
Android detects lots of touches and the cursor leaps around - If I hold the metal case it stops.
Took me ages to work out what was happening.
Not sure I can reverse the wiring on charger.
I also have a DELL laptop ( L521x) that is highly charged -- touching the metal case will create a tingling.
it stops if I plug an audio cable in
Happens on my tablet on the top of the keyboard ...where the connector is... my tablet has a Skinomi full body skin...so I don't feel it on the tablet...... and its in a case....

[Q] Is the magnetic charging port REALLY that dodgy?

There has been multiple threads on XDA developers about the magnetic charging port falling out of the device and im start to regard buying a dk36 charger.
I want to ask a few question in regards of the use of the magnetic charger and how you think it came loose in your device:
How did you get the magnetic charger to attach to your device? did you just let it clip in with the magnetic or did you have to apply force to either the device or the charger to get it to start working?
With the use of the official magnetic charger (dk36) did you just let it clip to the device or did you have to apply pressure to the device to get it start charging once it clipped in?
How did you remove/ dismount the charger?(kinda stupid by hey)
And how did you fix the problem/ RMA the device?

I have been using mine for the past month and nothing loose, nothing falling apart. The magnet is not that strong.
Mind you, I don't swim with my phone so I don't know if it has become less waterproof or something like that, but definitely, the port sits tight, it is rigid and no problems.
I've been using the magnetic charger since my Xperia Z1, and never had problems with it coming off.
Same here have the official magnetic charger past few months and no problems what so ever.
I've got a cheap Sony knock off magnetic USB cable. Works fine.

I went to a Sony Centre to confirm if the cable is a knock off or not and their answer was: "This is a Genuine cable, but it's not available in your region."
However this cable doesn't have the "build week indicator" so it has to be a knock off, right? 0.o
Anyway this "Sony" magnetic cable gives me a headache. Genuine or not?
You can't apply force to make contact with the charging port(on Sony docks) the magnet is what pulls the contacts together(phone rests on dock).
I've been using magnetic charging docks from day 1(3mo ago) until a few weeks(when my port quit working) and it's still firmly in place(wish it would have fell out instead of failing so at least I could fix it myself).

it seems only older models of the Z2 have alot of issues, only new ones seem not to have these majour faults
my freind has a brand new Z2 and i said you wont like heating issue yet he says he doesnt get overheating while playing games which i feel ls a lie because i had heating while web browsing and this was extreme heating, something not as heavy as a highly detailed graphicly intensive game
but newer Z2 quality apears improved, you can see proof across xda :/
i think sony may have fixed the magnetic port issue in the newest manufactured models :/, its glued in in old but lets see about new?

When was his z2 manufactured may i ask ?
Is there a post about which batch of z2 is faulty ?
and the overheating issue is eh for me because i dont game on my phone, i mostly browse reddit, websites and social networks

he claims his batch no. is 14w30
-He claims the folowing:
no heating issues
no camera shut down
no random bootloops
no squshy button issue
no faulty camera button
no flaps issue
no random data loss issue
mine was 14w20 (i had a 14w17 device before sony gave free replacement)
and i had all issues mentioned above
heating (no camera shutdown ever oddly)
random bootloops with no mods
buttons werent clicky at all
camera button sometimes never worked
my flaps wouldent stay closed
my entire device would wipe its self for no reason
list goes on
lol im glad i dont have any phone right now xD
Mine is 14w18 and no issues you mentioned above (except device does get hot after prolonged use under the sun).
I'm wondering is the magnetic charging port falling out due to a really strong magnet on the charging dock/ module or is it falling out due to heat or applied force ?
I assume the official charging dock dk36 would have the "correct" magnetic strength to not ripp out the magnetic port of the phone
I've been having a lot of problems with my magnetic charging cable. When I first got it (from Amazon), it worked great. Connected easily, and charged wonderfully. Now, it seems loose and wobbly, and I have to set it the right way so it connects. Tolerable if setting on table to charge, but in the car or while holding it is frustrating.
I have a 14w19, and have been having overheating issues at times, and 1 dead pixel, and not rooted.. Should I try for a replacement?
well my official dk36 just came in so yeh lets see how thing goes and if its faulty or not

[Q] Magnetic Charger Concerns

I've ordered the Z2 and it should be coming to my door any day now. When I realized that a magnetic charger might be a good idea to prevent wear of the microUSB port I started to look at the options available. Unfortunately the charging dock sold by Sony is too expensive in my opinion and I would like to find an off-brand alternative. I've looked through the posts on this forum and have come to understand that putting the charger in the wrong direction could be a big mistake. I'm still willing to buy just a cable but would prefer a dock to help prevent this.
My questions is does anyone have a suggestion for a dock(preferable) / cable?
I found this cable on amazon:
http://www.amazon.ca/gp/product/B00...pf_rd_t=101&pf_rd_p=1947489602&pf_rd_i=915398
PS: A lot of docks on amazon have some bad reviews and I'm wary of buying them
I was in the same boat. The Sony dock looks nice like but it was fairly expensive.
I just ordered this last week:
http://www.amazon.ca/Magnector-Perf..._1_2?s=wireless&ie=UTF8&qid=1421124799&sr=1-2
I've got genuine Sony and this one as well. Sony charger is cut more precisely, phone is held exactly as it should with no wiggle etc. But this alone doesn't justify 10 times higher price. The cheapo one does the job in the same way, I see no difference in charging speed. For example this cable is OK as well. If you don't mind waiting for delivery (it takes about 4 weeks to Europe), I can only recommend these products and Aliexpress site.
Regarding the cables with LED indicator - I've got one and even if it's interesting I don't find it useful. LED light is always on and when it reaches ~95% battery threshold it starts to flicker until fully charged, then the color changes to solid again.
Is it hard to screw up the direction of the charger? I've heard it will completely discharge the battery (It shorts the terminals?)
Also, is there a thin case that has a slot for the magnetic charging / what cases do you use if any?
Thanks for the info guys!
Theoretically the plastic around the terminals should prevent the connector from actually connecting "the wrong way" but in practice it can still happen, especially if you insist in moving and pushing the cable.
If the cable is coming out from "the middle" of the connector is easier to put it wrong (otherwise is easy to remember the cable has to go from the middle of the phone to the bottom so is much harder to make the mistake). However because the phone is so symetric you might confuse the front with the back and put it in reverse even in the docking station.
And last but not least make sure you have good warranty - it is possible that the magnet will "suck out" the connector from the phone, mine is barely hanging and is supposed to be from the batch that fixed this issue.
I have the original Sony dock as well as a third party dock. I also have a magnetic adapter for micro USB. All are working fine. Here are the links:
Third party dock - this works fine with my Z2 even though the title says Z3.
Micro USB adapter
Thanks for the reply unni_kmr, unfortunately I'm in Canada and I can't order through amazon.com easily. (Also that isn't on amazon.ca)
Anyone have input on whether I should get this dock for $15?
http://www.amazon.ca/PatecĀ®-Magneti...=UTF8&qid=1421438530&sr=1-15&keywords=z2+case
Also, I'm looking for a case that's slim but doesn't impede the magnetic charging port. Any suggestions?
EDIT: Found this case, might try to cut a charging hole myself

I don't have a case. I am using the Mocolo tempered glass on front and back. I bought it from here. Its very thin glass. Even with it on the front and back, the phone slides into the docks easily.
slow charging speed
hi there, i recently updated my Z2 , to 4.4.4 and everything is absolutely as expected but magnetic charging speed has taken a serious blow. with 4.4.2 it was as fast as normal cable charging but now with 4.4.4 it has become extremely slow , almost takes 8 minutes to charge 1%, and more than 8-9 hrs to fully charge ..
anyone else facing a similar issue .....kindly suggest solutions.:crying:
thanks

What do you mean by putting the charger in the wrong direction could be bad. Do you mean the magnetic charger can only work in one specific direction?

Not only it can work in only one direction but even worse if you manage to make it connect in reverse it might break the phone or the battery. Yay Sony!

I use a "magnetron" cable for several moths now and never had any issues with it.
It is not possible to connect it in the wrong orientation.
I'm really happy with it and would absolutely buy it again.

Very expensive cable though...
And if you wiggle it a bit I'm sure you can make contact with it even in reverse. I assume it is using like any other cable the normal "mechanical protection" which consists in a tiny (fraction of a mm) extra plastic on the "lower" pin from magnetic connector.

Issue with Magnetic Charging Cable

Hi All,
I recently purchased a Magnetic Charging cable for my Xperia ZU, but the moment I connect it through either Laptop or original sony charger, the phone re-boots. It does charge the phone, but at some particular orientation of magnetic side connection, phone resets.
Anyone else having same issue ? Any solution ?
Thanks

I've read it somewhere that charging the phone the upside down could brick the phone.. reset was the symptom. I have sony magnetic charger and it will not allow me to plug in the other side around. The most i get is the touch screen is not that sensitive after plugging the charger and it will refresh my current running app/game. Been using it ever since i got my device and so far no problem.

Thanks @wtfhax for your reply.
I think it was reverse connection which made phone reset. As I read in the links sent by you, magnetic charging cable is not a good solution then, since it can damage battery. I'll avoid charging with this cable now onwards and will stick with USB charging.
But, I think, this is a bad design from Sony. There should have been a protection in-built for reverse connection as well.
Coz the charging port are never meant for non genuine magnetic cable...
Just be careful if u still wanna use it by marking TOP on it...
Reverse polarity might cause the circuit to malfunction...
Cheer
hello
its supposed to do that m8 connect the magnetic chargers the wrong way round the the phone instantly resboots
to add..
Faced the same issue myself.
To add to this, ever since I have used the magnetic charging cable, my screen flickers - dims at times, phone doesnt respond and wat not. Thinking to reset factory or root it out.
Guys, would CYnaogenmod help?

Those problems occur during charging??
I have 1 magnetic charging cable that were bad and it tends to charge n no charge...
Better to use high quality or genuine 1 instead...
My magnetic charging cable pulled the whole port off the side of the phone.
My Sony battery case did the same.
I like the ultra but it is not built to last.

there is if you look at the contacts on your phone you'll see the contact on the right is more oval and the cheapo charger cables don't have the facility to detect the difference.
