Z3 Reboot when shaked - Xperia Z3 Q&A, Help & Troubleshooting

So, my Z3 has this very annoying problem of rebooting when shaked. When I shake the phone I can feel a part moving, quite a hefty one, it feels like a battery and it moves quite a bit. This is problematic since the phone tends to shake in my pocket which causes 'random' reboots and failed PIN attempts.
Is this common? How can I fix this?

Your guess is correct.
I did disassembly one to check the gps connections and my unit the battery is not glued or taped to the chassis... so it could happen that it shakes, after shaking the connector can move quite easily, the other thing could be a damaged ribbon connector.

Desire S casing 'vibrates' on touch - while connected with the power adapter

Hello,
I've noticed some strange behaviour of my Device.
It kinda 'vibrates' while touching the metal parts of the casing when connected to load the battery.
Like it's under current and a small amount of electricity is floating through the casing...
Not 100% of the time, but every time I replug the cable and while it's loading (=as long as it loads the battery I assume).
Does this happen to every aluminum HTC? Or Especially with the Desire S,
or is it just me?
If I misused technical terms I am sorry.
Happens on my device too. It also happens on my iPad2. I think its something to do with power, aluminium case and induction.
Hope this helps.

Weird fault with Note 10.1. Help!

Hi guys, newbie here, and im in desperate need of your help!
So I decided to buy an Note 10.1 and yesterday I received it. Straight away (after turning on) I noticed this rather irritating noise (like a notification sound but not one that is the ringtones options on the tablet) that the tablet made when I held it with one hand well, at first I thought it was a motion gesture since whenever I hold it with one hand (the right hand) it switches to the previous app if your in an app, or previous Web page when surfing the net. So I searched the options 100 times, and nothing to toggle off.
Anyway it bugged me more and more and I couldn't figure it out, then by chance i just pushed slightly on the back of the tablet and the notification noise goes off. Push again, it happens again. I decided that it could be a loose connection being made and remade every time I decompress the right side back panel (I can play it like a piano). So I took the back panel off (a pain in the ****) and noticed a ribbon cable that runs directly where I push the back panel (the S pen sensor cable). It was plugged in correctly, but wasn't taped to the battery like the 2 fatter ribbon cables.
So, I taped it down thinking that me pushing the back panel was moving it and creating a loose connection. I thought I had solved it. Booted it back up, no sound!!!!! Reinstalled the back panel, booted again and BOOM, the sound returns.......
Gutted.
Not sure what to do next, it definitely sounds as if something is disconnecting and reconnecting like a USB on a PC, im getting the sound but no notification or error. I have no idea why this would make an app switch to the previous app or webpage when on net.
Any help would be much appreciated.
Well, it seems I have solved the issue. Since this is a new account, I can't post youtube videos. So I'll leave those out for the time being.
Firstly, heres a video showing the fault. As you can see, I've narrowed it down to the docking station/charger connector.
The ribbon cable was seemingly depressed causing it to disconnect briefly before reconnecting when released. Probably the down side of having a flimsy plastic case.
Solve the issue I removed the ribbon cable and taped a small amount of foam right at the mouth of the connector, making the whole connection sturdier and harder to depress with the cover on, which can be seen here.
Hopefully this helps anyone who finds themselves with a similar issue.

that woulda went straight back to the store
Yep, if the problem isn't fixed there's no way it'll get fixed under warranty now...
If the device is less than a week old, in Oz, the shop is supposed to replace the device immediately. This doesn't mean they won't try the old "It'll take 2 weeks to fix" and "It has to be sent back for repairs" schtick....

Z3 in water and the phone thinks headphones have been plugged in

So when my Z3 is submersed in water, it acts like I just plugged in headphones. I'm guessing something is wrong here?
The feature works but sensing a short across the terminals, what would happen when you connect headphones. Water is conductive causing a short across the terminals causing the phone to think headphones are connected.
Two things you can do;
Turn off the application that runs when you connect the headphones.
Turn on touch block when you go to use the phone in water, then you can only use the normal camera buttons.
I have just purchased a phone protector that comes with a plug for the headphones jack, a feature I really like because my previous phone ended up with a fair bit of corrosion in there even though they were not used in water a lot.
Thats why you have the touch block option
Well, I got the phone replaced at a Tmo store this past Saturday. The replacement phone lasted two days, and it just fell about 1.5 inches and shattered the front screen (I placed the phone face down on top of a folded washcloth on the counter -- phone slid off the washcloth and landed on counter shattering).
Sure, this could have been avoided, but I have never had a phone shatter like this on me and this is quite disappointing. Not sure if I should exchange for a new Z3, or find something different. Gah..

[Q] Screen stops working intermittently, seems to be hardware related, help?

So I've been having a ton of issues with my phone lately, to the point I can't use it anymore. I'll list them in case they may show what the problem is. First, the charging port went out. I swapped out for a new flex cable on ebay and all was well again. Next the speaker stopped working unless I would squeeze the bottom of the phone, and then stopped working completely (Not sure if this was the speaker itself or if it was making poor contact with the new flex cable.).
Up next, and the worst problem of all, is the screen stopped working intermittently. I seemed to be able to get it working better when I would squeeze the phone, which seemed strange to me. This kept happening until it stopped working altogether!
So, thinking it was the flex cable, I just swapped it for another new one from a different seller, and it still isn't working. If I reboot the phone the screen works perfectly fine unless I put light pressure on the back of the above the "s" in nexus, then the screen shuts off and won't come back on again until I restart the phone again. As soon as I reboot the phone the screen works great again until I tap that spot.
I'm a bit at a loss to what I should be looking for, or what I need to replace? Is there some sort of short? Is a connection poorly made? It's a brand new flex cable and the old one seemed to be doing the same, and I've double checked the connections and they seem to be fine.
If you have any ideas, I'm all ears, just about to tear apart the phone to check where it might be making shorts around that area! Thanks everyone!
Seemed to be an issue with the flex cable connecter to the motherboard. When I added pressure to the connector the screen would work, as I let off pressure the screen quit. I ended up adding a few layers of electrical tape to the back of the connector so when I put the backplate housing and cover back on it would add some pressure. Seems to be working great now (knock on wood).

Thats a common experience you had. The connection between the USB cable and the motherboard for some reason can go bad. I suspect overheating may be the primary cause. The careful placement of double stick electrica tape appears to help fix this problem. I had to do it myself. The speaker not working can be caused by poor connection to the USB flex cable. There is an excellent youtube by "LE55ONS" on the disassembly/assembley which shows everything in great detail. It's worth a look.
Glad you got everything working

Oneplus One touchscreen not responding

Hello,
I recently replaced my oneplus one touchscreen myself with a replacement one I got from eBay. Now it stops responding when I turn my screen on and then after a about 20-30 seconds of hard swiping it starts responding and the touchscreen works as if everything is normal. Is this a known issue?
Well it would be more helpful if you give your current Android version, rooted or not and which firmware, might as well attach some screenshots here of about phone of your phone from settings
Hello,
My Android version is 5.1.1, not rooted . Here is a screenshot with rest of the details
Happened to me the second time I replaced my screen and sounds like the exact same issue. It was a grounding issue. When you took off the original parts, you should've noticed some chrome looking tape towards the top, under the motherboard. That was there to stop that main display flex wire from grounding out on the frame. I put a little piece of masking tape on the new assembly and it solved my issues. Hope this helps

Can you let me know where the chrome looking tape is? I am looking at this page http://forum.xda-developers.com/oneplus-one/general/repair-guide-oneplus-one-disassembly-t2979351 and I think the area you mentioned is showing under Step 16 and before Step 17?
Ok I followed the solution listed here http://forum.xda-developers.com/oneplus-one/general/fixing-ghost-touch-grounding-issue-hint-t2951000. So I put masking tape on the affected parts. The problem has definitely become less prevalent where the screen wouldn't respond for minutes to now sometimes the phone doesn't respond for about 10 - 20 seconds and then starts responding again. But once it does start working. It works continuously and it seems to me like something is trying to charge up and once charged up it works. So I don't think I have reached the final solution any other ideas? Should I just try heavier electrical tape instead of masking tape?
