has my vibrator gone bad?

my phone won't vibrate when it turns on or when receiving texts or calls. even if i switch it to vibrate it won't. if i shake the phone a bit before i make a panel selection i get a click from inside the phone when i select the panel. it's like it wants to work but it won't work all the way. anyone else had this problem? if so how do i fix it? this is frustrating. thanks for any help
EDIT: (just so you don't have to search through the whole thread)
Found out that the problem was HTorch. I used it for only a few minutes on high power and it melted the Led on top of the vibrator motor and locked it down. Heed these words, comrades. Take special care not to use htorch on its bright setting. cheers

if hardreset dont do anything then
i would say that it's a hardware malfuntion
which require service

I thought this title was referring to something else

me too!
There's a thread where someone else had the same problem, more than likely the motor has burnt itself out or the weight/cam has dropped off the end of the shaft (LOL). More than likely a return to SE/your provider to get it fixed.

God you just jinxxed mine! Vibration is dead now. Nothing on calls texts or anything. Even when I go into sound panel to test it doesn't work.

Just done a hard reset and nothing.
Looks like a service job already....

I had the same problem and in the end had to get a replacement.

I sent my X1 to service last week because of the same problem.

christ... that sucks you guys! i'm gonna attempt to open mine up and see if what squidgyb said about the cam falling off the motor might be the case. report back later

what i found is not pretty....

that piece that looks crooked with a yellowish square piece on it shouldn't be crooked. it should only be occupying that blue rectangular space. it seems to have overheated and melted itself out of place. if you look here:
http://www.youtube.com/watch?v=AWDurQrRt-Y&feature=related
at 2:26 you see what it should look like on the right side of the camera. it's new resting place is (guess where ) snug on top of the cam and motor. it's locked down. i would just like to know what it is and why or how it overheated. it seems like a simple fix... if i knew where to buy that black plastic thingy that is now melted. i just figured this was some interesting info to share. i really can't go without my phone for however long it would take for them to repair and ship it back to me so if any of you know of a place online that i can buy xperia parts, feel free to post a link. thanks you guys

that's the one...

Good job in finding out what it was. However, I didn't pay good money to fix it myself so it's going back to O2

O2 have no stock and are giving me the 'sometime next week' crap again. Then he said go into a shop and see if they can fix it as it may be software.
Looks like I will re-flash the ROM back to normal and then bring it into a store. Then it's either send off for repair or wait for stock. My Jedi senses are telling me that I am going to kick off very soon....

i thought about what i asked earlier about someone posting a link to buy replacement parts and then i remembered that parts shortage they went through that delayed everything. if sony/htc can't even get the parts they need to make the phones, then how am i supposed to get the extra parts that i need to fix mine lol so despite my impatience, i guess i'll have to send it back

Vodafone or O2 figurine?

best thing really, you don't expect to pay all that amount of money for a phone that is 99% working. This is my first SonyEricsson that I have sent back within 3 weeks for a hardware fault.

mine is an x1i unlocked from the uk and i'm a kid in the u.s. on t-mobile lol. wish i did live there though. that'd sure be swell

really though, these ARE the first on the market so ppl shouldn't expect them to be without their flaws just as with any other high-end item be it phones or game systems. time must be allowed for all the creases to be ironed out.

Good luck figurine lol
And yes I do expect problems and I am not that mad with SE but O2 should be able to support their customers in a reasonable timeframe as we paid good money for them....

that wasn't aimed at you guru... it's these ppl that make a big deal about having to send their phone back within a few weeks of getting it due to hardware or software issues. It's to be expected. they should wait a few months until the bugs are worked out or something

eken m003 8" tablet tear down and hopefully upgrade

Hi,
I trade out for an Eken M003 8" tablet running 1.6 on it. I can not stand it as of right now. I decided to do a tear down of it to see if it was indeed able to be upgraded. I have search all of the world wide web for anything on this, and so far I have found barely anything. I will be adding Pictures tomorrow.
Does anyone have any thoughts on this device, other than it is cheap? It has a wm8505 Chipset in it and a small ram chip as well. I am not advanced in the Hardware side of things, but I do like tearing apart..lol. I tried Wondermedia, and Via to try and buy another chipset for it, but I cant find one. Hell even if I can desolder the ram, I cant find anything to get back on it. One question I have is does the WM8505 chip actually contain the O.S. on it? If so what would happen if I did indeed replace it with a blank chip? Could I put an operating system of my choosing on it then? What if I increase ram from 128-1g? Lots of questions, and the only site I can find is Slatedroid, but it is non operational. I have a rooted Nexus and it is faster that this POS. I dont care what really happens to it, I just want to experiment. Any suggestions?

wm8505 chipset found inside EKEN

I just found tw6805 on everbuying.com,but i don't know whether it agree with yours.

The problem with these things is that, they are so cheap.... you cannot expect support. I really don't see the purpose of an Android tablet if you have an Android phone or a PC/Tablet PC

I agree about cheap, I didnt pay anything for it, I traded out something I didnt want for it. Really just wanting to try and upgrade it and see just how fast it is. I have a Nexus One that I love, and it is faster than this thing by far. Would be cool to stick in 1g memory, and 1ghz processor. Then I just have to learn how to port custom rom on it, and instant Bathroom fantastica!

take it apart
Hi tytngasman, how you dismantled it?
Do you have any suggestion?
I need to open it to check why the display looks garbaged.
Thanks.

There are 2 crews at the bottom, and an additional 2 screws under the bezel on the left and right side. Then just pop the tabs, and there you go!

Great! Thank you.
My M003 has got a very strange issue: if you push back the sim-like cpu card the display stop garbaging. If you leave it alone, all images are scrambled!
I was trying to glue the sim but is a no go...
In the meantime I broke the touch screen
Then... game over.

I dont understand what you are talking about with the glue. What sim-like cpu chip? The only removable thing on the board is the wm8505 chipset. It looks like a piece of Laptop Memory. Should have two silver clips on the board that it snaps into, and should be about 3 inches by 1.5 inches. do you have a pic of the part? also you can get another screen.

yes, the sodimm like card with the chipset.
if I push it, the screen is clean, if I leave it alone the screen is garbaged
I suppose that the problem must be related to wm chip itself (bad balls) or to the sodimm connector.
any suggestion?
ah! I just bought off ebay a touchscreen replacement for 15$ shipped.

i HOPE THAT WORKS FOR YOU, iF NOT SEND ME A PIC OF IT. Soldering is really easy though. If that is the problem, Also could be in the clips on the side. If you pulled out the chipset without first unclipping it, then it will not hold correctly.

[fix] An easy way to solve the screen flicker with just a scotch tape

Hey guys,I'm a nexus 7 user from China.
I have solved the screen flicker problem.
Just put a piece of scotch tape on the GND point of WIFI antenna.It does not influence the signal strength.

Not gonna do that. By not connecting a ground you could run into some other serious problems later on. Excessive WiFi chip heat and possibly other issues

Won't be.I have studied the wifi antenna for several years.Wifi antenna has many types,some of them like omnidirectional antenna,it‘s RF line and GND is not connected.

I've just done this. So far, wifi strength fine and there is definitely less flicker.
However, this its light outside and it's much easier to see the flicker when it's dark, so I'll let you know.
Thanks for the idea, and hopefully this works!

I'd definitely this if I was more confident in opening my device

Watching with interest, before I go through and attempt it.
may i ask what is your theory why this works? In simple terms! If I could sort the flickering I'd be v happy. Thanks
Sent from my Nexus 7

Confirmed as working on my device. It completely eradicated the flicker too, which is awesome.
I also would love an explanation as to why it works!
Sent from my Nexus 7 using XDA Premium HD app

I cant really tell by the pic, is that just a piece of clear scotch tape taped over that metal part? Its not in between or anyway special right?

Does anyone have any information on why this works and if there is any possibility of it messing up the tablet?

Just slide your finger or thumb nail between the top edge and the back on one corner then slide it to the other top corner and the back will start popping right off, it's very simple.

Oops. One off on the copy and paste:
http://forum.xda-developers.com/showpost.php?p=29759410&postcount=295

So this makes me wonder if the common issues could perhaps be with the back of the device. I've seen people with screen warping issues caused by a warped back, and now there's a fix for flickering by modifying the back.
I'm sort of curious to see what switching the back of a flawless device with a device with flickering does.
Edit: I also remember someone saying awhile back that they pushed on a certain part of their device to make the flickering disappear, which makes me even more curious if it's something to do with the back..
Another edit: The device would not flicker when the back was completely removed. Obviously, without the antenna, the signal was very weak, but the flickering would disappear. As soon as I placed the back on again, the flickering returned.

Only engineering theory is the antenna is moving the voltage for ground w/ the power surges when it uses full wifi power and this is affecting the ground level for the rest of the tablet including the backlight. By putting the tape there, you're preventing the wifi antenna from affecting ground level, though I don't understand why it doesn't affect wifi power (I'd think that by doing this, you're lowering the transmitting power of the wifi antenna).
Any other EE's confirm this might be what's happening?
Interesting workaround at least...it's basically a hardware version of the software workaround I theorized was possible if they could control the power transmission level of the wifi chip/antenna...

This fix makes the difference, its like night and day... thanks to the op

I decided to go ahead and get a replacement... Call time 3:14 no joke. Super impressed with the service and the process.

Not sure what you're talking about in "disconnecting ground," but the ground plane is pretty important for PFA antenna design. (I'm assuming that's what the N7 has, as there still isn't a good photo of the ants themselves in any of the teardowns.)
BTW, funny, but I made that very same antenna in your pic, along with the PVC pipe cover. Didn't work too well as an omni. I soon ditched the DIY route when I found surplus WISP ants to be much more effective, and less hassle.
BTW, a good read for wifi design is "Antenna Design for Mobile Devices (Wiley 2011)."

I'm going ahead and doing the same. It does look like modifying the back cover will fix the flickering issues, but after reading a bit on how the ground effects antenna performance, I'm a bit wary about it in the long term. It'd be one thing to just tighten a screw, but to disconnect a wire with a function isn't okay to me.

I've pasted some pages out of the abovementioned wifi design text on the effects of ground plane on mobile antennas. It's probably too technical for many, but you can get the gist, which is that the ground plane is a "big deal" in antenna performance.

Remove the NFC card

Hi All
Sorry if this is in the wrong place but I guessed you were the guys to help me... Want to remove the Near Field card from my Nexus 5 and my question is...
Will the phone boot up, and work, without it
May be daft but don't use it, don't like the idea and would rather plug a speaker into the headphone jack rather than use anything wireless...

Why would you want to ever remove the near field card it is pointless and you can damage the system if you don't know what your doing if your worried about loosing personal information just keep nfc off and android beam

Hi..
Wondered if I might get this kind of answer....
The question was an honest, if bizarre one, as looking at the strip down info on here it showed the near field card as a plug in...
I did just genuinely want to know if the phone still worked/booted without it as someone may have... lets say... not plugged it back in properly after a rebuild... or even had a try to see what happens....
As the 5 is my only phone I just wanted to ask rather than do...

I once tinkering my nexus 5 and the vibrator didn't placed properly. The phone still boots up but no vibration. I thought it's safe to remove the nfc but i strongly suggest that you shouldn't do that. Just keep it turned off

Or else the most easy but forgotten solution, is to stick a little piece of insulating tape,but any other would be ok, over the NFC contacts . Phone will boot no problem, but even if I m ok with this strange question, I can't understand how NFC is related to headphones... Maybe you want to hardware disable Bluetooth? The easy solution this time is...
The same,just stick a piece of tape over the Bluetooth antenna contacts,but in this case I can't tell you if it will or will not damage the Bluetooth controller if you leave it activated in android.

Man, that is beyond far fetched. A bit paranoid to say the least... Should probably remove your wifi, bluetooth, and cellular modules and antennas as well, rip out your wireless charging receiver, throw away any wireless chargers you own, and throw away your home router, and move to an area with zero cellular reception.

Thank you. I've already watched that video in the past, but it doesn't say what these are.
They also look like plastic instead of metal, so I'm still unsure if I'm missing something or not...

My speculations are that those are the connection for wifi antennas. Last year, I was changing the LCD, ive made some research that on some cheap LCDs they dont have that connector, and that people are complaining their Wifi becoming non-existent after using that screen. I brought the OEM one that costs abit more, about 27 USD in aliexpress and i notice no wifi issues what so ever (apart from the distance being ****, true to its original condition lmao). Another guess is that its for the touchscreen grounding i guess??

That would make some sense... my wifi performance on 2.4GHz is just miserable, it struggles to find the SSID even if I'm standing next to the router.
Interestingly enough, the same router puts out a 5GHz SSID and that one is mostly fine.
Now, if these connectors have something to do with wifi I still can't seem to find the parts online. Only the coaxial cable shows up, and I thought that was the only antenna connector for wifi...

I think you need to refer back on the original part of the screen. From my knowledge, these are a part of the frame of the screen assembly, so you can always transfer the OEM/Original old parts to your new screen. Or maybe next time make sure to buy the oem version that has complete features like what i did. I hope it helps!
