[Q] How to replace vibration motor

My vibration motor in the Nexus s broke. Now I want to replace it. I'm planning to order this motor: http://www.tvc-mall.com/details/Replacement-Vib-Vibration-Motor-for-All-Samsung-Models-SAMO-SAM/
I opened up my Nexus to a degree where I could see the motor, but I couldn't see how the wires are connected. Do I have to braze the wires or can I just plug them in or how does it work?
Thanks!

Are you positive it is broken? Mine stopped working on me a few times before. I would tap the phone firmly, powered it off and tap again and reboot. Problem solved. Just a fyi

Yes I'm sure it is broken.
Thanks tylerwatt12, for that picture.
Crap I don't have the equipment to solder.

A 15W soldering iron should run you around $10 US.
I highly recommend soldering wires on random scrap if this is your first experience at soldering or you're gonna end up with a mess.
Edit: Or you can cut the wires, strip the ends, twist them together and solder (then cover them with heatshrink/electrical tape).
Should be easier for a beginner to do this than solder on tiny pads and remove epoxy from a PCB.

Thanks, pretty stupid, I didn't think of that. I might not even have to solder at all if i twist them together tightly and then bind them with tape.

riichii, have you managed to do it? I'm positive my vibration motor is broken as well, but I cannot find an exact replacement online. A friend of mine had a broken samsung j700 lying around so I salvaged the motor from it and soldered it in my nexus s, but it didn't work (you could hear the motor rattling, but it wasn't vibrating enough, it was less than my broken original motor). I was wondering if the part you linked was working or not. Thanks

[SOLVED] GPS Fixed!!! For real this time.

It's a noise issue with the gps antenna and other h/w on the board (mainly lcd cable.) It can be fixed by insulating the board from electrical shorts (scotch tape in my case) and shielding the board from the antenna with aluminum foil. Not for the faint of heart, obviously you can ruin your phone if not done correctly. If your wondering how much of a difference it'll make lets say my GPS works in my basement, in walmart, even in a multistory business office. I have yet to find a spot where it won't work. Most times it locks the instant it's opened, indoors you might have to wait maybe 10-30 secs.
If you think shielding the whole phone will help the other antennas, it won't I tried. You only have to do the corner that the GPS antenna is located and of course ground it. The GPS antenna is labeled with the letter G on the case of the phone. It's inbetween the camera, battery, and power button. Face down camera up, it's located upper left portion of the phone. Each antenna looks like a black label, please don't peal them off. Phone must be disassembled to perform this mod. I will not tell you how to take it apart (google it) nor be responsible if you break it. If you don't understand the concept of shielding or are unclear how to do this mod you shouldn't be doing it. You should be asking a friend that understands electronics better (aka major electronics geek) to do this for you.
Sorry I don't have pictures at this time.

Only the area where the GPS antenna resides needs to be shielded which on the Nexus S 4G happens to be circled in red.
Don't forget to protect the board from electrical shorts with scotch tape or the like.
Please don't put tape or aluminum foil over the spring terminals as they provide contact to the antennas on the back of the case.
The shield must be grounded for it to work, I used the metal casing inside the phone.
You can see where it comes close to the edge of the phone, it happens to be metal there and its grounded

In for pics. Also, which model phone.

crespo4g aka SPH-D720 aka Nexus S 4G
But TBH this solution should work on any phone that has bad GPS reception due to bad design and/or h/w interference.

Sounds similar to the other fix which didn't work for me. Do you have pics of your mod?

Yea I just put one up. I've tried many things myself but this has made my phone's GPS f***in fantastic and thought I'd share it with the rest of the world to enjoy. I first tried modifying my antenna with a wire after trying a bunch of useless s/w mods but still wouldn't work once reassembled and then it became obvious what must be done.

Dude, that fix looks so hood rich. I love it.

Waterproof GPS case for Nexus 4

I wonder if the N4 would fit in this waterproof handlebar-mount case.

It looks like a definite maybe. The width would surely be too much but the height might be a bit too tight. I have a 90-degree micro-USB cable on the way but that still ads another 1/4" of height to the phone too. A little bit of foam padding would need to be custom-cut to keep it in there if it did fit and keep it pushed up to the top of the case.
I've also got one of those external USB battery packs that might even fit behind the phone and act to shim it out but it might be a tad too thick. I wish I knew exactly what the internal dimensions of this case were.
I wouldn't use the handlebar mount clamp but would instead vecro it directly to my handlebar bag on my bicycle (It's got velcro built in to do just this with a map case that came with it.) I would probably do the same exact thing with my motorcycle tank bag and be able to use it for either depending on what I was riding.

Did you try it? I've got a nexus 4 on the way and would love having gps on my motorcycle. I've looked for this sort of thing for my thunderbolt but didn't find a great fit.

It does fit as I have one for my mountain bike.
I also put a battery pack behind the phone with a right angle USB connector and use it like that.
The phone can also be used through the case without having to take it out all the time.

Tilt Vu overheating

I started using Tylt Vu with Note 3 fitted with aftermarket Qi receiver. Vertical charging overheated the phone but it was fine when placed horizontally. Fast forward to now : Note 4 with Samsung original wireless charger back cover. Same phenomenon. With horizontal placement, it is almost not warm at all. Vertically it is super hot to the point I feel not safe for the battery.
My initial theory was that two coils must have got active and more heat generated. So decided to detach additional coils. I opened up and inside looks as you can see in the image below. For the sake of clarity, let coils be 1, 2 and 3 from top to bottom. When Note 4 is placed vertically, center of phone doesn't align with coil 2 but like 1 cm above it. So my theory of two coils getting activated looked correct. I detached coil 1. With phone vertical, it is clearly out of reach for coil 3 to get activated. Hence coil 2 for vertical and coil 3 for horizontal placements. BUT overheating didn't go away.
My next theory : As you can see coil 2 sitting above coil 1 and 3, it touches charger base and heat gets easily transferred to the pad. Or maybe it is closer to the phone, more electricity gets inducted by coil 2 and hence more heat. And to back this theory, when phone is vertical not only the phone but charging pad gets hot too.
Will be sticking with horizontal charging until better charger comes by.

When you are in vertical mode, do you check that your receiver in centered with one of the couls? Maybe when in horizontal the receiver and one of the coils are perfectly aligned?

I remember checking picture posted by someone who had peeled off original back. I have been searching for that so I know where exactly coil is located in the charging cover. I am searching for phones among friends who have aftermarket Qi coil so I can test and confirm center coil of Tylt Vu is the culprit.

Are there any QI pads that are both thin and with a small footprint?

I need a QI charging plate for my Honda Super Blackbird, where I have the Ram Mount X-Grip cell phone holder:

I want a charging plate that's no wider than my S5, and at the same time isn't higher than max 5 mm, preferably smaller. Are there any plates that can cover both those criteria? It's a pain in the ass when I have to mess with the charging cable, especially on longer multi-day trips, where I often take breaks and leave the bike, and I use the phone as a GPS with the screen on all the time.

this one might work for you! the width of this qi plate in the widest part is couple mm wider than my S5 (in superslim case) and height is about the same as S5 as well. the question is how you gonna avoid using cables with qi plate?

I'm afraid it's far to tall. Like I write I need something only a few millimeters thick, preferably less than 5, or maybe I understood that wrongly? The phone is around 8 mm tall, and a pad that high would put it dangerously close to the tip of the rubber on the holder. In 20 kmh on the Autobahn there's not much chance the phone would survive falling off (not to mention that I would never find it). And wires that I have to something mounted on the bike is no problem, I just don't want to plug in and out the charging cable of the phone all the time (espescially with the stupid lid over the port, and the annoying "remember to close the charger lid" messages I have to click away every time.
