If you have/get a USA TP2 you will be offered the split hard shell (leather wrapped plastic) case that actually fits and works very well but it has a MAJOR design flaw. Turns out there is a proximity sensor just above and to the right of the letters HTC on the front face (can't see it and don't know how it works) that is used for blanking the screen when in a call. The case TMo will try to sell you covers that sensor and it won't work. I took a 1/2" drill bit and made a hole just to the left and below the hole for the speaker (leaving enough plastic to keep continuity of the frame) and now the sensor works.
I will be calling my local dealer in the morning to make them aware of the problem. This needs to get out because the proximity sensor really works!!!! I wish I had it instead of the light sensor on my Touch HD.
Also make sure that ANY case you buy has that area uncovered.

A proximity sensors works by sensing if there is anything in its proximity.

I think I figured out what the OP is talking about. He's referring to a hard plastic shell accessory for the phone. The TP2 has a neat feature of turning off the screen during a call when you put it next to your ear. I wouldn't have noticed it if it weren't for the OP.

Comparing the TP2 to my HD I noticed, before I put the shell on, that screen blanks perfectly during a call when it gets about 1-2" from my face (my HD effectively does not have that feature) and functions much like, dare I say, like the iPhone for the screen blanking. It took me a while to realize the sensor is not near the LED/speaker area but about 1/16" (1-2mm) above and to the right of the letter C from HTC. I initially drilled a hole that was about 1/8" but it was too high and too far left for the sensor to work so I just made the hole larger and now it works perfectly....not pretty put it works. I actually like the hard shell (my wife, not so much since it makes the whole package bulky) and feel that it is providing good protection and good anti-slip properties.
My comment about not knowing how it works is based on the sensor is in a part of the case (phone case, not add-on protective shell case) that can not be seen, no holes, no windows, nothing. It is not infrared and is not visible at all. I guess it could be some kind of ultrasonic emitter/receiver to sense proximity, not sure. Anyone read about how that works?
Gordo
Pretty sure the sensor is optical like this:http://news.thomasnet.com/fullstory/562865. It can work through plastic that seems opaque to us.
On the EU version the sensor is to the left of the HTC logo about 1cm to the left of the 'H'.

Great info, thanks. I take it the EU devices have the letters HTC in a place other than just above the top left of the screen?
Question: I am looking on Ebay for another hard/split case like the one I got from my TMo USA dealer and see that some have a hole for the sensor but it appears to be to the right of the speaker. Do the EU devices have the sensor in a different spot?
This is the link I was looking at to buy but the hole is one the wrong side or is it just a picture that has been reversed? Or is that a hole for a front side camera that the USA devices don't have???
http://cgi.ebay.com/2x-MATTE-CASE-R...ries?hash=item4147ebe116&_trksid=p3286.c0.m14
My local TMo dealer said they would replace mine so i can drill the hole more accurately but I am still thinking I want to try one from Ebay.
Gordo
The hole in that one appears to be for the camera.
More screen blanking problems
Wow, after some research it looks like no shell/skin type of cases have the cutout for the in-call screen blanking proximity sensor.
If you have a shell/skin for the TP2, can you confirm that feature is/not working?
Gordo
I can confirm that the sensor does not work when I put my silicon case on. I ordered mine from ebay...there is a thread about silicon cases here. Anyway, I did a test like you did and sure enough, the sensor does not work when I have the case on. When I take the case off, the sensor turns off my screen.
Can you post a pic of where you drilled your hole? Thanks.
use a hole puncher on a piece of post-it... move that holey post-it over the suspected area... use other palm to simulate your face... move holey paper until screen blanks... and there's your sensor.
tmobile sells the body glove 2 piece snap on case (hard black case) as well as a 2 piece silicone case combo pack with a car chargeer. the silicone case with the car charger actually has an offset hole for the earpiece and proximity sensor unlike the body glove case.
moral of the story...get the tmobile combo pack that has the silicone case as well as the car charger.

Im thinking of getting this phone and so im looking for possible issues but I don't understand why this is a problem. If the phone is in the case, then it would be in proximity to something and it ensures the screen stays off so its not wasting power or getting hot right? Then when its taken out of the case and you bring it out of suspend mode the screen and all turns back on....? what am I missing here?

Hey Gordo,
I am curious. If the prox sensor blanks the screen when it is close to your face, wouldn't you want it to also blank the screen while in the case? That would seem to keep alerts from leaving a live screen and wearing down the batteries. (That happens to me now with my Tilt.) If so, then you do not want a hole in the case?

If you look at my original post I mention that this problem is with the split shell case that is being sold by factory Tmobile retail stores in the USA. Ebay also has a number of 2 piece cases/skins/shells that, without a hole for the sensor, will frustrate people who might not know that the "screen blanking while in call" feature will be rendered unusable. Someone mentioned that it is the Body Glove, hard plastic wrapped in leather, 2 piece case that has one part clip on the display part of the phone and the other part on the back of the keyboard half of the phone. Both halves of the case are intended to remain on the phone. If you are just placing a naked TP2 in, say, a pouch case, then this is not a concern to you and should blank the screen if you are in a call while using a BT headset.

Can you please post a few pictures of the Body Glove case (thanks for replying to my previous thread). I cannot locate any decent pictures of the phone from various angles with the Body Glove case.
Thank you

I've had my Motorola Defy for ~3,5 months now and I'm happy with it exept some quality issues.
The battery seems to fit very bad and is wobbling when moving the phone quickly.
The volume buttons are also making sounds seems to be bad fitted as well.
It doesn't exactly scream quality over my unit, and my question is:
Is my Defy defect, and should be replaced? Or is this something they can get away with?
Enjoy my video.
http://www.youtube.com/watch?v=DI7rEVuNbs4
No it's not defective. They all do that. I put a little piece of foam under the one corner of the battery to stop the wiggle. The volume rocker is just a plastic piece between the case and the actual buttons that are underneath. The real buttons are sealed for water resistance, so the plastic button that you press will wiggle a bit because it's not really attached to anything, but rather it floats there.
My battery wobbles about, fixxed it by jamming a slightly folded piece of paper between the chassis of the phone and the battery at the top near the camera.
My volume keys are also wobbly so to speak, but I havent found a fix.
Im not bothered about getting exchanged either, its too much hassle.
My battery doesn't wobble. My volume keys don't rattle. Today is 7/11 you should be lucky otherwise.
yeah, my battery wobbles too, and i too put a piece of paper between the battery and the case never had any problems with the volume rocker though...
sent from my cm7 defy
Thanks for your replies guys. It seems like this behaviour is standard on the Defy. Which is a shame. The quality feeling over it is completely blown away and makes me really sad to know what an excellent phone it could've been (Without having to McGuywer things).
Well, will have to think about returning it or not. I really want to have a non-wobbling phone when I've paid several hundred dollars for it.
Thanks again.
A little wobbling is okay, and sometimes desirable, you have to take into account the thermal expansion characteristics of different materials.
If everything fits "too well", it's more easy to break under extreme temperature.
Designing a key that has little to no wobble is very difficult if you consider that there are variations in every part that make up the design. There's the variation of the tactile switch under the key, variation in the placement of the switch itself on the circuit board, variation in the injection molded plastic housing, variation in the injection molded plastic key that you interact with on the housing.
If you were to design without considering all the possible combinations of the parts with different variations, you can end up with 2 scenarios
1. The keys are so tight that they actuate the tact switch permanently without you having to press on them.
2. The keys are so loose that even when you press down hard, they don't come in contact with the tact switches on the circuit board, and you don't have any function.
Functionality is always top priority. Wobbly keys are the side-effects of manufacturing variations, and we'll just have to live with them. Out of 1000 products, you may get 1 where every part seems to fall into the right combination, and you get the perfect fit. If so, you're damn lucky. On the other hand, you may also get 1 where every part seems to fall into the wrong combination to make a super wobbly key, but the design would have taken into account that it would remain functional. If so, you're unlucky, but it's not considered a defect because it still functions when you press it.
Is there any way to clean the dust in the camera lens?I think it affects my camera quality so it does not take quality picrures.Please help thanks!

I had not dust, but some kind of a residue that was making the lens cover "foggy" from the inside. I discovered it when I removed the back cover from my phone (for different reason). Cleaned it with a q-tip, which made pictures much better. So, if you are sure you have some crap inside, the only way to get rid of it is to remove the back cover, and clean it up. It's not a difficult task... You need to remove two screws at the bottom, and carefully pry your cover open, starting at the bottom, and working your way along the sides to the top. Don't forget to take out your SIM tray BEFORE removing the cover! When you're done, put the cover back, starting at the top, and snapping it in place along the sides, and down to the bottom. It's a bit tricky to hold side buttons in place while snapping the cover back on, but not too much...
The images from my front facing camera have gotten more and more washed out over the past few months. Apparently there is a small bulge in the aluminum right below the camera (where is connects to the black glass). The bulge is so slight that i can't even slip a piece of paper into it, but apparently it is enough to allow the occasional piece of dust in, so now the lens is coated with some debris (washing out the pictures).
I've tried canned air to no avail. I'm wondering if it makes sense to try and pry the bulge bigger to provide a better opportunity to clean the lens. I definitely don't want to take the whole screen off just for the front camera lens, but if there were a less involved disassembly to get the upper grill off or something, I'd be willing to try that.
Anyone have any suggestions?

Try to contact either HTC for a free repair (telling them your front camera is not working) or try to do the same thing with Verizon for them to get you a Like-New replacement (it is very easy to get them to do that, they ship one out for almost any problem). You are for sure within the 1 year standard warranty that comes with every phone since this phone only came out on August 28, 2013.
Can anyone with a smart cover (the ones with magnet) confirm the location of the embedded magnet on the cover?
I believe book or simple covers, all allow the magnetic lock/unlock of screens.
Need it to emulate the lock/unlock feature using an old non-magnetic cover and some spare magnets I have.
Device : Samsung Galaxy Tab S Wifi 8.4"
I took a small piece of magnetic tape, which has a low magnetic field, and located a spot on the rear, along the right side, near the bottom. Touching the back about 1/2 inch in from the right side and about 1/2 inch from the bottom on the back with the tablet facing you is where it would turn off/on.
If the screen is already off, the magnet will turn it on and it will stay on when the magnet is removed.
If the screen is on, the magnet will turn it off, but when removed it will turn back on.

I found the exact spot! (the red spot at the bottom in the pic)
Works both from front and backside.

Yeah...but if it's a real weak magnet, hardly any pull, it won't work from the front. Which makes me think the switch is closer to the back. Dunno what the OP is doing but it might make a difference in how strong a magnet he uses.
But it's close to where we both have indicated.
Hello, anyone knows the location of the magnetic sensor in TAB A 2016 SM-T580 please??
