What is this black pad on the frame??? - G4 Q&A, Help & Troubleshooting

What is this black pad? it doesn't touch the cpu which is notorious for overheating.
Its like a cushion and its feels like rubber.
I wanted to apply some thermal paste, but that black rubber pad is there.

Maybe a thermal pad?
My advice: search a little more about that (use of thermal paste), and only if you find solid proof that it works, than do it.
Compare the number on this video: https://www.youtube.com/watch?v=QijWruGXqX8 (turn on subtitles) and see if there is a considerable or any difference.
Your phone...

Put thermal paste on mine last week and its been running mutch cooler and i dont burn my hand after using it.
idle 32c(from 38) and maxed out 70c(from 80+) after 20min game test, but dropped instantly when closing. Didnt bother thinking about that pad as the paste isnt conductive..
Make sure you put paste directly on the cpu's as well as there isnt any.(under the thin metal cover on motherboard, carefully lift it up with a knife or thin object)
then apply a few dots on the metal around the black pad.

I open mine to take a better look and to be honest it looks just like paint. No softer/harder material than the rest, didn't saw any corner or edge that I could use to take out...

How weird, mine is definitely rubbery with 2 holes that hold it down. I could lift the corners. But I didn't, I didn't know if there was anything back there to do with the Lcd. So I thought I would ask here first before I go messing with something that I'm unfamiliar with.
Look at the picture below, there's an indentation for the cpu, clearly its there to not touch the cpu. The cpu sits low, slightly beneath the metal shield and is covered by some type of fabric heat tape.
I'm guess the black pad is there to block the heat from reach the lcd?

I went all crazy and spread the heat out. With thermal pads & paste on both sides.

oil slick screen

had my TP2 nearly a year but recently i have noticed the screen has like a rectangle shape oil slick type mark on itvery noticable and seems to be getting worse anyone else had this??
its as though there's water under the screen protector but when i remove the SC its still there
search newton ring.
newtons ring??? kind of the case. the "oil slick" is mearly trapped condensation between the digitizer and the top plastic covering that you catually touch(the plastic you put the screen protector on). moisture seeps in through the bottom keys and earpiece in forms of vapor and liquid. this occurs when you have your phone in your pocket or use it in humidity(shower or weather)...congrats, you ve trapped your sweat lol. the reason why its rectangle is because the screen/digitizer and top plastic are not set flush together. as you know, the top plastic is very flexable so you can take your finger and feel the various componets in the empty spaces. i can confirm my finding because a few months back, i replaced my tp2 screen. i seen it had the oil slick before i opened it and before i put humpty back together again, i wiped under the plastic screen and felt a slight moist film. i tried to guess how the hell water got in and i concluded by a salty electronic taste...yeah i smelt and tasted it...that it was sweat. i always carried my phone in my front pocket and over time, the sweat built up. after a wipe with electronic cleaning cloths, an air dry and then an air can blow(i love my phone lol), i put it back together and bam...no oil slick. another way to think of my theory is, you know when you swim with your watch and condensation builds up on the inner quartz and makes it look foggy?...same thing here. only thing different is that there is only one flat surface and not 2 like inside the phone so the moisture wont look like an oil spill, it will just be foggy.
so how do i open the screen up to get rid is it easy enough to do or will bloww warm air over it do it ???

there are lots of vids on how to disassemble the tp2. check youtube. just to let you know, its a long process. you have to take apart the entire phone just to get to the screen...good luck.
ps i would post the vid link but im typing this off my tp2. if you cant find a good video, i will link one here later.

What's the deal with the blue tab

My last two refurbed DROIDs and my DROID2 have had the blue application tab for the screen glider sticker left on. Why is this? Ive just been getting a sharp knife and cutting them off. Is moto just getting lazy with all their device success?

The blue tab is to allow you to easily pull off the plastic sticker on the back of the screen; they put the plastic there for shipping and packing. Since you cut off the blue tab, it is harder to pull it off; though, the plastic sticker won't hurt the phone, so no big deal either way.
i left it on to keep the slide tight
My initial DROID 1s all had that sticker. Not sure how much it makes the slider tighter by, but it certainly does it's job eliminating metal on metal friction. Like a lubricating / pressure sticker. I don't think its supposed to be removed at all.

it IS supposed to be removed and it's not providing the "lube" effect that you're noticing. check back to a few sites that have actually dismantled a DROID. the sliding mechanism is where the two slots are on the back of the screen.
there are only two objects sliding against the plastic:
the locking mechanism
and the data ribbon
the backing is meant to be removed and provides no protection or benefit.
I'd like to see some form of proof because I can easily argue this.
There are very clearly on both the droid2 and droid1 two pair of wear marks right across this sticker. Plus the last refurb droid I got has the sticker with no blue tab.

i've replaced my backing with a vinyl sticker. the two wear marks are the spring locks that keep your keyboard closed. nothing else. the D2 is constructed identical to the D1 in that regard.
FWIW,
Every single time I have removed the sticker on the back, I ran into two things. Number one, it leaves it sticky. Number two, it makes it near impossible to open the phone quickly. Maybe cleaning it etc.. would fix that problem, but i'd rather just leave it alone.
I've seen a few phones with blue tab stickers, some with two pieces of black tape covering the area.

My girlfriend has an R2D2 Droid2, her's was the only one of the 4 Droid2's I've personally seen with anything left on it, and even so just 1 aclohol wipe out of a box I got at a drug store cleaned it off

Yeah that thing isn't supposed to be there.
My Droid and Droid 2 were just as tight after taking it off... and 6 months later (well just got the Droid 2 so just the Droid on that part )
I actually think they are supposed to be there. I have two pieces of tape and this is my fourth droid 2. The first one without the tape actually had the sliding mechanism leave marks on the backing of the phone where it slides up and down and is hideous. The tape reduces the contact with the back and" absorbs " some of the blow. Im glad I got the two pieces of tape instead of the blue lining because its more pleasing to the eye.
Also it seems more snug and smoother with the tape.

Have any of you EVER purchased ANYTHING electronic? The pieces of plastic with the blue tabs are just there for protection from scratches by anyone OTHER than the customer. The blue tab is there so you can pull that TEMPORARY plastic piece off.
Its the same as that plastic thats on the main screen (you know the one that you probably pulled off?) that tells you what each of the little buttons do.
This is the most pointless topic ever, Lol.
Just compared to my old droid 2. The droid 2 has scratches where the sliding mechanism is and my new droid 2 which I have had for a couple months does not have any scratches as I have left the blue tape still there.
LOL...the blue tab is there so you can pull the plastic off. seriously?..is this topic really real?

if you guys think that the tape is really making that big of a difference, buy a vinyl from here:
http://www.grfxpstore.com/store/search/results?search_query=droid
that tape is made to come off, why do you think it bubbles up? it's not meant to be permanent and it's NOT the sliding mechanism leaving marks, it's the LOCKING mechanism. there are two little tabs that rest in slots at the top of the screen when the keyboard is closed, to help keep the screen from opening (although it does a piss-poor job). you can clearly see the path (scratches) from those tabs leading right to the slots at the top.
there are x-rays and tear-downs of the DROID 1 (same design/functionality as the 2). the sliding mechanism is located in the slots on the edge of teh screen.

[Q] How do I fix gauge/scratch on frame of phone.

The outer frame of my phone (the metallic plastic border-frame-thing) has a scratches and gauge on it now because I dropped it few weeks ago. I know it's just the appearance but at times I just find myself staring at it with discontent.
Here is the Link to the photo of it. (remove the spaces I'm a new user)
http : / / yfrog . com / n415092010127j
So I ask what would you do if you vibrant has that gauge/scratch?
Do you think it's fixable? maybe just sand it down to smooth it out or would it be make it worse?
Is it possible to get a replacement part?? I cannot find anything online but... I did see the non-working "T-MOBILE DUMMY SAMSUNG VIBRANT T959 DISPLAY PHONE" model on ebay.. do you think I can take the part from there? (haha, I think I do sound somewhat desperate)
oh and is there a case that just covers the perimeter of the phone leaving the back and front exposed? (I have a case for my phone already it but it makes the phone look pretty bulky)
Thank you everybody
I'd like to know this as well as I dropped mine on Friday and scratched all four corners! I thought about sanding it to give it a brushed look, but since it's plastic, I have a feeling it would look like crap.
Can you replace just that part?
Just put it in a case that covers the chrome bezel.
I had a similar issue when I had my blackberry 8900. The "chrome" around the sides started coming off, so I picked at it with my nail until it all came off. It was smooth black plastic underneath, and I'm willing to bet that's the case with the Vibrant.
You could tape off the parts you don't want scratched (screen, buttons, etc.) and use sandpaper on the chrome.

Just use a good quality liquid Wax polish used on automobiles.
I had a very similar issue as yours. I tried everything and finally came up with a solution. And it was the liquid Wax polish used on cars and bikes to make them shine. Just mask all the sensitive parts of the area of your phone in which you have scratches, then take the polish and rub it on the damaged area with optimum pressure with a clean cotton cloth (make sure a little heat is generated due to friction) . You might have to do it several time so, protect any other unwanted part.
Hope this helps ?

[Q] USB rubber cover firm enough?

Hi all,
I've recently bought a DEFY. It works quite brilliantly and very fast.
I've noticed that the USB rubber cover of my DEFY is not very firm when closed. There is a little seam between it and the phone body, and the seam grows a bit thicker as it approaches the USB port side. I've included some pics of it.
Higher res pics are at
ishuo.de/images/defy1.jpeg
ishuo.de/images/defy2.jpeg
ishuo.de/images/defy3.jpeg
(Sorry I don't have enough permission to directly link pics here.)
I've also spilled some water onto it under a water tap. When I opened it I could see some water drops on the edge of the inner side of the rubber closer to the back.
I don't know whether this is normal or defect and I'm not sure whether it will stay up against water which is one of its great and practical feature.
Can anyone compare it with yours? Are all DEFYs like this?
Thank loads and happy holidays!
Cheers,
Shuo
When I close mine I am careful to press it in firmly as otherwise it looks "not quite shut." It has to squeeze in there. I presume this what's suppose to keep water out and as I have dunked my phone countless times without incident. However, if you think yours is twisted or bulging when seated, I don't think that's right.
Mine doesn't have that small hump when in place. I think there is some extra rubber under the clip.

yeah mines got that, you get the bump when the cover gets bent the other way when you move it to get the usb cable in
After charging mine looks like it will stay with the bulge like that when I put the cover back in place, but even so, I can press it firmly, and it actually snaps into place. Sort of even has a clicking sound. I only started noticing this as before I would press it in even, and the bulge would stay there for a while and slowly smooth itself out, but now if I press it in, and then press my thumb/finger all the way around the cover, it snaps into place very tightly.
EDIT - After looking closely at mine I see the hole is actually at an angle, so pressing it in straight would leave it with the bulge. You need to press it against the angle of the phone for it to snap into place.

exactly what i was about to say - works for me.
Wow you are so friendly guys.
Thanks lods! I'll look into it when I come back today!
I did get a slight feel of "snap in". Just dunked it shortly into water, and it still lives!
So I guess it's all right.
I get some moisture around the USB plug hole even when the cover is in place as well. Probably not a big deal. You can try using some grease to improve the seal as well.
Sent from my MB525 using XDA App
One review notes a small amount of "O-ring" sealant or grease around the battery cover rim. I supposed you could add a little. Just don't use vasoline, that's a pertroleum product and will degrade certain types of real and synthetic rubber.

My screen is now Rocking, Worn Pads?

Hey guys
So I have had my Z for 2 weeks and love it for the most part…faster and a crap load more enjoyable than the X10 it replaced. I am having some hardware issues however and was curious if I am alone on this one or others have had the same issue.
The hinge has become pretty loose now and the phone flops open regardless of what side I hold it from but in reality that is somewhat moot as who holds their phone from just one side lol?
The real issue I am having recently is the 6 little rubber stop pads on the underside of the screen’s left side/edge. Now there are 2 thicker rectangular stop pads on the right side’s corners adhered to the phones main body and the 6 little rubber pads on the left are attached to the screen and are there to compensate for the opposite rectangular pads so that the phone has both a buffer and a balance between sides so it sits flush, quiet, and secure.
Well somehow or for some reason those little 6 in a row rectangular pads have either pushed in too far to their respective channel or they have flattened via not regained their density/thickness as now they are flush with the screen’s underside and as a result leave a gap. So when I push, even lightly, on the center to left of the screen is makes a physical and audible click as it teeters down to touch the keyboard underneath and the right side compensates by lifting up and off the 2 corner rubber pads. Essentially the phones center area has become a fulcrum and I am sure that is not healthy on the hinge.
Has anyone else had this odd but irritating issue with theirs or am I alone here?
Perhaps I can try to find a thicker pad I can cut up to replace the strip of 6
I am alone in this one hey?
Lame...technology and I just don't mix!

No sir I'm on with you on this one. I started a thread about the annoying teeter or the screen a few weeks ago, and alot of people have it. I dont think its due to the pads, but more on the face of how the hinge is designed. It makes it so the screen doesn't sit flat enough. I know that they wanted to make the htc vision slim, but it caused some problems.
sent from my V I S I O N.
Interesting!
Thicker pads would remedy it while closed but once opened the thicker pads would not allow the screen to sit flush at the top of the keyboard
yeah, and honestly it hinders the device greatly because its so annoying. Oh well. Its okay! Still a great Phoenix.

well there's some guy who came up with a DIY fix on the dev section (I think) requires a lot of disassembly but looks worth it. I'd try it myself if I had all the right screw bits.
