I guess some of you may interested to mod your kaiser screen to tilt almost 90 degree, then you can use it on your car without any holder.
Here's a guidance document i pull together.
Remember, do it only on your own risk.
Enjoy!
Too scary for my taste.
Thanks! That's looks a little intimidating.
So basically is the only reason it tilts more is because the two plastic pieces are cut? What would happen if those two pieces were cut totally?
Thanks again.
A prediction...
Very cool mod, but I predict a large number of bricks on this one...
As a hardware design engineer professionally, I would have to recommend against this mod unless you are a technician and have access to the facilities.
If you are dead set on doing this mod, please take the time to prepare your environment - at the minimum, get an ESD strap and make sure you're properly grounded. Ideally, a strap and a mat are called for.
This is an ESD nightmare waiting to happen. Doing this on your kitchen table or coffee table - especially at this time of year, is literally Russian Roulette as to whether you will discharge 30K volts or so into the PCB and totally brick the device.
As a rule of thumb, if you don't know what ESD is, you probably shouldn't even consider this mod, or any other that involves opening up the device and exposing the PCB.
Just my 2 cents. Caveat Emptor, etc. etc.
Regards,
Jeff
nice..
i was thinking of something along the same thoughts, as it tilts, why have a holder!! just drive safe (as always)
exept, im still waiting for mine..
Wow! Nice Hardware mod tonychen! Just posting to register my shock and awe! Great writeup too!
@trick420: As can be seen, like Hermes, most sensitive electronics components are in a metal Faraday cage so this isn't as dangerous as it looks from an electronic standpoint. It's always a good idea to use a grounding strap however.
All those plastic tabs are gonna be a real bear to work with though. The TyTN only had a few but the Kaiser appears to be riddled with them.

I'm pretty sure everyone knows what electro-static discharge is.
so there are two bits of plastic going around the hinges that are stopping the display from tilting fully? like a tendon or do these bits of plastic go up against something to stop motion?
Yes you are right!
The ESD strap i guess is not available to most people except hardware engineers. The simplest way to discharge the static electricity is to wet your hands with a wet towel.

The plastic needs to be cut as it stop the two metal blocks to tilt up more. If you cut it totally, you still get the same result, so i don't see to much reason for doing that.

This is a great GUIDE!!!!
Thanks Tonychen.
Nadavi.
Not to be a killjoy but people should be aware that the plastic strips are there to prevent over extension of the thin ribbon cables connecting the display to the body.
You may not actually part these immediately but constant over extension will cause them to fail early.
Learnt my lesson years ago on a Nokia 9210i (stop that cursing there will you!!! someone had to buy them!) Smiles.
very intimidating but too scary for me. i would rather not break my $500 dollar phones just so i can see the screen go a couple more degrees more
just done it and its ace
slight idea change tho because its next to no use haveing it at 90 degree angle unless in car, not cutting away plastic compleatly makes it a little stiffer and will only be able to make the screen angle to 90 by choice so you shudnt break anything as you wont do it all the time. just a thought.
very nice mod.
this is going to be off topic though. " is there anyway we could tighten the hinge? mine is getting loose already.
Just a thought but isnt it alot easier to rest the back underside of the phone on a small object. this will tilt it forward and make the screen visible in the same way... You could use a small velcro patch to secure it to the said object which in turn could secure to the dashboard etc in the same manner. Alot less scary to do and you wont run the risk of damaging your phone.....
Pretty cool, but idk about messing w/ the structural integrity.
I always thought ESD was a myth. I've been working on computing hardware for almost a decade, and I do take the necessary precautions when working on new/mission critical equipment. But 90% of the time I am working on refitting relatively old workstations/servers where my boss has basically told me he doesn't really care if these items make it back into active service or not, so stuff like that I always go commando on, and I've never had a single piece of equipemnt go spontaniously DOA on me while handling it. (i.e. every single item of equipment I've retired due to DOA was reported as DOA before I touched it...)
Oh, and I have a mini tesla coil in my cube... j/k
Here is my tesla, got bored a couple weeks ago and made one, its like my fifth one.

Who's daring enough to try this on the new Touch Pro 2?
Hi, i recently got my HTC KAISER,
unfortunately, the case that came with it to me is terrible, until now because of it, the phone fell from my hand 2 times until now. i have a feeling that the hinge is a bit loose from the screen. does anyone know how to tighten it back to the screen? from the right hand side there is about 2mm gap, and it makes a sound when i touch the screen since it hits the back.
any help, is appreciated.. esp if they are productive.
Thnx in advance
How can we help fix it if it was dropped? You didn't even provide any pics of it and I highly doubt we can help you. If its damaged its damaged, and your only course of action is to take it back and see if its under warranty and cross your fingers. I wish you the best of luck and hope someone can repair it for you. As far as the case I totally know how flimsy they are.
What does this have to do with XDA development?
Try the ATT wireless forums. This forum is for development.
what a couple of unhelpful posts, have we no mercy? this forum is full of topics that are 100% kaiser but 0% development, why are you picking on the poor guy with the (possibly) broken phone? and why direct him to some AT&T forum when he's already said it's an HTC branded phone? if you're going to kick a man when he's down, at least read his post properly first.
to the op: I feel your pain. in my first couple of weeks with the kaiser I must have dropped mine a dozen times, I think it's something to do with the extra weight. anyway, I too had some issues with the screen afterward - at one point their was a definite gap between the screen and keyboard as you described. I really noticed it and worried at first, but after a few days use and pocketwear, I found it pretty much closed up by itself. similiarly, i've found times where the top half of the phone has become misaligned to the left or right, so it overhangs slightly - this can be cured with a gentle but firm push the other way. I think the whole mechanism has been designed with a bit of give in it, so it can take odd knock without shattering, but still be nudged back into place without any real damage done. My advice - keep using it, slide and tilt it a few dozen times, and see if it falls back into shape. if it doesn't, try a firm but gentle push in the right direction, and if *that* doesn't work then take it back. but don't take any nonsense in the shop - insist on a warranty repair.
What are you talking about? I was blunt and straight to the point with the op. I told him we can't do anything and where he needs to go. I'm not gonna hold someones hand and tell them everything is gonna be fine and there's light at the end of the tunnel. He made a thread with NO pics to even show us what is going on so are we suppose to guess?
You don't have to be a customer of ATT forums to post there. The Kaiser design and the Tilt design are identical except for logos and the front cam.
The discussion would probably be better there instead of xda-developers

there may be people on the forum that are famaliar with taking apart the Tilt and tightening the hinges. this is why he posted.
Thnx for the support
Thnx for all of the support until now....
i am begining to accept the fact that i can bear the hinge problem which might not be a problem since the aligning is ok slightly loose, but today in the morning, i noticed that after the fall, the "start" button of the keyboard is sticking out, is there anyway to stick.fix it back in like the rest of the keys (something similar to the laptop buttons, by pushing it in, in a way??)
thnx for all of the support.
There is a thread around here some where that has a ZIP or a link to a PDF file that shows you how to take the phone apart. The reson for the PDF was to show you how to make the screen tilt even more than what it does stock. Search for it, I dont have the link, but I have seen it and read it on these forums.
pls
any ideas concerning the keyboard problem?
The start is not in its place no more, it is somewhat hanging...
plssss help...
thnx

As am I. Again. We're not mind readers. If you have a hardware problem you post pics and point-out exactly what's wrong so people can trouble shoot it. Take it to at&t like the first post suggested. I think a few of you need a cab that installs common sense before you post.

The dismantling guide that Grizzley refers to is available here (Tonychen's guide):www.mikechannon.net (in the manuals section)
To the posters that don't like the OPs post:
If the post had been made in the Upgrading Forum then I would join you in saying this is not a development or upgrading matter. However the post was made in the regular Kaiser section and is therefore a completely legitimate post. In fact, we have a tradition of trying to help those that want to dis-assemble their device for whatever reason. Even if they don't, but just need more info on the mechanics of the device then that is ok too. Thinking of the TyTn/Hermes, a fix was found for the loose keyboard problem via dismantling procedures and physical examination of the device. Problems can be physical as well as software related, so don't be too narrowly focused in this general Kaiser forum.
I do agree with those that say you must give full details and pics if at all possible with this kind of problem, otherwise we are left guessing and possibly wasting time suggesting things that maybe inappropriate.
Mike
Pictures are here
Here are the pics...
look at the "start" button, it is not completely removed, it is hanging on like this....
look at the gap from the right hand side (Power + camera button side) is bigger that the gap from the sim slot side, therefore generating a plastic tap sound when pressing on the screen from the right side. as you can see in the pics, the gap is bigger than the paper clip size.
any suggestions for reducing the gap, and fixing the "Start" button?
any suggestions?????
help would be appreciated!
Ok, after seeing what's wrong you def need to take it back to the store you bought it from. Ask them if they can sen it out for repair. They'l most likely give ya a temp phone til it comes back. Now, it's probably not gonna be covered for obvious reasons, however, it might be cheaper to have them repair it rather than buy another one. Worst case scenario you could replace it with a refurb. Refurbs are excellent and some you can't tell if they're refurbs to be honest. Cost is approx $149, plus shipping. Let us know what they say when you take it back.
Other than taking it to the store, any possible suggestion that i could take action on by my self to fix this issue quickly?
because they will ask me to leave it with them for a couple of weeks!
I know cnn.cn does sell replacement parts, if your willing to do the repair yourself. Sorry I cant help anymore

jon_k's post was over 20 days ago, and he's already been corrected by a mod. Before this gets out of hand, let me remind you to not feed the trolls!
With the help of the link above you will be prepared to open the Kaiser. OK, you have to have the tools mentioned and do take a deep breath before you start, but as soon as you start the process is simple. Print out the photo's and write on the paper the colour and type of the screws you removed.
The glued on case above the battery compartment is the meanest of them all to remove and thats where you start with. So when that is done in about 5 minutes you can discover the buttons from the inside and in 10 minutes you come to the hinges where you find a total of four philips screws to tighten.
Beware for one thing though. The black plate which holds the slider system is held by six torx screws. Check them too, but don't tighten them too much or you will end up with a broken screw. Guess how I know
Regards, Roel
Hi crew,
My D4 (and I) recently had a run-in with a pint of Guinness (thanks, waiter!).
No damage to the phone or keypad (thankfully), but the sliding mechanism is now a little 'tight' / resists more.
Am thinking the inside/pads are just sticky, so I've tried to carefully water/windex clean the rails and slide back, which seems to have helped slightly.
If anyone has a guide or info on how to properly clean the rails / sliding mechanism, it'd be greatly appreciated.
Thanks in advance,

I've not tried this, but I would have thought switch lubricant would work pretty well. I sprayed a shed-load of it all over my D3 to try and get the keyboard working more reliably, and it never did any harm.
Cheers,
Steve.
I currently work for a company servicing all manner of devices and can tell you water damage is a nasty beast.
Even if your phone seems fine now, days, weeks, even months later it can have serious issues if not properly taken care of. Corrosion is a very slow killer in most cases, fair warning.
All that said, if your dead set on not taking it somewhere then you need to watch a disassembly video online and address the root of the slide track issue (which is most likely lint and dirt turned to goopey sludge from the beer.)
There is no quick fix, and any kind of lubricant will simply make the issue worse in the long run, and even if it helps at first. Once the phone is off its hinge you can use goo gone or any type of mild solvent to clean the tracks.
I see this sort of thing on a daily basis, and while there are always exceptions to the rule, play it safe and assume you're not lucky.
ifixit dot com has great resources to check out. Good luck, let us know how it goes!
Hello, looking for a broken/borked/dead HTC One to attempt a different disassembly method to try to help the One community.
It is my understanding that they are glued together, not screwed, and that the suction cup method does not work. I used to retrofit headlights that also used glues, some heat glues, some needed a solvent. I have a lot of technical skill, and i would like to try my hand at popping one apart WITHOUT destroying the case/screen. I dont care if its water damaged, cracked screen, whatever, as long as its intact.
Posted this in all HTC One sections, please PM me if you have one or know of one, i'll pay shipping to and fro (i will NOT attempt repairs, JUST non-destructive disassembly) and post the results and a video on youtube if successful, and ship the unit back disassembled if successful, and not damaged further if not successful.
Please PM if interested or if you have any heads up to exchange contact information.
Thank you,

if it was chlorine water, the corrosion will kill it., but some of the hardware might survive. connectors would all need cleaned.

I think there is, iFixit said themselves their repair was a butcher job. They also didnt say whether or not they were able to successfully reassemble. I'd like to know if there's another way, perhaps using a scientific hot plate or as the you stated in the OP, a glue solvent that wont hurt the components. I hope this is not the the wave of the future with equipment..."Disposable Expensive Phones"...or Assurian gets more popular selling their plan and sending 75% crap... BTW, I agree with the nonbending of LCD/Digitizers...I see so many tutorials showing this.

definitely still interested.
OK, I have found the issue that causes the touchscreen ghost touches, unresponsive touchscreen, etc. This guide is short and simple, and is provided with NO WARRANTY, TO BE FOLLOWED AT YOUR OWN RISK. This guide requires that you open your device WHICH VOIDS THE WARRANTY. Those of us with the original grouper/WiFi/2012 version are well outside our warranties, so that really doesn't matter now.
To explain, our devices use (to my knowledge) an actively driven capacitive touchscreen sensor. It has been narrowed down that a significant number of devices suffer from a grounding issue where the voltage potentials between the case and screen will cause a number of touchscreen issues when the device is electrically insulated from the person touching the screen. There are many YouTube videos and guides on how to diagnose if your touchscreen has this issue; I will not detail those here. To be simple, if you set your device on an insulated surface like a wood table and touch the screen with ONE HAND while not touching the device with your other hand, the touchscreen will go ape**** on you.
For those of us suffering these issues, it can ruin the entire experience of the tablet. I have deduced through a logical process the location and cause of this issue, which I will detail in the guide below.
The nexus 7 uses a filmed metal back, which is mechanically grounded to the motherboard via two "blind" gold spring contacts on the motherboard which touch the filmed metal backing of the case back. I call these "blind" contacts because there is no corresponding electrical contact for them to sit upon, simply the material of the case itself is what they contact when the case is closed.
What you will do by following this guide, is physically break these tabs off the motherboard, thereby breaking the circuit of the faulty ground point. The reasons this is successful in resolving the touchscreen issue appear to be twofold; first the ground points wear off the filmed metal of the back QUICKLY due to flexion of the plastic case back and therefore end up forming a SECOND capacitor on the device case back. This causes electrical potential to build between the plastic case back and the device itself, causing unreliable reading and operation of the capacitive touchscreen. Second, the intermittent ground connection causes unreliable grounding of this capacitive potential, which is worse than no ground at all in the respect of a capacitive coupling of the case back and the device.
These issues could not and cannot be resolved by a firmware flash, because it is a physical problem. Asus could not resolve the issue completely, because even if all components involved are replaced the issue will arise again due to the way the device is constructed. It was simply a poor design.
So, to get to the meat and potatoes of the fix;
1.) Pop the back off your nexus 7. Locate and REMOVE THE BATTERY CONNECTOR to prevent any possibility of a short while you follow the rest of the guide.
2.) Locate the two blind gold spring pins on the bottom right corner as circled in red on my attached picture. Note how they do not have any corresponding connection on the case back as the WiFi GPS Bluetooth and NFC antennas do. This is because these points were meant to found the case back to prevent exactly the issues we are seeing. However due to poor design they have become the CAUSE of the issue.
3.) Most simple step: break BOTH connectors completely off the board by gently bending them back and forth until they snap cleanly off the board. There is no chance of trace damage when doing this - the solder is MUCH stronger than the super thin spring connectors and they will easily break cleanly at the solder joint. If you do not break BOTH off, the touchscreen will get WORSE because you have simply enhanced the ability of the case back to form a capacitive coupling with the case back. So break both, or do not bother.
4.) Replace the battery connector and case back, ensuring you do NOT damage any of the other fragile gold spring connections, if you do you will lose some of your antennas and these connectors are a pain in the ass to replace.
I have attached a picture that shows the two points that need broken off the board circled in RED.
That's it, you're done. Reboot the device and enjoy a touchscreen that actually ****ing works. You're welcome.
Again this guide is provided at your own risk, I am not responsible for anyone who breaks the wrong connector despite my detailed guide, and I am not responsible for any other damage your fat fingers might cause while dicking around inside a sensitive electronic device.
I understand if some are too squeamish to attempt this guide, but I respectfully request that those afraid to attempt do not bother ****ting up the thread with useless posts. Constructive comments are always welcomed.
If this works for you as it did for me (I.E. perfectly) please hit the THANKS button!
I'm also currently unemployed, so if I've helped you and you are better off than I am then donations to my google wallet account are HUGELY APPRECIATED!
Once confirmed, I would ask that the mods sticky this thread.
Post reserved for future use.
And the dumb ****s at Asus tech dept. of course couldn't figure this out. Never again will I give Asus a dollar for anything.

Even if they knew exactly what to do the company is not going to allow them to "damage" devices in order to fix them. That's how Asus would see it, as damage. It is against the original, albeit flawed, design.

They don't do **** to fix anything, I sent them one, a 2012 N7 and they did absolutely nothing to remedy it, re-flashed the O/s or some such crap. I came up with a partial fix myself.
Just out of curiosity, have you done my fix and can you post confirmation so we can get the mods to sticky this thread?
As much as I'd love to get everyone's old n7 for dirt cheap when they think its "broken", I'd also like to see us snub Asus with our own permanent real fix as opposed to their bs runaround they pull until the warranty is up.
So please do confirm if possible.

Hi, Just replaced a broken screen few days on it with a new one and got lots of ghost touches and non responsive spots.
So I tried your suggestion and it works for me , I took a less destructive approach and just put some tiny pieces of duct tape on the back cover where the connectors touch it instead of breaking them off.
My new screen is in place and working properly :good: .
Thanks.

Mods please make this a sticky thread at your convenience, I believe this info will help a large number of N7 users, and it seems like according to the user above that it works when done in a non destructive way as well.
I ve had the same problem with my touch screen, it only happened when i connected the back cover of the nexus( i had a screen change)... so before i try to break the 2 pins i ve just put some electric isolation tape (plastic) and touch works like a charm.... thanks!!!
Be careful what kind of tape you use, some tape could make it worse.
You're welcome.
If anyone else has succeeded using this method or using tape, please post your results. I'm going to assume it hasn't harmed anyone or I'd have heard about it already.
Will attempt this tomorrow and confirm back. Using tape method.
Carried out the tape option, along with other additional fixes. Wipe cache, turn off animations, limit background processes to 3 and others. Seems to be working for me perfectly now.

Sorry.
Brilliant!
Finally I can now use my Nexus 7. At first I thought the erratic touches were due to the oil on the screen but upon replacing the screen protector, the erratic touches are still present.
Tried taping the contacts with a tape (A simple electrical tape would do), and much to my surprise, the device is usable now.
Also working for me, i just broke the pins. Much better now!

Tested the tape/isolator option (less hardcode) in my "bad" N7 (the other works flawlessly and they were both bough day 1, maybe different revisions, not gonna open that one incase!), and the ghosting hits and touchscreen ignore problems seem to be completely gone.
Thanks a lot!!
Thanks so much for the fix, it's a new tablet now. I confirm this works by using isolator tape over the pins. Very easy fix, took me 2 mins to do it... would have liked to know about it sooner
Thanks, I already had managed to solve partially the problem placing an aluminium foil into the tablet (risky and complicated so didn't posted), but this is easier and WiFi reception is better too. Anyway it is not perfect yet, same problem than my solution: try crossing axis vertically or horizontally (only one hand, tablet on a table) and weird things happen like no touch detected, very fast touchs, etc... I will post here if I figure out something else.
