Has the Z1 compact a anti shatter film on the backside - Xperia Z1 Compact Q&A, Help & Troubleshooting

Hello, as you can read in the threadname, my question is, if the z1 compact has a anti shatter film on its backside. And does anybody know wich material it is. Plastic or glass? I own the european model.
Thanks a lot

European version has plastic... And there is no any anti shutter sadly you need to remove back plastic panel of you want change

Unfortunately I have tried to peel the film. So the bravo of my phone looks very ugly. Now I have to order a new backcover for assembly. Any tips or tricks about it. I know there are many videos,but..... I am a little bit angry about the water resistant of the phone,if I assemble the backcover.
Film is included an preinstalled on the inner surface of the backcover. That's good to know.
Once again any tips or tricks?
Thanks allot

Only advice from me is that you should go to company which is official service and check how much it will costs to change backpanel (you should by glass one) it will do on warranty and should keep water resistant(I think) but you can give it a try if you have something that in your city

Maybe putting on something like that is an alternative: http://m.ebay.de/itm/121335821880 I find it quite beautiful on mine, optically as well as haptically.

- Make sure the plastic frame surround does not lift at all along with the back, or you'll end up ****ing the frame glue and it's goodbye waterproofing and hello phone that creaks when you hold it
- There's a reason why professionals use an evenly heated flat surface - hairdryers/heatguns/similar will increase your chances of ****ing the frame glue
- Use isopropyl or similar to get the internal surface absolutely clean
- Heat it again slightly after applying the new back
- Apply loads of pressure (eg put it under some books)
- After it's all dried, make sure you can't lift the back AT ALL if you put your fingernail in the groove above the LED flash. If it lifts you will end up with a foggy camera lens from normal use and a ****ed phone if you expose it to water

Display protective film

Hi i've found in Toch package one film with the same shape of display,someone know if this are spare part or is additional protection and should be placed?
Today my friend show me his Htc touch with this "film" placed and so is start discussion with him about the use destination.
Thank you in advance.
It has to be placed as it is called a screen protector. Not using one would lower your PDA resell value has you will probably get scratch on your screen after a few weeks.
Be carefull when setting this up, as it need a very clean screen, and a dust (nearly) free environment. A bathroom after a hot shower is the perfect place to set this up.
Yes, it is a screen protector. It is a bit ticky to fix. To make it easy to align you may sprinkle some water on the adhesive side and apply to the screen and align. Gently press out thewater with a stiff paper and also to displace air pockets. If some water droplets still remain under the sheet do not bother. It will all dry out within 3 days and result in a clear bright screen.
Thank
thank guys, was thinking is spare part because the default protections of display look like removable and so i've supposed replacement part.....but wasn't
Ok just placed
I'll have mine by the end of the week.
I store mine in my pocket and it seems the protector would peel off from repeatedly taking it in and out of your pocket since the screen is flush.
Anyone have any experience with this?
Does anyone knows if these HTC protectors (not some cheap 'fits all' protector) can be bought seperately? I applied mine right after i've got my phone it but was a bit sloppy with all the excitement and when re-fitting it some dust got underneath it, leaving me small airbubbles. If anyone has a link to how/where, it'd be much appreciated.
you can remove it, wash with some soap and then apply it once again, no need to buy a new one.
The HTC ones can be removed, washed and re-applied too? Can someone confirm this, coz I only read this could be done with the better ones from expanys or something
where to buy protector film?
T-mobile told me to go to dangaard.com
but i can not find the accesory's for the touch and the site is only for store's
so i went back to the the store asking if they can order the screen protectors for me the did not want to order it for, but i got one extra from there demo model, so my tip is.. go to shop and ask if they have spare protector from the demo model
How about the exim screen protectors? I have heard that those are "high quality" films... (pda-now.com)
expansys has some good ones, PPCTech and ORA: http://www.expansys.com/a.aspx?i=149713&atype=SCREPROT
Proporta ones are decent too www.proporta.com
Wondering if anyone try this
http://cgi.ebay.com/CP-FULL-BODY-SC...ryZ15036QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
Really want to know how good they are, they claim to be totally protective. I am a bit skeptical, any thoughts?
I have been very happy with these skins from Boxwave. Very easy to slip on when needed. Used these with my Trinity as well. I have not tried the ones with the cover. The Touch with skin is still smaller than the Trinity.
http://www.boxwave.com/products/flexiskin/flexiskin-htc-touch_2727.htm
Edit:
Just noticed they offer a Skin + ClearTouch screen protector package
http://www.boxwave.com/products/bun...skin-and-cleartouch-bundle-htc-touch_2727.htm
This is something similiar to what I post earlier, they warrant for the life of your device that you will never get a single scratch on it after you provide their full body protective film. Wouldn't this be cool, without the bulk of a case, yet, still achieve the same protection. If anyone have a chance, browse thru their site ,they have a video demonstration to show u the force thatf film able to withstand.

I'm interested to know this too, is washable?
Some photos...
I personally don't like the front cover, the shiny effect doesn't look right in this phone (at least for me), the back cover is fine....
The installation is more or less easy, after some minutes the covers really stick to the phone, if you don't like the result you can remove very carefully the covers, wash them and repeat the process again
Pros:
- Removable and washable.
- Resistant (apparently).
- Inexpensive.
Const:
- A bit shiny for my taste.
- Good for scratches but not to drops
--------------------
Talking about the original HTC protective film... Yep! it is washable
What the.....CONDENSATION!!!!!

man! are u really serious. i mean a bathroom and especially after a hot shower wud be the last place i wud attempt to do something like sticking a protective film on my PDA. i mean think a little science man. after a hot shower condensation [stage when the vapor above cools back to liquid] is surely a threat inside a bathroom, and while you try to stick the film, condensed vapor or mist to be precise might come in between your pda and the film. then all you will ever have is a smudged all white screen which you cant wipe off even, cos its between the layers.
so i m jus telling you cos i had seen a lot of incidents like this specially where hot vapor just cooled off is around!!!!!
No harm done! Just my scientific mind thinking a lot!!!!!!!
.....
i did a post some days ago about shieldzone. i used the invisible shield for a couple of days and the only thing thats really terrible is the reflection of the cover, as you can see in the pix abough.
so i searched again for a good display protection and bought a product from 3M, named vikuiti, armr200. for me its the best i ever saw.
# Anti-Fingerprint Layer
# 2 times Anti-Reflection Coating
and a very strong material.
i tried a lot to scratch the layer, but it was not possible.
Look at this, its a german site. if you google for it you'll find a site in your language for sure.
http://www.schutzfolienscout.de/vikuiti-armr200-schutzfolie.html
I have the 3M Vikuiti, armr200 for my Fujitsu P1610. It works quite well, not totally clear like those crystal clear type films, so you will lose some contrast and clarity, but for anti-reflective, it's the best you can buy. (and it's quite pricey).
One bad thing is that it reduces outdoor visibility quite a bit, you'll need to crank your backlight for outdoor use.
And it still shows fingerprints, actually they are quite noticeable due to the AR layer, but it's much easier to clean than other AR coatings.
One thing though, unless 3M is going to make one specifically for the HTC Touch, it will be a PITA to cut to the proper shape, since the clear cover is not a rectangular shape.

I wouldn't worry about it, I've used the steamy shower "poor man's clean room" technique many times, never had an issue with condensation stuck under the film. If anything, any liquid will help to avoid air bubbles and can be squeegeed out. Some films (namely 3M's paint protection films) require liquid to install properly.

lens cover damage

The see-through (plastic?) lens cover appears to have a thin layer on it, a layer that comes off easily? i can remove it with my finger nail with repeated rubbing so it can't be an anti scratch layer
It's not really like scratches it looks more like it's just being rubbed off and the surface below looks not as shiny.
Do others have this or have had this?
Anyway on mine this layer is mostly off in the middle, bit of a pisser it probably effects the photo quality..
yes, this happened to me. I got a scratch on the lens cover and the "coating" started to rub off around the scratch then. Once it's broken it will all eventually chip or rub off. I was left with a dull not so transparent lens cover. crap photos.
I got a new back cover for 30euro! (argh!!). Now I do not rub my lens and am very careful. The initial scratch was caused by a tiny piece of salt or sand on the lens when I rubbed it clean with a microfibre cloth. Once it was scratched the protective film just flaked off really easy when I rubbed it even lightly.
Get a new back cover and be very careful when rubbing the lens cover in future. In fact DON'T rub it is best. If you do get a finger print on it very very lightly use a microfibre cloth to remove it. no hard rubbing.
bummer.. i'll just leave mine i think, maybe some one will bring out a better version, or i could maybe maybe stick a plane glass disc in.
yeah, it sucks doesn't it! I would not mind paying an extra 20euro for a desire if HTC would coat the lens cover with mineral glass or something so its much less likely to scuff. plastic with a coating is useless.
anyway, good luck if you replace it with a glass disc, that would be cool too. I splashed out for the battery cover, but it was expensive and wouldn't do it again if it happens.
Thats why I loved my Nokia N82. It had an actual lens cover that kept out dust, fingerprints, grit etc.
well, HTCs next big handset release will only be improved I imagine.
Same here
I've had the same problem, bad engineering on HTC's part in my opinion as the lens(cover) is a very much exposed part of this particular phone because of its 'bulgy' design. Never had this kind of problem on my Cybershotphones.
Too bad though as I'm otherwise very happy with my Desire (although it would have been nice if the screen were a bit less prone to scratching, gief Gorillaglass).
I ended up rubbing the lenscover until the entire coating was actually rubbed off in the hope pictures would be less blurry because of the partly chipped off coating.
Anyone know what the coating is for in the first place?
if this happens to mine I will drill the clear lens out

I think you can just bash it out - there's a post on the forum somewhere about it

The ultimate oem look and protection...

I've been playing around with films lately, most screen protectors are crap these days. I wanted something industrial grade. Long story short, pulled off some extra clear bra from a sheet I did my car with. The results are 10 fold better. I used xpel ultimate self healing film.
https://www.xpel.com/products/xpel_ultimate_paint_protection_film.asp - the film really is self healing
Tools
Screen roller
Xpel ultimate film - order a decent size you will need extra.
Exacto knife
Very clean work area
Patience & precision!
Installation
1. Clean surface, no dust!
2. Cut film about 3 inches over the size of the actual template, you will leave fingerprints. You need that slack so you can grip it and then cut off the access where you gripped it.
3. Lay it down from top to bottom, this is the most important step. You cannot stop once you start, if you stop you will leave a crease line. You must take the roller and push the film down slowly, consistent but never stop.
4. Repeat rolling until all air bubbles are gone, there should be almost none the first time around. You do not use water with this application.
5. Trim the slack off with an exacto knife. Make sure not to cut in too hard, you don't want to cut into the phones waterproof seal on the edges.
6. Admire your work and of course do a light water test to make sure your z1 seals are good.
Pros
10 mils thick
Self healing - scratches disappear.
Very glossy
Super smooth
Fills in scratches underneath on the stock protector.
Oem look
The most durable out
Grippy on flat surfaces
Cons
Pricey
You have to be good at installing films - you really need a roller or be very consistent. You only get one shot.
You have to trim everything your self
Sounds interesting (really wanna try on my....motorcycle!) But what about fingerprints?

They do show finger prints but wipe off very easily, I find the problem is you can't have both fingerprint resistance and scratch resistance. This film is very soft and grippy. It's very durable, that said I only have it on the back. On the from I spigen Glas Tr Slim. I love both but for scratch resistance the xpel wins hands down.. the problem is that it is slightly textured as you can see. That definitely can take away from the screen clarity. That said... I have the whole back covered including the camera and no distortion of photos or ghosting of the flash.
Now fingerprints on the adhesive side is a problem, thats why I said you absolutely need slack when doing this. Once it's on though it's worth it. I scratched it this morning and just like the video, ran the phone under warm water; Good as new! I actually like the subtle textured gloss of the back. It really adds a nice touch. You can order custom sizes from xpel, not sure where but it's on their site. I sized up my headlights that way.
Basically my setup is...
Spigen Glas TR slim in the front.
Xpel Ultimate Film in the back.
Oh, doing bikes with film is a nightmare... flat surfaces are 10x easier. I'm a professional detailers but when it comes to clear bra's I let the specialists do it. Tint's and Films are some of the most tricky applications in the automotive field. Anyone who says they do it all... usually isn't good
I hope this info helps.
Thanks for all the info. Yeah I guess it would be a pain to do my bike, my tank shape is a bit complex. I don't think any shop does that where I live (Hk)
If I can find a cheap way to get it oversea I'm gonna try it on my z1 back, right now I'm using a nice textured back film protector I found in Japan...

Custom metal back cover

Considering the new xperia x has one and that the back cover on the z3 is easily replaced, wouldn't it be a great idea to give your old phone an updated look by just putting a custom back on it!
Can be done. The camera plastic cover is glued to the back cover from the inside?
isn't it like a Faraday cage? does it kill the wifi + mobile signals?

Shouldn't kill them (maybe it will be tricky with NFC). The thing is that the frame around the phone is plastic, so that should be enough for the WiFi.

THat's a good idea. I thought about it and was wondering about the Faraday effect. But then again I would settle with anything that is not glass to be honest.
I'm sure that anybody with a CNC could make a custom backplate in POM or any other resistant plastic...
Now to find somebody on the forum with a CNC and spare time!
I made my own in acryllic plastic.
1. Cut out in 1mm acryllic sheet using the old back as a template and then cut with Exactoknife(Needs to cut/draw a line several times with exactoknife, acryllic is tough to cut, also needs to be sanded down to same size as old cover. Sanded evenly and not to fast to prevent friction heat that messes up the acryllic)
2. Take out camera lens from the old frame (Adhesive tape, easy to remove with exacto)
3. Drill a hole for camera lens using old back as template.
4. Sanded both sides from 80 to 120(Wood) then 400>600>800>1200 Silicone carbide paper(Wet)
5. Heated it up evenly with a flame on both sides to give it a darker smoked color then stuck it between two flat objects to prevent it bubbling or deforming until it cooled down.
(Heated back and forth so it didnt get too hot and had time to cool)
6. Once cool, washed with water.
7. A few smooth strokes against 1200 Silicone Carbide (Wet) to even out any irragularities
8. Dried, then a few smooth strokes with 1200 Silicone Carbide dry, sideways to have an even pattern and smooth surface.
9. Took the camera lens, glued into hole. Let dry then 1200dry sanded around camera hole to remove glue residue. (Dont sand the camera lens or you have to polish it. Major PITA..)
10. Took the top part of the black sticker from the inside of the old glass cover, cut out the top camera part as a square and stuck it around camera and flash to prevent flash bleeds.
11. Reapply new adhesive tape to the cover and reapply it and voila, waterproof again
This is my 3rd, made it last night, rushed job as I was tired wanting to sleep, so did not care about looks.
Also couldn't find one of my previous glass covers so I had to reuse the camera lens and sticker from the old plastic cover.
Resulting in the camera lens outer ring breaking off and the sticker being semi sticky and filled with bubbles. But it functions, which was the main idea.
Didnt bother about sanding it decently so there's still scratches, but it gives you an picture what it looks like.
If done properly and more patiently you can get a smoother texture, no air bubbles and a non broken lens, but once superglued that lens is stuck rocksolid.
Hey guys, is there a drawing of the back cover available?
I would like to try a 3D-print, after the second back cover is broken.
But I don't have a radius gauge and need the radius of the corners.
Thanks for your help.
@mike the pike
what a coincidence!
I have made a modell in FreeCad because I had the same idea like you. But I don't have a 3D printer, so my plan was to order it from a german company which offers to cut parts out of plastic plates.
I'am not a drawing or CAD profi, in fact this was my first experience with stuff like this, but I am pretty shure my modell is quite accurate. My only opportunity to test it, was to print a 1:1 sketch and compare it with the (broken) original backcover.
Feel free to use and modify my work, but please tell me if it works. :highfive:
Doing this, part one
I spent some time in the machine shop on campus yesterday, and, with the help of the assistants, made a metal back out of sheet aluminum.
The toughness is far superior to glass, and the strength is, too (the glass used on the Z3 Compact by default is somewhat pathetic).
From here, I was planning to first apply a brushed finish with an abrasive pad and WD-40 (thanks, YouTube) then either anodize (time to steal a HVPS from a hardware store?) black, or pay someone to apply a thermoset powder coat. Anodizing would probably yield better results, and be cheaper, but the scratch resistance on the aluminum is a bit low, so thermoset would help a bit. Oh, and the bottom left corner is a little bit off. Might get some silicone caulk and apply at the corner for waterproofing. Otherwise, it turned out extremely well. Filed down the corners myself to get the perfect fit.
One problem that I have is the flash. The normal back glass is a plane of glass stretching across the LED in the back. Will either 3D print it, or, more realistically, just stick a spare Z3 Compact camera lens cover on it and call it a day. Any other suggestions are welcome.
Also, I'm not allowed to post images, since I made this account for this . If you're interested in the result, PM me.

P.S.: NFC doesn't work but reception is perfect.

I assume that the glass they use for the camera lens is of a convex design such to scatter the light intensity for maximum coverage of the subject. It won't be so easy as just using any untreated material unless you want a dull-flash. Assuming you've already made your cuts to good tolerances, then why not just source your adhesives from the OEM itself? Save yourself some work. The proper way to apply those adhesives(as such to retain the water-resistant nature) is to use a hot plate up to 100 C and place it on the plate for a few seconds before pulling it off.
I'm mainly worried about the cut at the bottom left. It's not at all made to a good tolerance. I did buy the adhesive sticker, and I plan to use it, but some silicone wouldn't hurt on that one place.
Also, there is a bit of distortion when I look through it, so you're right. Not much I can do about it, though, but pray to the gods of diffraction.

Sorry, I didn't visit this site quiet a wile.
I lent me a radius-gauge and I think I found some good values.
Unfortunately I don't have them in mind, because I gave them to a colleague, how will 3D-print the cover for me.
As I only made hand-drawing, he will transcript it into any 3D-data-file, which I will provide you here, as soon as I received the results.
So stay tuned.
The cover for the camera is still usable and I plan to insert it into the new back-cover, but I'm quite at a loss about the flashlight.
p.s. Yesterday I mounted my 4th back-cover

Mission complete
Hi all!
I finished my metal back cover. Still a new user, so can't post images, but I just wanted to let you guys know that I completed it and the phone is 100% functional (aside from NFC, RIP).
In the end, I anodized the aluminum and used a thin plastic sheet sealed with superglue around the flash (flash works fine BTW), and gave it a little brushed finish afterwards that cut into the anodized piece ever so slightly.
I'm very happy with it, the finish on this phone is unlike any I've ever felt. Smooth, yet solid, soft, yet sturdy. The phone is cool to the touch when in standby. The camera was a bit wonky at first, but as I pressed down into the metal back it stabilized, and now seems very resilient. The anodization itself didn't go all that smoothly (took four tries), with the metal part itself ending up with an uneven finish. It being black and brushed helps, as the texture undulates, making up for the inconsistencies.
I made a post to /r/Android with images and more details. Same username as on here. Go check it out if you're interested.
Eric
Mission also complete
I finished now my 3D-printed backcover and it is quite satisfying.
I made it by using the file railpl posted.
Unfortunately it is about half a mm to short so there is a small gap on the short side, but for me it is okay.
I used the lenscover from my old glassback and drilled a tiny hole for the flashlite.
So I think it is not waterproof anymore.

How to properly apply Nillkin tempered glass on Asus zenfone 3 ze520kl

Ok so you bought a zenfone 3. Beautiful little piece of hardware isn't it ? The glass and metal design looks premium alright but it would be a pity if you got the screen all scratched or shattered. Remember that gorilla glass 3 is scratch resistant not scratch proof and it can be scratched quite easily by dust particles and sand. Also it can be easily shattered like any glass. Only sapphire glass can be called scratch proof but you won't see sapphire glass mass produced for smartphones screens any time soon because it's too expensive and very difficult to produce for larger surfaces.
So the best way to protect your precious screen is by applying a sheet of tempered glass. It has a higher scratch resistance than gorilla glass and it is designed to shatter on impact to dissipate the shock energy that would otherwise destroy the screen glass. It is very easy to apply on smartphones with flat screen surface but there's a catch. There is a new design that's being implemented on smartphones screens for a while now with curved margins and all which is generically called 2.5d glass. Zenfone 3 features such a screen. So what's the problem you may ask ?
Well long story short this means you can't apply a flat tempered glass on a screen with rounded margins without the manufacturer being forced to reduce its dimensions to only cover the flat surface, unless you can find a manufacturer that produces tempered glass with curved margins. So far I could only find such screen protectors for the Galaxy Edge series. They are nowhere to be found for our beloved asus zenfone 3 for example.
So yeah there are plenty of flat screen protectors for the zenfone 3. I myself got one from Nillkin. It is carefully dimensioned to only cover the lcd on the left and right margins. Problem is that the curvature of the screen starts somewhere from 1-2mm from the inner side of the lcd depending on the manufacturing tolerances. This means that even if you perfectly position the tempered glass there will still be 1-2mm on the margins that will hang in midair because it can't stick to the curvature. From what I could find this issue is commonly referred to as the "halo effect". And it's ugly as f*ck.
So there's good news and bad news. Good news is that I've found a way to properly apply the tempered glass even on the margins. Bad news is that you need some tools you won't find in the original package, namely a VISE (yes, that thing on the WinZIP icon) and SILICONE OIL or VASELINE (both have to be perfectly clear with absolutely no colour and make sure they don't change colour in time).
I only did this once with a Nillkin tempered glass for my ze520kl but it should work for any curved screen.
Ready ? Ok so go ahead and perform the steps as indicated on the original packaging (clean the screen with the alcohol wipe, dry the screen with the dry wipe, dedust the screen with the anti-static sticker, perfectly align the screen protector and apply it). Obviously it won't stick to the margins so here comes the hard part.
This is going to take a lot of patience but not much effort. The key to sticking to the margins is a lot of constant pressure and if that fails this is where the silicone oil comes in handy to fill the gap between the screen and screen protector.
So this is what I did to get a perfectly applied tempered glass on my zenfone 3.
-First I tried to fill the gap on the margins with a drop of silicon oil and then I applied pressure on the margin intermittently with my thumb to help the silicon oil to get inside the gap easier then I wiped the excess. The purpose of the silicone oil is to create a clear visco-elastic medium, a bridge if you like, for the light to travel between the screen and the screen protector without changing path (without too much refraction). Problem is that it can't fill the whole void and you still get a bit of halo here and there as there is still some air trapped within the adhesive.
-This is the part where the vise comes in handy. I strongly recommend you use a vise with rubber protection on the jaws (or whatever they're called). You could in theory do this with your thumbs but it is very hard and tiring and you can't apply constant pressure for a long time.
So I fitted a margin of the screen in the vise and tightened the jaws hardly enough to forcefully compress the adhesive and remove the air bubbles trapped inside but soft enough not to actually crack or damage the touchscreen. Then I left it in there for about 1 hour on each of the 4 sides. If there was still some air trapped in the adhesive I would apply some pressure with my thumb to stir it a little and then I put it back in the vise and leave it for a while longer until there would be no air left.
After 4-5 hours I got a perfectly applied screen protector on my zenfone 3 with no halo effect on the margins.
Since I've never done this before I have no idea how long this will last and if the problem will ever occur again. But if it does then all you need to do is just apply some more silicon oil periodically and you're done. There won't be the need for the vise anymore.
Good luck and I hope this bit of information will help someone in the long run to develop and perfect the method. I doubt the average user has a vise installed on his/her desk so this tutorial is mostly intended for the more savvy people. Don't blame me if it doesn't work for you or if you damaged your phone.
Also, I suspect that on various models of smartphones there won't be the need for the silicone oil and all you need is just some good constant pressure.
