[Nexus 7 Q&A, Help & Troubleshooting] Icarus2012:
Hi there. I've got a need to convert about 50 x Nexus 7 units to use the Pixel Qi screen. The application is in an outdoor industry requiring sunlight readability on a portable device.

ttp://w w w.pixelqi.c om

I don't know if it's possible yet, but there's two major issues to overcome -

1. Driver support for the 7" 1024x600 panel,

2. Hardware compatibility for the Pixel Qi LVDS LCD.

On the first item, Pixel Qi say something to the effect that the LCD is 'plug & play'. While I don't doubt that for a Windows based system, does Android have an archive of drivers for true 'plug & play'?

On the second item, I can't find any specs on the hardware or LCD connector type for the Nexus 7. The teardown sites simply have images of the LCD. Can anyone offer what sort of industry spec the Nexus 7 uses?

Thanks in advance.
[Nexus 7 Q&A, Help & Troubleshooting] andjohn:
#1: This won't work. LVDS is the port on the Pixel Qi screens, and I doubt the Nexus 7 has a full LVDS port inside.

#2: LVDS is a 'standard' where the transmission of screen data is standard but the ports are not. It makes it difficult to work with. That's why you can have screens that should work with all laptops but don't.

#3: 'Drivers' don't exist for screens. The screen's firmware sends it's properties down the LVDS connection, the Pixel Qi simply has the transreflective setting as 'backlight off'. There is no drivers to find. The port is your big problem.

#4: No touchscreen. This won't be fixed.

#5: Pretty sure, if you don't already produce electronics from the factory you work at or own, you can't get it done.

Solution #1:

A Crappy Android laptop without touchscreen will probably have one of the standard LVDS ports inside, this one would be super easy to do. They are cheap, so testing isn't hard.
[Nexus 7 Q&A, Help & Troubleshooting] Icarus2012:
Thanks for the extensive information. The choice of the Nexus 7 as a starting point is just because it's very cost-effective on it's own. Start adding ~$200 for a Pixel Qi screen, and it's still a reasonable proposition.

The form factor requirements of the application (an aircraft cockpit) demand a small device of the 7" size.

Can anyone recommend a 7" Android tablet with an unbonded touchscreen that might suit the task?

[Nexus 7 Q&A, Help & Troubleshooting] chaddeus:
I think it would be awesome! I never see Pixel Qi in real life and not sure how good it is but it sounds awesome!! I wonder why its taking so long for mass adoption. Anything wrong with it? Cost too high?

Pixel QI on a Nexus 7 would be freaking awesome!
[Nexus 7 Q&A, Help & Troubleshooting] 339willow:
You might want to check out Sol Computing (or something like that). They've got tablets and netbooks with Pixel Qi screens. I think most of the other products applications for Pixel Qi are in specialized markets, like military applications that require sunlight readability and low power.

Finally, I suggest you give Pixel Qi a call or email (pixelqi.com) and see what they suggest. If you've got 50 units to convert into a Nexus 7, I'm sure they would be just as happy as you, to find a way for you (and others) to be able to do that.

As always, free advice being worth what you pay for it.

Optical solution

We have a solution for you, the optical solution. We can optically modify 50 Nexus 7 by adding different kinds of coating, to make it Sunlight Readable. Are you interested in this solution?
[Nexus 7 Q&A, Help & Troubleshooting] Wilks3y:
Lol.
[Nexus 7 Q&A, Help & Troubleshooting] Icarus2012:
Sure....but I'm fairly skeptical of screen treatments having tested many of them. The sun has a brightness of about 6500nits. The Nexus 7 has a brightness of about 350nits. Most of the problem is simply that difference.

Unless you've got some sort of novel technology (ie. a transflective type display like Pixel Qi ), I can't see it being up to the task using screen treatments alone.

Any further information is welcome...YouTube videos, actual demo in sunlight etc.

[Galaxy S III Q&A, Help & Troubleshooting] muhamadasim:
Hi,

I have 3 issues. Hope somebody can help:

1: Phone operates too slow. For example when I go to menu, app icons take around 5 seconds to appear. Similarly when I go to home screen it takes the same lag. So much delay that I could capture the screen short. You can see that weather clock and alarm widgets didn't appear. I cleared cache several times n restarts but it works fine for few mins n then again becomes laggy.

2: Keyboard disappears after typing few letters and sometimes it takes several secs to get it back. Reappearing delay is may be related to the above problem of slow response but why it disappears in first place.

3: Battery doesn't charge despite the whole night charging. Its happens not do often but really bugging me. I noticed that whenever I get missed notifications like calls or msgs it stops charging. Not sure why it's happening.

Looking forward to some help from experts. Please note that I feel these problems are occurring more after recent update. I'm using stock Rom of intl s3 version.

Thanks

Ok read It agaIn. Thanks. If thats the only solution, will wait for jellybean update that's just around the corner. I wondered if anything related to hardware or phone settings was to be blamed. But anyhow, thanks.
[Galaxy S III Q&A, Help & Troubleshooting] samydroid:
I am also on XXBLFB and facing no such issues. You should check if some app is not eating a lot of RAM.

Jelly Bean won't be available for this region anytime soon keeping in view the time it took S2 to receive ICS update here.
[Galaxy S III Q&A, Help & Troubleshooting] muhamadasim:
I suspect the same. my RAM doesn't go below 600mb even if I close all apps and clear ram from task manager. After restart, phone behaves well for an hour but then again becomes laggy. My S2 is much faster than this with lot more apps. This S3 is really disappointing me.
[Galaxy S III Q&A, Help & Troubleshooting] samydroid:
Try to find the culprit app. I have 100+ apps and set is still very very smooth.
[Galaxy S III Q&A, Help & Troubleshooting] muhamadasim:
That's the status when I just cleared cache.
[Galaxy S III Q&A, Help & Troubleshooting] samydroid:
my suggestion is to do a factory reset (after backing up your contacts, messages, notes etc). then download your apps again and note the behavior of phone after each app. You might find the culprit then. It doesn't seem like an issue with the update since I also updated mine. Also very less likely its gonna be hardware issue.
[Galaxy S III Q&A, Help & Troubleshooting] demlasjr:
Maybe the CPU is not working at its entire power. If the factory reset is not working, maybe you should go and replace the device, before it's too late. When you bought it ? If the phone have less than 30 days you should get an instant replace. Not sure that JB will help you, as the installation isn't like a "full format" of your phone

Hard reset: *2767*3855# (no warning message before formating, so type it when you're ready, also remove the sdcard if you don't want wiped too.)

Or *#*#7780#*#* - Factory data reset - Clears Google-account data, system and program settings and installed programs. system will not be deleted, and OEM programs, as well as My Documents (pictures, music, videos)
[Galaxy S III Q&A, Help & Troubleshooting] muhamadasim:
Thanks. Will get in touch with the vendor for replacement (though I'm sure he will not agree that easily) or else will do a complete reset. I'm really pissed off for spending this much for getting this device. Samsung is very serious in pushing their loyalists away!
[Galaxy S III Q&A, Help & Troubleshooting] demlasjr:
Sometimes, there can be some errors. You know, nobody's perfect and we are all humans. After one week after I bought my phone, I found that it have sort of scratch on the screen, but looked like inside of it. It could be seen only in high light. The vendor replaced it instantly. This one is perfect. Love it and is extremely fast and I have many apps on it. Good luck!
[Galaxy S III Q&A, Help & Troubleshooting] muhamadasim:
You're a lucky dude:). I did one thing. Uninstalled AVG antivirus. Will update if I see some improvement.
[Galaxy S III Q&A, Help & Troubleshooting] demlasjr:
Check in task manager, you should have an idea about how is going bad. Also change the antivirus for Avast. Avast is much better. However I recommend without antivirus. I just scan sometimes my phone with it or lookout but never leave the antivirus installed. Is just a waste of RAM memory.

If nothing works do a full backup with Kies and do the complete factory reset.

Most of the apps will be automatically reinstalled when you add back your Google account, but you need the backup for settings and saves.
[Galaxy S III Q&A, Help & Troubleshooting] muhamadasim:
Uninstalled several apps. Removed widgets from desktops. But still same issue. One thing I'm not able to figure out is why my RAM doesn't go below ~600mb despite killing every task n cleaning cache. I guest a factory reset and ROM installation is the only way out. Thanks guys for all the tips.
[Galaxy S III Q&A, Help & Troubleshooting] demlasjr:
Even with all the apps I have on my phone the RAM usage is around 580-640 (stupid SwiftKey using 45 mb most of time) and when I kill the apps I have 430 mb, slowly increasing til 530. Try reset, you have nothing to lose.

Hi everyone, i would like to know if somebody tried the Samsung C pen (for the S3) on the nexus 7? Or if you have a good stylus for the nexus 7
[Nexus 7 Accessories] khaytsus:
Samsung C = Wacom Stylus

Nexus 7 = Capacitive screen, no wacom digitizer.

Not gonna work. But any other capacitive pen will.
[Nexus 7 Accessories] ScottC:
Wrong. The S3 pen is just a more expensive capacitive pen, you may be confused with the Galaxy note.

FWIW; I just tried my original S3 pen and it DOES work perfectly on the N7 - which is interesting because it does NOT work on the Transformer Infinity or Gnex.
[Nexus 7 Accessories] msgnyc:
Like ScottC said C-Pen is a capacitive stylus.

S-Pen is a wacom stylus.

Having tried the C-Pen. Way to over priced for a capacitive stylus that only works on some capacitive screens.

The elago stylus is pretty good in my opinion

I'm just looking for something slim that will protect the Note against scratches while I wait for a better case. On the video it looks like magnets are used to lock the cover in closed position... I would have prefered an elastic band instead and not having the cover wrap around the edge to the back side.

Well well... we'll se what it's like when I get it.

PS. I've emailed Belkin asking them to make their fine Slim Folio Case for the Note 10.1 as well. A friend of mine has it for the iPad 2 and the case is awesome.

Ill shoot belkin an email. That case seems pretty nice I just don't care for the bezel being covered. I say that never owing a case for my tablets like that. How much did it sell for in the Ipad version
[Galaxy Note 10.1 Accessories] Tubgirl:
Well if you don't want the bezel to be covered (I do) then you can just go for the Belkin Cinema Case for the Galaxy Note 10.1. Good materials used and nice finish I think.

Here's a video review of it... http://www.youtube.com/watch?v=q_ymHTmbXGc

Personally however I prefer the bezel to be covered (even better protection).

So now we know that magnets really should be avoided on cases for the Note 10.1. As I wrote in an earlier post I would have preferred an elastic strap instead.
[Galaxy Note 10.1 Accessories] alien45:
Thanks for sharing!:highfive: I was kind of considering to buy this one but had the same confusion as the OP.
[Galaxy Note 10.1 Accessories] stuartv:
So, this seems to confirm that there is a magnet sensor around where the stylus slot is, and the tablet uses that to turn itself on. Odd that, in this video, it's turning on when the cover closes instead of when it opens.

Anyway, my Exact case has magnets to hold it closed, but they are in the very corners of the cover - ie. far away from the stylus holder. My Note definitely does not react to them at all. And I like the magnet closure WAY better than the elastic strap deal on the Belkin Tri-fold case that I started with.

Other posts on here have stated that the official Samsung notebook cover also has magnets in it. I'm just guessing that that means that the screen will turn on and off automatically when you open/close the Samsung cover. If so, then I definitely don't see how you can condemn the whole concept of magnets on a GN10 case.
[Galaxy Note 10.1 Accessories] mitchellvii:
Could you really upload your image. It is broken.

[Galaxy Note 10.1 Accessories] BarryH_GEG:
The OEM Book Cover uses magnets so it's not all magnets that are bad.

"The way the Book Case folds back and its lip magnetically attaches to the rear of the Galaxy Note 10.1 is a smart approach to creating a holder that positions the Note 10.1 at a comfortable typing angle."

[Galaxy Note 10.1 Accessories] stuartv:
I wish I had seen this InfoWorld article before I ordered my Book Cover. I just read this:

I will probably cancel my order for the book cover. If it doesn't automatically turn the screen on/off, then it doesn't seem any better FOR ME than my $13 Exact case, which actually covers/protects more of the tablet - and does have a magnetic closure for keeping the cover closed.
[Galaxy Note 10.1 Accessories] twospirits:
That is odd. so the magnet is at that bottom part of the cover and not the top?

[Galaxy Note 10.1 Accessories] rayandreas:

[Galaxy Note 10.1 Accessories] Tubgirl:
I got my Gimmick Five case today and I'm somewhat positively surprised. After watching the Youtube video I thought the case would be useless but it's not. No matter how hard I try I haven't been able to turn on the display the way the Youtube video shows. The case is compact and the two stand positions work as expected without any problems. Also the Note is easy to hold when the front cover is flipped over to the back side. In this position the extra flap (that's normally used to wrap around the Note to keep the front coves in place) is not disturbing at all. It nicely kept in a folded position thanks to the magnets.

Speaking of magnets... that's the only concern I have about this case. I just hope it doesn't affect the wacom s-pen in any way.

Conclusion... I'm glad I ordered the Gimmick Five case. It's slim and offer nice scratch protection of the Note. It feels much safer handling the Note with the cover attached compared with not having any cover at all.

I'm sure there will be nice alternatives down the road but for now I'm quite happy with the Gimmick Five case.

R.E. MY NIGHTMARE!

Well, I could'nt get the back cover to snap back on easily. After trying different prying techniques I finally had to remove the silver cover from around the back camera. Then take off the 3 little screws and follow from the top right all the way around popping the tabs. In the meanwhlie I'm putting little nicks everywhere because of the soft plastic on the cover. yes, I'm pissed. Anyway, I had to do this to put the tabs back in properly. So, the whole back cover has to come off to get the tabs in correctly. I hope you don't go through what I went through. If you have plastic wedgers it should be a little easier on your tab but in either way it's still a headache and a nightmare.
[Galaxy Note 10.1 Accessories] Tubgirl:
Guess now you really have to use the Gimmick Five case to hide those nicks ;)

Seriously... what you went through on a brand new device really sucks! There should be instructions warning that this can happen if the case isn't removed in a certain way. :banghead:

Nevertheless... once the case is installed it's really not that bad... very slim and easy to handle. I might change opinion when I try to remove it. :rolleyes:
