[Q] Lag not IO Related - Nexus 7 Q&A, Help & Troubleshooting

I just purchased an 8 Gig C70 Nexus 7, I have had a few cases of the device really lagging between home screens and touch interaction. A reboot fixes it. My write speeds are around 6 Meg. Has anyone else experienced this? It has happened right out of the box still at 4.1 and also after the 4.1.1 update. I am completely stock not rooted. So far it has only happened 3 times and I am thinking it may be app related I will try to keep a better eye on what I am doing next time it happens. I have over 5 Gig still of free space and have only loaded a hand full of games and apps. When it's working the way it should I really am loving this tablet compared to my larger ASUS TF101. Thanks.

Anyone Upgrading? To A510,A700,Nexus 7

anyone going to switch to the newer acer devices? or the nexus 7? because tegra 3 is out and it seems very good, also might get the nexus although it would be missing external sd slot but that can be fixed if you root it, and the newer acer's seem to get hot but are getting fixed with software updates, what do you guys think? is it worth to upgrade to tegra 3? or wait for tegra 4 in 2013?

Already bought a 701. Still keeping the 501 though.
The hot processor is due to it being a high performance tablet. There's no way yet around this, but hopefully some newer updates will lower the temp down a little.
It all depends on 2 things.
a. Do you want it?
b. Do you have the cash?
If you answer yes to both, or yes to one, but unsure of the other, then go out and get it.

Well, the interface is ok. ICS. I really didn't get a good chance to play around, as it.... ahem.... bricked. (no comment, but you know me, testing a tweaked kernel. Seems the recovery author screwed the pooch on the recovery. Not only wasn;t tested because he doesn't own a 70x, but was based on the 510 recovery, which the author of course later found it, it bricks the tab when you restore Lesson learned. Well, should get it back hopefully in a week. About time I bricked a tab
I wrote an initial review in my rom thread.
Basically, the only complaint I had, was 2. Hot processor (supposedly an update has either been released, or promised by acer), and the screen sensitivity is in my opinion, not as sensitive as the 50x. Sometimes had to press a little harder. But I think both can be fixed with an update. It's a first release after all.
Overall, a good upgrade I think. But if you can get the 51x at a better price, and can sacrifice the HD display, you might be better off. But that display...... Daaaaaaamnnnnn.
EDIT. On a sidenote, the TF Prime also has Tegra3, and it also runs warmer than normal under load. And they don't have an HD Display. But if you OC the TF Prime, to 1.6 and give it a load, it runs hot. Mine, out of the box, was 1.4. Strange. But it never rebooted after 30-40 min of Shadowgun. But was pretty hot. 90c maybe. I would probably advise 30-40 min of solid HD game playing, then let it cool. It cools down really quick when you let it rest for a couple minutes.
MD
You know, being a techie with means, in a way I am very much tempted by Tegra 3s and all the new hardware, but I stop and ask myself, why? I don't play games on my 500, and I run reflexxx, so it does everything I want it too, and smoothly.
I think for me, personally, it's less of a question of whether I have the money or the desire, and more of do I have an actual need? I mean, Chrome, Perfect Viewer, and Moon+ don't exactly need much horse power. Perhaps if I sat down with a Tegra 3 workhorse I'd think differently, but short of putting on a T3 game and saying "oooh" for five minutes, I can't see any real benefit beyond a slightly better battery life.

The on off switch on my A500 totally broke off the board so I am out of luck there. My wife's still works for her though. I'll probably go for the Nexus but I'm not happy with no SD card slot

I think that I'll hold out until the holidays before I even think about a new tablet. By then it should be well known which ones have good dev support, lots of ROMs, etc.

Welcome back Erica. Good to see you. It's been a while.
I also saw that there might a kindle fire 2 in a ten inch version on Aug. 6th and the galaxy note 10.1 inch so I might wait till then and see If they start making nexus 7 in 32gb but I doubt it

I bought my a500 last December when Target had them on a fire sale. I'll probably do something similar this coming holiday season. Truth be told, I'm incredibly satisfied with my Iconia, but I'm always interested in the next best thing, and Tegra 3 has the right mix of performance and price for my income.
I won't get a Nexus 7, however. No SDcard, no HDMI, and no USB host are all deal breakers for me. The Iconia has spoiled me in this regard.
I'm thinking about getting myself a Nexus 7 to go alongside my a500. You can never have too much tech.
I have had a a500 since about July 2011. I really like it and with ICS it got even better. I replaced my rooted Nook Color with it but for reading I find the a500 to be too heavy so I picked up a Nexus 7 last week. LOVE it! Super light and great for reading on and I haven't touched my a500 since. I do really like JB and the smoothness of Tegra 3 compared to the a500. I think I will still prefer the 10 in tablet for web browsing but for $199 the N7 just can't be beat. Can't believe I was recommending the Kindle fire to friends just a month ago.
Used a nexus 7 for a few days, passed it along to my parents. No hdmi, no card slot, that's a dealbreaker. I'm waiting to see an A700 in person, but the Nexus 7 will be a tough act to follow. I'm hoping Google will follow up with a Nexus 10 that fills in the gaps of the Nexus 7.
hopped on teh nexus 7, I have been wanting a smaller tablet, plus my step dad now has the a500 which helps while he is waiting for kemo, for some reason it takes like hours just to get into treament
No more tegra for me. Im waiting for an cheapass tab with an high quality screen and a nice resolution cause thats really the only thing I need and in my eyes mather these days. Since all cpus are strong enough for most of the tasks. For example; my Desire Z with an 800 mhz cpu can play all the latest games like gta, maxpayne, dead trigger just fine. It even runs xbmc with navi-x totally smooth. I can even say it handles the most important tasks like browsing and playing video much beter than my dual core crappy tablet, especiely video decoding. And since xda officially gave Nvidia the middlefinger I do the same.
EDIT: The desire even runs dead trigger with tegra 3 graphics tottaly smooth...
After the A501 I will never buy another Acer product and I recommend anybody that asks my opinion on the matter to stay away also..
I just picked up a Nexus 7 last week. Got tired of being behind for AOSP ROMs. Didn't realize about the lack of USB hosting or I might not have bought it. Having a slight screen issue so it might go back to Staples.

Nexus 7 to Note 8.0. Thoughts after switching...

I like to consider myself objective when it comes to reviewing electronics. I am a fan of the Nexus line because I like the immediate updates, and I constantly flash new ROMS. I still own my Nexus 4 and have been extremely happy with it. As far as the differences between the N7 and the Note 8.0 they are almost two completely different devices. At work I use my tablet for looking up manuals (PDFs), navigating while flying and as a daily planner. At home I use it to surf the web, read the news and watch Netflix. I DO use the s-pen on a daily basis. I am not a big gamer on my tablet. Here are my thoughts between the two devices.
Screen:
The screen on the Note 8.0 is unique in that the specs are lower than the Nexus 7, but it performs outstanding. It is noticeably wider than the N7. It is much easier to view web pages and also use as a GPS with my flight maps. I do think you can notice the pixels slightly more when reading text but not even close to the extent of that on the Note 10.1 (I have used one a few times). I thought the 10.1 was completely unacceptable. It is almost like putting a matte screen protector on a Nexus 7, it adds a slight pixelation. The odd part is the despite the decrease in pixels from the N7, movies are so much clearer on the Note 8.0. Samsung does a fantastic job rendering videos and HD content looks fantastic. I am sure the colors make a difference, but content is fluid, fast, bright and crystal clear.
Color:
Colors are outstanding on the Note 8.0 compared to any other device I have used. Overall brightness is higher and the colors pop (without the burn in possibility of a Super Amoled Plus). The screens runs on the cooler side with whites, but that is how I prefer them. The tablet comes with a "reading mode" that makes whites more on the warm side. Samsung states that this is to reduce the strain on your eyes and it truly helps. I think this mode allowed Samsung to keep whites on the cooler side without risking people not buying the tablet for reading books.
Sound:
Sound on the note 8.0 as well as the Nexus 7 could be better. It is fine for YouTube however music Lacks dynamic range. This is fairly standard across the mid-sized tablet line-up. The Note 8.0 speakers are slightly louder and clearer than the nexus 7. One key difference is the Location of the speakers. The Nexus 7 speakers face aft where as the Note 8.0 faces the side. This makes the Note 8.0's speakers better for movies and YouTube. I have not really noticed an issue with the lack of sterio speakers. In execution the sound just appears to come from the location of the screen and not one side or the other.
Battery:
I get 7-8 hours on screen time consistently. It is slightly less than my Nexus 7 with on screen time. The Note 8.0 is much better than the Nexus 7 with battery drain with the screen off though. I average a drain only 1% per hour with the screen off.
Apps:
I use the ANote HD application for my daily planning. It has some flaws, but helps me stay organized. What I do not like is that Samsung packs a ton of additional apps that can not be uninstalled by the owner. This includes the app store, peel etc. All they do it take up space. Additionally you can not transfer apps to the SD card at this time. The S4 just got an update allowing it and I hope Samsung will update the Note 8.0 to allow this.
Camera:
I did not think I would use a camera on a tablet, but I have found a purpose for the camera on the Note 8.0. I use an application called "camscanner" and this allows me to take pictures of test flight cards, memorandums, business cards and organize them as PDFs. I can also attached the scanned pics into my ANote HD app. It works extremely well.
Conclusion:
The one thing I really miss is NFC. I used it between my Nexus 4 and Nexus 7 to share pictures when WIFI was not available. I loved my Nexus 7 and only talked myself into getting rid of it for the s-pen, ANote HD app, and the price of $325 plus $25 Play Credit didn't hurt. After getting the tablet (my first Samsung product) I can say that I have NEVER liked an electronic this much. It works so well I did not even find the need to unlock it, which is good because development is still a little slow. If you think you will use the s-pen and can get a good deal like I did I would switch. I also decided to pull the trigger before the new Nexus 7 dropped so that I could still sell mine for a decent price. I Sold it for $250 with my Otterbox case so not bad.
Hopes this helps anyone considering the two tablets. Don't forget to hit the "thanks" button if it did. Please feel free to ask specific questions.
I like my note as well, got it for 4 days. Although it does freeze randomly (while trying to text, the screen is unresponsive) but its really not that bad. I got it from best buy and they priced match with staples($350). I have about 10 days now to return and I'm hoping to hear more info on the new nexus 7. I plan on switching because I think 7 is a better size but this note is pretty nice (with the s_pen of course). I've disabled certain system apps so hopefully its a bit faster. I am running stock, and after my 15 days are up, I'm going to root ;P so they better release info on that new nexus!

Thanks!
I found your article extremely helpful in making a final decision on my new device. I came from a pre-owned Nook Tablet that I rooted sometime last year, so I can't say my standards were very high to begin with, but I had my heart set on a brand new device. This was to be the 1st brand new tablet I've ever owned, so I was torn between affordability & performance. Alas, thanks to your experience, I believe I've made the right choice. I couldn't help rooting & loading custom recovery the same day I received my Note 8.0 though. After removing the phone apk, I found battery life in sleep state to be amazing! Left my tablet alone for an 11 hour work day, and it was still at the same level as when I had left it (86% btw). Sorry for getting kinda "rambly" there, I did mean this to be a short thank you for sharing your experience. Hope someone else out there comes by your post and makes the right, albeit expensive, decision.

Same problem in n5100 stock firmware, seems a samsung bug in all note 8 models. Solved with n51XX Civato's kernels and custom rom. No more random freezes. now is the best tablet

I really appreciated your post because you discuss real world use of the devices and not whether they are made of "cheap plastic" have technical specs 2 ppi difference, etc. Thanks for a really useful review.

I use my Nexus 7 now as my Kindle Reader. I've got one of the older Kindles and the screen just seems too dull for me. The 8 has replaced the N7 and it is a worthy upgrade.

Thanks for this useful post. I am really attached to the Nexus 7 so replacing it with another tablet was always going to be hard. I had the option of a mobile phone upgrade with a 'free' Note 8.0 and now I do feel confident that this will be an ideal replacement.
I was slightly disappointed that you didn't rate the sound from the speakers. The Nexus has pretty poor audio output, I was hoping the Note was going to be much better.

I can confirm on my 5110 that Civato's kernel solved the intermittent pause issue. Still running stock ROM.

Not to quote myself, but it is important to note that from what I've read so far, if you go with *anything* custom (root, ROM, kernel, recovery) , Allshare *will not work*. I found out the hard way so I can't use my Miracast adapter with it.

Thanks for this, I have been looking at the Note 8 for a while now.
I had the Nexus 10, but the clock kept slipping so I sent it back to Google.
Had the Nexus 7, but I found the screen to thin for reading on.
Might give this a go now.
Thanks :cyclops:
wow nice, have u rooted ur note 8?

Not a dumb question at all. It comes with 4.1.2 but a leaked 4.2.2 package is now available, which is what I'm running (rooted) with no trouble.
As a quick update I have noticed that using the power saving feature significantly increases the screen in time. In power save I average 7-8 hours on screen time surfing the web. Turning off power save mode decreases the battery by about an hour.

What settings were you using in power saving mode. Did you only have screen power saving on only? if so, thats impressive. if you had cpu power saving on as well, then i would expect to see a good 10% additional battery life under continual use as the CPU is limited to 1100MHz rather than the usual 1600MHz.
Still scouring for news on n7 refresh. Although the main thing why I like to get this note 8 is the s pen future. Any other devices offering similar feautures ? Or as add one? Review on note 8 with s pen is very few and even after trying many-many time at the shop I am not convinced that this is the best solution

When I use power save mode on I almost always have all 3 settings selected. I have not noticed a decrease in performance. The only time I run with the full processor is when I am multitasking or using photo shop and trying to check XDA etc. I am also running stock.
I, too, switched from a Nexus 7 to a Note 8.0. I have the AT&T model with LTE (got the promotion price at $199 on contract). I can honestly say that, other than the immediate updates that you get with a Google-built ROM on a Nexus, I don't miss the N7 at all. The Note 8.0 is a definite upgrade in terms of hardware. It's fast, Touchwiz is easily the best Android skin (and there are a number of things I'd love to see Google implement into the stock UI), and I love having LTE on the tablet.
Overall I'm a happy camper.

Im pretty much the same. I only take it off power saving if i know im playing high requirement games (real racing, horn, modern combat etc etc).
I would turn it off for drawing apps as well as i imagine that once you have built up a few layers and have used a few different pens it would start to takes its toll and id like my lines to be drawn as fast as possible with no lag. saying that, ive not had a chance to draw all month as ive been camping, had my girlfriends mums birhtday, my girlfriends birthday and this weekend, my mums birthday and have been out pretty much every day.

Signs of Aging?

I'm considering different tablets and I'm wondering how well the nexus 10 is aging. How's the processor compare to more modern devices? Is it still smooth running KK ROMs? What can it be OCed to? Thanks for any input/advice you could give a potential buyer this late in the device's life cycle.
Sent from my Slim Nexus 5 with smoothness by Faux.
Hi,
I believe Nexus 10 is still not showing big signs of aging, I mean, the screen is still great, the processor still runs fine everything I need (games like Modern Combat 4, Ravensword Shadowlands, GTA SA [max graphics settings], Cytus and Deemo run perfectly fine with no lag at all!).
The only thing that most people complain and they are right is that due to the huge screen resolution Google allocated 1GB RAM to graphics, which makes it only 1GB RAM. And that means that some apps will close just after you exit them and open another (happens a lot with Chrome tabs too, when I'm with 7-8 tabs open, one or another will need to reload).
I don't know about others tablets yet, I didn't have the chance to check how they perform against Nexus 10. Just don't let benchmark scores scare you, just because one device performs 40k points that doesn't mean it is the best thing ever. Sometimes my Nexus 10 looked more fluid (specially when watching videos) than my S4, while my S4 performed 28-29k points, Nexus performed 24k.
Also there was a video comparing Nexus 10 to Galaxy Note 10.1 2014, due to crappy Samsung software Nexus opened apps faster and was more fluid. The screen had some differences too, Note colors looked more vivid, but that's more of a personal thing.
And for KitKat ROMs, as KK is official it's running perfectly fine. I'm on CM11 after formatting and it was the best thing I ever done to my device. It's blazing fast and does everything I need. And I have no ideas about OC, personally I never used as there was no need.
Just to finish now, Nexus 10 is on the end of Google's 18 month support policy, so if you want to get a Nexus I'd wait for next Nexus 10, as it will have again support. Personally I think that 18 month is now a ridiculous thing, as 2012 Nexis still run perfectly fine, and they can support easily a next update.

[Q] Stylus Lag on Nexus 10

Hi,
I'm trying to use DioNote and similar handwriting apps on my Nexus 10, but am finding that the stylus tracking is so laggy that my writing looks awful. The app works great on my LG G3, however, but that device is a bit too small for most of my note taking.
I've tried several ROMs on the Nexus 10 to eliminate the stylus lag, but so far none have had any impact.
Does anyone know how the lag can be significantly reduced?
Thanks,
Jeff

Does anyone know how the lag can be significantly reduced? I have one of this basic pen. Ones and it registers just like my finger. But honestly if you want hand note taking get yourselfa note 10.1 2014. Theyre on sale right now and no stylus can compare to the s pen right now

What stylus are you using?
Sent from my VS980 4G
Unfortunately, I don't believe that the problem is with the stylus. I've tried the Musemee Notier V2, AmPen, ButterFox and others. Regardless of the stylus used, the screen lags by about 0.25 seconds or so, making it difficult to write quickly, especially for characters that require a more than one stroke.
The problem is almost surely the firmware / digitizer on the Nexus 10. I am hopeful that this gets better with 5.0, as I'd rather not purchase a new device.
Thanks,
Jeff
I had the same problem with my nexus 10 on kitkat, today I flashed the factory image of lollipop and the lag is definitely gone at least with InNote

Yep, I flashed 5.0 stock today as well. Although my favorite, DioNote is not yet working with 5.0, the lag is significantly reduced to the point that the Note 10.1 (2014) is no longer on my "must have" list. By the way, 2 things are killer functionalities for DioNote: (1) Sync with Evernote (2) full text search on handwriting. Can't wait for them to fix it to work with 5.0.

screen still sluggish/laggy?

So I'm thinking about either getting a Samsung Nexus or the Nexus 4. According to this video and one can even see it, the screen is somewhat unresponsive. Does this issue persist with newer Android versions? At the beginning he even says one has to type moderately to not skip letters.
httqs://youtube.com/watch?v=-SCJG9JMnlY&t=11m55s Nexus 4 vs Galaxy Nexus
The nexus 4 is still a good device I use mine as a backup but I have no doubt that I could use it as a main phone,stay far away from the gnex it was a good device in its day its just to slow even for basic tasks I had one it eventually died
The unresponsive screen was fixed in an update I think. I never have to press a letter twice when writing messages, im on kitkat.
