[Closed] Nexus 7 2012 owners - this might help

Did it and mine is still laggy.

5.0.2 is rolling out. My mate got the OTA update and it seems to have sorted his Nexus out.

I've held back with the lollipop upgrade until this week. I've installed 5.0.2 as I thought it would be sorted by now.
It's not. It's slow and Chrome keeps crashing.
Cleared the cache but no better!

Mine is pretty much unusable now. I also changed to a new battery but still, it barely charges. Takes about 6.5 hours for a full charge which won't last long at all.

It's laggy, it constantly crashes on Dolphin browser and I got sick of it.

Day before yesterday I gave up and went to PC World where I picked up an Asus Memo Pad 8 for £139.99 with £50 trade in on your old tablet, which makes it £90...

The new one works really well, no lag. Resolution is not quite as good as the Nexus in close up photos but more than adequate for most tableting...
Bigger screen is nice too for watchin' telly...

Upgraded to 5.0.2 here on my 2012. Lag is no worse than 4.4.2. Removing Facebook and all publications from the google newstand app has improved things. I can only assume these these do a lot of background work....

5.0.2 fixed mine.

I did the factory reset as recommended on here. It now works fine.
Tried the cache first and it made no difference.

After a cache partition wipe and hard factory reset I think - I hope - that it's finally fixed.

Asda are selling off the 2013 models for £50 if you can find a store with stock.

I sold mine and bought a Hudl 🙂

Just an update on this.

The initial Lollipop killed my Nexus 7, utterly unusable. The 5.0.2 update made it a lot better, I thought it was fixed at first but it was still problematic. Sometimes it was fine, sometimes it was terrible. In particular, it was lagging like a plumber for ages if I'd had to reboot it. Cache cleaning made no difference.

But, after a lot of cocking about and trial and error, I believe I've isolated the cause, on mine at least.

And it's... *drumroll*... the Facebook app. Uninstall it and it's slicker than greased squirrel shit, put it back on and it all goes to custard again.

Try it, let us know how you get on?

After the 5.0.2 update and the factory restore mine is pretty much back to its old self. No facebook or yahoo apps though.

Mine died when I did the latest update. Phoned google, they said do a factory reset, that seemed to work for a while, then died again. Phoned Asus, they told me to clear the cache, that's improved it, but still not as good as originally.
Off to get rid of FB now 🙂

Ta cougar!

5.0.2 here for a couple of weeks it really hasn't sorted things out, periodically it will run OK. Then lag like a bastard, power off, clear cache, still runs slow, but later it might speed up a bit... Getting close to just doing a factory reset now...

I've done a factory reset on mine and it's still paying up.
Just uninstalled Facebook, see if that improves it.

Ooooh, FB unistalled, I shall see if that improves things...

Battery performance likely to improve?

Mine's the same, as is my other halfs - was absolutely faultless before the upgrade - went straight to 5.0.2 and totally trashed it. up to a minute for keyboard to pop up, any browser crashes after 5 minutes and if any flash is involved it locks up. Useless paperweight now. What I find odd is that Google seem to be completely pretending it isn't happening.

My 2012 Nexus 7 was starting to get a bit laggy running on kit kat. I resisted the OTA update to 5.0.2 for a while but after clearing the cache partition a few times and carrying out a factory reset I decided to bite the bullet and install 5.0.2.

Initial impressions were pretty good and it was generally running a bit better than on kit kat, although at times it does struggle, with say several tabs in Chrome. I shall try uninstalling the Facebook app though to see if that makes any difference.

I also noticed that my WiFi setting to switch off when device is in sleep had reset to the default always on mode. I guess this happened during the factory reset, so I have reverted back and noticed a marked improvement in battery life.

Switched to using firefox instead of chrome and it is much better especially if you install plugins that must not be named

my daughter's is really struggling at the moment - tried clearing the cache and its not much better, so thinking of doing a factory reset...

However...

She has the 'paid for' version of Minecraft, will she have to buy it again, or will it automatically come down again from the store?

Will she lose her stuff from the game or can you export/save it somehow?

EDIT: just found this http://www.howtogeek.com/202591/how-to-backup-your-minecraft-worlds-mods-and-more/ which has some instructions on how to back up Android version of Minecraft

thanks

5.0.2 made no improvement, bloody awful lag on chrome, esp when it was trying to sync with email. Took the plunge and did a factory reset, all apps were reinstalled OK and photos etc were backed up already. Much less hassle than I thought and now runs as it was before lollipop-gate. Had previously removed FB app because I thought it was dragging it down.

Edit - no paid-for apps/ games on mine.

Uninstalled FB, performance still poor.
Have just now done a factory reset, cache cleared, and only installed a few apps (not FB).
So far so good!

I found firefox caused crashes on both my Samsung phone and my tablet - binned it.

Well I uninstalled Facebook from mine last night and it has made a big difference ,so cheers for that ?.
I hope it improves the charging time too as it sometimes takes 12 hrs or more!

Unistalled FB, and some other apps, no discernable improvement TBH... think I'll make sure anything useful is backed up and do a factory reset tonight shame really...

4 days in after reset and cache-clearing and NOT installing FB app, and all appears to be good! Can still use FB on the browser so no problem there 🙂

That was a factory reset paladin?

What version of android has it taken you back to? kitkat or earlier?

Didn't get round to doing it last night, battery was on about 6% and not charging so I left it... but I need to sort the bastard thing out now...

Yep.

Still on 5.0.2 , I think its just user data and files and settings which get wiped, but OS stays same.

[url= http://www.gottabemobile.com/2014/12/29/android-5-0-2-problems-fixes/ ]this is worth a read too[/url]

Finally did the Factory reset last night, took the opportunity to cull a few more apps too, 5.0.2 now seems to be running well and battery performance is back to acceptable levels.

Does seem to be the only way, might just do a periodic reset from here on regardless, 2.5 years of under maintenance does have an impact...

Binned mine, got a recon hudl off eBay for £50, very happy!

Another update on this.

Android 5.1 seems to be available OTA.

I downloaded last it night for my Nexus 7 (2012 version) and so far so good. Seems much slicker and faster than when it was running 5.0.2 so theres is hope for anyone that persevered with their 2012 N7.

Did people ever get them working again. I use facebook so want to keep it.

5.1 didn't seem to do much. I'm thinking of going back to [s]lollipop[/s] whatever it was called v4 if it is possible. Tablet is lagging so much that I am using the PC even after boot up it can be quicker than faffing with the tablet.

mine works perfectly these days, and has done for a good while. but without the FB app. i never bothered reinstalling it, and don't miss it on the tablet.

Mine works, though can be laggy on occasions, even after the latest 5.1 uodate. I read there's a 5.1.1 update on the way. Whether or not we get it, and if if finally fixes what they broke; who can say?

If your '12 is still happy on JB or KK then my advice to you is not to update until this mess is finally sorted.

So mine never got better and I was looking at buying a new one. Before I spent any money I though I'd have a play rooting it and installing a different ROM.

Eventually got round to installing Cyanogenmod and it seems to have perked up considerably. Definitely useable in a way it wasn't before. Well worth it if you are still struggling.

There are guides on how to install it if you google. Pretty straight forward. I don't know much about Android and rooting things but I managed just watching you tube videos and googling a few bits.

Mine was grinding to a halt so I tried rooting and TRIMing the file system (after some googling of the issues and solutions). Process of rooting included a factory reset, which might also have helped. Still running stock 5.1.1, but running much much better than before. I have a usable tablet again. Still haven't loaded all my apps back on yet, that might slow it down again, so I'm being selective in what is loaded back on.

I sold mike on Ebay for £40 and bought a Hudl 🙂 and the battery on it is now done, so waiting for a new ebay battery 🙁

keen on a new tablet, but given that they only seen to last 2 yrs max, I wont be spending over £150 on one.

For me it was the latest update (5.1.1 IIRC), the removal of the Facebook app and clearing of caches which finally made it usable again. It's still a little laggy and takes an eon to boot, but it's not the paperweight it was.

TBH, out of that lot it was FB that made the biggest difference.

I never even had FB installed on mine. 5.1.1 and frequent cache clearing and it was still a frustratingly slow PoS till I rooted and TRIMed it.

Mine is on KitKat still..........resisted the change to lollipop as several Forums highlighted problems if you did...especially running a aviation GPS app which is the primary use . Boot up time is considerably slower that it used to be.

Bit academic now as it got dropped and screen now cracked 😳

What to replace it with ?? a 2013 version (still avail new ) or something else ? the nexus 9 I think is too large for flying , maybe the LG Pad

There's a Nexus 8 imminent I think.

Anything BUT a Nexus device given previous experiences.

Well mine is trundling along fine except... The Micro USB port has started to go a bit baggy so charging can be hit or miss... I've 'adjusted' it (read poked it around) to tighten it up which has worked so far. When it gets beyond this, I expect I'll be looking at one of the usb kits on evilBay.

Anyone got a link to the root and trim process? And does it wipe all your data and make all that Google auto sync type stuff impossible?

I refuse to give up on my Nexus!

This is the page I was following to speed up mine

http://www.howtogeek.com/164106/why-is-my-nexus-7-so-slow-8-ways-to-speed-it-up-again/

It included the TRIM process, but I couldn't get LagFix to work and ForeverGone seems to have forever gone from the marketplace, so I used Trimmer ( https://play.google.com/store/apps/details?id=com.fifthelement.trimmer&hl=en_GB). They all perfrom the same fstrim command under the covers.

The first page above links to the follwoing process for rooting which is what I followed, prior to TRIMing.

http://www.howtogeek.com/120482/how-to-root-the-nexus-7-galaxy-nexus-or-nexus-s/

The link for the rooting tool kit download on that page is dead, but it can be downloaded from http://www.wugfresh.com/nrt/

I'm no expert, this was my first attempt an rooting and I just followed the links and the pop-up help in the tool kit. Good luck and don't blame me if you brick it.

Yes it does wipe all your data at the unlocking step before rooting as a factory reset is done at this point. The process recommends you to do a back up and the tool kit can do that first. When I logged back in after the reset I deliberately didn't sign in with my google account to avoid it bring all my apps etc back, wanted to start with a clean slate. It is mostly just used for browsing anyway.
