Nexus 7 2012 feeling slow these days.

[Eug]

My Nexus 7 2012 seems to be lagging a lot these days. I figured with the addition of TRIM a while back, and the more streamlined and supposedly memory efficient kit kat, it should feel faster, but if anything it feels slower than before. Occasionally there will be lags of a couple of seconds here and there. Not quite as bad as my 4.1 dual-core RAZR HD, but still noticeable.

Has anyone noticed anything similar? It is not due to lack of storage, since I currently have over 11 GB free on this 16 GB model. Are the Google apps like Chrome just getting bigger? The 2012 Nexus 7 only has 1 GB RAM.

Mine was getting a little laggy under 4.3, but I did have all the storage almost entirely full. I gave it a factory reset just prior to it getting the KitKat ota. Still has the occasional stutter, and no its no where near as fast as my Note 8. But I wouldn't call it unusable.

There's some variations in the NAND speeds on the N7 2012, making some devices degrade quicker.

Some people said turning off wifi battery optimization may help so I've done that for the time being. I will also try clearing caches again but I've already done that before. I hope I don't have to do a factory reset.

How much free space do you have? Anything less than 3 GB and performance falls off a cliff. At least that is what happened to mine and my friends awhile back.

My 2013 N7 and S4 do that too sometimes, like once a day. It's Android.

My N7 (2012) got slower over time even with TRIM. I suppose the NAND was not up to the task as it gets filled. I restored the stock image before selling it, and it felt as snappy as it was on day one. Not sure who's more responsible, the OS or the NAND. My Nexus 4 has held up fine to date but there isn't much data in there. (It's a $200 8GB version)

11 GB free.

It happens several times a day now and it is noticeably worse than it was several months ago when I only had around 3-5 GB free.

I'm thinking I may just have to factory reset it even though I have 11 GB free. It is just a PITA though since there is no true native restore function. Mind you if I did a complete restore I'd possibly run into the same problem so maybe that's a moot point.

Ok, that is not normal.

Do you have root access so you can clear the Dalvik Cache?

And don't forget Tegra 3's 32-bit single channel memory which maxes out at 6.4 GB/s in theory. In practice the bandwidth is probably half that. The more stuff is running in the background, the worse things get. Run task manager or something of the sort and see how many things are vying for resources.

Not rooted.

Not rooted. I had even more problems (stability, battery life) when I was rooted, due to a few third party apps that require root.

OK good idea. In the meantime I've been just killing apps manually and/or rebooting periodically.
