Android 5.0 - A not so sweet lollipop for Nexus 7 2012

I updated my nexus 7 2012 (grouper) using the factory images to android lollipop 5.0 LRX21P. It took 30 seconds to flash the image and then 15+ minutes to boot the device just to get to the home screen. Once the device was up and running, I noticed that just browsing through the apps installed in my tablet and going through the new settings made it hot. Also all that useless animation made every action that I performed sluggish. The whole tablet experience is ruined. I have seen the videos for nexus 9 where the Lollipop was performing well, but personally I feel that lollipop is too much focused on graphical effects that it can no longer be used smoothly in older devices.

If you are also using Nexus 7 grouper then please share your experience with Lollipop below.

Hi Viraniac,

Thanks for posting your issue in the forum. After reading your post, I noticed you mentioned your Nexus 7 is the 2012 (grouper model). Please verify that you used the "Factory Images "nakasi" for Nexus 7 (Wi-Fi)" version. Its possible you used the wrong factory image which is causing your problems.

I highly recommend you restore the previous Android version 4.4.4 and use the OTA update for Android 5.0 which it becomes available on your tablet. 

Regards,
JP

Hi john thanks for the reply. Yes i am using the nakasi image for nexus 7 2012. I modified the flash-all.sh file while updating to keep my existing data intact. I guess some of the application data was the cause of the heating issue as i am not getting the heating issue after doing a factory reset.
 
However, i do feel that the animations are making this device feels as sluggish to respond. It was much faster before than it is now.

Hi Viraniac,

Thanks for the updated information. I haven't had a chance to flash (I'm still waiting on the OTA) for my Nexus 7 2012 STE model. I'm curious to see if there's any noticeable slow down on the animation as you reported. 

While reviewing your post, I shared this issue with one of Google experts in my team. He had an excellent suggestion, try clearing your recovery cache partition. See the directions below:

Nexus 7} When the device turns off, press & hold the Volume Down button, and then press & hold the Power button simultaneously until the device turns on. You'll see the word "Start" with an arrow drawn around it.
Press the Volume Down button twice to highlight Recovery mode.
Press the Power button to start Recovery mode. You'll see an image of an Android robot with a red exclamation mark and the words "No command."
While holding down the Power button, press the Volume Up button.
Use the volume buttons to scroll to "wipe cache partition" then press the Power button to select it.
When the cache is cleared, press the Power button on "reboot system now."

If you already haven't checked, make sure you have sufficient available storage space. If you're running out of internal storage, this can affect your overall system performance.

Let me know if my suggestions were helpful.

I also have lots of problems since the update to lolypop. Some to mention are slow boot, facebook closes, browser slow and freezing, lots of apps not responding, slow start and often non start of apps, etc.
I have cleared the cache using the procedure described, uninstalled lots of apps to no avail.
Is there a way to sort it out or roll back the update? My device is Asus Nexus 7 (2012).

I did a factory reset and it is still performing just as poorly.
