Pipo M9 Pro - System is very laggy at times and sometimes it freezes for many minutes or forever.

I flashed it with latest 20140319 firmware - official and Kasty and Chrome froze immediately when I visited cnn.com.. it was frozen for 2+ minutes :/ It said: "Chrome isn't responding - Do you want to close it?". Very disappointed... Lost so much time with this already and it just doesn't perform. Is there a solution to this or should I try to get my money back and buy something else?

PS: here is the thread on SE: http://android.stackexchange.com/questions/66324/android-tablet-very-laggy-and-freezing-for-3-minutes-slow-internal-storage/67467?noredirect=1#67467

This is a separate but maybe related question: why is internal storage performance so abysmal?

Please help

thank you,
David

On the opposite scale I find that the latest KASTY KitKat firmware to be faster and reduced lag /startup/and snappier than the previous 4.2.2 JB ROm, I was also frustrated with the previous JB ROM as it does not befit to be called a RK3188 (so much hype about it performance). But when I updated to the 3rd (latest,latest) version of the KitKat ROm I find it to be snappy faster boot up and responsive. I was on the KASTY ROM since the August 2013 release (I know what I am talking about) with only 1 exception that is the FrankensROM KitKat 1st version without the working GPS.

You might have a fluke device (RAM,SoC not working as it should??)

For your info I dont earn extra points/money or other benefits by promoting KASTYs ROM but I do earn a lashing or two from ADMIN if I slip my tongue on the Forum.

try to flash this file through CWM to complete the KASTY ROm GApps installation there are some mising files in the firmware.

OK, I tried to do that but when in CWM recovery mode I cannot mount anything:

D: Can't mount /sdcard/

I then tried to use ADB but upon connecting the USB cable windows said it cannot install RK3066 driver (?!).. This tablet has RK3188.

I tried to run "adb sideload update.zip" anyway but of course I get "error: device not found".

I'm stuck

Ok I did it... on Mac OS it worked with ADB. Windows didn't, don't know why.

I have tested browsing in Chrome and so far it looks promising... Cannot yet tell if it's a coincidence but in the previous 2 tries the freeze happened almost immediately. Would be so great if this fixed it! Will report after a day of using the tablet... thank you for this.

I would still like to know why AndroBench shows such bad results for internal storage performance though - does it matter? It shows 9.5 MB/s sequential read for my device while the normal for some other devices (Samsung SM-N900A, LG G2 etc.) is above 100 MB/s. Nobody answered this question and I've asked it on many places already

Still looking good!

I have noticed something though... there is no typing cursor anywhere... in Chrome, Gmail, other apps... anyone noticed this as well? I think there was no cursor before that last update you sent me.
