[General Questions and Answers] fipsy:
Depends on the apps you install. Most apps today require between 5 and 15 MB. But of course there are apps that need much more space. Like browsers (chrome is a giant memory hog) or navigation systems. If you move big apps to the SD-Card (in apps settings if possible) you can also save some memory.

If you count together the memory occupied by apps and the free space you should achieve about 960-1000 MB.

There is no way to increase the internal memory. I suppose most of my apps are smaller than yours. ;)

Small update OTA to 4.2.2 today.

Don't know what it did or what it was meant to do, but pad seems to be running OK after the update.

Lost root and had to re-root afterwards as no SU left in system/xbin.

Very interesting! What is the date of this update? 12/19/2013? What was the date of the previous android version? 12/14/2013? Seems there has been a pre-release from 12/14 that some people got, but not all! In the german HSG1279 forum there is a user who reported the same. He was offered an update from 12/14 to 12/19 today and he asked what the differences are...

Meanwhile I have to revise my opinion about this tablet. Since I did the factory reset after upgrading to Android 4.2.2 it works like a charm. No noticeable lags. But of course you cannot expect that the browser loads complex websites as fast as for example Firefox does on a 2,6 GHz dual-core PC. A website with very complex graphics that needs about 3 seconds to load on a PC needs about 9-12 seconds on the tablet. This is related to the the GPU that is not as efficient as for example a NVIDIA GeForce GT 720M. But while the page is loading you are able to scroll up and down without lags. This wasn't possible before.
[General Questions and Answers] moss20:
well,I have a single core tab now and a tegra 3 lg optimus 4x so I just need a new tablet with hdmi,good performance (if possible like my 4x) and good battery life,no gaming or complex operations.

It has to be cheap 'cause with a bit more money U can buy an asud t100 with win 8.1.

To cut a long story,I have 2 possibilities :

-this tab

-a bit cheaper 7.85 ipad mini-like tab with 1.6ghz cpu 530mhz gpu 1 gb ram,16 rom and 4700 mah battery but it has wifi problems (just after an update,maybe cuold be solved)

now,it scores 19500 points on antutu but sometimes it lags so I think if that hannspree tab is more optimized,I nevermind antutu scores and I'm going to buy it.

Okay, this is more concrete. I really like to watch YouTube videos in HD on this tablet. They run absolutely fluid without any dropouts. As in general watching videos is really fun with this tablet. Not much difference to my 1080p TV set. If the pad is connected to the TV via HDMI it's hard to distinguish between TV-program and YouTube streams. So for video applications I would recommend it. WiFi works without any problems. No drops and fast and reliable reconnection after standby. But it's no rocket, just a machine for normal requirements.

I just ran Antutu to compare to your value. The scrore is 11099 (details see graphic below). The system stability test gives good results between 31.5 and 35.5.

So just from this values the tablet is not the greatest stunner. I think RAM and storage are quite slow. But the rest is okay. The question also is: How reliable is this test?

[MENTION=5110154]fipsy[/MENTION]

Is there any way we can get this tablet to run at 1.2 KHz as advertised, or were we sold a "lemon"?

I find it hard to believe that "Hannspad" told "lies" when selling this tablet.

Again I must thank you , Fipsy, for all the time and effort you have put into this tablet.

Thanks to you, I now feel confident flashing whatever I want knowing that I can

always return to a working ROM.
[General Questions and Answers] fipsy:
Ainol advertises this device (Novo 10 Hero 2) with even 1.5 GHz. Omegadrive said that with 4.1.1 it was no problem to clock up to 1200 MHz. But with 4.2.2 there seems to be no way to get above 1008 MHz so far. All my tests showed that the frequency of 1200 MHz seems to be available to the governors but it cannot be set resp. it is just ignored if it's set.

So far I don't fully understand how CPU clocking is internally accomplished on this device. It's quite different from the devices I know. Somewhere there is a switch that sets the minimum and maximum CPU speed. And the maximum speed switch is simply always being ignored. If it is set to 720 MHz the device will still run at 1008 MHz. That is why it also will not run at 1200 MHz. The minimum switch however is obeyed. So probably the problem is that the maximum switch has no function. It's always set to 1008 MHz. This maybe an error in this Android Version because on Android 4.1.1 this was no issue. Perhaps we'll find a way to change this.

I'm probably an ambitious nursery child. :D

That's the meaning behind my effort. Having this confidence is the basis for all future developments aside from the stock ROM. I hope there will be some other freaks investigating on this device in the future as I'm just an interested user. As I see it's becoming popular more and more.
[General Questions and Answers] andy572:
Today i bought this device for playing with^^ just saw described issues here, and saw some bad things on the device - tested only with web browsing and start playing "Subway surfers". The quality isnt good at all, but for this price (in germany i have payed only 169€ - should be around 150$)... So ok, i'm a real developer - do you think, we can tune some things?

For the CPU clock, you cant overclock a CPU without a kernel that support the frequencies - so we need a better kernel. Do we have a kernel source code or do we have a compatible kernel source code? What about 3D and 2D - curently i dont know about the internal GPU, so do we have some hardware specs i can read on?

Greets from germany

[General Questions and Answers] fipsy:
But we didn't want to overclock. We just wanted to clock 1200 MHz as described by the manufacturer. With 4.1.1 this was possible using CPU Tuner or utilities like this. But 4.2.2 stops at 1008 MHz. This is 20% less than the manufacturer promised. Could even be a reason to claim. Probably due to an error in the kernel that ignores every maximum frequency that was set.

/sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state looks after some hours of usage for example like this:

252000 278
360000 216
576000 29763
720000 905
864000 112
900000 18677
1008000 3847973
1200000 0

Meaning the frequency of 1200 MHz is known to the system but was never used.

Unfortunately we have none of this. :( The only thing we know is that the "Ainol Novo 10 Hero II" is technically nearly identical to this device. This was helpful finding the right USB drivers and creating the CWM-Recovery. But furthermore we are completely in the dark...
[General Questions and Answers] andy572:
Correct, i understand the problem ;) But, the kernel has hard coded cpu freqency map/table and a governor who is watching about that. So, you have to modify at first this map/table so the governor is happy - in other words, if we dont have a kernel source we can't have more than 1008Mhz :(

I'll spend some time to read out the hardware and find a kernel where is matching our hardware. Most manufacturers are using the same hardware - they only name a hardware part some other to respect all patent issues :D
[General Questions and Answers] fipsy:
I think the frequency table is okay because all possible frequencies are listed to the governors. But there is a maximum frequency switch in the kernel. And I think this switch has a wrong setting. If you're looking into the 4.2.2 kernel with a binary editor you'll see a section like this:

There seems to be a switch or function "leopard_cpu_highest_speed" that sets or gets the highest CPU speed. I suppose this is set to 1008 MHz. If we could find the position where the value for this switch is located we could patch the kernel. It's a dirty method but it probably will work. ;)

That would be great! And it could perhaps bring back the internal support for USB surfsticks that also got lost from 4.1.1 to 4.2.2.
[General Questions and Answers] shouldbeshroomin:
I was a little confused about doing a reset with the stock recovery after flashing CWM. It does appear to be a little slower since the 4.2.2 update so a full wipe through CWM then restore won't have the desired affects? Must be reset through the stock recovery? I guess I could just see for myself right
[General Questions and Answers] zephyro5:
Hi from a new user a little disapointed!

First, I don't know much, but if I can help...

From my side, I've the same /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state: the frequency 1200000 equal 0.

But should I care about cpu1, cpu2 and cpu3? (it is a quad core, I believe?). Because cpu1 looks cpu0 with lower numbers, cpu2 has the same states but with 0 everywhere and I'm unable to open cpu3. It looks like more un dual than a quad core...

And is the boot.img the kernel file? I ask this because I have the leopard_cpu_highest keyword but it starts at the hex address 004DA01C while yours is at 004D981C... Is there different 4.2.2 kernels?

Thats right. As far as I know the only reason for recommending a factory reset with stock recovery was, that no one tested it with CWM Recovery so far. :silly:

---------- Post added at 04:50 PM ---------- Previous post was at 04:25 PM ----------

Concerning the frequencies you only need to look at cpu0. I don't know if the cores of this CPU can be clocked with different speeds. Some CPUs are able to do this. But I think on this CPU all cores are always clocked with the same speed.

The boot image contains the kernel - among other things. It also contains technical information about memory layout and a ramdisk.

0x004DA01C - 0x004D981C = 2048

[General Questions and Answers] fipsy:
By the way: About 2 or 3 weeks after resetting the tablet it began to lag again some days ago. Meanwhile it's nearly as slow as some weeks ago: The browser gets frequently stuck while loading pages and last night the CPU stopped in the middle of the night and then drained the battery so I had to reset the pad in the morning. It's exactly the same issues that caused me to reset the tablet some weeks ago. Seems this "cure" only lasts for some weeks. :(
[General Questions and Answers] Satoooooshi:
Have you done anything to the tablet since resetting? Like reconfiguring or the something like that?

I ask because my tablet still runs pretty good. I've turned off all animation though. I also did the factory reset with the CWM (I didn't know how to flash stock--still don't).

I've also noticed that the battery is much better! My wifi turns off when the tablet sleeps and I don't have the location services on (don't need them).
[General Questions and Answers] Bluze:
I sent mine back yesterday for a refund. Had the exact same thing happen. Slowed down, was taking a minute or two just to load pages. Then Tuesday, it died again like I said it did before. Nothing but a dim backlight, no logo, no boot. That's twice it's happened in less than a month. Too bad really. When it was working properly, it was a pretty fast little tablet, but I don't want to have to reset everything every couple weeks. I don't know if it would have "come back to life" again like it did last time but I'm down to a little over a week that I can get a refund so got to do it now.

Fipsy, thanks for all the work you've done on this! I'm gonna find another tablet to play with in the next few weeks, so hopefully I'll see you on another thread!
[General Questions and Answers] fipsy:
No, I didn't. Nothing that could have caused this.

I've turned on the animations but I always had turned it on and it was fast anyway.

http://xdaforums.com/showpost.php?p=49376465&postcount=204

The battery is fine with me, too - as long as the CPU doesn't get stuck. The lag also isn't as bad as it was some weeks ago. But the tablet is much less smoothly than it was after resetting.

---------- Post added at 02:19 PM ---------- Previous post was at 01:54 PM ----------

Very interesting. Though I feel sad about your problems. A refund after more than two weeks would normally be impossible in europe. Except with some stores that offer this voluntary. They normally would try to "repair" it. And mostly you get it back unrepaired with the notice "no error found". As someone who sent his tablet back because of the same error and reported about this in a german android-forum.

That's really evil! I haven't had this before but I heard from a lot of people having the same problem.

The lag is not a hardware problem but it depends on the new android version 4.2.2. It could be an alternative to restore to 4.1.1. I hope we can fix this some day. Perhaps with a custom kernel.

I'm sad to loose you on this thread. :crying: If you have found a new tablet please let us know!

[General Questions and Answers] Bluze:
I was lucky...I bought it with my Amazon Prime account. You have 30 days to request a refund or exchange. I had already requested and received the refund after the first time it died on me. But after it started working again, and after doing your mods to the device, it was running so nice I had planned on contacting them and telling them to bill me for it again. But then it died again. I guess the timing was good though, I still had a week left before the deadline for sending it back.

Oh, I'll still be keeping up on the thread! Just won't have anything to contribute now that I don't have a Hannspree to work with. But I'm very interested to see how this plays out.

[General Questions and Answers] coltracer:
Thanks for the help!

I want to say thank you to all involved in this thread! :good:

I bought this tablet a couple of days ago, booted it up and made the mistake of updating to 4.2.2 right away. The thing was just awful. Even with no apps installed by me the tablet was lagging. I read this whole thread, did all the reset tricks, it didn't get better. The astonishing thing was, some apps were really fast but the launcher and browser were so bad, I almost wanted to chuck it against the wall. This is supposed to be quad-core? jeeez....

So, the only option was to downgrade to 4.1.1 to compare with 4.2.2.

I couldn't have done this without you guys, I pushed CWM-Recovery on it, tried the update.zip trick and almost bricked it. :D. Then I copied the

4.1.1 recovery on an external SD, flashed that and my tablet was working again.

4.1.1 seems almost blazing fast compared with 4.2.2 to me. The browser is MUCH better. the overall feel is better. I'll have to observe this over the next couple of days but so far I'm happy.

Thanks again!

There are a lot of devices using similar hardware. But not exactly the same. Displays and other components may be different. So you cannot simply use the firmware for Ainol devices for example.

You're really welcome! I'm also curious about how this ends. :)

---------- Post added at 11:54 PM ---------- Previous post was at 11:31 PM ----------

You're right, 4.1.1 has much more performance than 4.2.2. And 4.1.1 has further benefits like the internal support of UTMS Surfsticks (e.g. Huawei E1750). I also still think about downgrading to 4.1.1. But there is one thing with 4.1.1 that's really evil: The display keyboard often swallows characters. It drove me crazy to permanently correct what I had written. Perhaps this problem can be solved installing a different keyboard. But I didn't try this.

I think I will also revert to Android 4.1.1 soon. I just found another really bad issue on Android 4.2.2:

If you connected an HDMI device to the tablet on Android 4.1.1 a popup menu appeared for choosing the screen resolution. This menu doesn't appear anymore. There is always a resolution of 720x576 set. And this is really, really poor!!! Together with the lost support of UMTS surfsticks and the annoying lags this makes Android 4.2.2 a real No-Go on this device. :(

What bothers me on Android 4.1.1 is that you are not able to lock the screen rotation in portrait mode but only in landscape.
[General Questions and Answers] piaaf31:
This issue can be solved easily : in Settings > Display > HDMI (touch the word and not the switch)

Set the resolution you want. And only after that, plug the cable in.

There's a minor issue though, it's impossible to set the resolution when the cable is plugged in.

I tried and as it happened for you, it sets back to 720x576.

---------- Post added at 10:09 PM ---------- Previous post was at 09:41 PM ----------

BTW, for me Android 4.2.2 works pretty good. I use Pimp my ROM and Greenify, and since I updated to 4.2.2, with these apps, I have no problems, even before doing the factory reset.

The browser isn't very fast but it's usable.

And I want to say again thank you to all the persons who work on this device.

Otherwise, my device would have probably ended in my kitchen as a cutting board :)

[General Questions and Answers] fipsy:
I updated to 4.2.2 on January 11th and had no issues with battery drains but with heavy lags occuring again and again. I could temporarily solve this by wiping the partitions and restoring a CWM-backup that was made just before wiping. But after about 2 weeks the device began to lag again. As with many other users here in this thread. Bluze sent back his tablet because of this issue.

With 4.2.2 I had no battery drains except after installing Pimp my ROM and doing some of the tweaks.

Yesterday I reverted to Android 4.1.1 using a CWM backup made on January 10th. My god! I had completely forgotten how fast and fluently this device is able to work with android 4.1.1! It's a difference like night and day between these Android versions! If you have used Android 4.2.2 for about four weeks and after this time are reverting to Android 4.1.1 it's like coming from hell to heaven! I never want to use this 4.2.2 botch again!!!

On android 4.1.1 I now tried to reproduce an issue reported by Omegadrive (being able to boost to 1200 MHz):

I had an Antutu score of 11099 on Android 4.2.2 though it never showed up to run at 1200 MHz. On Android 4.1.1 I tried to apply the boost governor setting using Trickster (only available for the interactive governor) and it reported to have been running at 1200 MHz. Nevertheless the Antutu score is just about 9800 though the device is objectively running faster than with 4.2.2. It's quite weird. And I think you cannot give anything on what Antutu says!

I also noticed that Antutu changes the governor from "interactive" to "performance". If you start Antutu and then look into the governor setting you will notice this. So any setting that you applied to the interactive governor will have no effect on Antutu. And it also seems that there is no app that is able to clock the device to 1200 MHz - except Antutu. All these things are illogical.
