I haven't tried SuperPi, but Vellamo, CF-Bench, and GeekBench, which don't confirm your observations. Have you disabled AAL? That makes Lollipop feel "more agile" again.

Here's an older CF-Bench comparison I did. According to that, Android 5.0.1 has higher performance for native code, and particularly for Java code (probably thanks to ART).

That's wrong, that's NOT the only thing where 5.0.1 is superior. Haven't we discussed this before? ;)

First, the (theoretically) better performance I just mentioned. Second, fewer vulnerabilities - that's an old image, by the way, in the latest firmware, this test shows zero working stagefright exploits, but still says "vulnerable" for some reason. Also, note how in Android 4.4 the two buttons at the bottom, below "Resources:", are basically invisible, because Lenovo screwed with the theming.

Third, the Android WebView, Android's integrated browser component which is used by many apps (CF-Bench is one of them), receives regular security updates via the Play Store in Android 5. Not so in Android 4.4.

Fourth, Android 5 supports OpenGL ES 3.1 for 3D graphics, Android 4.4 doesn't (not that it's particularly important for most of us, I guess)...

Hello everyone! Quick question here, What would be the easiest/best way to fix an NVRAM error on this device?? I've found a few work arounds but nothing really sticks and its starting to really get on my nerves. I followed the dumb guide on Lenovos forums back when i got the device in November which screwed me. Thanks for the help in advance.

Also wanted to say Thank you to Tzul and everyone else that has contributed to this thread over the months, been following it since the original thread and I have sure learned a lot from you folks.

I'm not going to argue with you, Tzul, as my answer is largely philosophical and we did speak each other's mind (at least I did) before, summed up in these simple words: Those who are willing to sacrifice liberty for a little temporary security deserve neither ;)
[Android General] adrian1216:
I have one more question. Where SuperSu app is installed on device (where is apk file).

I don't see neither in /system/app nor /system/priv-app.

I see updates in store of SuperSu app. I would like to reach something similar - install custom app as system (like SuperSu) and update it using Google Store. [MENTION=5919159]Tzul[/MENTION] Can you help me? Or anyone else.
[Android General] zMILWAUKEE:
SuperSu is in the system/xbin directory, and no matter what version I've used so far they have all updated with no issues at all. The best method to install it is with TWRP ported by TZul, it's in the advanced menu of your TWRP. As far as where the apk is, I'll have to dig as I can't quite remember off the top of my head where the apk is.
[Android General] Tzul:
[MENTION=1454767]Old faithful[/MENTION] I don't see what "liberty" is sacrificed between Android 4.4 and 5, but okay...

[MENTION=7114808]adrian1216[/MENTION] The SuperSU app is installed to /system/app/SuperSU/ by the installation zip. Any subsequent update from the Play Store will be installed to /data/app/, however. The Play Store will never install an app directly to the system partition, because it is supposed to be read-only and unchangeable. Anyway, the SuperSU app has an option for moving the update to the system partition.
[Android General] adrian1216:
Ok. I see. It is interesting that GooglePlay is seeing this app, and is offering updates. For my app - which is manually moved to system folder does not shows this in spite of available update. Will check this again, and do more tests.

I have question. Is it possible to set "Android intro" when fresh system app is installed, as it was done. Where is saved information about necessity of displaying Android intro when boot completed. I need to get rid of it :)
[Android General] zMILWAUKEE:
Play Store will never be able to update a non original system app. If you moved an app to system app, one that was not originally a system app, if you want to update it you will have to remove that app, redownload the latest version you want from PlayStore and then put it back in system/app.
[Android General] Persizi:
I gave a chance to 5.0.1 for a couple days, but despite the disabled AAL, I still did not like how it runs and moved back to 4.4.4 again.

Anyway, I have a couple questions. Does anybody knows how to show the 5G networks in KitKat? Also, the sound sometimes goes up and down by itself like wave, anyone knows how to fix that?
[Android General] zMILWAUKEE:
Sometimes that happens with mine to. I've noticed that after a fresh flash it tends to do both of the issues mentioned. The way I fix that is to do a factory data reset after any full firmware flash or ota updates.
[Android General] Persizi:
Factory reset from TWRP or from the settings? Because I did factory reset from the TWRP and doesn't change anything.
[Android General] Old faithful:
Okay, I tend to get all Don Quixote on this so just bear with me ;) The liberty I was talking about is probably the liberty to set up the UI to my liking - such as to be able to work in white text on black background, a must for my old eyes who have significantly suffered after several decades staring at the glare of 'paper white' paradigm we've had to suffer since the Macintosh first came out and reversed the much more soothing and logical white text one dark background we had until then. At the age of 59, I've lost most of my shadow and darkness visual acuity as a result of being blasted day in and out by white screens and avoid them like the plague now, especially when word processing for any extended amount of time.

Lollipop UI and its 'material' design makes it even more difficult to set things up with white on black background and is, among the 'minimalistic' concept essentially removing options and the horrible flatness, the main reasons I dislike it so much, it's simply a question of significantly reduced interface usability, the opposite of ergonomy.

I can't wait to read about this in a few years when more and more people will be discovered to have developed disabilities directly as a result of this stupid, unergonomic ui decision, akin to corset use in the late 1800s and high heels ;)
[Android General] adrian1216:
[MENTION=5919159]Tzul[/MENTION] I read your script. I see that you modify /data partition only. What about /cache partition - Is it secure to clone this? I am going to try to check whether I avoid Android intro at first time launch.

Also I would like you to ask about your way of preparing updater script for twrp. I see that it is signed. I did not try it - but will this fail signature verification? If no, please explain me how? :)

---------- Post added at 09:43 PM ---------- Previous post was at 09:38 PM ----------

Is it possible (on this device) to display boot animation video in loop in whole time of boot?
[Android General] Tzul:
[MENTION=1454767]Old faithful[/MENTION] I prefer dark backgrounds, too. Luckily, every good app nowadays has a dark theme, therefore the Lollipop defaults affect me very little.

It should also be possible to decompile the framework-res.apk and change the default system colors. I'd try it, if I had more cause... ;)

[MENTION=7114808]adrian1216[/MENTION] The cache partition is pretty much only used by the recovery for log files, and by the Play Store for temporary download files. Therefore, you don't need to clone it, there's nothing essential there. If you do clone it, you might "leak" your serial number in the recovery log files, but that is quite inconsequential.

Update zips are signed just like APKs, with signapk.jar - there should be plenty of tutorials on the web. You need to choose a key for signing... for self-made update zips, people use a "testkey". Custom recoveries like TWRP recognize that one (if they've been built correctly). But stock recoveries normally only accept zip files that were signed with a secret key that is only known to the device vendor (Lenovo in this case).

Both of these do the same thing, as far as I know, wiping cache and data.

SP Flash Tool not usable to flash recovery !?

Hi guys !!!

I just wanted to flash TWRP recovery on my "Lenovo Tab 2 A10-70L" with "SP Flash Tool". But the strange thing is, that I can neither tick the recovery checkbox, nor the location column in the scatter table. To be precise: Nothing happens at all, no matter where I click. There's only a dotted rectangle appearing to the right of the actual checkbox, when I try to tick it. And when I click on "recovery" in the name column to set the location of the recovery file, the word "recovery" gets surrounded by a dotted rectangle, but no open dialog appears.

Until now I've already used "SP Flash Tool" for creating backups with the readback function. No problems with that at all.

Any ideas what's going wrong here?

Greets,

The SphereX

---------- Post added at 07:30 PM ---------- Previous post was at 07:09 PM ----------

It seems that in my "SP Flash Tool V5.1636" you first have to set the location for the recovery file before you can tick the ckeckbox. The other way around it's not working. As simple as that ;).

Greets,

I'm rooted with Lollipop 5.0.1 and want to install Xposed.Although I'm reading here that I have to install custom recovery, I've found various threads and posts here and elsewhere that Xposed can be installed on Lollipop without custom recovery with FlashFire. I want to avoid installing custom recovery. Has someone tried to do that with this tablet or succeeded?

See for example here: http://xdaforums.com/g4/themes-apps/guide-installing-xposed-locked-t3181593
[Android General] Old faithful:

[Android General] PhoenixSA:
Anyone solve the multi user issues yet?
[Android General] Tzul:
You're overly cautious, just install TWRP. You obviously do need it, because you'd like to install Xposed. Maybe FlashFire would work, maybe not. I doubt someone here can answer your question, because everybody uses TWRP.

When you're done with it, you could restore the stock recovery, if that makes you feel better. You can find TWRP (use twrp300 for Android 5) and stock recovery on my AndroidFileHost.

I try kingroot with lollipop 5.0.1 but at 35% it stopped and says unable to root. I tried 3 times the same happens again..

I have developer option on and usb debugging enabled.

Also, do you recommend downgrade back to 4.4 android? Is it faster? I bought this tablet to play only Clash of Clans, but its very laggy and has fps drops..
[Android General] Tzul:
[MENTION=5945816]lazostat[/MENTION] Don't use kingroot, use a custom recovery (TWRP) to install SuperSU.

Concerning the lag: disabling AAL should help.
[Android General] 1novca1:
Hello, I have a problem with internet connection on this tablet. When I am at home and I connect to my router, everything is ok, but whenever I try to connect to my Connectify hotspot made from my laptop, internet works properly only for a while, and then it does not go over 1 Mbps, until wifi on tablet is turned off and then on again, and then it works properly again only for a while. I have also connected my phone to the hotspot, but never had such problems with it. I have also tried to disconnect my phone so only tablet would be connected but the problem was still the same. Any advices?

Edit: Tried reinstalling 5.0.1 but that didn't help, even though the issue is gone after installing kitkat...

So now, can you recommend me any modules for kitkat which will make it look as lollipop as much as possible? At least the notification panel with buttons for screen rotation etc. (I hate those 2 panels which are present in kitkat (one for notif. and one for buttons)
[Android General] lazostat:
I have disabled the AAL and the lag is nearly the same.. I am talking specifically for the game Clash Royale. This is the main reason i bought the tablet..

How can i use custom recovery without root?? I dont understand..

How can i downgrade to android 4.4 ?
[Android General] Persizi:
Everything is described on the first page in the current thread.
[Android General] lazostat:
I have downgraded to 4.4. Do you know how to stop tablet from trying to download the lollipop update? Is this possible??
[Android General] chris5s:
Either disable/freeze the app using something like Titanium Backup or use a rooted system explorer to delete the app.

Peace.
[Android General] lazostat:
Which app is it?

Also, the dolby atmos bars are all on the same level. Is this normal? Is there any guide for settings?

I just inserted a sd high speed card. Should i change the default write disk from Internal storage to SD card? If i move games to sd card they will run faster and better?

Lastly, about the AAL :

I have installed it and then i did factory reset. Should i install it again?? How can i understand if its enabled or not?
[Android General] chris5s:
I think its this one in system/priv-app: LenovoOta_ROW_V5.0.132.70c943f.151223_all_rdv2key.apk

Peace
[Android General] Tzul:
Just go to the System Upgrade app and disable automatic downloads? The updates will never be installed automatically anyway.

Or you can freeze or delete the app, as chris5s said.

I recommend you disable the three toggles at the bottom and draw your own manual equalizer curve.

Here's how I've set up mine. Trying to boost the lower frequencies to make the speakers sound a bit better.

The "default write disk" setting only affects a few apps that pay attention to it. Mainly the default camera app - it stores captured photos or videos in the selected location. Do not move apps to SD card with the built-in Android function. That'll only cause problems, and will make things slower, not faster. If you have Xposed, you can use the "Obb on SD" module to manually move large expansion data to SD card. I wrote a bit more about that here.

A factory reset will just wipe the data partition. It won't affect the system partition, where the file resides that my AAL patch modifies.

If you can't see for yourself whether AAL is enabled or not, the patch will tell you when you run it again.

Can I update to twrp3 via Flashify?
[Android General] Sparkrite:
Yeah, I have many times before, just make sure you select "Recovery" and nothing else by mistake.
[Android General] nannycrick:
Just checking in. It's been a while since I've visited with my forum mates. I've been busy lately with local folks who have personal devices to sell and aren't factory reset! A very bad thing! I've also been taking care of W10 issues. No suprise there!

My Tab2 now gets about 16 hours of battery life thanks to the Lenovo Power Management apk. It really works great! It took some research to find a version that works since it's not "native" to the Tab2.

My fav device still runs fabulously!

Now if I could only get W10 to run like that!
[Android General] Sparkrite:
Which version of the app are you using [MENTION=4717484]nannycrick[/MENTION] ?

[Android General] Old faithful:
That's easy, format the damn thing and install a micro version of Windows XP (if you need old 16 bit apps to work) or Windows 7 and most importantly, don't rely on M$ (nor any American software company for that matter) for your security and privacy!

I for one am highly suspicious of any 'upgrades' - Software has a cycle like anything else, after it has become good it inevitably gets picked up by greedy types and becomes horrible after that, or rather, poisonous as it gains glitz and artificial sweetness. So it has become with Microsoft and most mainstream software.

My rule of thumb is, be highly suspicious of 'ugrades' - Software giants have succeeded into making the sheeple believe they must keep taking their pill or else all hell will break loose... For them, of course!!!

OK, so now that I stirred the hornet's nest and probably also ruffled some 'patriotic' feathers, feel free to shoot, after 40 years using computers I've seen quite a few flame wars, see if I care :rolleyes:
[Android General] nannycrick:
Nope...not shooting you down buddy. You have a very valid point! If Windows was soooo perfect, I wouldn't be helping folks fix their issues! Unfortunately Microsoft never released the truth behind most Windows issues.. the OS doesn't come FULLY enabled outta the box..ready to use by the general public. Windows has to be unpacked, tweaked, and updated to work in an acceptable fashion!

A tip for Windows users...any version of Windows...

Go to.. Control Panel >Programs>Programs & Features>Turn Windows Features On or Off. A popup box will appear. Expand it, and look how much isn't working in the OS! Enlightening!

Sorry.. rant over...back to the Amazing Tab2!

Which works better than any Windows PC!

I know, nannycrick :)... and I never mean anything personal when I rant online either and no one else should either, but I'd rather warn others beforehand ;) And although some may find my elucubrations strongly worded or opinionated, this is a philosophical discourse after all, where we argue, with reason or without, for the purpose of exploring issues and exchanging ideas and that is how problems turn into solutions in human societies, don't you agree?

As for this great device - I use it daily for perhaps a few hours so I rarely need to charge it more than every two days, as it uses at most 10% of battery per hour. Don't take me wrong, I would love it if I could use it as my main device but as long as we are severely restricted in terms of software ability (I stopped counting the times I tried to do something on it that I am used to do on the computer), it's going to be relegated to light work such as occasional email, showing pictures and documents, entering data, but as a creation tool it's got just too many drawbacks.

For example I found I can build an Excel worksheet on the PC and get a fair bit of it to work correctly on Android (not as much as I'd like, of course). Same with filling and signing forms, works great for that. It would work even better if it was more in the format of an actual sheet of paper, at least we're fortunate enough Lenovo had the wisdom to give us a 16/10 format screen instead of that horrible 16/9 that is so prevalent everywhere else... But I digress yet again ;)

I love your digressions Old Faithful. I've learned from your reflectiveness! Since installing WPS Office for Android, I've composed spreadsheets, used it to edit formatted & formulated sheets. It's tons faster than W10! I run WPS Office 2016 Personal on W10, it's FREE, and NOT trialware! My Tab2 still boots up faster than my 12 inch Dell Inspiron 3135...my newest acquisition!

(Got it from a PHD candidate who got frustrated that it wouldn't update from W8.0. Updater code was broken. Fixed it with MicrosoftFixIt Tool!)

Spreadsheets are very easy to compose in tablet. Fonts are also easy to come by for the Tab2...

Make a new folder on your desktop - Mobile Fonts.

Then go to Windows C drive>Windows>Fonts. Copy any true type font (.ttf file designation) into that folder.

Then copy & paste onto your sd card storage. Then make another copy to:

internal>Android>data>cn.wps.moffice_eng>

.cache>KingsoftOffice>. fonts. Then reboot. Those fonts will then reappear in the Fonts pulldown in WPS. Keep a fonts folder stored on the sd card as any cache cleaner will delete them. I keep a duplicate copy stored in Fonter. I'm running Playfair Display Italic as a system font. Very stylish!
[Android General] Old faithful:
WPS... Hehehe... You practically took the words out of my mouth, so to speak... I use Excel 2000 and it does everything I need, including complex data regression right from my machine, none of that 'sign in here please' servitude that has become the hallmark of modern computing, and if anything I have found that WPS is a natural extension of that version of Excel under Android, it only lacks the data analysis tools Excel has... But as far as fidelity in format and functionality I love it! In contrast, Excel for Android is a serious piece of condescending cr@p that is so under featured and aggravating I can't imagine how anyone would willingly want to use it (unless of course they are using the modern version in Windows and don't know any better)

That is definitely a source of frustration for me as well - It seems impossible to get my laptop to use less than 35w even if I can make it boot in 45 seconds - I guess it's just the nature of the beast, it's like comparing the Titanic's engine to the one in a Tesla! No way to make it use less power I'm afraid! That's what I'm paying for having a quadcore processor and a video card you could fry an egg on while it's calculating the shape of the universe with its 320 cores!!! Naturally, it's battery is more of a UPS for when there are temporary cut offs than anything else ;)

Way to go!!! Sometimes it's good to be a nerd!

Use and modify using WPS on Android, no problem! But for heavy lifting? No thanks, I prefer to work on a mechanical keyboard with a nice 30 inch screen running at 2560x1600 in front of my face :D

Yeah, it was a bit of a battle until I figured that one out, as no matter what I tried, it just wouldn't read any fonts I placed in /system/fonts... Grrr! Putting the fonts on the Internal SD Card in a /Fonts subdirectory did the rick as it seems WPS complies with KitKat's tyrannical 'hands off the external SD Card' policy and refuses to read fonts from the external SD card :rolleyes:
[Android General] nannycrick:
WPS Office for Android is about as heavy duty as an office suite can get for Android. The Personal edition for Windows however, does contain as many bells & whistles as MS Office Home. I've run pivot tables with it. It's good, and can run anything! My main pc...the Dell is only a 12 inch, so everything looks the same from PC to Tab2.

Yes...I got it cheap for $50 because he got pissed at Microsoft over the updater issue, and bought a Mac! It hasn't been updated for two years because of the updater! Took 10 minutes to fix it, and 7 hours to load updates, and then W10!
[Android General] nannycrick:
And as a side note... I did contact Microsoft on that updater issue. I got a "virtual" tech that sent me webpage posts but no help. When I "texted" them that, according to the previous owner,it hadn't been updated since new....ever! He even tried to upgrade to W10, but it just "spooled" without loading. He decided to sell me this one and buy a Mac! I then got a live tech on the line who sent me the FixIt Tool. Ran it & Eureka! He even sent me a product key for W10 Home!

hehehe!
