Is the Sero 7 sluggish with newer software?
« on: December 09, 2015, 03:19:33 AM »
I have had my Sero 7 for a few months now,  and I've been using door 5.01. At first I had the 3c toolbox and xposed installed, then tried it without xposed, now with xposed and no 3c toolbox... Honestly the stock dopa romantic seems more responsive than with 3c's tweaks but it's still so sluggish.

I don't blame the tablet, but the software. It primarily slows down with Google applications.  Chrome is dreadful and often crashes, but just simply bringing up the keyboard takes 5 seconds after a text input field is selected,  and often times hitting a button or link is delayed by the same amount. It's so frustrating because often I can't tell if I haven't pressed the screen firmly enough or if it has just lagged, so I wind up pressing it twice more than is needed... Anyway lots of other things are just slow as molasses and make the entire system unstable,  Google Maps is practically unusable...

I just find it weird because I got a Amazon Fire the new 50 dollar one,  and it is so much more responsive. Sadly it's missing half the features, has like less than half the battery life as the Sero but it is so much snappier.

Is the hardware on the sero just a little too aged for how resource intensive Googles applications are? I hate how bloated and unstable their apps are but they are very convenient too, I enjoy the cloud based approach. Most other apps run fine,  maybe a little slow but not as predictably torturous as any Google app will be. Even Netflix Streams HD video without a hiccup. On the other hand just long pressing a link to open it in a new tab with Chrome brings the system to such a halt thst power cycling is faster than waiting for it to catch up.

I'm basically thinking about making the Fire my dedicated home and Web tablet, and using the Sero for GPS and media. Just writing this post has made the processor so warm I can feel it through the back of the tablet!

That's why I have two Sero 7s. One has nano google apps, the other has no google apps. If I need to install an app from Google Play, I install it on the Google Sero, use apk extractor to put the apk on an sd card, and transfer it to my non-google Sero, install it, and voila - I still have a speedy Sero with all the apps I use. I think the second Sero cost me under $50 on Ebay. A little clumsy, but the results speak for themselves.

Yeah I had another Sero for a while too but the charging port went bad. Went to a local shop to have it repaired and it cost about that much, all they did was put in a new motherboard, and now its charging port went bad as well. I have always had Google Apps on both but not the full package, I usually used the nano package and then installed Whst services I needed from the Play Store, but even the Play Store seems to slow it down. So you just sideload the Google Apps without needing play services?

I use Play Books, Sheets, Gmail, Maps, Drive, and Chrome.

Hi SagaciousKJB.

You shouldn't be experiencing that kind of lag on your tablet.  Two things come to mind..

Did you do a full wipe when you flashed the ROM, not just a factory reset, as reset doesn't really do a good job of reformatting data.

And did you use 'restore from google' when setting up the new rom.. As this choice is probably the culprit.  Restoring apps and data from google can cause some serious lag. CAN.  Not always, but CAN.  Not all the data that's restored is compatible with a different rom, so restoring data from one rom to another can cause the type of behavior you are speaking of.

You could boot to recovery and do a full wipe again, reformatting data as well. Then reflash the rom.  And the gapps if it's part of the rom's instructions.  Yes, you will loose your data.  And yes, if you restore it from a backup, most likely the same effect will happen again.  UNLESS it's that same rom. example:  Full wipe and flash lollipop and restore lollipop data from a backup.  That's ok.  Restore from kitkat or marshmallow data, not so good.

When you set up the tablet, choose setup as a new system, instead of restore from another device.

You don't need to have google on your tablet, if you don't want to.  Pretty much any app on google play is available in the amazon app store, (almost. more and more are being added) which only requires the Amazon underground app, no framework files like google requires.  The ones that aren't can be found from third party app stores on line.

You can use ES file manager to make backups of any of your apps, including those from google play, and install them onto your tablet without the play store.  Some, and rom toolbox pro is a perfect example, will not run though if they can't connect to the play store to verify you paid for it.  But you can download the paid version from a third party and have it run. (for free, so go figure) Rom toolbox is the only one I have ever had issues with.

If you're using marshmallow here is a guide to use marshmallow without google.. A guide only of course.

Cache and Google backup aren't an issue, this is from a fresh install of Dopa 2.7. I always make sure to wipe the caches and don't keep data either.

Not sure what "sideload" means. I copy the apk which I create from the installed app using apk extractor, from one Sero to the other, than click on the apk to install. Simple stuff, and Google stuff does not slow the tablet down.

As in using adb to install an apk instead of the tablet itself.

I flashed the new Marshmallow Dopa last night. It's running okay right now with only Nino Google. I'm betting as soon as I install Chrome it slows down though.

 Lucky me, when you talk about losing the backups from Google, I don't recall it even asking this time, I just logged in. I mainly like to stay connected to the cloud so Chrome remembers all my passes and such.

Edit:
Well after a little while of using a fresh install of Dopa  Marshmallow I tried Chrome and it's back to running very slow.

It's part of the initial setup after a fresh install. Prior to lollipop, after flashing a new rom during the initial setup of the tablet.. You get a screen that asks if you want to add a google account. You say yes, then the option to sign in to an existing account or make a new account appears. Here. If you say existing.. It allows you to input your email and password. The default is always checked to backup to google and restore from a previous device. This is what I'm referring to..in my opinion, it's best to remove the checks.

Starting in lollipop, the initial setup of the tablet changes a little.. Now, instead of the previous mentioned screen, we are faced with a different window that asks if you would like to setup as a new device or restore from a past backup. There's a pull down window now that allows the user to choose.  My experience with this is, if you choose anything here you're going to experience issues. Major lag on your device. Choosing setup as a new device gives a clean install without lag. Again, my experience. Others may experience something difference.  It's best to root, have a custom recovery, and backup and restore your data from your nandroid. AND, even that's not foolproof from one rom to another.


I can honestly say, I have never experienced a lag on my tablet from installing and using chrome. Or google in general, for that matter. ( and I'm not a fan of being all ' googled' out)  I do use chrome on my tablets, as I find it the best after experimenting with many.  And I find it faster with location services on, opposed to off.  Maybe my imagination, but I don't think so.

Lag on devices is a common complaint.  It happens for a lot of different reasons, as each of use our tablets for different things. Sometimes/most of the time, it's misbehaving apps.  Not playing nice with another.  Finding the apps/app can be a chore, as you have to install them one at a time, adding them and testing, until you find the culprit.

Experiment with the roms available for the sero until you find one that works right for you.  The newest doesn't automatically make it the best. That's for sure!  It depends on each user.

I would suggest trying liquid smooth and the last kitkat  dopa rom , compare them against lollipop and marshmallow.

Make a nandoid/full backup of each one. And use each one a few days at a time.  With the backups, you can bounce back and forth to compare them. (Full wipe inbetween each) You'll know which one is right for you.  Then you'll be happy. And you won't be wondering ' hmm, I wonder if I should try..".

Okay yeah I think I have unchecked those boxes in the past and still had lag, but I'm not sure if I bothered to unchecked them this time since it never seemed to make much of a difference.

Right now I'm trying a pretty minimal array of applications. It really seems to be Chrome thst is the weak link, and that sucks because I feel like it's the only browser I really like because of the password remembering. I tried the default browser and it won't remember certain passwords and thst is infuriating to me. Normally on a desktop I just use a password storage app I made, but on Android the best I can do is login remotely to my PC with ConnectBot and run the program in the terminal and copy and paste. But that is extremely cumbersome.

Sad that's the only real reason I want Chrome.

Anyway I have two restores now which are basically vanilla Dopa installs with my Google stuff setup, one Lollipop the other Marshmallow. I suppose I can try some different roms, not heard much about Liquid Smooth, I thought it was defunct??

Edit

Okay well I did a system wipe and reinstalled Marshmallow Dopa, and all I have installed is Chrome, Swiftkey and Photobucket so far. These are the options I checked for what you mentioned....



Should I have wiped the internal storage beforehand too? I just did system, data, and dalvik/cache

Edit: A few hours later and it is still extremely laggy

I would uncheck the backup to google also. No point if you're not using the restore from google option. And it never has restored passwords anyway. Not for me anyway.. It's unreliable, imo.

Re liquid smooth: nope not defuncted. I guess it hasn't had a recent update, so still on kitkat, but it's an excellent running rom.


http://sero7forum.com/sero-7-root-hack-mod-and-development/custom-roms-for-the-sero7-pro/


As far as what to choose when doing a clean install, this is what I choose: ( not all options may be present in every recovery, so choose the closest choice for philz or cwm)


Boot to recovery.
Wipe cache & dalvik cache
Make a backup of rom
Choose wipe/reset
Advanced wipe- choose wipe system, data, cache, internal storage is optional ( I usually don't wipe internal)
Then choose format data ( may require you to type yes)
Choose install - from ex sd card ( thats where I always keep my roms)
Choose and flash rom
Flash gapps
Wipe cache
Wipe dalvik
Reboot system.

I never restore any data on setup.  I don't have anything to restore. All my photos, music, and files are kept on the external sd card. So it's there, always. Game data I don't care about.

Edited to add:  dopa roms don't fully function properly until after a few reboots. So I do  initial setup. Then reboot. Add 1/2 my apps. Reboot. Add the remainder of my apps. Reboot. Then I'm good to go.

For you, because you are very minimal with apps. Just do a few reboots after setup.

Okay cool, I'm going to try flashing something different then. Maybe something KitKat based would run better but I worry since it's already up to Marshmallow thst it won't be very well supported for very much longer.

Has anyone ever got SlimRom to work on the Sero?

What do you mean by 'won't be very well supported very much longer'? 

Apps and games that work now just won't stop working on kitkat. Development usually supports everything from  the time of development and everything older. And there are still plenty of brand new devices still being released with kitkat. You'll be fine with kitkat.  The only real argument is security. With each new OS comes security changes and tweaks. And Marshmallow and the OSs that follow will bring big changes in security, as google will move forward with google pay.

I always recommend a security app. Avast is my favorite. Find one you like after you find a good rom.

I run both Avast and Malwarebytes. Always good to have more than one AV.

I tried installing Liquid Smooth but the  Play Store doesn't work, just crashes as soon  as it's opened.

It did seem a lot faster than DOPA though.

Most likely google framework needs updating.

Try settings > apps> google framework > UN install the updates. Then boot to recovery and wipe cach. Reboot system.

Upon homescreen, open google play. This should force google to update the framework, stopping the force closing.
