[Q] Android 4.1.1 stability issues on Chinese tablet - Android Q&A, Help & Troubleshooting

Hi All,
This is my first post and this tablet is also my first introduction to the world of Android.
I recently bought the following 7" Android tablet:
w w w .lightinthebox.com/7-inch-multi-touch-screen-tablet-hd-dual-core-1-6-ghz-android-4-1-1_p494283.html
I received this tablet yesterday and set about learning my way around Android 4.1.1 and installing various apps. Now I know what you're thinking, that this tablet is a cheap Chinese tablet and I shouldn't be expecting outstanding performance and reliability but I'm sure the following symptoms are of an OS nature as opposed to hardware.
I started just using the apps that came on the device, the browsers, the video player, the play store, etc. and started to get random resets and freezes on the device. After a bit more playing I found that when running the Android browser on the OS it was auto installing Flash Player which I've read can cause stability issues on Jelly Bean. I uninstalled Flash and stopped using the default browser in favour of Chrome as that didn't auto install flash. Since doing this the OS has been a lot more stable but not brilliant. This morning alone it has crashed on me twice viewing google images in chrome. When I say "crash" I mean it reboots and I see the "Android" logo.
Are there any known issues on Jelly Bean 4.1.1 causing instability or is it a case of I have to live with it on this cheap tab? Are there any hints, tips, admin tools, or configuration changes I can do to improve performance? If the recommendation is to rip off this OS and put on another I don't mind giving that a go as this is becoming a bit annoying.
My about page on the device reads as follows:
Model Number - Tab70s
Android Version - 4.1.1
Kernel Version - 3.0.8+
Build Number - RK30_ANDROID4.1.1-SDK-v1.00.00
Any help is gratefully appreciated.

I'm trying a few different things. Swapped browser to Opera but I have now had a crash when in the play store so I'm trying Nova Launcher instead of the standard Android launcher. So far it appears to be a bit more stable. No crashes as of yet but the pessimist in me says I've not seen the back of this issue yet.

After a bit more research and trying to decipher the Chinese writing on my tablet it appears I have a "Yuandao N70S" tablet but I'm struggling to find much info on these at all.
Anyone?

On my non name tabel with the "RK30_ANDROID4.1.1" image, I can get to the recovery by:
1. unplug the charging power (I can't get the next step to work with the power pluged in).
2. turning it off and the press the vol+ and power button. That will show the android robot laying down with the belly open and a red ! mark
3. after 10-15 seconds I am able to press vol- and power button to get to the recovery menu.
The navigation keys there is vol+/vol- and power, but the vol+/vol- key is very sluggies, so I keep them pressed for approx. 2 sec and the when I release it, the highlighted menu line will shift.
There is a "wipe data/factory reset" menu item, but I have never tried selecting that, so don't blame me for any briking
Hope it helps...

Try to find a cm10.1 that works in your device. It's much better than the stock roms from rockchip.

[Q] Tablet identification

Hi
I have purchased a tablet that was sold with a problem of freezing occasionally. It was sold as a M009s ( no other info or box ).
It booted up and worked faultlessly for a short time and then sure enough it froze, I shut it down with the power button and it froze on boot up screen.
It occasionally booted up and worked OK but froze more often than not on either boot up or when in use.
There appears to be no info on the tablet as to its make so I checked specs on my tablet info and opened it up and got this info from inside.
My tablet info - Motoroler / Droid 2 Global - Android 4.0.3 Eng Snake 20120116.191929 SDK 15
- 800x480 dpi / Ram 448 / Flash 8GB / 1 core Arm v7 rev2 (V71) Exdroid / 1008Mhz
Main chip - All winner A10 c5036ca
Main board - Topwise A721-v4.2.0 ( 2012.03.26 )
I am quite new to tablet roms etc but managed to flash a new rom which I thought was the correct one using Livesuite.
The Rom was LY-F1 Allveiw Aldro speed by Seby
The tablet seemed to work fine but then froze up again.
It only occasionally boots up correctly but normally freezes on boot up screen or not long after boot up.
I don't know how to tell if it's a software or hardware problem being new to the whole Android O.S.
I have been chasing my tail trying to find a solution but am getting nowhere. Please if there is somebody that has any solution or can point me to a link related to the problem I would be much obliged.
Thanks Hopefully
Kev

[Q] Tablet Became Too Slow with Delays

I have PIPO M9 Max with custom ROM with 4.3 Android OS.
After a while tablet started lagging. Just serious lags when operating tablet like:
unlocking screen, downloading file, switching tab, launching app etc.
Startup load and login times increased and once has to wait before unlocking
screen after startup.
I have heard about Android 4.3 lacking TRIM command for tablet's internal NAND
but such condition never happened to my Nexus 4 that has 4.3 on it.
Does anyone know what can be done for tablet? I am not sure upgrading to
Android 4.4.4 will help long-term...

Alcatel Onetouch Flash 6042D Tips and Tricks

Hi Friends,
I have started this thread to invite all developers and users to share all good tips and tricks for the device Alcatel Onetouch Flash 6042D which is such a good phone looking at the specification and Quality of Hardware. A very first thing special thanks to Flipkart for bringing this device to India that too at an affordable prize and also for providing excellent service as they always do
Talking in brief about special highlight of this device, it features a 5.5 inch screen, 1.4 GHz MTK 6592M Octa core processor, 3200mAH battery which lasts for minimum 1.5 days even with heavy use of Wi-Fi for 8 hours Secondly even Alcatel engineers have done awesome work by working so much behind update the stock android and making it so beautiful
Coming to point as I have own personally this device and looking at user reviews few users faced some of the issue one of which even i came across. So if you are one among those users than follow my below tips: -
1. Network Hanging/Stuck Issue: - For users, who came across Network hanging issue which happens specially when you are roaming with this device as i have personally witnessed the sole reason for this is Google Apps update. Their is no reason to blame alcatel for this. MY testing till now has revealed that This is caused specially by Google Play services and Google Apps update that happens automatically if you are on Wi-Fi network.
To get rid of this: - First of all don't update any of your google apps until the bugs in current one are fixed. Go to Play store> Settings and disable Auto upate apps over WiFi so that it won't update automatically. This resolves the issue and you can use other older version of google apps also like gmail, youtube which came preloaded with your phone.
2. Camera giving only 9.4Mega pixel Images: - I see by default the images clicked by this device is of 9.4 Mega pixel only. This happens because of the full screen mode being ON in camera. To resolve this> Open Camera app> click on setting icon> Full screen is highlighted by default just touch it to remove full screen mode. Congrats now your camera will click 13 Mega pixel images
3. Hard resetting your phone: - For users who wish to Hard reset there Alcatel One touch flash device do these things:
a. Power off your phone
b. Press and hold Power + Volume down button together until you see Android recovery screen. (Note: you need to hold these two buttons together until you come to recovery screen might take 20 seconds)
c. Now select "wipe cache"
d. Now select "Factory reset"
e. Now let the device reset your phone it will take some time around 1 minute
f. Now next time you power on it will stay at Alcatel boot image after sometime hold power button again to switch off
g. now hold power button and Congrats now your phone is resetted successfully
I haven't come across any other issue apart from these. Users who come across any other issue share in this forum I will assist in resolving the bugs, if any For those need screen shots to know the procedure let me know i will update screenshots of procedure in my next post.
People who wish to root their device a atip from my side is to wait for sometime until Alcatel officially provides stock image in their android upgrade firmware and only than try rooting as if at this stage if you screw up your device than it would be difficult to get the stock image and restore your phone.

Android Tablet Issue

Hello there. I'm making this thread today requesting some assistance on my new tablet. It's a pretty old one, I believe. Recently, My grandmother gave me her old tablet cause she got a new one, so I'm playing with it for awhile and nothing but ads keep popping up, it slows down. For the end of me, I can't even download an app to use as you would on a mobile phone or PC. I tried so many antiviruses and nothing worked except for ironically KingRoot's Purify app it told some apps that are malicious and said what it is which is admob. So here is the issue, I can't remove it, all the antiviruses suggest me to uninstall and when I do it's unsuccessful, for what reasons, I don't know. The only time I can basically do any kind of navigating and uninstalling the stuff is when the WiFi is off. I did uninstall what the anti-virus told me successfully with the WiFi off but when I turn it back on, it reinstalls all the apps all over again. So I narrowed the problem down to it being in the ROM or something. So my question here today is, is there anyway I can just like re-install the android operating system? Or as what many people call it, re-installing the ROM? And how can I do that? Below is my information I've collected from the tablet.
Model Number: Zeepad 9RK (that's all it says)
Android Version: 4.2.2 (Jelly Bean)
Kernal Version: 3.0.36+
Build Number: rk3028a-eng 4.2.2 jdq39 eng.dp.20140715.112011 test-keys
Serial Number: LZLGN4UWZQ

Help needed - I have an app which bricks my Samsung tablet when I try to install it

Now this is the weirdest thing I've ever encountered! I have a Samsung Galaxy Note 8.0 tablet (n5110) which runs TWRP recovery and Resurrection-Remix-5.7.4 (CM13 based). Everything used to work beautifully until the end of July when an app called “EPB DVR Manager” (in the Play store) received an update. My tablet had to do a whole bunch of updates, so I gave it the “go” and Play Store started doing its thing, updating one app after the other.
At some point the tablet froze. Dead. Even the clock in the status bar stopped. I had to reset the device by pressing and holding power until it rebooted. The next thing was ... boot loop. It seemed to finish the boot animation and at the point when the main screen is supposed to show up it rebooted!
Tried to wipe dalvik & cache. No go, still boot loop. Had to format data to get the device back to life. From there it took me quite some hours of repeated tries of restoring 100+ apps and crashing the device all over until I figured out that it was this specific app - the “EPB DVR Manager”. After figuring out that this app causes the problem, I did two more attempts to confirm what is going on:
First, I did a wipe of dalvik, cache & data, reboot, android setup wizard (setup Google account). Then, as the first action at all, I tried to install the “EPB DVR Manager”. Boom - device messed up again.
Second, I reverted back to stock firmware (kitkat) and installed the “EPB DVR Manager” - no problem at all. So it has something to do with the Resurrection-Remix ROM, but here's the thing:
I have 3 different devices (a Moto G 3rd Gen, a LG GPAD 7.0 and that Samsung Note 8.0) and all three of them run Resurrection-Remix 5.7.4 and the Samsung is the only device which all in a sudden has these catastrophic problems with the latest version of this app (earlier versions installed/updated fine).
Now I understand that my devices run different kernels with different hardware drivers despite all of them running RR-5.7.4.
I would really like to get a clue about what the heck is going on here. Now before y'all are telling me that RR-5.7.4 is dead because it is based on CM13 - I know that. Still, RR-5.7.4 is a way better daily driver than the newer Nougat builds. So how should I try to get “live logs” because the problem always ends in a crashed installation and Android needs a full wipe to recover. I would like to find out what is going on to be able to let the app developer know about the problem (if the app's apk is at least partially to blame).
Even if it turns out that it is RR's fault (and therefore the bug will not be fixed because RR-5.7.4 is dead) I would still want to learn how such a simple transaction like installing an app can cause such a dramatic (and 100% reproducible) crash of Android's data partition.
Thanks for any suggestions on how to catch logging information for this kind of mystery.
Markus.
