    After spending a few hours with the Lava Xtron+, I noticed that the battery was diving downwards at a ridiculous rate. This kind of usage was very strange, so I opened the battery stats page only to find that Cell standby had consumed nearly 65% of the battery. This tablet DOES NOT have any radio cells , even after turning on airplane mode it is consuming huge amount of battery, how to fix it?..Please read this review, this has addressed his issue

    It is a new tab should I replace it?
    OK, now after searching for a long time, there are many methods to fix it 2 of them require which I have to find a method and others like disabling phone and related apps and installing juice defender, doing it right now, will update !

    What did you expect from a cheap android tablet? All cheap android phones/tablets need to burn in hell. You are disrespecting yourself when buying such a thing.

    it looks err from your tablet itself, you may reset it and try to use battery saver and test it.
    you cant expect much but at least it will make your tablet last little bit longer

    there really isnt anything called quality android h/w tbh. everything is overpriced stuf which is basically china quality internals in a good looking chassis.


    firmware is bad. nothing to do here unless you can find a tablet firmware and flash it in and destroy the warranty.

    Oh man, I I rooted and renamed phone.apk and telephony.pak to *.bak and it is fixed...Battery is nearly doubled! Well there is not recovery available, but still I am not a complete noob after searching for 10 plus hours I have chosen this, rk3066 was according to me last gen's greatest chipset! Mali Quad core is slightly faster than tegra 3, and the only possible |con| other than battery life is unsupported games and immense lack of developing community (still, better than others)..One more thing, I am not able to find a recovery, (well, I know that it hasn't been ported by cwm), and the only rom available is riley rom, there is no way in hell I'm going to flash a non xda rom which doesn't even have working wifi

    Here is my review on flipkart..
    | HARDWARE |:-: Talking about the Lava Xtron+’s hardware, the tablet boasts a dual core Cortex A9 CPU with each core clocked at 1.5Ghz and a Mali 400 Quad Core GPU.
    Well, for the proof of graphics power, see the most helpful review here ,63.9 fps in nenamark, and the most important thing according to me, RK3066 IS THE BEST LAST GEN GAMING CHIPSET BETTER THAN TEGRA 3...I am a true geek and after searching for 20+ hours came to a conclusion that this is the best piece of android till 12-13k,(except Lumia 520 but it is windows)..

    | BATTERY | :-:Coming on to battery, When I opened the battery stats page I find that Cell standby had consumed nearly 60% of the battery.WHAT!? Cell standby is the battery used by radio cells for mobile networks. This tablet DOES NOT have cell radio! The engineers working on this tablet didn't even bother to setup the OS properly and instead chose to simply download Android 4.2, flashed it in the tablet and have put it up on sale.
    The Flipkart page reports the battery capacity to be 3,700mAh, which is probably wrong since the official specifications page on Lava’s website reports it to be only 3,000mAh. I can't be sure..

    AIRPLANE MODE IS NOT COMPLETELY WORKING DUE TO DEFECTIVE DRIVERS (CELL RADIO DRIVERS ARE PRESENT IN THIS TAB SO IT SEARCHES FOR DRIVERS CONTINUOUSLY AND FUC*S BATTERY UP!)

    | SCREEN |:-:The front of the Lava Xtron+ holds a 7-inch sharp IPS LCD display having a resolution of 1024 x 600. It’s a bright screen and with a pixel density of 170 PPI, it is pretty sharp too. The best part about the display is that, despite being an LCD screen, it’s not a battery consuming monster. I always found its battery usage to be lower than processes. The screen is prone to scratches though and is highly reflective.

    NOW THE MOST IMPORTANT THING HERE ROOTING (one more time) ROOTING!
    Here is the method tested by me...
    First of all , I am not responsible if it bricks your device.(Don't come complaining if it does!)

    1) Install moborobo and it will download the required drivers for you.
    2)In your tablet go to in Settings , find developers option and turn it on and enable USB Debugging.
    3)Before connecting it to your PC( it works only windows ) go into the tab's settings again and click on storage.In it you will find 3 dots in top right hand corner.Click on it and USB computer connection will be there.In it select the storage to Mass storage.
    4)Connect it to your PC and let moborobo download the drivers.
    5)Now install the software from the attached file given in this post.
    6)It is a Chinese software so click yes on all prompts during installation.
    7)after it is installed it will open.
    8)wait for it to detect your device and then there will be a window on the right hand side showing the statistics of your device.
    9)in last statistic it should look like this: Root?? ON>>nE .
    10)then click on option ??Root.T
    11)It will have a prompt showing a tick mark in the center and 3 rectangles below of the colour of blue , red and green.Click on the green box.
    12)Then the tool will start its work.DO NOT INTERRUPT ANYTHING AND CLICK YES( green colour means yes ) TO EVERY PROMP IF IT ASKS YOU.
    13)It will restart your device and an app called superuser will be pre-installed.I recommend you downloading another superuser.
    14)Download root checker to check whether the root was successful or not.

    Worked on my LAVA ETAB XTRON+
    Note: DO not turn on usb mass storage (when connected to pc)connection.
    Note:Remove your external SD card before rooting.
    Note:If your device detects Nand flash as sd card then no need to disconnect it.

    and now how to fix battery:-:

    Get root explorer open system/app and rename phone .apk and telephonesomething.apk to phone.bak and telephonysomething.bak, you are good to go..

    I had waited and checked price for everyday for the past month and bought when the price got to 5000, now, value is unbearable, polish, hardware, battery and everything is so awesome it almost brought me to tears of joy!
    the only con that I could find is that less games are supported than Tegra 3 still, next gen games should be supported most probably..

    EDIT: OTG cable works with pendrives (don't have external hdd), and there is no way of getting official USB drivers I am not even able to set "ADB" up, and charger is last gen..but I don't have a problem with it as long as it doesn't create any problems, Just checked Wifi, works flawlessly |note|: is it my first use of wifi so no comparison..OMG I left one thing out We can enable the biggest part of pc gaming in android nnow, i.e 4xMSAA in settings
