[G Pad 8.3 Q&A, Help & Troubleshooting] Kaiyo Droid:
Greetings xda :)

I just purchased a secondhand/used/pre-owned Verizon model LG G Pad 8.3 (vk810) on ebay and have noticed that sinnce day one that I've had it (maybe 4 days?), that overall performance is pretty inconsistent. Sometimes it flies through the UI with impressive ease and other times it seems bogged down simply running Chrome with a single tab open and hitting the Home button.

First thing I did when it arrived was run some benchmarks. I noticed that across the board I was receiving results that were roughly 40-50% lower than all the charts I've seeen others posting online, including proffessional reviewers' articles.

I cannot recall *all* the scores for each of the different programs, but for instance in Antutu it seems everyone else is hitting 25000+, whereas my device is sitting at around 15000 or so. I did this on stock 4.2.2, 4.4.2, rooted, unrooted, fresh stock rom flash, with TWRP and without, and each time it's been the same outcome. Antutu reports all the same hardware everyone else's does, yet this. I'm fairly certain it wasn't some kind of bait and switch for a knockoff or inferior tablet.

When gaming, most of the stuff I play runs decent enough, with some stutter here and there, albiet they are not all demanding games (from Hay Day, to Walking Dead, to CoD: Strike Team and everything in between), but I've still been noticing more overall chug factor than the specs of this tablet should be delivering all day with ease. I started to worry something was wrong when I was strugging to run GTA: San Andreas on Medium. When I look at say the Antutu example again, other people's G Pad 8.3 rank shy of a Galaxy S4, where on mine I'.m getting beat our by the Galaxy S III.

The tablet doesn't appear to be overheating, causing throttling; but I just can't seem to wrap my head around it or even know where to begin troubleshooting other than coming here and asking for assistance. If someone could possibly be so kind enough, any thoughts on how I should proceed in troubleshooting this? Thanks in advance!

The Verizon 8.3/VK810 is only clocked at 1.5GHz vs the 1.7GHz of the V500/510.
[G Pad 8.3 Q&A, Help & Troubleshooting] Kaiyo Droid:
Interesting... Thanks for the info, Planterz :) Wasn't aware of that.

I'm certainly no expert when it comes to CPU's, especially in the mobile world. Would a mere 200Mhz per core difference in clock speed provide such disparaging results among otherwise identical hardware?
[G Pad 8.3 Q&A, Help & Troubleshooting] Fullmetal Jun:
15 000 antutu is in range of s3, I think, which has inferior hardware! You should have scored easily over 21-22000 with this beast's snapdragon 600 no matter even with a 200mhz difference! Charge the battery to full, switch off for about 2 hours, boot, standby for about 1 hour and check again! If still under 20 000, something is wrong with device and you should change it!!
[G Pad 8.3 Q&A, Help & Troubleshooting] Planterz:
I only get around 20000 on my V500, but I'm still running stock (rooted) 4.2.2. I am about to finally updated to 4.4 and flash the updated Dalvik and Qualcomm binaries though.

I don't know why Verizon's version is only clocked at 1.5GHz, when the SD600 is clearly capable of much more (the Galaxy S4 has the SD600 clocked to 1.9GHz). Maybe they saved a few bucks by going with a lower bin, or maybe it's just underclocked to stretch out the battery life. 200MHz across 4 cores definitely makes a difference in benchmarks, especially with the amount of pixels they have to push on the 8.3 (1920x1200 makes it 1200p, not the standard 1080p of FHD). The Galaxy S3 might get 15000 in Antutu, but it also has less than half the pixels to push. My Galaxy Light, which is NOT a high performance device, also gets 15000-16000, but it has less than half the pixels of the S3. Remember, benchmarks aren't always an indicator of real-world performance.

EDIT: I haven't used the Verizon 8.3, but being a Verizon device, I imagine it's chocked full of the typical Verizon bloat. Check your processes to see if there's something unnecessary running in the background and delete that crap, or at least disable or Greenify it.
[G Pad 8.3 Q&A, Help & Troubleshooting] Kaiyo Droid:
Good stuff here... Thanks!

Yeah, honestly I typically don't depend on benchmarks, but like to refer to them as a ballpark figure of sorts. For instance, on PC, I typically wouldn't be able to tell a single difference in terms of actual, real worl performance when comparing say 3 Ghz quad vs a 3.2 Ghz quad. But synthetic benchmarks might show one edging the other out by a significant enough margin to make it worth mentioning.

I ran Antutu on my Moto G - a 1.2 Ghz quad core Snapdragon 400 - and pulled like ~16600, but only got ¬15700 on the 1.5 Ghz quad core Snapdragon 600 found in the G Pad. Could be a software bug perhaps too. I also flashed the June 2014 Adreno drivers, but it hasn't seemed to make a difference in how this thing is scoring.

Edit: Okay, weird. Both Antutu & CPU-Z are reporting that I have a 8064 Snapdragon S4 Pro... NOT the 8064T Snapdragon 600. Would explain a lot. Spec sheets show the G Pad (presumably the V500/V510) having the 600. I used a hardware identifier app, but it reports I have the Snapdragon 600 on 8064 board. Now I'm wonderin if the VK810 ships with an S4 Pro instead of the 600 like the V500V510.
[G Pad 8.3 Q&A, Help & Troubleshooting] Planterz:
Remember that the Moto G has less than half the pixels to drive than the VK810, so it takes less processing power to keep the framerates up and thus score well on the benchmarks. 3D games run far smoother (and with higher detail settings) on my Nexus 4 than on my 8.3 V500, most likely because of this same thing.

Still, your scores do seem low, and I would have expected the optimized binaries to improve things. If you look at this thread, others with the VK810 have been getting 19-20000 scores, although they also report some choppiness. I guess itt's possible you got a bum unit.
[G Pad 8.3 Q&A, Help & Troubleshooting] Kaiyo Droid:
Thanks! I think I'm beginning to understand the difference in needing to push more pixels now.

Came across this thread too regarding someone's trouble identifying the CPU on their LG device using CPU-Z and Antutu: http://xdaforums.com/showthread.php?t=2341947&page=2
[G Pad 8.3 Q&A, Help & Troubleshooting] Planterz:
What does CPU-Z say your VK810 has? I've looked around and can't find specifics on this anywhere that I can be sure of. Both LG and Verizon merely list it as a "1.5 GHz Quad-Core Processor, Qualcomm® Snapdragon™ Chipset". There's other sites that state that it's a Snapdragon 600, but this could just be an assumption they made because the V500/510 have the S600.

According to wikipedia, The S600 is sometimes marketed as an S4 pro. The Nexus 7 (2013) for example, is advertised as having an S4 Pro, but apparently it's actually in the S600 series. On my V500, CPU-Z gives me a model number of APQ8064T. If CPU-Z gives you a model number, you might be able to track down exactly what it has on the wikipedia page I linked to.
[G Pad 8.3 Q&A, Help & Troubleshooting] Kaiyo Droid:
As you stated, many of the places that list specs for the LTE model of the G Pad 8.3 simply mirror the ones found for the V500/V510; incorrectly specifying the SoC as the S600 clocked at 1.7Ghz (which we know isn't true). Probably simply assumed they would be the same, only one would feature LTE connectivity.

http://pdadb.net/index.php?m=specs&id=5693&c=lg_vk810_g_pad_8.3_4g_lte

http://www.phonearena.com/phones/LG-G-Pad-8.3_id8141 (scroll to the bottom under Variants)

CPU-Z reports that my VK810 has an S4 Pro, APQ8064. However, the hardware identifier app states it's an S600 clocked @ 1.5 Ghz, APQ8064"T". The Antutu Benchmark and Tester apps also say it's the APQ9064T clocked @ 1.5Ghz. Maybe it's a software side miscalculation with CpU-Z, yet it still doesn't explain why CPU-Z can properly identify the S600 in V500/V510's, but not the VK810.

Qualcomm's own website for the Snapdragon 600 specifically cites the LG G Pad 8.3 LTE (VK810) as having the S600 APQ8064T under the hood (as well as the Galaxy S4 and HTC One). Oddly, the V500/V510 aren't listed on that page, only the LTE variant. Link: http://www.qualcomm.com/snapdragon/processors/600

I used SetCPU to change the govenor from On Demand to Performance, ran Antutu twice and scored ~18800 both times. I haven't tried disabling thermal throttling, because frankly, I haven't been able to find out how.

Now to figure out why my unit is benching well below other users' VK810's.
[G Pad 8.3 Q&A, Help & Troubleshooting] Kaiyo Droid:
Fixed! (Well, somewhat...)

So, here's what I ended up doing:

I am on 4.4.2, rooted.

I unistalled SetCPU, and installed the "Trickster MOD Kernel Settings" app (Google Play: https://play.google.com/store/apps/details?id=com.bigeyes0x0.trickstermod&hl=en )

In Trickster MOD, I did the following:

Under the General menu, I set the governor to "Interactive".

Under the Specific Menu, I changed the following:

Temperature Throttle = On (default is OFF)

GPU Governor = On Demand or Performance (either one seemed to work, default is On Demand)

GPU Max Frequency = 400 (default on mine was 320 for some reason)

Once you set everything up, reboot the tablet.

Recall that in the beginning, with no tweaks, I was scoring around 16000 in Antutu Benchmark.

With these minor tweaks, I've benchmarked it several times and now consistently score between 21000 to 22000 in Antutu.

Not sure if this is of any use.

Not quite sure if you will get coverage on your new phone when changing networks ? this is possibly usefull to you.

It's just a link fron the UK OFCOM web site. You can tell what mast is belonging to which operator and even power levels.. You can find out if your new 3G phone will actually work....

Very handy and fairly accurate from what I have checked so far whilst working away around the UK....

I just got a new Tmobile S5. SM-G900T is the model number

Was looking to confirm if this is the correct twrp for my device http://teamw.in/project/twrp2/229

When I used GooManager it said that it could not find a recovery for my device, but see where folks have mentioned that they had a little trouble with goo manager.

I've searched and this is the only version that I am finding for the LTE Tmobile devices.

As an aside to that, if I dl the tar for use with Odin, will this wipe the device if I choose to install it?

T-Mobile Specific Section: http://xdaforums.com/tmobile-galaxy-s5

Flashing any unoffical non-Samsung recovery will trip your Knox warranty flag, making it void and it cannot be reset. What that means to you personally, I don't know.

Flashing any recovery via ODIN will not wipe your phone.

edit: I don't know much of anything about TWRP. I prefer Philz CWM Touch Recovery @ this thread: http://xdaforums.com/showthread.php?t=2201860

For recoveries, you just need the KLTE version. That's the family our phone (G900T) is in.
[T-Mobile Samsung Galaxy S 5] microm3gas:
Thanks very much for your reponse, that version I posted is Labeled KLTE. From what I was finding last night that is what seemed to be correct, I just like measure twice and cut once....

I looked briefly at Philz last night. I switched from CWM to TWRP a bit ago and am just realy familiar with it. I could change if necessary, but it's like second nature to use now. That is the thread I glanced at last night, I will check it out more thoroughly to see if it is for me.
[T-Mobile Samsung Galaxy S 5] microm3gas:
I flashed that Tar file and dont see any obvious issues. TWRP yay.
[T-Mobile Samsung Galaxy Note 3] Rich3077:
Just picked up a new Note 3 and root is required to run an app that is critical to me.

I was just about to root and then call and cancel my insurance.. then I started noticing threads where people have claimed root on 4.4.2 without tripping the Knox flag.

This is a new phone, never before rooted. I do own Mobile Oden Pro and Triangle away and am willing to purchase other apps if needed.

Either way this phone will be rooted but I would like to keep my insurance warranty if possible.

Thanks

Edit.. custom recovery would be an added bonus not is not needed.
[T-Mobile Samsung Galaxy Note 3] Misterjunky:
re: rooting

If your baseband is NB4 or NE6 you can use "Towelroot" for rooting

otherwise if your baseband is NF1 or NF4 Towelroot will not work.

Towelroot will not trip knox.

If you flash any custom recovery knox will get triggered

but so far no one lost their warranty due to triggering knox.

Without custom recovery you will not be able to flash any

custom roms.

Good luck!
[T-Mobile Samsung Galaxy Note 3] toastido:
You can use your insurance even with knox tripping. It only voids your samsung warranty, not your insurance. Just an fyi.

either way you pay one 175 for a new note or screen fix we so i dont matter if you damage the phone or the system

I'm rooted and have made a have few changes to my phone in general, but now it won't start up. It gets past the LG logo but then gets stuck at a black screen with the LED's cycling colours.

I've tried to factory reset it but it still gets stuck at the black screen. How do I fix this?
[G3 Q&A, Help & Troubleshooting] saitch76:
I has this a few days ago.

To fix it you will need LG mobile drivers and LG PC Suite installed.

Power off your G3. Then start it in download mode by holding the volume down button and connect a USB cable to your phone. The screen should show download mode. Connect your phone to your computer and start LG PC Suite. Don't worry if PC Suite doesn't recognise your G3. Go to the mobile device menu and select restore upgrade errors. PC Suite should download the latest firmware and install it. You will be back to a factory reset but your G3 will be working again ☺

[G3 Q&A, Help & Troubleshooting] jamespat93:
Thanks, Ill check that link out.

I'm finally on a PC and went into download mode but now my phones stuck at 0% doing a firmware update. It says don't disconnect the USB until the process is complete but I think I'm going to have to :(

When I did click fix software errors it said there were no errors to fix but I don't think I have all the drivers installed yet.

When I try go to download mode it keeps taking me to the firmware update screen and stays at 0%. Also the drivers aren't fully installing on this computer for some reason.
[G3 Q&A, Help & Troubleshooting] saitch76:
Install the LG united mobile driver first then LG PC Suite. Might be useful to reboot the Windows machine after that. Try having PC Suite running when you connect your G3. PC Suite might nag you about being unable to connect to your G3. Just cancel that and select restore upgrade errors. PC Suite should download the latest firmware before it flashes it to your phone. Check that your G3 is in download mode before you connect it to the Windows machine.

I'm assuming you've checked obvious things like turning off any firewall software that might block outgoing connections...

There are drivers and PC Suite for Mac on the LG website. That was all I needed to recover my G3 on my PC. I would try installing the unified drivers and PC Suite again. Start up PC Suite. Put your G3 in download mode and connect it to your Mac.

If that doesn't work and the unified drivers and PC Suite won't install on your friends Windows machine then I would run chkdsk and the system file checker.
