Troubleshooting : Play store download speed super slow all of a sudden - G3 Q&A, Help & Troubleshooting

Device is a F460s (a.k.a the LG G3 Cat.6 / LTE-A version with the Snapdragon 805) currently running Mokee ROM. Was running RR 5.7.0 by JZ_shminer until today.
So basically, here's the summary of the problem. When I'm downloading very large apps / games (1GB+) over WiFi from the Play Store (N.O.V.A 3 for example), the first 30 seconds or so of the download goes as expected with speeds that are close to nearly maxing out my 100mbps connection. Unfortunately, after the initial 30 seconds of 10MB/s glory, (the time that it takes for the download speed to "throttle" actually varies quite a bit, usually the first runs last for around 30-40 seconds at 10MB/s while immediately starting the download after cancelling a download that was already being "throttled" only lasts for around 10 seconds before being "throttled" again) the speed suddenly drops to around 500KB/s for no apparent reason and stays there for the rest of the download. At first, I was pretty sure that it would be an easy fix related to some network setting I messed around with accidentally, so it was rather concerning when I saw a network settings reset didn't do anything. After resetting the network settings multiple times in hopes that it would eventually fix itself, I carried out a few basic tests to try to pinpoint the problem. Here were the tests that I did : Multiple speedtests of my connection using both the Speedtest.net Ookla app and the traditional website through chrome to confirm that the issue is only present in the Play Store (Although I will say that the speeds were rather unstable using the app, too bad they were still more than 10x of what I was getting after being "throttled" in the Play store), downloading the same app using several different phones (they were all pegged at 10MB/s, all of them), doing the same thing with AdGuard disabled (made 0 difference, thought maybe the local VPN did something), repeating all of above while using a VPN, doing a full wipe, and even installing a new ROM when that didn't work. Something that I did find intriguing though, is that using a VPN while downloading (Not turning off AdGuard, just using a third-party VPN app), got me rather surprising results. While my initial "starting" speed (basically the first 30 seconds) with a VPN was around 1/3 of what the non-VPN run would get in the first few seconds, it could sustain that 3-4MB/s for the rest of the download. All 1.3GBs of it. Would this indicate that this "download speed being throttled in the Play Store under specific circumstances" thing is a software-side issue? But if that was the case, why would installing a new ROM make absolutely no difference? Haven't tried stock MM yet though, planning to do it tomorrow to see if that makes any difference.
Also, a few things to note that could potentially help determine whether it's a hardware or a software problem : Yesterday, I finally got around to applying the dbrand skin that I bought for this phone a few weeks ago, and in the process, used a hair dryer to heat up the camera / volume and power button area for around 30 seconds to ensure a more optimal fit. Could this have damaged something inside the phone that has an impact on sustained download speeds? Personally, it seems rather unlikely, considering that it was done with the battery removed and dbrand recommends a heat gun to do the same thing.
There's also this more-likely scenario : When I woke up this morning, I immediately grabbed my phone next to me to check the time, only to find out that it was bootlooping. To be specific, it was the kind of bootloop that you encountered when you had a faulty battery, or at least I'm assuming it is because I had the exact same thing happen because of a faulty battery. The phone was also SUPER hot when I initially picked it up and no button combination seemed to able to get it out of the bootloop, so I had to peel off my poor literally-just-applied-the-day-before dbrand skin in order to remove the battery and cool it down. After a few minutes of leaving the phone to cool down by itself, I inserted the battery back in and to my surprise, everything seemed to be in working order. There were no signs of any sort (until now that is) that indicated anything was wrong with the phone, so naturally, I assumed it was fine and chalked it up to my very stupid and dangerous habit of "leaving the phone in bed while fast-charging with a third party Quick Charger" which led to the phone overheating to the point of forced shutdown and reboot, only to fail to do so repeatedly...? I don't know if that even made any sense, as one would assume that a phone reaching highly dangerous temps would shut itself off and STAY off in order to actually prevent any damage being done to the components. I don't know much about this stuff though.
tl;dr : Phone is getting painfully slow download speeds all of a sudden and it's not my connection, 99% sure. Not sure if hardware or software problem. Leaning more towards hardware atm. Although I'm not sure how that would be possible. It would be great if you read through the whole thing, as there is quite a bit of info, but really any help would be greatly appreciated.

[Q] EVO random restarts when multitasking GPS/voice - Sprint knows of this issue

I have noticed that when I am using my EVO in the car for GPS + bluetooth + charging, it can get quite warm. Especially when its sitting in direct sun. Several times now while it's sitting in my cup holder it has started blinking the LED rapidly. I checked the battery temp in the battery app I run and it was approaching 50 degrees Celsius. What is a reasonable cut off temp that I can set an audible warning with so I notice next time it starts getting really hot? 49C ? What is considered the point where an EVO is "too hot"?
Also, on a potentially related note, the EVO will often crash and restart when I'm using GPS + voice communication (on a call) + BT + charging. This seems to be the required combination of multi-tasking to replicate the restart. I do this a LOT in my car with work so I have easily replicated it several times. I called Sprint and talked with advanced tech support. Once I described the specific problem he essentially offered to send a replacement phone with almost no resistance. This led me to believe its potentially a common/known issue internally at Sprint. Once I said a few magic words (voice and GPS simultaneously), he seemed to acknowledge it was a valid issue he had some experience seeing. They replaced a 0003 unit with a hardware version 0004 unit. Unfortunately, the issue still occurs. However, it doesn't seem to necessarily be heat related as the phone isn't always hot when it happens and I don't get rapid LED lights like when it has gotten really hot. All battery use has been the normal stock battery in both hardware versions.
Background info:
For testing purposes I am using stock Sprint rom fully updated, rooted. All standard radio/kernal, etc. No overclocking or anything like that.
I do all those Multitasking things all the time. It has never crashed/rebooted, in fact I don't recall ever having a random reboot.
I rarely have it in direct sunlight, I use a ProClip most of the time (which does allow a lot of air all around it).
It does get warm doing GPS, Charging and BT Voice Call. And it barely keeps up charging while GPS Navigation is going.
It might be your charger is allowing it to charge faster than it can handle.
I run MikGinger now and ran NonSense ROM for while.
My BT is always a little flakey though. If I make a call, hang up and wait and make another voice dial call it will all work fine. If I hang up and immediately make another call the phone will disconnect headset and leave Voice Prompt on Screen. If I clear screen and click headset again it reconnects fine and all is good. Every ROM has done this including CM7, Stock and Leaked based ones.
I had this same issue on my original phone. Doing anything in the car while it charged caused it to reboot. Even after being off and cooling down, I could get it to reboot by quickly scrolling up and down in the browser. My phone would just get warmer and warmer, then reboot.
I got them to give me a replacement, and all has been fine after that. It's a white Evo, HW rev 0004. I'd recommend getting another replacement. You shouldn't have to sacrifice doing what you want in order to keep your phone running. I can now have my phone charging on a hot day while getting GPS instructions and listening to Pandora. I don't have any bluetooth stuff, but I imagine I could do that as well.

[Q]Known problems of LG G3

I am thinking about buying a new G3, Is there any chronical issues-problems of LG G3?
Like dust in screen or speaker blow or any hardware malfunction
Don't be completly discouraged when reading this, as this is just my list of CONs for this phone.
Here's some of the issues i've had on my G3 from the very minute my phone left the box:
1. The phone has a locked bootloader, So don't expect any custom roms or kernels anytime soon.
2. This phone gets very hot for almost no explainable reason all the time doing small tasks like browsing the web.
3. WiFi (and maby LTE??) are REALLY slow in comparison to every other phone i've owned in recent years (sometimes web pages even freeze while loading).
4. The stock web browser kills my battery in about 2-3 hours from a full charge on 0% brightness because of LGs stock webbrowser sandbox security.
5. I get constant "connection timed out" errors while trying to stream many online videos using the stock web browser.
6. CPU doesn't hit max speed on this device without messing with thermal options.
7. The phone is very laggy & slow on my version (10b), I don't know how other versions are though.
8. The glass started falling out of my first G3 (around the edges) and i had to exchange for a new one because of this. (my new one did this too but only at the bottom and i just live with it)
9. VERY poor color & contrast when the screen brightness is turned way up (looks good at low brightness though).
10. My left headphone buzzes while the CPU is under load while no audio is playing, Once the CPU load stops or once a song or movie starts playing the buzzing stops (tested with 2 sets of headphones, both buzz but apparently some other users say there are headphones that don't do this).
11. + some other small things.
Probly the most complained about things are these:
1. lag
2. overheating
3. physical cracks develop usually around the ir blaster or mic
Im not having any lag issues, im on 10i though, my phone is yet to get hot too, not sure why this is, im very very happy with mine at this stage, only downside is the locked bootloader.
No issues here, the heat issue was fixed with software updates from what I have seen. I have no issues with heat on mine. The contrast can be fixed or made a little better in the accessibility menu. I've had 3 G3's and none of them had the screen fall out or develop a crack around the frame. (I think that was a limited issue)
I bought my first G3 back in early June and it was fine until I dropped it off my balcony. My Att G3 hasn't had any issues either. The signal issue listed above is more of s perception thing. My F460S (G3 Prime) only has 4 bars in its cell service instead of 5-6 that others have. So basically if I have 3 bars its like having 4-5 and my connection has always been fine. I think that some of the issues are exaggerated on this phone but that's just from what I have seen after owning a G3 since it launched more or less.
No lag, no heating.. Just two troubles.. 1.LG software.. Phone is so slow and heavy. 2. Locked bootloader..no LG software replacement.
If you want a g3 with an unlocked bootloader, buy it from T-Mobile. I have mine rooted recoveried, and have installed a very nice custom rom/kernel. This is by far my favorite Android yet.
As far as Amb669's list goes we haven't seen any of those problems. My wife and I have had our Verizon G3's for a couple of weeks now (not exactly a long time) with zero issues.
My WiFi speed in particular is Amazing.
Keep in mind two very important caveats:
My wife and I almost certainly use our G3's differently than Amb669 (and each other) - not better or worse just different.
It's possible that if we used our G3's in the same way as Amb669 does we might experience similar problems.
Our G3's were purchased recently - our phones may be from a later batch that has had issues corrected.
Our G3's firmware/software could also be different/improved.
I LOVE this phone and wouldn't hesitate to recommend it to others.
I have some problems with my G3 too, it's too slow... i prefer my Old Xperia ZQ, maybe it's a Software Problem ? and my G3 gets so hot too... damit i'm disappointed.. there are something that could do ?? i already resete it but still the same thing.

I have not encountered ANY of these issues, except for the heat issue.. But seriously it doesn't get that hot? Mine gets to about 55 degrees Celcius and that's max.. (I have the int. Version though)
On the other hand I do agree on the fact that the colours could be better on high brightness but hey, it's not a Samsung AMOLED display like the S5
For me the LG G3 is a stylish, fast, and amazing phone that offers everything I need :good:

tab gets flickering screen and reboots

I dropped by tablet battery down once and now every so often the screen flickers with vertical lines and this is followed by loss of network and the thing reboots.
I've read this to be a battery problem.
Warranty is still active but I've rooted it and my Knox counter has gone up.
What do you think XDA? Just get a replacement battery?

If you have the ability, since it was dropped, I would open it and make sure connection is tight to battery and screen. Then if it still acts up, get a battery. Several people had battery issues out of the box. All it turned out to be for a few was a loose connection.
i was thinking about that but i'm afraid of voiding warranty. do i even still have warranty? due to the knox?

Well ive opened it up and tightened everything i can see and it seems to work ok for a while, when the charge gets to around 20-30%, the tablet flickers, all mobile connections are lost and 75% of the time, reboots.
So i went ahead and got a new battery. Now this was worse kinda. At random moments, like unlocking the screen, or replying to a message, or maybe just a high cpu load event, the tablet just turns off and is unable to be powered back on without first connecting it to a power supply like a wall charger or a power bank.
The time and date will be reset once its back on and ill have to wait a few minutes before the auto network time setting kicks in before i can use something like whatsapp.
Anyone got any clue what might be causing this problem? Thanks in advance, helpful xdarians.

I'm not by any means an expert or repairman of any kind, just so you know. I'm thinking maybe a loose connection at the terminals on the board the battery connects to or if they use a separate board for the battery to connect to and then to the main board it may be somewhere along in there. Maybe a loose wire going into the tab that connects to the prongs. It sure sounds like something isn't making a good connection. Sounds like a load gets put on it and it and that bad connection can't handle the load.
Might just be you're going to have to send it off...
You may be right. Sounds like a particular connection which does higher load or something. Once i put the tablet in power save mode, the symptoms never reappeared. I dont notice a drastic slowdown in the tablet either. Probably am prolonging the inevitable.
Same Symptoms

I am facing exactly same issue what you have described and am in same situation, have tripped Knox on my Tab S 8.4.
I can see that you have been able to suppress the behavior by putting it to Power Saving mode. Have you experienced flicker and reboot since then? I am planning to take it to Samsung store not sure if they will honor warranty, did you tried that?

nope, ever since the Power Saving mode solution, it hasnt flickered and rebooted yet. and my warranty was expired by that point so i didnt bring it to the shop. no noticable reduction in performance so far

I have seen this problems on 2 tablets 10.5 and 8.4 the connector where battery is connected on motherboard gets loose which causes reboots and flicker
Solution in my case was resoldering that connector again
i had the same problem, opened up my tablet, just disconnected the battery, cleaned the contacts, pushed it back, made sure its nice and snug, put it all back together and now battery doesn't drain as fast, no more flickers and reboots!
hmm. i'll have to give it a try. you think this may be something to do with condensation?
Sorry for the bump, but I'm having this issue as well on my S 8.4. Custom ROM. The thing with me is that it's not consistent. One day, it will do it a few times; others, no issues whatsoever. I'll try the suggested if it gets progressively worse.
Hey guys,
Unfortunately our home's tablet (Tab s 8.4 Wifi) has the same problem.
It never did weird whatshowever, but when I flashed a custom rom (which went perfectly smooth actually) the screen flashes and the tablet reboots sometimes.
Now it weird that this never happened before and only when I flashed a custom rom it began showing this behaviour.
I am affraid of opening this tablet, and I guess because of the custom rom there is no warranty left anymore (or can this be bypassed by some terminal trick?)
Also I question myself if this is not a software issue, and that it can be fixed with software or so?
Thanks for answering!
My Fix
Hey Guys!
I might have some surprising news to tell about this "issue".
I saw some unboxing video's and saw at what place the battery connector was placed. It was some sort of a 'push to click' system.
So what I did was the following:
I pushed the tablet at the place of the battery connector. I tried this at various places until I heard a *click*.
Now I don't have this issue anymore. Jay!
I hope this will help you too!
I started to have the same issue on a Tab Pro 12.2, presumably after the battery has lost considerable amount of its energy. Normally I remember this tablet to have a dazzling 10+ hours of usage time. Just after some serious usage time of more than 2 years this issue started, along with increasing temperature and finally reboot. From time to time Android gave a warning message about overheating. From time to time charge values drop big values at a time. From 45 to 20 or 80 to 50. Seems arbitrary. This was happening even when I was on stock, then I switched to some Android 6 stock port from some other tablet. Still the same.
I believe the battery needs replacement. (That's obvious after 18 months, I just mean blinking is related to this) Hope I can find a high quality one cause there are several garbage batteries.

[Q] T-Mobile H811 (Brown Leather) get's awfully hot!!

Anyone experiencing a very hot phone with the new G4? I thought that they chose the 808 vs the 810 because of heat problems, but when I have Tune-in running in the background or Google Play is updating 6 apps, the phone gets extremely hot. I just got a warning that it was 51c/123F. That's quite hot for doing so little. Nothing else was going on.
Anyone else experiencing this issue?
that sounds concerning... probably yet another defective G4. I haven't seen a temp over 105 on mine
I've noticed it getting very hot in my pocket. I've only noticed this a handful of times with my previous phones (G3, G2, SG4, SG3, SG2, etc), but it's happened quite a bit in the week that I've had the G4.
Mine feels as cool as a dead cow.
Sent from my LG-H811 using Tapatalk
Most of the time, mine is too, but if it does anything slightly intensive (I don't think updating apps or playing tune-in radio as intensive), I get warnings about battery temps and it feels very hot right around the buttons/camera and on the glass side. There are times, when it's just sitting in my pocket and I can feel how hot it is. It's not burn-the-skin hot, but it's uncomfortable to keep in my pocket. Normally, battery temp in the high 80s low 90s, but at these times it's registering over 100F.

I use TuneIn regularly, also Google maps when driving, and I haven't noticed any increase on temperature at all, not even when charging.
Mine is always cool as a dead cow too, LMAO!
I tweeted t-mobile help to see what they have to say.
Mine hasn't even gotten remotely warm, even if I play with it while plugged in.
Nope.

Mine got warm inmy pocket next to my wallet out in 105 degree weather...not hot but warm
I have the same issue. Gets really hot just from simple things like web browsing and games that are not graphic intense
I told T-Mobile and they keep saying that I'm running too many things in the background. I've used this phone the exact same as I used G3 and it never got hot like that. The only time it would get hot would be in the car with tune-in + gps + charging was going on.
I have had it get hot in my pocket too. So hot i needed to move it to a different place. Not sure what was causing it but i hope someone figures it out..
Same here. Not sure what to do since some say theirs doesn't get hot and some say they do.
So I took my phone to T-mobile today and they first went through "your phone is hot for idiots," telling me that running too many apps, leaving it out in the sun, using a case, playing games, etc, can cause the phone to get hot. I told them that it got hot when the play store updates apps. She said she could fix that and turned of auto update. Really? I showed her the current temp of 81F. I then turned on Tune-in Radio and made a phone call. In the matter of 7 minutes, the temp wen from 81F to 96F. Still okay. I turned off Tune-in Radio and hung up the phone and then turned on Periscope. The temps raced to 109F. The buttons were hot to the touch and my batter app warned me about the battery being too hot.
They told me it was too soon for the warranty. Really, too soon? And because I was in the buyer's remorse period, that since I bought it online, I would have to return the phone online and once they received the phone, they would send me out another one. What? They said I would be 7-10 days without a phone because they only ship ground, not overnight. The representative in the store offered me a loaner phone which was a flip phone circa 2002. I told her that was unacceptable. If I purchased it from T-mobile online, it should be just as if I purchased it at a local store. I can buy on Bestbuy.com and return to the local store. They said no. She talked to her manager who then told her to complain on the phone and after about 45 minutes, she got them to send me a new phone (5-7 days) and then when I receive it, I can ship back my too-hot phone.
The manager didn't think that 109F or 117F temps were too bad. I told him, that these were the temperatures that dangerous battery malfunctions are made of. I had a battery that bulged almost to the point of breakage on my Sprint PPC 6600 back in 2009.
So hopefully, this will resolve my problems. I'm supposed to get the LG second battery on Saturday. I'll swap batteries to see if it is just the battery.
Oh, I also forgot to mention that T-Mobile twitter told me to restore my phone to stock, out-of-the box state. Don't log in using my gmail credentials and leave the phone in the default stage for a few days to see if it happens again. Really? What's the point of having a smart phone if all you can do is text and receive calls? Without gmail credentials, I can't download apps, I can't check my email, or do anything else you're supposed to do with a smart phone. Of course texting and cell phone alone shouldn't tax a smart phone. Duh!
Frustrated, to say the least.
Did they require a receipt ? I am thinking of getting a replacement. i have a leather g4 that overheats and when it gets hot around 105f it is unusable almost as if it throttles the cpu down all the way to the point where its lagging like crazy…Its so annoying but anyways i think im going to try to get a replacement but i do not have a receipt..
They said if you ordered online, you must return online and yes with receipt. They said they need a store receipt (not an online one) to return at the store.
Mine gets so hot doing just dumb things, it can't be working correctly. It will go from 80 to over 100 in a matter of minutes.
Just called customer service and they got me to online store services and I told them mine was getting hot just from simple web browsing and if I could get an exchange. They said since its still within 20 days they can apply a buyers remorse thing and they next day aired it for me. They basically said because I'm still within the return window they'll send me a new one cause they want to be sure I get a good device.
Nice. Good for you. I hope once my new one gets here, I will no longer have any issues. I'm going to run the same apps simultaneously and see if the temps stay the same.
Found out how to fix it ! Factory reset your phone and it will also receive the stability software update. Mins seems better and is charging faster !

Shortened battery life, random reboots, intermittent WiFi ... sound familiar?

I have the SM-T320 (Galaxy Tab Pro 8.4). About 5-6 months ago, I noticed that its battery life began to get much worse (used to last easily through the day, now only lasts a few hours of fairly light use). About two months ago it started suffering from random reboots at odd moments. I had been using one of the CM ROMs and tried others to see if I could solve the problem, with no success. Over the last few weeks the reboots have become so frequent that the tablet is unusable (random reboots every 10-15 minutes) and WiFi has also become unreliable -- the tablet seems to be able to "see" my home network, but can only occasionally get an IP address (even though the signal is strong and other devices have no problem).
Based on the fact that these symptoms have persisted through different ROMs, I strongly suspect it is a hardware issue.
I am wondering if anyone else has experienced these types of symptoms, and if so, how you solved the problem. I don't want to start opening up the tablet unless there is a good chance of success. Is this something a battery re-seat would fix?
Well the second Tab Pro I bought, after trashing the one I received for Christmas. Had a broken Anntena. No clue how that could have happened. As it's a very tiny Board that sits in the lower left Corner that has a Socket on one Side and the missing Gold Finger on the other. The upshot of that was I could only pretty much see the local Net. And Bluetooth had like Zero Range. Replacing that Part with the one from my first Tab Pro I managed to fix that.
As to the Battery, again the consensus here is that it's likely a somewhat lose Battery connection. So I would investigate those Threads for more Details.
Thank you. I did open up the case and re-seat the battery -- and the result was a boot loop, so now I'm not even able to assess the Wifi issues. I will have to spend some more time on it.
Might be a failed battery.

^ That thought crossed my mind as well. The behaviour I'm experiencing at the moment is as follows:
When I plug in the USB charger, I get a boot loop ("battery charging" icon followed by a few lines of text on the screen, followed by a "battery charging" icon, followed by a few lines of text on the screen, etc.) This happens even if I haven't tried to turn the tablet on.
By holding down the power key and the volume-down button I'm able to get to the "install custom ROM" screen but can't continue past it -- pressing any other button only gets me back into the reboot loop.
I found a few tips online that I'll try out later -- otherwise I'll have to decide whether it's worth it to buy a replacement battery (anyone have a good source?)
-The shortened battery life must be due to being used excessively maybe.....It is recommended that you factory reset the device every 6 months so that it doesn't get wasted like that.
-And the reboots is probably because the Memory being used too much as well, once a limit has been reached it reboots so that it doesn't blow up!
-The wifi issue is very common, the SMT320 has a problem connecting to poor connection wifi...make sure your speed is fast enough and is quite close enough to the router. If that doesn't help, try restarting your router, mostly works.
The boot loop is a very annoying thing, make sure you are not dirty flashing and do a clean one,i,e, wipe your system,data and cache and flash a simple and smooth rom....your choice.
Hope this helped in some way....

I have a bit of an update on this, for anyone following along or who finds this thread in the future. Re-seating the battery -- for a third time -- ended up solving the boot loop. The key was that I needed to leave the battery disconnected for an extended period of time (overnight). Things are mostly back to normal now, though the battery life is not what it used to be, so I may buy a replacement.
Tried rolling back to stock?
Had a lot of random reboots with cm, so I tried rolling back to a deodexed, deknoxed, debloated stock ROM.. problem dissapered... Then came back now after I've had the tab for 18 months. But only happens when battery is below 50% and screen light is fixed (turning on auto dimmed the screen a bit but stopped the reboots).
I have a T325.
Cheers!
