[Q] G3 still worth it with overheating and other bugs?

Hello guys,
I'm thinking of buying the LG g3 which for me is the best phone right now. However, I have seen it has some bugs regarding overheating, WiFi drop, bad battery life etc.. Do you think it is still worth it or should I go for a Z2 which has the same price in my country (Spain). Regarding the overheating issue, a lot of people say they have it and a lot of people say they don't... Is This just chance or is it linked to a specific model and version?
Thanks

Watch that and make your own mind up - this is the opinion of Pocketnow - 3 months after launch.

As the overheating, since I upgraded to v10L firmware, overheating issues it completely gone for me, even after 40 minutes of playing Real Racing 3 on max detail mod or Dead Trigger 2 for about half an hour. It still heats just like every other device ( HTC, Samsung or Sony) but it doesn't get to extreme temperatures which turn off your phone automatically. What are those other bugs you are refering to?

I have my LG G3 for 2 months now and I never experienced any random reboot,except for 2 times when it said the reason was extreme temperature, but that got away after updating firmware and never happened again. But it was only when I had first firmware. I also use ART as runtime which is considered to be buggier and more "app crashy" than Dalvik, but I never got any crash or random reboot.. Usage of unoptimized apps can random reboot any phone. As for LG software, LG's apps and the most common and most widely used apps work perfectly without any hiccup. You should never experience any error, crash or random reboot. At least I didn't. Always try to use trusted and well optimized apps if you want the best experience. Also don't install any battery or RAM cleaning apps, that **** just slows down your phone and drain your battery rapidly. It depends on you if your phone will random reboot or not. It's not just LG thing, it also concerns HTC, Sony, Samsung or any other manufacturer. You can ask my sister, she installed few cleaners, RAM boosters, 1 optimizer and 2 battery boosters on new Nexus 7 which should be most stable Android experience, but her battery life got worse and she does often get random reboot. So treat your phone well and it won't random reboot anytime

GN4 Wifi Dropouts, Camera Lag

I believe im having some software/driver errors (using NJ5 Retail) I don't think these are hardware errors as we both got our phones as different places and different times and it would be strange to have the same issues. I believe its a Note 4 problem.
1. Both my wifes and my Note 4 phone's seem to be having WiFi dropouts (not at the same time) ... its not a issue with any of our other WiFi devices and my daughters S5. I did wonder if it was our router (Netgear R6300v2) but its rock solid. So I tested it at local wifi and ran some heavy data and surely enough intermittently it "locks" up. So far haven't seen any issues with 4G LTE, but then again we tend to avoid heavy data usage on that.
2. Also on both of our phones Intermittently the camera will lag really bad as well, its as if im running a million apps and have no memory. Yet I have over almost 900MB of free ram and 20gigs of free space. I also have confirmed I have no apps running and so far the only fix is to reboot the phone which is a rather inconvenience when im looking to get a picture at the time it happens.
I haven't yet tried another camera app to see if the same thing happens. Which I do enjoy Google's camera app and had that on my old Note II, however again I am wondering as to why this is taking place.
A few other things noted the phone this has happened while the phone is unplugged, heat doesn't seem to be a issue atleast for the battery which sits around 30c for wife's and 26c for my mine most of the time (according to cpuz)
So is this something to wait on Lollipop for to maybe be fixed or is this possibly a real hardware issue.

We used to get dropouts too, I recently switched my router to Wireless N only and now all phones and devices get a steady 90 Mbps up and down in our house on a Verizon FIOS 75/75 plan. I've always had dropouts on phones and am surprised that Wireless N made such a difference. Still using the same 2.4ghz frequency that we did on the G network, just zero interference to cause dropouts now.

Update after more issues .. I took it back to the store and we fiddled (the store had a tech who was geeky and it was great) and sure enough we discovered how to duplicate the problem. Also after testing a few other phones it seemed to only happen with ours .. so we wondered if it had to do with our failure of Sandisk cards but who knows (which we are doing a RMA on them).
What happens is under CPU-Z (play store) we noticed even under heavy use only 1-2 cores were being used. It would never use all 4. So we tried gaming and running hard games and background things and sure enough stuff would lag real bad which then would lock up the internet and camera. Then we tried Antutu and it locked up, and score was terrible. It was then we decided the phones had bad cores in it. So Wife exchanged her's and I refunded mine and ordered a developer one .. as ive been waiting over a month for and should have stayed waiting. As for what started it all. We had a batch of the Sandisk Ultras that kept failing however I dont see how that could have been the cause. The sandisk error I guess is very common as soon as I mentioned it they knew all about it and their forums are flooded with posts about it.
So if anyone has these issues test your cores.

[Q] Overheating 🔥?

I just got my Samsung Galaxy s6 edge white 32gb last night and I noticed that is over heating than it should be. I'm using it for Web browser and texting nothing that should cause to heat up. I also updated to the latest version.

Actually if it was overheating then the phone would automatically shut down to prevent damage, but yes the phone does get hot rather quickly. But I've had glass and aluminum phones before and they always get hot fast since metal retains heat.

Mine ran a lot hotter than a normal glass and metal phone, and it was laggy/jerky. I flashed the stock firmware to it, and now it's smooth and cool.
Here's How:

yes it does get hot once in every 3-4 days & when I say it means really hot..

Smart switch is not working for everyone. Hit or a miss thing.

My phone heats up to 44 C
What is the Warning Level is it safe till 45 or 50 Celsius ?
It happens when
1) On use of Google Maps while driving
2) Charging
3) When i use Sandisk OTG, to the extent that it stop the Transfer & freezes
4) Even if i Record Videos sometimes
5) While wireless charging
This is really bad Never had such a Issue

I agree with some of the sentiments here that the device can seemingly get pretty warm - especially when I tweaking things or using apps that use a lot of CPU or using the camera for too long. But I do believe a lot of it is related to the aluminum/glass case - I believe Samsung is basically taking advantage of the case as a though it were a heatsink - releasing all the heat into your hand/pocket/air.

This is truly the first phone i've had that manages to stay under 100° F even when cpu frequency is locked to the maximum and I'm playing very gpu-intensive games, provided that i'm not charging the battery and the phone is not in an unusually warm environmnt like a hot car. I should mention that i'm rooted and lots of preloaded software has been removed. I would download some sort of process monitor and check it to see if there's a misbehaving app to blame if this is happening regularly.

Hey,
I saw that you posted a solution when someone had problems with his S6 edge overheating. I've an S6 and I think I might have the same problem.
I was wondering if you could spare some time to help me. I posted my problem here. http://forum.xda-developers.com/galaxy-s6/help/help-s6-cpu-getting-hot-t3180011
I used Antatu benchmark and CPU temperature to test my phone and it got to 84.0 C twice, once when it was testing my CPU to it's fullest and once when it was testing game performance.
So I was wondering if you could run the test as well and tell me what temperature you got so I can compare. Thanks
I haven't tried your method yet but I will tomorrow.

For the record, mine just hit 85C while running AnTuTu. As far as daily use, it made a world of difference on my phone when I flashed the stock firmware the first time. The phone was terribly hot in my pocket when I was not doing anything, and it was SUPER laggy when I was. Not something I expected from this phone. After the flash, it was a Beast and ran MUCH cooler. It would get warm still when doing intensive tasks, but that would be expected from an Octa-core phone in my opinion. It does not get uncomfortably hot anymore, like it used to though. I would imagine it went WAY above 85C when it got hot before, because it was actually hard to hold at times.
If you have not flashed it since new, I would highly recommend it. I know it's a pain, but it's a one time thing that you never have to do again, and the benefit MIGHT be large. No guarantees, as you may not have the same issue, but I've received a lot of reports from people who have done it and they say it breathed new life into their phones. For me personally, it was DEFINITELY not a placebo affect. It was night and day.
With all that said, I've got my S6 Edge up for sale right now as I've moved to Apple for a little while. I continually jump around, and T-Mobile offered the iPhone 6 for $15/mo and I can trade it in 3 times in the next 18 months for free and keep paying $15/mo for the newest phone. I'm looking forward to seeing the difference in the iPhone 6s. If it sucks, I'll be trading it in shortly for another Android phone.
PS: AnTuTu final score: 69314!!!! Wow!!!
One more thing. To eliminate ALL lag and slowdown, I replaced the Samsung Launcher with the Google Launcher. What a difference that alone makes! Seriously, try that one thing. It's huge. The Samsung Launcher has some issue somewhere that they still need to address.

It should. As long as Smart Switch can recognize your phone model and download the Correct Firmware, the Flash WILL help the Heating and Lagging problem. If your phone is not recognized, then Smart Switch will not do anything. It's worth a try.

For me it happens especially when im playing arround with that samsung theme store build in app. I don't know why that app needs so much power to have that effect on the phone but for sure its something samsung needs to look at.
For sure they need to re-design that app from the scratch. Its like the "my first homepage" of theme apps.

How are your device doing ?

Hello my friends, I've been a user of this tablet since 2014 and i came to the point that im done with it. So i made this thread because im curious how are you guys out there holding up with yer Notes 10.1 too. Here are my current issues :
Every time i flash something its a time to pray a lot, lots of force closes. Even if i flash a factory image in odin and then flash a rom the odds are of a lot of trouble coming, you wont believe how many times FireFox died today on the same page.
TWRP is a no go for me. I usually can successfully restore a backup on a 1/5 ratio and since a wrongly restored backup ends sealing the death of the current installed rom its easier to just wipe everything and start from the scratch again.
I was in such a shock after rooting my Motorola Droid Turbo, because it didn't blow up or something. The Samsung knoxx software is just troublesome. I didn't wanted to switch to CM13 because of dead camera and some other bugs. But hey that's what has been happening to me, how are yours tab holding up guys? Mine is p601 by the way, maybe the other models are doing better.:silly:

Hmm, probably you just have a defective device?
I have a second hand P600, the WiFi model, been using it for over a year without much hindrance, and I average over 8 hours of screen time over 4 to 5 days of usage. 9 to 10 hours if used for continuous web browsing. The only problem is the WiFi antenna/driver might be buggered somewhere, because like once every couple of months it would completely forget a previously used WiFi point, like literally cannot even see the SSID listed on the WiFi screen, and the only solution is to either change the frequency of the point from 2.4 Ghz to 5 Ghz, and if that didn't work, to completely flash a new ROM. Luckily that only happened once, and just before I flashed a new ROM for unrelated reasons.
Regarding the modding part, I've flashed lots of ROMs and kernels, and the only significant problem is from running xluco's kernel, absolutely nothing wrong with that one other than the frequent restart due to some S Pen problem. The device would randomly restart itself at any moment the S Pen is used, and the fix that was provided by him in his thread didn't do much to change this. I suspect each S Pen model is different though, I used the larger type that Samsung provided for the older Note 10 model, it runs smooth under completely stock Lollipop ROM, but crashes the device frequently if I use either Xluco's kernel, or the 4.4.2 Hyperdrive ROM.
TWRP works ok for me, and I have never suffered any app closing issue. Anything more you'd like to ask?

I'm running ZakooZ CM13, customized Valex Kernel flashed via TWRP. This baby flys! No problems with Spen either. Stable and Fast! Oh, the camera works as well!

Ye i have the same feeling, i was very confused since we don't see many roms wandering around the 2014 forum, its pretty different from my experience with the Galaxy SII for example. I think it all started back when i tried to change the partition to F2FS, had some troubles with SD card too (multiples mount/dismount) all the info i managed to find was to buy a Samsung SD card instead of using another brand. Most of the CM roms worked ok before flashing GAPPS. Anyway i formatted the SD again and tried to flash pcparaamigos rom and for my surprise it did work (I've always been struck on the "extracting system" on some roms), maybe it was an issue related to the SD card slot since im now using the internal partition to flash roms and do backups, gonna need to run more tests, or i got lucky i dunno, sometimes i get the feeling that my device is a living being or something.
I found also hard to find a new replacement for this tablet, one which has better specs overall, not many 10.1+ screen tablets around and gsmarena doesn't tell if they have Pen support or something, just specs.In the end it feels like this tablet have a lot of potential but $am$ung just forgot about its existence.

Not well. I think the device is on it's last legs.
Battery life is beyond terrible, and I even replaced it with a new OEM battery. It was fine for about a week, but it is doing the 30% to 0% within 5 minutes trick again. I wonder if a sensor is out of calibration or is failing? Also, the thing lags beyond belief. Even after a fresh factory reset with no apps installed, it can barely render a webpage without bogging down.
I will end up replacing it; just not sure with what yet. Perhaps a Chromebook that flips between laptop and tablet or another plain 9.7" tablet.

I had the same issue on the Galaxy SII, a reboot was like 10% of battery per reboot I have my eyes on the Lenovo yoga book or the Yoga Tab 3 Plus, dunno about the projector version, the microcrap surface looks like an interesting device but windows 10 is such a let down. I don't wanna buy another Samsung device because knoxx and update issues.

Have you tried battery calibration software? There's this new tweak app released on the Play Store, it's called HEBF Optimizer, has a pretty romantic design and philosophy for that one. Anyways you need to be rooted first, and there's an option within there to calibrate the battery, but make sure you do it while being charged and the battery is at 100% first. Also, perhaps try flashing a new ROM, maybe an AOSP one? I've flashed lots of stuff on my tablet and I've yet to experience any noticeable, prolonged lagging.

That looks pretty neat, a little xpensiv too :crying: The Thinkpad looks okay too maybe if we cant put a win7 there it can shine. I live near Paraguay and we usually find all kinds of electronics in there! Its a buyers paradise, its my last resort if i can't find the model in my region.

Not that I'm aware of.
Edit: heres a quote from another site
"S Note, Action Memo, Screen write(Air command) etc do not work(read about touchwiz if you want to know more on this).
Replacement Apps exist in the Google play store that use some of SPen's functionality -
"CM S Pen Add-on (Root)" with "Note Buddy(Spent helper)" give you a functuonality similar to the stock Samsung's "air command"(that popup that show when you detach your pen)."
I use both of these apps and they function great for what I need.

Thank yo for your help. I'm in a middle of a lot of reading and compiling texts, so this might be my door to the 6.0.1 world

Mine still works pretty fine ... except the touchscreen ... sometimes very randomly it doesn't react to touch any longer only the spen works in those situations.
A quick on off fixes it.
I'm going to replace the battery soon and while i have it open i am going to check the cable.

Mine's still doin ok. On a 1 - 10 scale I'd say mines operating at a 7. The only issue I've ever had is with the battery. After the original battery failed competely I replaced it with an aftermarket one. It was a great improvement over the original battery, but it also brought its own set of issues. Many of the aftermarket batteries for these don't handle heavy loads well, leading to a sudden shutdown. I've reduced my CPU output to remedy this so now it rarely shutsdown under heavier loads. Other than that, I still love mine. No twrp issues, no problems when I flash anything (which I do regularly). Currently running OrionOS Marshmallow, which is a great ROM. All in all, still a great tablet that I have subjected to heavy daily use since it was new and continue to use heavily every single day.

Mine is still fine. I think a lot of the problems come from not using a case with a rigid back. Pressure on the Note's back could lead to the loosening of the connection of the cables running across the battery(display, backlight, touchscreen, usb).
And the plugs of most aftermarket batteries seemingly don't fit properly. So you'd have to reuse the original battery's plug by soldering it to the wires of the new battery. Probably the pins of the plugs can be unpinned with a needle (that works with DIL plugs) and the pins of the new battery fit into the old plug.
Then there's the thing with the bubbles under the screen. This seems to be caused by strong pressure on the capacitive buttons or comes from the closed lid of certain cases, i don't have that problem myself(my Note is from Nov '13).

Question Phone Overheating - Is There a Fix?

I'm on Android 13 and was hoping this would sort out the overheating problem I had with Android 12 (I read in a few places that it would), but it did not. The phone gets very warm when charging, and hot when streaming video, and just generally through simple use, nothing particularly demanding. I haven't rooted this phone because I did not see the need, but I would consider it if it was the only way to fix the problem. Is anyone experiencing the same, and does anyone have a solution?

I could be wrong but generally speaking in my experience, going from one major upgrade to another the phone works a bit harder to re-train itself to your use patterns. I just did my upgrade yesterday and experienced some slight to moderate heat as well. I also noticed that battery is draining a bit faster which I think again is part of the process. I'm going to give it a week or so and if I'm right it should improve.

I'm biased because I've had my Pixel 6 Pro rooted (and updated every month) since last November, and I also use Kirisakura custom kernel with its companion apps and currently have the one app set to the maximum battery savings.
So I can't really compare to 100% stock unrooted with the stock kernel, as I'm only briefly on the stock unrooted kernel each month after I manually flash the latest update.
Several others have commented, and I've experienced too, that with Android 13, we've no longer experienced as severe higher temperatures when charging. I don't remember if the others were rooted and using the same custom kernel, or if these were general Android 13 comments, so your mileage may vary. Sorry I can't give you any more concrete information.
Good luck!

Granted this is for my 4a5g but I wouln't be suprised if/when I get a 6 that its battery performance would be less than stellar after a good days use of phone and/or screen and radio/network. i.e. stock. Before I went to Lineage on my 4a5g I think my battery would cut a good 30-50+ percent each day. I put lineage on it and I poop you not, can go from a 75% to around 20% in about 5-6+ days. I tend to have my screen brightness around a little less than 1/4th on the slider bar.
When I had an HTC M8, after around 2 or so years (this was around 2016/7 or so. got phone oct '14) on the stock firmware the phone couln't keep it on for more than a day. Ran ViperRom for a bit then switched to cm/lineage and that stretched my usability of the phone another 5 years. It got to the point where the phone would shut off when it got to around %50 charge and go ding dong and turn off--without pluggin it in I had about 8 hours run time on it. My battery was beyond gone and no way would I have gotten that usability on the stock rom.
So, to answer your question, yes, trying different roms and kernels (rooting) could be to your advantage to prolong the life and performance of your phone.
Even if you choose to run the stock OS, with root, you could disble any bloat running in background. Kill any programs/services leeching CPU (and hence battery) cycles. You could definately make it run more efficient for YOU. Maybe not for the next guy who needs his facebook, twitter, ticktok apis and stuff loaded and at the ready. Everyone is different. But they tend to make the phones (they think) for everyone. in mind and as a result, device performance and lifespan become affected.

I definitely have heating issues and this is on a warranty exchange. The 2 previous P6Ps had all the same issues as this current device.

My phone was hot on A12 (41/45°) and since i clean flashed A13 and wiped it is cold (32/35°) for the same usage.

Greetings.
Good topic.
I have bought this phone a day before. I'm facing device heating even under simple tasks like scrolling messengers, browsing etc.
Previously I had OnePlus 7 Pro (Snapdragon 855), that one was cold all time except while charging or playing games.
However, Pixel looks warm or even hot even upon light using.
I'm a bit confused about that.
Is it a common problem of this device? Or probably exactly my device is affected?
I haven't faced overheating or alerts about that, however, it feels hot for my hands that got used to feel a cold phone while low load.
Currently, I have about 37-38 degrees while browsing on XDA and writing this post.
Just wondering that digits you have?

I did a warranty exchange on my P6P for a different issue and I'm glad I did. My replacement device has much better thermals than my original. My original one would get quite hot while charging and restoring apps and was almost uncomfortable to hold and to the touch. Could always try a warranty exchange and see if the replacement device is better for you. Also, Kiri kernel has been reported to help with the thermals. I've seen several reports of users commenting that their device runs cooler. Good luck!

I had heating issues and battery issues when I first received my P6P. Once I got it out of the box, I set it up and restored backups, rooted it, updated to android 13 without wiping, rooted again, and then flashed the Kirisakura kernel. I decided to try and flash android 13 again but keeping the -w flag to wipe userdata and didnt restore my backups and I've had amazing battery life and no overheating. If you haven't yet, try doing a factory reset. As simple as it sounds it may very well help

My fully stock P6P (on A12) gave an overheat warning yesterday while we were having a day out, it was only 22°C although we were in and out of the sun as the clouds rolled by but the phone was showing 46°C after being sat in my pocket.
I think Google have released the worlds hottest running phone, i have never owned a phone that heats up so much and so fast.

Thing is I have never experienced overheating on any phone (that i have owned) in UK before, using an Exynos as the basis of Tensor and then whacking an extra big core in it was a pretty bad idea unless you live in a fridge.
