I recently hard bricked my LG G4 and I was given this phone by someone I know. The phone had a cracked lcd which has since been fixed.
I reformatted to phone back to stock firmware, DOK2. And. I followed the instructions in how to root and install twrp to then ultimately install a custom ROM. Got all that and I have a custom ROM and I am rooted. But the phone lags like crazy. I am trying to type now and I am tapping faster than the keyboard actually acknowledges. Also, if I try to watch Netflix or even an embedded video from the browser, the video "hiccups" every 8 seconds or so.
What I have done.
I wiped the entire phone, including internal SD and external. I did this twice and I Odin stock twice. After I tried the custom rom and experienced the lag. I started from square one again. BTW, the lag happens on stock ROM, too. I have tried Ovrdrv and tek hybrid on both I have SU 2.52 installed and I tried beast and emotion kernels. The lag is real. Maybe this phone is designed to work in this manner when compared to my G4,rip.
On a side note, this phone was given to me in not the best shape. I mentioned I changed the LCD, but the phone's back button and fingerprint scanner don't work. It is also missing the stylus, but that's not a big deal for me. The charging port works fine and so does the recent button and both the back and recent light up. At this point I am thinking it's a hardware issue and it's conflicting with the software somehow. I downloaded different keyboards but they all do the same. I can type maybe 5 short words before it freezes for about a second.
Videos playing directly from device also lag like streaming services, but mp3 and music do not lag.
I can't help with the Note, but did you brick the G4, or did it die because of the known hardware issue? Those phones are dropping like flies. I had one that recently fell into a boot loop out of nowhere. AT&T replaced it, no questions asked. LG has acknowledged a hardware issue. Bad connections on the mobo, I think. I sold the new one to buy the Note. Didn't really like the G4 anyway!
How long did you allow to settle before you wrote this post? The phone needs a couple days to settle before it runs optimally. Did you install any apps or mods such as xposed?

I am hoping someone has dealt with either of the following problems, and come up with a way to effectively diagnose and fix either.
The phone - 1101 build; running AT&T Stock KK4; rooted via kernel swap method (using stock KK4 kernel after swap, i.e., do not have clockwork recovery); some AT&T bloatware frozen with TiBu, otherwise stock with root
Problem #1 - roughly once a day, the phone will freeze when in sleep mode; I have had this happen with both the slide to unlock and Exchange PIN lock screen up; when I hit power to wake the phone, the screen wakes up but is unresponsive and then the screen won't shot off again; live wallpaper is frozen in place, but if the phone was plugged in, the battery icon continues with the animation loop. And if the phone is not plugged in, battery power drops rapidly in this state.
The phone isn't completely dead, because if I connect/disconnect it via USB (set to debug mode) to my laptop, the computer recognizes the phone is connected, but it is dead enough that if I call the phone, it does not recognize the missed call. The only way I can restore the phone is a battery pull. Usually it takes several minutes for the phone to come back after this, acting like it would if I had flushed the dalvik cache or installed an update.zip from recovery.
Problem #2 -also roughly once a day, at random times the screen will wake up momentarily, then clear, and I will hear the AT&T boot up sound, after a short while, the phone will run through the media scanner and any other startup launches, acting as though it had been turned on, but the battery stats show continuous uptime throughout. I have had this happen when using the phone, including when on a phone call (and the call did not drop).
I have seen problem #2 on virtually all of the AT&T GB leaks, and it seems to get more frequent the more apps that are installed. I had not seen problem #1 until recently.
The phone is out of warranty, and owned by my employer. I am not due for a new phone from them until July. I've done more master clear/reflash stock cycles than I care to admit, tried replacing/testing for disk errors the external SD card, etc..., and am afraid of doing that and having the problems come up again.
Any thoughts on how to diagnose either of these problems?
Hmm... I don't really think there is an exact diagnosis for any of these issues. Some phones are just problematic like that. The only thing I can suggest is trying a different ROM or kernel, and that might help your stability.
I have the exact same problems. Hope someone comes up with a fix. The only help I can give you is that when the phone freezes, instead of pulling the battery, you can hold the vol up & power buttons for 10 seconds and the phone will restart. Easier than pulling your phone apart, especially if you have it in a case, like I do.

So, the way I see it, unfortunately these problems could be a function of:
Bad hardware
Misbehaving app
ROM issue
Kernel issue
I tried pretty much every leaked AT&T GB ROM and had random reboots with all of them. Seems to track with the number of apps installed, but can't prove that. I have not tried any custom ROMs or kernels.
Since this is technically not my phone, I am trying to avoid doing anything that can't really be undone if I need to turn the phone back in at some point. And I need something that can be a daily driver for work calls and Exchange email, and rely heavily on tethering when I am on the road.
Anyone with ideas on what to test, or how to capture enough log information to figure out where the problem is, would be a big help. Otherwise, I am stuck riding this out until July when I can get a new phone from my employer.
Nothing you do can't be undone, it's just a simple Odin flash away.
Be sure to back up your efs folder before flashing too much

I've used Odin with the various GB leaks; if I go further afield (heck, performance is dicey already, how many more problems could I have with one of the ICS alphas), is it still a straight shot back to stock KK4, or are there other steps to do first?
And before I go down that road, any suggestions on diagnostics (other than yet again pulling apps off of the Captivate to see if one of them is the culprit...?)

You actually might have less problems on ICS. But it all depends. You can always get back to stock with one, bootloader-free, safe flash. Diagnostics wise, there isn't really much you can do besides removing apps. I would only worry about the ones that are constantly running in the background, as they could possibly be screwing with the phone while in sleep. I think it's unlikely that this sort of testing would actually help though. I still say try something different.

I am having the same issues except in my case I have tried to recreate the conditions and check memory and I am close to maxing it out. Part of my problem is that I come from a Palm background and I have found that Android, or at least the Cappy, is not as responsive (I was really spoiled by Cards on my Pre) I was thinking that my Android noobness is causing me to push the phone too hard and locking it up. FWIW, you might want to check memory issues
Its a Hong Kong bought LG P990 with GB, bought two years old. Rooted but 100% stock, just deleted pre-installed apps. At first it happened only once in a while, now maybe 1-3 times a day. It won't turn on. I don't know if its actually off or if the power button doesn't work. So I have to pull the battery and restart.
Its seems that about a year ago one day the power button require quite a bit of pressing to get it to turn on. Like I have to push really hard just to get it to turn on. Its been that way ever since. I always would have to do a restart every week or so because the thing would get REALLY buggy or REALLY slow. Then it started to not turn at all, the power button. It would do that about once a month, then once a week, then three times a day yesterday. This happen exponentially.
Its always been buggy and slow. I only have about 10 apps on it. Barely using any space.
Is it dying? How to tell if your smartphone is dying? How often do people replace their smartphones?
hi! you should try to:
a) flash the rom again and try to do it as clean as you can(try a hard reset then flash)
b)either use a rom that is already modded without the apps that you care to get rid off or watch if the problem is caused by the removal of unwanted app
c)have a little patience and test
hope it helps!

Thank you for your help. But I did the root and deletion of stock apps a long time ago. Why is this problem starting to get worst now? Or are you referring to the general slowness?
I never flashed a rom before so I don't really want to start. Unless its the clear answer to solve my problems. Is that what your suggesting? I have thought abut it, but I wonder how much worst I can make it. Plus, I am just scared I'll screw it up.
My v20s stock rooted rom was performing pretty well by my standards but after changing basebands and removing some unwanted apps i had some trouble with playstore(after using 3g internet, when switching to wi-fi it would not download or update apps) and the phone sometimes just shut off removing the battery being the only way to solve both problems.
Since i flashed the new v30a everything is peachy except the phone and that damn chrome app are a bit laggy sometimes(mostly chrome).
My advice to you is to ,one by one, try to eliminate each possible cause.Also flashing a new stock rom is not hard(and i guess neither a custom one tho i have no experience with that) so have no fear and please do read the tutorials for each rom. Good luck!
So i've been experiencing this issue for months now. I've had the issue since i've gotten the phone but its the past few months that its really gotten bad. So before anyone jumps the gun, i've done quite a bit of research on this and cannot find anything worthwhile, more on that soon.
So as usual, i'll pickup my phone and press the power button or the home button to turn on the screen, but at completely random times the screen will not come on at all. Sometimes the capacitive buttons will light up (maybe 15-20% of the time), but not always.
In my searches I found the following solutions to this problem:
Get a new sim card
Dont use an SD card
Get a new battery
Check the leads on the battery and phone for cleanliness
Factory reset
Remove 1 app at a time and test until it stops happening
Dont freeze any apps
Restore stock firmware
Dont use SetCPU
Turn off animations
Get rid of the lock screen
Remove custom message from lock screen
Clear cache through Recovery
Dont restore data with Titanium Backup when restoring apps
Turn off WiFi and/or Bluetooth and/or GPS
Dont use GreenPower or Greenify
Avoid stock launcher
I have tried all of the above except for removing 1 app at a time (and those that dont apply). I'm deep into that one and only have a few apps left to try. This is something that happens at least once a day, but typically 3-5 times in a day. I used to think i could make it happen by pressing the power button to turn on the screen and immediately hit it again to turn it off. It would sometimes work but that doesnt trigger it anymore.
My phone used to be rooted, but being on AT&T there was no "normal" way to flash a good recovery like CWM or TWRP and install roms, you have to use some other thing which i dont use. So i've always had stock recovery, im fully updated to the newest stock rom that is out, update came OTA which was after i removed root and used odin to flash an older stock rom back. My wife's Note 3 also has the same issue and it has never been rooted, we have gone through all of the above and still it continues to happen.
Also on a side note, my phone was swapped out because of an issue it had 3 months after i purchased the phone. I was able to get a brand new one, not refurbished. The issue had occured once or twice before the swap and an incredibly frustrating amount of times since then.
Reading through most of the other threads, everyone seems to have to remove their battery and re-insert it to get back into their phone. The ones that dont have to do that have found that removing their SD Card, getting a new one, sending the phone in, or one of the other options have worked. However for me, nothing has worked.
Does anyone have any other ideas? Is this common on the Note 3 (I've had it since release)? 70% of the time i can hold the power button for a few seconds to try and bring up the power menu and it works, but not always.. I usually just have to wait up to a minute or two (never actually counted, i use my phone for that stuff...which.. isnt..working...)
I've had wake lock lag on a few android phones. Even iPhones.
I would highly recommend rooting it on att and flash a mod that reduces it on the note 3. I talked about it here.

Rebooting the phone always helps.

Unfortunately I cannot root my phone. I have to have my company email on my phone, and for Android devices they use Air Watch. I tried for weeks to get it working while rooted, and even used Root Cloak or something like that (with Wanam Xposed) to hide root from specific apps. Air Watch was specifically tested to work with that app but it still for some reason didn't work (new version of Air Watch perhaps with no update to Root Cloak? Just my guess). I had to remove root, factory reset and re-flash stock from Odin (that was a dual purpose flash) to remove all traces of Root so I could use Air Watch for my company email/calendar/contacts/etc again, even after unrooting and using all the cleanup tools, triangle away, and everything, it still detected my phone as rooted...
However, I don't think that's really a viable solution to the problem, that's more of a band aid. Looking at that thread and looking around, it seems to work well but I still haven't found anyone with my same issue where they used it and it worked. I would like to narrow this down to what the issue is exactly, the root cause. I think its a problem with KitKat, or at least all of 4.4.x (not sure about 4.4.4 yet).
Hi Guys,
I have this phone for many years, but suddenly the random reboots started approx 2-3 months ago, running originally KitKat 4.4.4 at this time. Before that I was rooted the phone and I supposed it could be something with that. However, flashing back & factory resets didn't help at all, clearing dalvik caches as well. What I tried up to now:
1. Upgraded/Downgraded the bootloader -- no change
2. Tried different recovery modes -- CWM & TWRP(the current one)
3. Different ROMs -- no change, the sudden restarts persist.
(4. Updated the radio -- the signal got quite better)
Three days ago I've upgraded to Lollipop 5.1.1 (the Cyanogenmod 12.1), the same story continued after a while (different applications installed).
There's one thing for sure: flashing the factories always results into a very stable phone at the beginning, installing some more applications leads to the same state -- random and frequent restarts.
I've checked the hardware -- the power button looks ok, it's definitely not the main cause b/c it reboots without touching! The CPU temp & free memory look quite good too.
Now, the current situation is as follows:
- flashed ROM (official one): 2016-03-03 Poland (T-mobile) 4.4.4 I9305XXUFOL2 I9305TPLFOL2 (seems like the most stable till now)
- installed ATK (Advanced Task Killer) -- configured to kill all applications aggressively when the screen goes off.
For me it looks like the ATK helps much, although I don't know the reason. Also, memory checked, I've executed all kind of possible tests up to the phone -- all appears as OK. Also, I don't know if it's related to the issue but I moved all possible apps installed to the SD card. The internal memory has been formatted via TWRP before the last ROM installation... Does anyone have any idea what could be the reason for the sudden restarts? It restarts even in Safe Mode, without any obvious reason and not touching the phone at all. The CPU load at the times of restart is quite low, the temperature as well. I doubt if the RAM is corrupted or maybe the NAND has some bad blocks. Are there any useful utils for tests that could be executed?
PS: I attach some log file, which I gathered once I was running the Cyanogenmod 12.1 (Lollipop). As I stated above the situation is the same when running 4.4.4 and 5.1.1. Sometimes after such a restart, it sticks in a boot-loop (if I boot manually via the GUI in recovery or download mode it will not).
Current versions:
---------------------
Android: 4.4.4
Baseband: I9305XXUFOA1
Kernel: 3.0.31-4282983/[email protected] #1
Build: KTU84P.I9305XXUFOL2
SELinux: Enforcing
Recovery: TWRP
I beg for your help on this! Cheers!
Same problem here...
Hi there
I'm having this same annoying issue with my Samsung GT-I9305. It suddenly restarts without doing absolutely nothing but looking at the screen or scrolling a text or just sending a sms/whatsapp/whatever.... I started trying to restart the phone (nah) turning it off and back on (nah) changing the battery for another one that I have here with me (nah)... After that, I extracted the SD Card and leave the phone only with internal storage (again, nothing happened but restarting randomly). I tried not installing apps such as FB, even Pebble App or just stopped sycronizing my phone with my Pebble Time via Bluetooth, but with the same and well known result: still restarting suddenly. I have noticed that when Google Play detects that there are few apps with a newer version asking to be updated, the phone restarts too! I tried deactivating this option in Google Play, just letting me to decide when and how to upgrade my apps, but It seems that it still detects the app upgrading needs and keep doing it the same way.
About a year ago, I found the same problem with my phone, but in that time it was related to the power button, it seems that it was pressed all the time and the device felt into a rebooting cycle. I check some blogs and I solved the problem cleaning the button with this electronic cleaning spray. I almost drowned my Samsung but I let it dry for a few hours. It worked fine, until now.
My cellphone is still in Android 4.3 (I9305ZHUCNB1) I don't know why I can't upgrade it to a newer version, even when I see that the 4.4 is available for this model. Right now, I'm thinking about change the cellphone and just forget the whole problem. But I'm just exploring again to see if I can find a last solution that tackles this annoying issue.
Did you manage to solve this problem??
Thanks in advance!
Unfortunately not, I had to buy a new phone. I guess the processor or other element suddenly broke, there's no other explanation to me. Also, as you see no any reasonable support in the forum.. Anyway, wish you a good luck with this.
Not so good here too...
Thank you. But unfortunately for me too... Today my phone went black screened suddenly, when booting only got to Samsung GTI9305 logo... I tried to restart through secure mode and the other one you get pressing power plus home plus volume high, and when tried to do a cache cleaning and rebooting it showed some mmcblk failed issues. So I couldn't do so much to revert this situation. I already bought a new phone, not Samsung of course. I have read that some people had the same problem as me just because they let the battery reach a very low level in one opportunity, and something in the internal memory went broke. So it was a great phone, for three years and half, but it's so bad that it fails this way unexpectedly and without any apparent reason...
Yeh... There's no much support here, especially with old flagship cellphones...

Sorry for bothering this thread also... I got success by replacing the display!
Hi all,
I am completely running out of things to try and do now.
After installing Android 7 on my Note 5 I had the strangest issue that i in general have never seen on a phone. The screen is simply black (which isnt that strange) and the phone is fully functional. Bare with me, after reseting it multiple times so it would finally come on the screen goes crazy and turns goes into so many colours (if it turns on that is). Its either that or jumps all around the phone, quite literally it glitches out completely. Its like one of those virus cut scenes you see in movies, it goes different colours, glitches out, jumps around and completely misformats.
From the beginning i knew this was not a broken screen.
So far i have tried.
1. Factory reseting the phone. That gave me about 5 minutes of normal use until i locked the phone and it wouldnt unlock again.
2. Factrory reseting multiple times... again to no avail, it would work for short periods of time and glitch out again.
3. Reflashing stock Android 7 in Odin. - No avail.
4. Flashing Dr.Kretans Rom... worked for 1 day which made me so happy and think that the problem was solved but then the same problem persisted.
5. Installing Arters Kernel.. (arter97-kernel-n920cig-22.0) Nothing... literally did that today and still NOTHING
6. Re partitioning. Quickest process and no avail.
In more detail, if the phone does sucessfully boot, and bare in mind sometimes it takes more than 2 hours to get ANYTHING on the screen (including recovery which doesnt boot up either until the initial apperance of something on the screen)
I tried taking the phone to a phone shop before doing anything myself and since in England this phone was never released theyre refusing to touch it. I tried calling samsung and they dont want to do anything either cause its not a UK variant.
Could someone please tell me anything else i can try. I feel like im totally running out of options here.
My phone details are as follow
Galaxy Note 5
SM-920I Singapore Singtel Variant
Running on 6.01 (i downgraded from Kretan)
And the kernel is the one previously mentioned v.22.0
I would appreciate anyone's help or suggestions so much at this point. All these problems started since the 7.0 update a few weeks back :/
Oh its also running TWRP recovery (arter97-recovery-n920cig-22.0-twrp_3.0.2-0.tar)
