[Q] L3 (E400) reboots after hitting Wi-Fi icon - Optimus L3, L5, L7 Q&A, Help & Troubleshooting

I know that this question has been asked before but I'm getting desperate . I had problems with Wi-Fi even with the stock ROM. However, back then phone didn't reboot but it lagged for some time and things went back to normal. Now I'm using the Latte ROM and sometimes if I activate Wi-Fi my phone reboots. Why is this happening that L3 is struggling with Wi-Fi?
I found a temporary fix by using Memory/RAM apps before I hit Wi-Fi button. It works every time (without reboot) but it's annoying because by freeing RAM you force close almost all apps and then phone lags after you (for example) play a game afterwards. Is there a permanent fix for my suffering? Are there other L3 users with same problem? There must be some sort of a fix like flashing something to fix it.

No reply. Seriously?!
Well, it seems to me that the only real fix is to stop using Wi-Fi or buy a new smartphone. One thing's for sure. No more LG smartphones for me!
P.S. I still can't believe no one cares about this issue. Oh well, considering how bad this phone is probably all of you switched to a better phone by now. I can't blame you for that.

Xperia crash

i have my xperia a couple of weeks now. i like it very much but for one thing it crashes to much. the rom is orginal i didnt change that. i even used hard reset but didn't solve the problem.
it happens mostly when i click the x panel.
does anyone have the same xperiance ( ). or does anybody knows why it crashes plz tel me.
Xperiance >.> ... it happens to me,, a lot, i got my phone two days back..
Unless you have touchflo 3d on your phone which cases it to crash like that. Nothing should crashes your phone like that. Hard reset and see if it does that again, exchange your phone if it does cuz thats not normal.
no there is no tf3d
i did a hard reset yesterday.
sometimes it works great doesnt crash i can use everything. but somethimes i want to change panel i press te "x panel" it doesnt do anything i'm forced to use the reset.
i want to know of its hardware or software that couse the crash.
Mine does this randomly as well. I’ve seen it in a hand full of forums and it seems to be normal. The only thing I’ve installed is the Garmin XT software and it’s never running. I’m just guessing but I think most all of them do it but it’s being attributed to popular hacks and add-ons because it’s random and untimely and/or they exasperate the problem. It’s even one of the rumored reasons for the rumored recall. There are also some odd charging issues.
I’m trying to decide whether to keep it, hoping for a firmware fix or return before the 30 days runs out.
ok thats means im not the only one with this problem, hope sony does something a fix or something.
what do you mean with odd charging issue? like when charging it gets very hot?
i have that sometimes to only when im using the phone and charging.
i think there wouldnt be a recall for crashing i think it has to do something with the panel and maybe a hotfix can solve the problem. im curious of someone using a custom rom of they still have the crash problem. if anyone can reply that has a custom rom??
Sometimes it gets really warm and though it says that it is charging, it's not.

How to solve phone unresponsiveness after using GPS??

Hello everyone, i've my SG3 flashed with Gsam101 ultraclean SPF rom + modified JPB kernel + lagfix v2!
I've solved the GPS slowness using the post http://forum.xda-developers.com/showpost.php?p=10385614&postcount=43
The main issue is that opening googlemaps already slows down the phone (cause it's kind of heavy application!) then with this software glitch it becomes even more slow... it's a sort of 3310 with froyo on it! :-(
I've kind of few applications installed btw and NO services started at boot, so i would exclude the cause of 3rd party applications causing this...
Did you actually fix the unresponsiveness? Or just the GPS fix time? I've managed to get the GPS fix to work, but the phone becomes very slow, even after the GPS is turned off.
exactly my problem, the gps fix with the method posted before is really fast!!
The phone becomes slow though, as you said :S
Ok I think I've found the problem. The stock GPS I5800XXJPF actually works really well. With a fresh install, my GPS would lock on for the first time within 20 seconds or so, and the phone would work fine. However, after reinstalling all my stuff with Titanium, the GPS went back to being very slow, and the phone would remain slow (laggy) until reboot.
So... I checked my GPS settings and I had 'Use sensor aiding' checked. Unchecked it, reboot and voila! No GPS problems. I still use GPS toolkit to make the first fix, but that is the only thing different from stock. GPS works great now and phone runs at full speed.
Does this make a difference for you guys?
You're my new hero...this "fix" works and gpsfix it's still fast and stable!

disabled "sensor aiding" on Galaxy-3 i5800
Hi,
I was planning to make a new thread on the lagging behaviour of the galaxy-3 i-5800 when i found this thread.
problem I had for long time :
My phone went to 100% cpu after "closing/ending" an application which uses gps, like g-maps,copilot,lattitide etc. It took me many weeks to pinpoint the problem, when it happened. Reason it took so long is that i found by accident, the 'remedy' , which is switching off the display and switch it on again. This interfered with the root-cause analysis , because when the screen went out automatically, the problem dissappeared :-S
"Finally" yesterday i found the root-cause of the lag.
It was "sensor aiding" in location and security setting. After disabling this setting, the lag problem is gone.
In dutch the setting is called "sensorondersteuning", which is located under "locatie en beveiliging".
So I want to spread the word to many galaxy-3 owners (i-5800/5801) to NOT use this feature (even not in the lates JPM firmware).
From yesterday, I'm a happy galaxy-3 owner again
enjoy it.
its JPF not SPF and its kinda stock like, many stock apps are removed, social hub etc. I dont think any are added, besides superuser since i suspect its prerooted

Are you overclocked?
Whatever this is, it's definitely a hardware issue, not SW

no not overclocked. root is only changes from stock
whatever it is it's only effecting 5 apps, TB , a task killer. rarely.
3 games quite often.
i dont get it. strange
Thinking about flashing ICS or tiamatxoom on this sucker.
while back i got a permissions changing app, because i got alittle tired of so many apps self starting , the app mentioned that certain permission changes could possibly damage my os. Is this true?
also noticed that the ota nagging has stopped
Flash ICS, definitely. But undoing the permissions changes might be the answer. If it was in permissions denied, I know sometimes that can cause problems. Using autostarts has never caused this issue for me.
Yes!
IML77 cured all, and im loving ICS

Re: [ROM][NIGHTLY] CyanogenMod 9 for Motorola Milestone 2 (Android 4.0.4)

Re: [ROM][NIGHTLY] CyanogenMod 9 for Motorola Milestone 2 (Android 4.0.4)
This is kinda sad, that I can't reply directly to the ROM thread, but here it is, I just hope someone will tell them, or see it to adress these problems correctly:
There's a couple of problems with this ROM. First of all it loses the data connection after sometime of inactivity. Browser won't load anything, asking to check the connection. Going to settings -> data usage -> mobile data switch -> turning it off and then on solves the problem, but it's kind of annoying to do that five to six times a day.
Secondly - just after flashing this ROM keyboard backlight was working fine. But after installing the gapps it stopped. Just won't work. ((
Third(ly))) - Apollo app crashes at random when trying to listen to podcast/music from sdcard. Also annoying. Disabling data connection seem to solve the issue tho as it stopped crashing yesterday.
Fourth - some sensor shanannigans when you're trying to use chrome (games are fine with it) while charging. Random zoom-ins and stuff.
Fifth - and most terrifying. Sometimes it loops, as if I was repeatedly taping the screen at the center or somewhere near it. Can't even reboot when it happens. Power button to lockscreen seem to solve the issue.
Otherwise this ROM is smooth and good and I like it a lot. Using it for a few months now.
Big thanks.

The Data connexion loss is a recuring bug for some, mostly people who have a Carrier that use roaming (ie : use another's carrier's network). No known fix for know, but some people seems to have it working "better" by disabling data roaming/national data roaming in options, but it's not for everyone, since some carriers require that to be toggled for data to work.
For the Backlight on the keyboard, be sure to check if the automatic gestion of automatic backlight is activated, it's required for it to work. There is too a "fix" for the problem in the last 5/6 pages of the main topic from memory, but don't recall it exactly, so you'll have to dig to try it.
No idea about Apollo, but it seems to have quite some quirks, and most people use other players so not sure about it, maybe start by checking the Apollo dev's page and market comments to be sure it's not related to Apollo but to the ROM.
The "random sensor shennanigans" while charging is something that happens to a lot of people, i think it's a multi touch bug from the kernel, but not sure (ie : not really solvable by the dev, unless he finds a way to remake tezet's fix (i think it was tezet) or we all use CH kernel since it seems the bug isn't there in this kernel [ wtb a way to use custom kernels :/]).
Your last problem is a weird bug, probably linked to the ROM, but i must admit it'll be hard to pinpoint, since i don't have it but my brother do, while both phones are the exact same model, and flashed the same, in the same order, with the same sbf/rom versions and so on.
I guess you can try to make a full wipe/factory reset (only backuping data you REALLY need to keep like contacts/sms/call log and so on) and redo your phone config, because as far as i know, the only difference between my phone and my brother's is that i had to did that again after i screwed up a couple times, installing an app that was bricking the phone (took me a few wipes to identify it), it might be the reason why i don't have it and he does, or not.

L5 II 3G Data won't connect after wifi usage

First of all, hello ! I'm new around here and I just stumbled upon a problem I guess on my new phone ( the L5 II E460 ) so I decided to ask your opinion on this one cause I don't have that big knowledge about smartphones and androids to be honest
The thing is: Sometimes when I use the wi-fi connection home and toggle between the 3G data connection from once in a while the 3G Data stops working.The wi-fi connects back without no issues but if I switch to data it won't show the 3G sign up or H and I can't access anything unless I restart the phone, then everything goes back to normal ( to be honest this happened to me only twice and I have the phone since a month but it's still frustrating and first I thought my phone may be broken but after a little google search I found out that many people have this problem )
What other solutions are to stop this " problem " or whatever it is to occur again ?
Thanks.
So,no one nothing?

I toggled multiple times just to try what you reported but it didn't happen to me.
Did you update your firmware? I also recommend also a full-wipe:
1 Turn the power off.
2 Press and hold the Power/Lock key + Volume Down key + QuickButton.
3 When the LG Logo appears on the screen, release all keys.
I didn't do any firmware update atm, it's still the Jelly Bean 4.1.2
It doesn't happen often,only from time to time and the airplane mode on and off toggle seems to resolve the problem so I'm guessing there is some problem between the wifi and data settings sometimes.

Do the update (through software update in your phone). It stays at Jelly Bean 4.1.2 it's just an update to it. Maybe it solves your problem, as it may have been a known bug. I've updated and I don't have your problem, maybe it was solved. Also do a full wipe afterwards.
Ditto... almost!

I have the LG-E460 (L5 MkII) and JB 4.1.2 updated to May 28th 2013. It is just 10 days old so I have 4 days left to decide to keep or return. This is my 1st ever smartphone, so I am without any doubt a NOOB in more ways than one.
If I understand correctly, my problem seems to be similar. If I am updating the weather, twitter or facebook etc, using my home wi-fi, every now and then I get a message "Network Unavailable", despite FULL signal on my network, and the only way to restore it is to turn Wi-Fi off, then on.
It seems to work just fine by leaving Wi-Fi off, thereby using the mobile data permanently.
Could this possibly be anything to do with the type of network in use? ie, WPA2-PSK etc?
Regards to all,
Mike

I experience wi-fi connection losses too, but not that often and I can live with it. If it's too often for you, return the phone as it is a bug. Others have reported it too (see the lg uk website for our phone).

This is, sadly, the conclusion I have come to. Apart from this one issue, I love the phone and it was the only unit at this monthly price-point that, in reviews anyway, was any good! The other handsets were Samsung Galaxy Ace, HTC Desire C and Huawei Ascend Y201.
I know reviews are not always the best way to choose but, out of the four, the L5 seemed to be "the one" for me, particularly after reading users reviews and studying the spec. sheets for all.
I'm trying to save money, not spend more, so the L5 will have to stay. Because it is new to me, I'm using it WAY more than is normal, just to get to know it, so in normal use I can probably put up with it.
Thank you for letting me rant on; and thank you for a great site.
Best regards, to all,
Mike

Well, I haven't found a cure, but I have found a way round it!
It would appear to be WPA that's causing the intermittent, but common, "No Connection" message... I changed to WEP and it has now been perfect for over 24 hours.
I think I've got this right: in WEP a "key" is only sent at the outset! With WPA, a key is generated every so often and it must be that which is upsetting the L5 and causing it to "have a fit"
Any thoughts would be welcome... I do know the pitfalls of using WEP, but it has proved a point... at least I think it has.
Regards,
Mike
