Touchscreen/charging bug - Sprint LG Optimus G

I thought v9 was supposed to fix it, but I'm still experiencing this issue and probably even worse than before. Anyone else still have this issue?
In case some don't know its when the phone is charging and the touchscreen becomes very unresponsive.

Are you running the rooted zip or sprint ota?
Sent from my LG-LS970 using xda app-developers app

Rooted zip. Tried all variants of v9 and still have the issue.

It's because the kernel is what handles the charging I asked a guy who said he pulled a boot.img from V9 ota to post it and I'll check it out
Sent from my LG-LS970 using xda app-developers app

I think its worse in ZV9. So the kernel had to change.
Sent from my LG-LS970 using xda premium

Man I just got the new kernel, its the same versions but they patched it or something because that bug is GONE. Gonna test out some more and post tomorrow if I get time.

I have the AT&T version.
And I can't remember if I read this in the international forum or the AT&T forum, but the bug seems to only happen (for me anyways) if you are using a different charger.
Try the original plug and cable and see if it still works.

It still happens with stock charger but I've noticed it is worse with others.

Ah, well sorry about that then. I was hoping it would work.
I read one of the recent updates for the AT&T version fixed that bug, but I am running an older ROM and can't say if it has been fixed.
I know that doesn't help here though.

Funny i noticed it after the zv9 but its only with cheep crap chargers putting out around 57 hertz not the normal 60 stok charger does not do it for me...

Vulnerable tickets fix Ota

Thanks to Samsung's fast updating now a days, they caught the exploit and are telling galaxy owners to update. I'm glad Samsung is working even harder now to keep its line up safe and up to date. The update is being release over air.

No. They disabled a lot of the dialer codes starting in UVALH2. So the latest official update already had the vulnerability patched. This is often the case when stuff like this gets publicly released. Its usually already addressed. I mentioned it a couple times in the thread someone started yesterday.
As far as im aware the leaks are still 'on hold' for all devices. Still not sure why Samsung did that though!

No there talking about the secure hole the hit the news yesterday, our phone have the fixed but some older phone aren't so lucky, my friends gs3 Is fine too and I try it on stock and it didn't work, so I guess we're safe for now

Just out of curiosity, did you try clicking on a link, or entering the dialer code to test it out?
Im just curious if they actually did disable the dialer code or if they just prevented it from opening by pressing a link.
FYI, I tried the dialer code and it did still initiate the factory reset, BUT, im also running a sort of hybrid, frankensteined rom where ive been playing with different apks from different leaks. I may have changed something that caused it to work for me.
(Im planning to reflash everthing later an will test again anyway, just curious as to your experience). Also what rom and build are you using?

yup, thats pretty much it. Most of the time we wont hear about an exploit or other security flaws until after the problem has a fix. Its just plain poor judgement to basically advertise a major issue before that.

Thanks for specifying that for me. Kinda surprised though since they disabled many of the dialer codes, figured they would've done this one as well. In the end I assumed itd be one of the two, or both. (The disabled codes I keep mentioning are only partially so. You can still execute them via cmd line).

Maybe ZVB was the soak test and ZVA is the final rollout. I thought something was weird today when LG's source code link was down.
It could be like Microsoft where no matter the real build number, it is released as zva. Think windows 7. The final build number was 7600, but the real build would've been 73xx. Or on my epic, they made builds after the official ota, but released earlier ones. No way to know why. Probably some bug.

I'm glad I have Wi-Fi in my house, I'll just bring my phone close to the Wi-Fi router and once the OTA pops up, I'll download it via Wi-Fi.
So... has anyone got this update yet or a way to pull this update from some mystical server to confirm zva or typo?

Unknown for 4G

Precursor: I have tried multiple roms both ICS and JB.
Ever since I rooted GB27 after doing all the OTA after getting my referb I can't turn 4G on. The status goes from Unknown to Enabling back to Unknown. I have 3G just fine, can connect to Wifi just fine, just can't enable 4G. Any ideas? I've tried a couple different things I've found here but so far nothing is working. My next step is reflashing my ROM with no external SD card in.

Have you tried flashing different modems? If you are running GB27, then you have to run a jb modem. But you can't flash modems through mobile Odin, has to be done through pc or cwm.

The modem is separate from 4G. have seen something like this before and it was a hardware issue... Another instance was because of a virus protection app that was installed on the users device.

3G/H+ issue in AOSP ROMs

Hey guys, I guess this has been reported before but I've never seen solutions or explanations for it. On AOSP ROMs, data works when it displays "H+", when its in "3G", it stops working, but thing is, sometimes I have to turn off data and back on again for it to work properly because it stays stuck in 3G

You can use it, though it hasn't been updated in a very long time. Only thing we know of so far for the md5 heat issue is to use a different modem.
You can flash any modem as long as it is for your model.

I'm currently running the note s4 rom. My phone will randomly lock up and get terribly laggy. I was on the newest stock ota and decided to flash the note s4 rom. The phone still acted like this on the stock rom also. I've still got lag and freezing. Any help would be greatly appreciated.

Try to do a clean wipe and clean install again. It might help with it being laggy. I usually do a full wipe and clean install every 2 months, even when using the same rom, That's just me.
POWERED by the MASTER!
Ive tried odining back to complete stock and wiping everything and then flashing the rom. It seems to do it at random. A reboot seems to fix the issue for a few hours. It's only done it once or twice so far today.
