Galaxy 3 goes into offline mode by itself - Galaxy S III Q&A, Help & Troubleshooting

Hello together. Since a few weeks i have a lroblem with my SGS3 9300. It goes offline for any reason what makes me lose a lot of calls. I thought it would be the ROM and changed but still persist. All energy saving options have been disabled. I have no clue.

Anyone a idea?
RIght now again, after a few hours without any call it goes into airplane mode again.
Dammit if this continues i have to get another phone

Well, it is a smartphone. It knows what it's doing! XD
Jokes aside, have you flashed any ROMs? If you're on stock, I think it may be your network at fault. I had this happen to me and I was really frustrated with my phone. It turns out that I was having network problems. They were repairing a nearby tower and that was causing my phone to lose all signals.

Did it come back to Online mode automatically or you have to do it manually by going into the settings ?

Weird Problem -- No signal if reboot while charging

My wife's phone has a very weird problem. If the phone is rebooted while it's connected to the charger, the phone will have no signal after boot up. The signal bar shows a cross and the IMEI is blank. The phone is okay if you reboot again without it being charged. I have tried alot of ways to fix this problem including changing ROM (currently on criskelo v38), changing kernel (currently on NEAK v1.3.3), changing modem (currently on XXLPH), wiping dalvik, and fixing permissions. But none worked.
My own GSII doesn't have this problem. Anyone can shed any light on this?
Correct IMEI for phone ~??

Yes, imei is correct during those times the phone has signal.
My problem is when reboot while chargign the phone does not recognise sim network and didnt even ask to input the simlock like normally when I reboot without charging.Maybe this is a bug?

Yah, same problem. As my wife doesn't have a sim lock, so it will show a triangle and that network is not responding or something. But it is perfectly fine on my phone. Is this problem affecting some batches?
Same problem here, I'm becoming mad. Flashing a new rom with no restored apps eases the problem for a little while, but it will do happen again. Restoring efs or changing kernel does nothing... Seems hw problem.
Ps: I also noticed a higher system cpu usage which results in higher battery drain. Phone is still usable but I don't get the same duration off charger as before.
I have this problem too, how do we fix it?

Hardware problem, I had to RMA it! It was amazingly difficult to explain the issue to the poor fella in the assistance point
I also have this problem, I just never reboot my phone when it's charging. It would be nice to fix though.
What's RMA?
Thank you

Random screen touches

Hi,
Since 4 or 3 weeks ago I started having this issue, the phone suddenly seems to be possessed, mostly when another person touches the screen. The screen starts to do random touches everywhere and the phone gets unresponsive, so I have to lock it, and unlock again to solve it temporarly.
The problem first appeared when I flashed Topsmarts ROM, then I flashed Neutrino EE 2.9 and the random touches seems to be less frequent.
Anyone has experimented this? How can I solve this?
Sorry for my ****ty english.
Same here. No idea how to fix this. Doesn't bother me that much, though. Easy to fix by a simple lock and unlock.

Bad digitizer. Seen it in action. Weird, but it happens.

[Q] S3 shut down. Not working after flashing

Hi there! This is my first post here, so I hope you guys can help me. I've posted my question in different forums, but nobody could help me.
So, I was using my S3 the other day, and it suddenly shut down. I tried to turn it on, but it didn't work, so I thought that it had run out of battery, and let it charge. When i pluged it to the charger, I realized thee charging light wasn't on. I tried to get on the recovery mode, but it wasn't working. I was already giving up when i decided to try to put in on download mode. It worked, so i tried to reset it trhu it, but when asking me for mi PIN, the phone would go off again.
I tried flashing a official ROM from Sammobile. ODIN worked well, with no fails, but when the OS was supposed to start charging, when the android whit the blue line appears, the line would charge till half of it, and then the phone would shut down again. I recorded a video, but since I'm new here I can't post it yet.
I tried flashing different roms , even one that had the multiple files in it, but nothing worked. It just stays like that. The phone wasnt rooted, so i tried rooting. The phone did just the same, but when I came to look again the download mode, the flashing counter was on 1, so i suppose the rooting worked. Then I tried to flash a Clockwork to get on recovery mode. But the phone would stuck on the installation and then turn off.
Can please somebody help me?
By the way: the phone only works when plugged to electricity.
thanks on the advange!!

Mmm...I thought about the battery too. Like two months ago, I had to change the battery, because it was inflated becaused of overuse, and the phone wouldn't stop doig weird things and suddenly stopping working. So we bought one in a shop (it's not an official samsung battery). But now tthat you say it, the screen makes the same thing that did when the old battery was on the phone (it starts like trembling and then the phone suts down) so i guess I'll try with another battery. I'll post the changes!
thank you so much

Ghost Touches After April Update

Basically just the title
Can't post links so remove the spaces from this - streamable . com/jnwafk
This started happening after I updated and now my phone is basically unusable. Tried everything I could find online including factory resetting and flashing another countries firmware.
Appreciate any help.
Go to developer options/input and switch off Show taps.

Sorry ive posted on like 3 different forums I should have specified. The taps at the top aren't me they're ghost touches which is the issue. I turned on taps so I could see where they were.
In that case I can't see any issues on the file you uploaded. Can you be more specific?

So basically I try to use my phone and what you see in the video happens. The notification centre scrolls up and down and I can't do anything. What makes me sure its software related is that if I lock and then unlock my phone it goes back to normal for 10-30 seconds before it starts again. Sorry if im not making sense
Well if you have touch sensitivity on disable it. Other than that dont downgrade to an older ROM you will brick the device because this is the only update right now that is on the 8th bootloader. All the other firmwares are on the 7th or older
I have experienced the same problem today where I was using my phome just fine but suddenly the notification menu drop down, I swiped it up but it again dropped down.. it kept happening.. the back key wasnt helping much other.. I locked and then unlocked the phone and its fine since then..
I have S9+ Exynos with April update
