3G Problem (doesn't work till reboot) - Galaxy S 4 Mini Q&A, Help & Troubleshooting

Hey,
I just bought this phone yesterday (got it for like 20 hours now), and this morning i went into the train going to college, and about 15-20 minutes later my 3G connection was suddenly gone..
I tried turning mobile networking on and off multiple times, but that did not work. Then i did a reboot of my phone and it suddenly started working again
Anyone else also having this problem/bug?

Hi,
maybe it was becouse you were in a train? I have a sgs2 and my girlfrind now has a sgs4m and we both have problems getting g3 in trains sometimes.
till now my girlfriend didn't had such a probelm, if it changes I will tell you.

[Q] desire sometimes gets stuck on edge

I have an interesting problem, I couldn't find this issue on anywhere else therefore I wanted to share with you;
Sometimes after 3-4 days usage (in this time period sometimes I use wireless, sometimes 3g or sometimes turn off the connection), my phone gets stuck on edge connection and never goes to 3g unless I restart it.
I tried switching air plane mode on/off and several other things. Only restart fixes this. This is not a new issue, it is happening almost for 6-7 months (on 2.1 and 2.2). It doesn't matter much to restart in a few days but I wonder anyone else has the same problem.
Am I the only one ? surprised

[Q] Wife issues just recently started on SM-P600

So I just purchased the tablet brand new about 2 weeks ago. Love it for the most part!
Over the past couple of days though, the wifi has really started to act up, and it's passing me off.. About every half hour or so, sometimes longer, sometimes shorter, the wifi will just stop working for a while. The bars will still be there, as will the little "download" and "upload" arrows lighting up as though data is still being sent and received. However, the wifi just isn't working. Pages won't load, speed test . net app won't work, nothing requiring wifi.
I usually have to go into wifi settings to disconnect and reconnect for it to start working again.
I haven't done anything different to my wifi router, and my other wifi connected devices don't seem to be having any trouble staying properly connected, so it doesn't seem like it'd be an interference issue.
Can anyone provide me with some help?

Wifi slowdown

Last couple weeks I've had an issue will my Internet connection gets painfully slow over wifi. Today it would give me decent results on a speed test, but would take forever to start running test. Chrome, Facebook, etc, would be really slow to load anything. Similar thing happened last week, except that time speed test came back really slow.
Both times a restart fixed the problem.
Any idea what could be causing this? Before these two times, I never had any issues and never rebooted the phone except if the battery died. I was up to 15 days without any issues and no restarts. Now I've restarted twice in the last 8 days to fix a problem.
I'm following the post closely.
I have similar issues and at first I thought it could be my wifi modem. Restarted that and it seemed to work for a couple days then the same issue. Major slow down. I tested other devices that I have connected to my wifi, none of which have duplicated the major slow down of the wifi. I have done the update and I'll post in a week or so if this has fixed the issue.
I know it wasnt a router issue because my friend has a note 4 and didn't have any issues while I did.
I did a factory reset this morning, will see if it happens again.
I'm also curious about this. Is your wifi AC enabled?
Same here, slow slow slow. My nexus 7 works fine so it isn't wifi.

Did that help?
I'm going to take mine to the At&t store this morning. Facebook just sits there and does nothing, Instagram is the same can't receive email either and that's after doing a factory reset.
I took it in and they are now sending me to the device support center. The rep couldn't get it to hook up with there wifi.
Thanks for the update. Mine isn't quite that bad. It'll just slow down to about 5mb/s while the other devices on the network are fine

Have you tried to turn off WiFi power savings off. You do that from the dialer, *#0011#, go to wifi settings and turn it off. It's known to samsung phones to cause issues with power savings on.

Turned it off. Will see if that does anything.
Hasn't happened in the last week.

Not seeing much of a difference in a speed test. I'm at the outer edge of my wife network, and I'm seeing 10 down /5 up. If I go right underneath my access point, I'll get 50/20.
I take it back, I got 10/5 under the router, while a wired connection got 40/10.
Gonna restart the access point and see what I get.
An iPhone 6 just did 15/1.5
Another test for me and I got 8/6
Restarted the phone and got 20/4.
What is causing this?
Same issue for me as well. It's only the wifi on my phone and it just started last week. I even did a hard reset to fix it and no luck. It's laggy as hell now and I just leave it on LTE so I don't have to wait so long. Any updates?
My issue is worse than it ever was. Instead of happening every 6-7 days without a restart, it happens after 1 day now. It's not so much that WiFi is slow, it's that it takes forever to start downloading and for Web pages to load up. 30-40 seconds before a page will begin to load.
I have a replacement phone coming from att today.

[Q] Random freezing, rebooting, non-responding apps

Hi,
my P6 started doing...stuff... literally over the night. My baterry died after a long day three days ago, so I plugged in the charger and switched the phone on. Ok, but then it rebooted once or twice, the camera stopped working (it works, but there are no controls at all, just the nav. bar). Later almost every app started doing this - I launch one and after 5 seconds of being frozen it says "The app is not responding", so I shut it down. And sometimes it even reboots itself, or just shuts off and I'm not able to switch it back on for a minute or two. And one more, when I'm typing, (if I am able to get the keyboard working), the screen goes black and then on again by itself.
Which is interesting, I plugged the charger yesterday and after three hours or something I was able to work with the phone normally. Some time later it went ****ty again.
I'm now running the B707 firmware, repack for Europe. for two months and a couple weeks.
Have you experienced this before? Could you help? It's Easter time so I don't wanna run to the repair shop right away, they wouldn't care untill Tuesday, anyway -_-

I can assume, that this is because of the unstable B707 firmware. I can suggess you to to instal and try B708 Re-Pack by BbN - it is based on the STABLE B708 firmware and it is repacked for international use. Very stable rom - I am using it one month until now and have no problems with it!!!
Ok, I can try that
Didn't help :/

Phone freezes/crashes randomly

I've had my G4 for a few months now, never had any problems until recently. The phone just freezes, sometimes just a 'normal' freeze, sometimes half of the screen turns to black/noise. Occassionaly it reboots on its own, but most of the time the power button doesn't respond and I have to take out the battery.
The freeze occurs at any given point, typing a text, being on FB, playing a game, ..
Last sunday I did a factory reset and everything worked perfectly fine until today..haven't installed any new apps or anything..
I hope someone can help me.
Cheers.
Now it's just freezing/restarting every two minutes or so..

maybe its abou to get the infamous bootloop.. need to send it to LG to fix.
Mine did that and went into the bootloop a couple of hours later. It now is at a LG partner for repair. Better safe all data you need right now, just to be safe.
