Network Connection problems - JiaYu S3 Questions & Answers

Looking for a little advice/assistance please.
Have flashed RC 5 ROM onto my Jiayu S3. All is looking good. WIFI, Bluetooth and SMS working fine. When I try and make a call and press send the signal indicator goes from medium signal to nothing with a cross and the call does not go thru. When you try and call the phone you get message that it is turned off or out of range. The signal indicator eventually comes back to showing medium signal again. It also seems to jump between 3G and 4G a lot. Every now and again it will work but takes a while from pressing send until it starts to ring. My IMEI numbers are correct. The SIM works perfect in my other phone which is a stock Samsung.
This problem happens in either SIM slot.
Hope someone can help. Tks Ken

call does not end automatically

sometimes while speaking to someone the sound of the 8525 goes blank and i am unable to end the call and the timer keeps running till eventually it ends by itself usually a min or minute a half after. this occasionally happens also when the person on the other line ends their call.
help me!!
oh yeah, when it ends call, i lose service and i have to wait for the phone to pick up reception before i can call the person again
I am sure that one of the more experienced members may have a better idea, but I had this problem in low signal areas when I was on radio 1.34. It stopped happening when I upgraded to 1.38 and so far hasn't happened on 1.40.
Something to try anyway.
This happens to me quite frequently in my house!!
Next time this happens notice if the network indicator has dropped from U to G during your call. When it happens on my 8525, the call wont terminate. So many times while im in my house ill band tab switch to GSM just so it does not do this..
I had one go for 63 minutes in my pocket once... so i checked my usage, and it was only shown as the 2 minute call I actually had. So it did hang up from the network, but my phone was blissfully unaware. I'm not so sure however if someone else called it would have rung.
Hope this helps, let us know if it's changing from U to G !

Seems like you have the same issue I had at work, two low level signals and it hangs trying to switch between continually. Has upgrading the radio helped you at all, or was it just coincidence for me?
im currently on radio 1.38, maybe if i switch over to 1.40 ill see, but i will def keep tabs if the network goes from U to G.
thanks for the help guys i switched my network from "any" to "gsm" only, and so far so good, i guess the problem was when the network would switch over from gsm to wcdma im not totally sure. anyway i chose GSM as the network it should always be on, and the network indicator always has an E on the top. is it fine if i keep it at GSM or will i run into problems/ or not recieve full benefits of something? some1 please educate me thanks

Call Drops

Hiya
I've been getting a lot more call drops than usual recently.
Trying to make a call, I get a long pause with nothing at all then 3 pips/beeps as it drops the call. It takes about 5-8 redials before I can get a line out.
There is no difference either if I do a soft reset Reluctant to do a hard reset but if I do I'll try and backup first.
Then there are incomming calls. It misses them, or there are times when people calling get a long tone but i see their number flash up and it just drops the call and I get a missed call alert. Calling them back gives me.... the three pips
I can't win. I've tried screaming abuse at the phone but strangely enough it has no affect
Seriously considering ringing Orange tomorrow to see if I can get a replacement... Grr.
Suggestions anyone??

Sounds like a network issue and is probably down to your local 3g cell (either being just too far away or having other problems). And yes you might have two bars or whatever on signal strength but 3g can be problematic like that.
Try settings, phone, band, and changing it from Auto to GSM. This will force your device to use gsm instead of 3g. If that improves things, try switching back in a day or two to see if they've fixed the cell.
I'm in the city centre almost and from my flat I can see at least 3 seperate towers. Of which i know 2 are Orange
Thank you for your suggestions, I will try that later.
This problem though doesn't just happen at home I think I'll have to dig deeper...

Big Issue - Can Make Calls But Not Receive

I have had a wizard for about a month now with few issues. After the first couple days I settled on Jaguar 4.0 ROM, and it has been working great except for a few times when it freezes / won't let me unlock the screen to use it.
However, the past few days a big issue has come about. I can make calls easily, but I cannot receive them. People say it goes straight to my voicemail. My phone doesn't ring, doesn't tell me I have missed calls, doesn't tell me I have voicemail.
Last night I found one thing that may be part of the problem. On the top, it shows the network strength - this is always strong. To the left of that, it SHOULD show an 'E' symbol, possibly for the edge network (at&t) ? Anyways, I know the E is there when it works. I can also connect to internet via GPRS when this is there. Lately, that E symbol no longer shows up. Intead, it has a different symbol with an 'x' on it (two arrows in opposite directions with a small x). At first I thought this just meant I wasn't connected to the internet for data usage at that time, but I've learned that I cannot receive calls either. If I try to connect to the internet, it says connecting but never connects.
If I click around in the menus and connection menus, or reset the phone (sometimes), eventually I can get the 'E' to show again and the phone is working like it should (not sure how to actually get it back, but after clicking around in menus I can). However, it doesn't stay. It seems to stay on a few minutes, I think everything is ok, and then I look at my phone 30 minutes later and that symbol is gone, thus I am no longer receiving calls.
It's weird, because I can make calls easily regardless of the symbol there. I'm clearly connected to the network, have a signal, etc. I've checked flight mode, which is always off. I've checked settings and everything looks ok.
Any ideas on what is going on or how to fix this?
Edit: Note - Turning flight mode ON and then OFF seems to get the E back and the connection restored properly. I think the same happens by turning the phone OFF then ON. However, it only stays fixed temporarily (less than 30 minutes) and gives no notice the proper connection is lost. I just find out next time I look at the phone and see it's not working and find out I've missed important phone calls.

Connection issues

Tmobile is very spotty at my school, i go to FAU in Boca Raton Florida.
a lot throughout the day i ll loose sign and then it will come back once i put the phone down for a few seconds but then i will loose connection, the phone will tell me i got EDGE or 3G but will not make calls, send messages or go online??? its weird
if i try to put it on airplane mode it will just have the bars as normal but no G, E or 3G logo next to it
either way if i just try to restart it or put it on airplane mode then restart it, the connection comes back normal.
anyone else experiencing this issue?
I am, and part of it has to do with the phone cupping thing, i feel anyways. I have tried sending text with the phone on the counter (not in hand) when the signal appears stronger and it still wont...
Soft resets help me, but what a PAIN!
ok good, so its not just me!!! well them its probably a software issue... we should let that be known to the BIG G so may be they could hopefully work on it in the future!

Nexus 4 - signal/data connection issues

Hi there, I've had my nexus 4 since the day it launched and had no problems its been a brilliant phone!
I accidentally dropped it while replying to a text in the bath(stupid I know!) Was submerged for about 2/3 seconds at the most. It did have charging problems and speaker was cracking, since left it in the drawer for well over a year now, recently gave it another go with my current o2 sim card which works no problems.
It does display full signal, sometimes shows E connection & sometimes shows H connection although it doesn't let me ring out nor sends texts.
Under status info in the settings menu it shows everything as normal, tells me my mobile number, service status, signal strength etc but still won't let me ring out or send texts.
Everything else on the phone seems to work fine, WiFi connects and loads pages/play store etc. Speaker seems to work fine again.
Just wondered what I can do to get texts/phone calls working again?
Andy.
