Reception Issues

Hi guys, anyone encountered any reception issues? My device is stuck on 4g, when drops goes GSM and data will go away.. But if i flash without CSC i've no more this problem, but still poor reception.

Any ideas to improve this?

All of a sudden I've lost 4G reception! HELP!!

Hi All,

First time poster with an unusual problem. I live in Australia and have a Samsung Galaxy S5 SM-G900F which is the European model. Up and till recently I was getting Telstra 4G reception. Now all of a sudden I'm only getting constant 3G reception. I have confirmed that there are no 4G network repair/maintenance/upgrade issues in my area. It was only in the last week that I noticed the constant 3G reception so I can't really pinpoint a specific incident or exact date as to when it actually started happening. Here is what I have tried thus far:

Phone restarts, changing network settings and switching to flight mode.
I've confirmed that the phone network is set to LTE/WCDMA/GSM (auto connect).
I have done numerous hard resets, cache wipes, Dalvik cache wipes, drive wipes, etc.
I have rooted and unrooted the phone numerous times.
I have tried several different stock and custom ROMS.
I have tried a 4G SIM cards from other phones.
Tried numerous network switching apps.

NOTHING WORKS!

I always love to tinker with my phone so I'm always looking for ways to improve the phone's performance. It may be that an app (battery improvement/tweaking type apps) I installed somehow changed the network settings but I would have thought a million hard resets would have sorted that all out but apparently not. At the moment I'm running a rooted stock Android 5.1 ROM. I've tried stock Android 4 and 6 as well with no joy.

Here is the unusual thing. When I put in another 4G SIM card into my phone the network still remains on 3G but as soon as I put my SIM card back in 4G magically reappears. It's bizarre. At least I know my phone can still get 4G. You would think that would solve the problem but it doesn't. When I am in an area where the 4G signal is weak the stronger 3G signal kicks in as it is supposed to. When I get back into an area with strong 4G reception the phone remains stuck on 3G and no matter what I do it won't go back to 4G unless I go through the convoluted process described above.

I am all out of ideas. I think I have tried everything possible. I've trawled the web and I appear to be the only person in the world with this problem. I don't know if it is a software or hardware problem with my phone. My SIM card works in other 4G phones so I don't think it is part of the problem. At the end of the day it's not a big deal as 3G is fine but I'm just one of these people that has to fix a problem. Worst case scenario I'll probably upgrade the phone in the next 6 months.

Any suggestions or tips other than what I have listed above would be greatly appreciated. Thanks in advance.

Bulky :D:D:D

Wifi reception

I have fairly poor WiFi where I live to begin with.. But my OP3 gets half the download speed of my iPhone 5s and the 5s actually loads pages and videos faster than it.. Is there any way I can improve the speed of the WiFi? Could an update fix this, or a custom ROM?

Poor Data and Cell Reception S5

I have an S5 that when next to 3 other phones in my house receives no signal (data or cell). I have to walk completely outside and its still spotty. Could it have bad antennas? and if so is it just the wire antennas or is there another piece that receives signals?

Past history: stopped using this phone probably 8-12 months ago because of this problem and now just did a factory reboot and re register on the network. and up until the factory reboot the phone wouldn't even register itself on any network or connect to any service even though it showed signal bars. It would either start to make a call and long pause and hang up or just go straight to an "emergency calls only" pop up. When looking on the about phone and status page there wee no registration on the status page.

Joying JY-UL135 Poor Radio Reception

Anyone else have poor radio reception with the Joying JL-UL135? Previous radios in my 2001 Suburban picked up local stations just fine. This one has a hard time picking up even local stations. I double checked my antenna connections and even bought an amplified antenna. No change. In fact, the radio reception is exactly the same weather the antenna cable is plugged into the back of the radio or not. Is it possible the radio antenna port is not connected internally to the radio?

For reference, this is my radio:

Reception cuts out

Can someone help me figure this out...

Whenever I install a new Stock ROM (eg. v20E, v20F, v20H etc) on my LG G4 H815 I seem to have a problem, where after rebooting the handset (or even after turning it off then on) I type in my SIM PIN code, the phone switches on fine but 10 seconds after that my reception cuts off for about 30-40 seconds, then comes back on.

NOTHING else is visibily affected, everything else seems fine.

The ONLY exception is my ORIGINAL stock ROM (H81520D_00_0115.kdz). The reception cut off bug(?) isn't there.

Is there anything I can do to stop this. I am currntly using H81520d_00_0620.kdz and even this ROM has the issue. I'd like to stick to it as it has the latest security patch, but its annoying every time I reboot, I can't make calls or send SMS straight away.

Unlocked T-Mobile Data and Reception Dropping in and Out

I picked up an unlocked T-mobile G5 and I'm using it for AT&T... The rep at the store applied the APN setting for ATT but I noticed after I got a new SIM installed and went home the reception and data connection started dropping in and out.

Basically, when the phone is sleeping and then I wake it starts searching for network then gets reception then get a signal for a couple mins then drops again and searches. Since it's a T-Mobile phone on an ATT network is there certain settings that I need to turn off like VoIP, WIFI calling etc? Any ideas?
