Bad Reception with this phone?

Hi,
Was wondering if anyone got bad reception with their phone. I tried 3 different carriers since I had my ideos, in neither of them I ever had very reliable reception and lately the problem is getting worse. I'm running aurora 4.1a and I loose reception all the time, and the battery drains so quick because it's always looking and looking. My sister, my mum and my dad all have good reception (2 of them with my old carrier and 1 with my current carrier).. I can put my dad's phone (same carrier) next to mine.. he will have full bars with 3g and I'll have no reception at all!!!!!! Then it connects and disconnects again, and so it goes... Anyone having such issues?
Thanks.

I'm having the same problem, I'm running Aurora ICS. I use to always have good reception everywhere, Then suddenly I've just been unable to. Any help would be great! If I do find out any fixes to the issue myself I will sure let you know.

Good to know that I'm not the only one! Thanks. Hope we find a fix soon.

I've fixed mine now, What I've done is I've gone into Settings > Wireless & Network > Mobile Networks, and scrolled all the way to the bottom, and simply re-registered on the network and selected Use only 2G Data. Mines now working fine with full connection everywhere. However I don't know if our problems are exactly the same, however this is what fixed mine. Sorry if this doesn't help.

I have the same issue. Mine connects to 3G and has good connection, but then it simply disconnects and moves to 2G or reconnects to 3G some time later. That happens pretty frequently and I thought it was an issue with the carrier, but now I am not sure anymore.

Blefish, that is EXACTLY what happens to me, and I tried 3 major carriers in Australia (the only 3 that have their own actual towers). Just after I posted this thread, I happened to do the same thing as IwAsBlack recommended and... so far it seems to work. I have generally better connection and I haven't seen that ugly no reception icon since! Of course, internet browsing will be generally a bit slower but then again, it's better than staring at the phone for 3 minutes until it reconnects just to open Google.

You haven't stated which model you have. I got rid of a Motorola Bravo for at U8800-51 and I have excellent performance over AT&T (US). Crystal clear even with only one bar and I have never had a dropped call.

Have the same issue on any ROM with any mobile network in Belarus. Can't use 2G as recommended above 'cos of a huge use of mobile internet for some net-radio.
Sorry for bad Eng.

Its a U8800 Q&A forum, I didn't think that I had to state the version since I have a U8800.
Yesterday I tested and kept an eye on for the whole day! The reception since changing to 2G only has been AWESOME! Only had a drop out when I was in the subway (of course!) but aisde from that, I had amazing reception not to mention.. that my phone lasted the whole day with still 15% left!! (3G on, it would have to charge it twice while I'm at work) So, it fixed my reception AND my battery problems.

FYI, Ideos X5 U8800 describes four different models.

I know it does. What I meant is that I have the Normal U8800 model, so I didn't feel like it was necessary for me to point any variant model number like PRO or 51 or H, because it's STANDARD U8800

So we can make a conclusion that U8800 does not operate well on 3G. I can't switch it myself because I want to use internet too. And I am pretty sure we can't do anything about it, no matter if the problem is in hardware or software.

Mate, if you switch to 2G you will still be able to browse the internet! It will only be a LITTLE bit slower, better than having constant disconnection!!! I constantly use the internet to sync my gmail, send free texts, browse the net and a bunch of other stuff.. works even better on 2G with constant reception, not to mention the benefit of the phone battery lasting a whole day (AND still have internet).. so switch to 2G and you will like it... still good internet only with better reception

Same issue
Having same issue when using GSM/WCDMA auto or preferred modes. works normal on GSM network only.
Even when I have no signal of 3g, gsm is working in the background.
problem arises when I have a call, 3g signal drops to minmimun, after the call phone tries to reconnect with the 3g signal but drops the GSM signal in the process.
Try this , as soon as you disconnect the call, try to call yourself from other at that instant only. Your phone will be shown unreachable because phone drops the GSM signals.

4G Problems with D802 (3 UK)

Had a Nexus5 that performed flawlessly on 4G, but wanted/needed the extra battery of the G2.
Bought an unlocked new D820 G2 from Ebay UK. Phone is great except for 4G.
Firstly, it defaults to GSM/WCDMA. I can change it to GSM/WCDMA/LTE auto, but every reboot will reset it to GSM/WCDMA only.
Secondly, when connected to 4G, any incoming call goes direct to voicemail.
Thirdly, when on 4G and making a call, it first drops to H/3G, then loses all mobile internet, and when the call starts to dial out, reconnects to H/3G (but never 4G). Afaik, the D802 G2 should support SVLTE?
I can get into the service menu, but when clicking LTE-Only I get "not supported".
Any ideas what the hell is going on?
The software version, baseband version and firmware version all check out as being UK/up to date - and the phone hasn't been rooted or tinkered with. The SIM is the same 4G SIM that worked fine on the N5

Any reply on this issue?

Reception Issues

Hello All,
I use VZW variant VS980.
I came from a Rezound and never had issues dropping to 3g at home or work (I always had good 4G coverage). I have been trying different modem/radio versions (10b, 11a, 12a, 12b) but it just seems that the G2 does not have a great antenna. Or is there something I can do to improve the signal strength and stop it from dropping to 3G? Also, sometimes it appears the only way to get it out of 3G is to reboot or go into airplane mode and then turn it off.
Any suggestions would be appreciated!

[Q] How can I fix my note 3's signal reception?

So... my Note 3 is like new, no exterior damage at all, I've taken well care of it, but I'm having some problems with signal reception.
Using LTE/GSM/WCDMA mode (or LTE preff with CM based roms) where the phone prefers 4G signal, I have 1 or 0 bars of signal, I miss calls and texts and web browsing using data is really slow!
Using GSM/WCDMA (3G mode in CM based roms) I have like full bars but slow internet using data, I don't miss any calls or texts (at least I didn't notice it) but when I am in the train and I pass through a tunnel, the signal is lost and it never recovers, I have to remove my battery and reboot the phone to regain signal (my other phone, a Galaxy Nexus, loses signal only inside the tunnel, then in seconds it reconnects again like it should, I also have full bars everywhere and no problems with the same SIM card, I also have an LG G2 at home and LTE works very well with the same SIM on that phone, it's just Note 3 that has really poor or no reception at all).
I don't think this is normal and I don't renember having problems like this in the past, how can I fix it? Please help me since I can't find any info by browsing and everyone knows Samsung isn't cheap when it comes to fixing things with knox 0x1, and I am fine fixing it myself if I know what to do.
Do phones use different antennas for LTE and 3G/2G? Is it an antenna problem? How can I pinpoint the problem? How can I repair it?
Thanks in advance.
EDIT: forgot to mention, I've tested this on many custom roms (CM13, CM12.1, RR, N5 ports, S6 ports, Aryamod, Stock Samsung Lollipop, Stock Kitkat) the problem is the same everywhere so I think it is hardware problem.

Call/LTE issues on H918

Hi everyone. I decided to root my H918 from 10t by using lafsploit. At this time, my calls, LTE, and SMS were all working perfectly. After downgrading to 10p and unlocking bootloader, the device had difficulty staying connected to a single tower. it kept dropping signal often and was not able to make outgoing calls or stay connected to LTE for too long. After this I flashed LineageOS 15.1, not thinking much about it. On LineageOS, every time an outgoing call was made, it would drop the signal for about a minute. If no calls are made, LTE and SMS sort of work. I flashed 10u stock after that with Magisk and the phone has difficulty connecting to LTE or making calls/sending SMS. I have tried the following:
- Reboot
- Clean flash
- Format where you type "yes"
- APN settings
- Network mode change
- Airplane mode on/off
Somehow after a reboot (on Stock 10u zip) I'm able to make 1 or 2 calls and then it stops working. I called the carrier and they said there are no outages in my area.
I put my SIM in another TMO phone and it worked perfectly. I put their TMO sim in my phone and it had difficulties making calls. So the possibility of it being a sim issue is ruled out most probably. I have been recommended by a few people to try and flash an h918 modem but 1. Not sure if it is safe and 2. Not sure where to source it from. I have no other ideas and this is my primary phone so I'm having difficulties without a usable phone. Any suggestions would be hugely appreciated. Thank you.
Update: Tried flashing to 10p kdz from download mode but didnt solve anything.

Is the wifi also on?

I'm having the same problem, but was running on 10j. I went back to stock and upgraded to 10u to see if it fixes the signal problems I have with this phone. Both Cell signal and GPS on this lg v20 are horrible. On using the h918 on at&t. If not, i will either need to go back to my moto x pure or maybe buy the international note 9 with the unlocked bootloader.

The Wifi is on, but I also tried with the wifi off as well as turning off wifi calling, Volte, etc.

I tried the same. Just flashed a 10p kdz to see if that would fix it, but no luck. Same issue happening on complete stock OS..

I replaced my sim yesterday, but that didn't make any difference. Before that i replaced the plastic bits on the top and bottom of the phone where the antennae contacts with.
I went back to 10j yesterday which was still arb0 and now upgraded to 10u which is arb1. I'll miss lineage, but i was just having too many problems with it. Not sure what at&t has on band 30, that's the only band this phone is missing. I regularly was losing signal while just driving on the freeway.

Hello. I have the same issue on LineageOS. Been trying to fix it but no hope. But I did find a temporary solution. Let me describe the problem. I'm having a LTE sim that works just fine, then it just stop working. The problem is when you enter an arena without LTE or the LTE is too weak at that point then your cell signal is laggy and lost completely. But you can switch the Preffered Network Type in the Settings to WCDMA/GSM/CDMA and your cell signal is back. That's my solution for now. Hope It helps.

With a custom rom, you can't have wifi on with data on. Simply turning wifi off doesn't fix the problem. You would need to reboot. This has been a problem from the beginning. It works with a totally stock phone, but beyond that, no.
Here is the only way to keep data calls working properly: If you need wifi, turn on airplane mode, then turn on wifi. When you are done, turn off wifi, then turn off airplane mode to bring data back.

Not sure the signal is any better with the new firmware on 10u, but at least my location services is behaving better and the camera actually works in stock. I did a side by side comparison of the gps signal with my moto x pure. Side by side the moto x pure got to an accuracy of 10ft with 21 satellites in view. The lg v20 locked on much slower to 8 satellites with an accuracy of 50 ft.
For comparison -
satellite 14 signal strength
moto x pure 34
lg v20 23
the cell signal may be better with fewer drops, but in some places without lte the speed and throughput is miserable.
