A50 Network problem in low signal area - Samsung Galaxy A50 Questions & Answers

While using the phone in an area with good signal coverage, it works fine.
But when the signal levels are relatively low, the mobile data doesn't work/ terribly slow.
Compared this with some Nokia and Xiaomi midrange devices with the same sim (LTE enabled, same apn) but they worked without any issue compared with this.
Anyone experiencing the same issue??
Is there any way I can tweak/fix this??
(Samsung forums suggests resetting phone and it didn't work for me)
P.S : I am using the Exynos model (SM-A505F)

Tab S 8.4 LTE SM-T705 random disconnects from mobile network

Hi
Anyone else get random disconnects from mobile network? My device says H+ has a good signal but can't transfer data. Enabling/disabling flight mode fixes. I believe it's linked to cell handover or LTE <--> WCDMA handover. Does not do it if device is stationary. Sim works fine in my xperia z3, likewise sim from Z3 (different network) has same issues when installed in TAB S.
To complicate things, I have also seen issues with BT tethering, using phone for data transfer when device in this non working state. Again, in/out of flight mode fixes. WiFi works just fine.
Device is latest stock firmware, not rooted because I like OTA, and have no time to fiddle these days.
Just switched it to WCDMA-only for a test tomorrow. I commute same route by train each day.
Really annoying. Afraid tab is headed for fleabay if I can't solve. Beginning to think it's a designed-in Samsung issue. [emoji20]

I am experiencing the same issue with my LTE signal. it says 4g with 2 bars of signal then suddenly the arrows stops so transmission of data also stops then airplane mode sometimes no longer work. i would have to put the device to WCDMA only then back to LTE.. I can force my device to use LTE only bad sadly the signal drops almost 1 minute after connection
Is your device exynos based or snapdragon. There are two variants doing the rounds with the snapdragon only in the US. On exynos based devices, an Intel LTE chipset provides the LTE connectivity. I believe the US version uses the (faster and better) snapdragon due to a lack of LTE band support in the frankenstein exynos/intel solution. I wonder if the intel lte chip does everything or if the exynos is left to do 2g/3g?
I have disabled 4G on my tab s and the random disconnects appear to have stopped. Did not buy a 4G tablet to have to disable 4G to make the ruddy thing usable though!
Device is also very jerky in comparison to my snapdragon based phone. Not enjoyable to use really. Prob due to all the junk (touchwiz) that samsung shove on it. Its a huge shame because I love the design and build of it, as well as the elegant way in which the stock cover attatches. Good hardware let down by very poor software for the most part.
I think i'll give up on it as a bad job, shove it on ebay and buy a Z3 Tablet Compact instead which is snapdragon 801 based.

*#0011#* Service Mode SM-T705
Hi
Been fiddling with band settings in the service menu in order to solve this issue.
See: http://forum.xda-developers.com/galaxy-tab-s/help/unlock-aws-tab-s-8-4-lte-t2860001
I have disabled the 2G,3G and 4G bands that my network does not use - at least it will save the device from hunting for stuff that it is never going to find. Of course, it will need to be re-enabled when I go abroad.
Will see if it makes any difference. One thing it is useful for is preventing the device switching from LTE to 3G where the LTE signal is marginal, and the 3G signal strong. Just disable the 3G band, and the device is forced to hold onto the LTE signal. Its also useful if you have a tablet and thus find 2G useless. Disable all the 2G bands and the device is prevented from connecting to 2G networks. It will then hold onto that 3G signal as much as possible rather than dropping down to a stronger 2G signal.

I have the exynos version of tabS 8.4.. this fooled me when I bought my device since I was hoping for a Snapdragon version.. but too late. I had to live with this.
what I normally use is *#2263# same with my galaxy note3.. I disable the wcdma and gsm. so forcing the device to LTE only. but this problem is that data transmission drops frequently.
when I tried what you said. signal seems to be better.. I'm still testing it out. thanks for this!
*update. same problem but less frequent.. so still crap:crying:
Guys
Possibly related is the S5 DUOS phone is also reporting issues with dropouts on LTE.....users are having to reset or enter Airplane mode to 'reset', could be a common chipset/firmware/modem issue perhaps.
So... I fixed my issue by buying a Sony Xperia Z3 Tab Compact.
Superb device, and so so so much faster than my Tab S + battery lasts much longer. Not had it long, but some initial thoughts here:
http://forum.xda-developers.com/showpost.php?p=56721334&postcount=11
Tab S 8.4 LTE (Exynos version) on fleabay soon!
Rather expensive mistake, and my final Samsung device for a while I think.
Nigel
it's a LTE band problem ; this is how to fix it
hello
first before u do anything , you have to look for the LTE frequencies used by ur provider , for example here in Morocco my provider Orange works on 800Mhz , 1800 Mhz and 2600 Mhz , which i LTE B3 ,B7,B20 .
So , i had to select only those bands only in the service menu (*#0011# : Back Back /UE setting & information/ Setting / Protocol /NAS/Network Control/Band Selection/[1] LTE BAND
All you need to select in the service menu is the Bands used by ur provider to avoid lost of network by ur Tablet when it s switching between bands which causes rebooting everytime .
i hope it works for u , because it works just fine for me

[Q] d686 Signal Issue

I have purchase d686 from online store but i have serious signal reception issues with this mobile.
1- In outdoor Network reception is around 5-10 dbm less than other mobiles. But the real problem comes when i am in low signal areas. This phone will disconnect all of sudden after -95dbm. while other mobiles are still locked to network.
2- The wifi reception is poor as compared to other phones
I want to know if this problem is related to hardware or software.
Also if you guys can suggest some solution to this problem from your experience it will be very helpful.
Note: I have reflashed stock kitkat roms by lg flash tool but there is no change in situation.

WiFi signal issue is terrible,any fixes?

Hey guys.
Purchased it today,and just like every damn Samsung phone and tablet they still haven't fixed wifi strength signal with even such expensive phone.
So I was out of town and from like 7 wifi signals,only 2 were recognized.
And even when it connects the signal is so weak and it often drops.
Now I'm in my room now and like 3 feet away from router and I'm getting around 6.7 MBps speed instead of between 9-10 just like on my good old S7 edge.
I can't believe.
So is it my phone or others have the same issues?
I have never had a single issue regarding wifi signal strenght, I got my note 10+ since Sept 2019
So I came today in city park,sit on bench and turned ON WiFi on this phone.
Damn,it couldn't find nor any fi..ing single network over WiFi.
I rebooted it like 5 times and then it found one network and barely connected to it with very low signal,but in a matter of minutes it droped.
I had near me,Ulefone 5S which is 200 euros phone and it had better WiFi signal and found at least 5 networks,although with very weak signal,but Samsung couldn't find nor one WiFi network.
Because I purchased used phone ofc I can't return it or RMA it.
Am I the only one with this issue,and how do I resolve it?
But if I'm like in a caffee where is near router the signal is okay,but when I'm outdoors I have this issue,means far away from caffee routers.
Ok I did test outdoors compared with S7 edge.
Do you notice any difference,in terms that N10+ has some issues:
So there is one place in city,where there are lots ofi wifi networks but all of them have weak signal.
So I turned ON the phone and WiFi and it didn't find nor any single network,I turned off wifi on again nothing.
Here is the picture of that issue.
I also can not find what model of wifi card is in my phone,to check if it was replaced,so I'm suspicious about that.
Btw I don't have any wifi issues when I am on local coffee shops/bars nor at home.
Just at places where like wifi signal is weak and like there are many networks at that place.
So what is this issue about.
I just went to my balcony and simply this phone doesn't detect as many networks as some chinese phone,N10+ detected just 8 and chinese phone 13.
Then all of the sudden phone goes crazy in like 5-10 min and detects like 12 network.
And though signal strength is nearly the same between phones,I'm getting even 10 % lost in download when I do speed test and compare 2 phones.

			
				
so third video,compared to my tablet and s7 edge.
and I will post pics.
Correct me if I am wrong but on tablet and on the phone on the right yeah I see more network recognized but those have weak signal...
N10+ obviously doesn't list those networks for some reason (with weak/no signal).

As you do clearly see on picture N10+ is screwed up recognizing only one wifi network,and my Ulefone Power 5S many...so what is happening I dunno.
Even S7 edge beats it.
I had the same experience on my black note 10+ (4G black model), it would drop the wifi quite often during video playback while my Mate 30 Pro would just continue on the same network. That improved after I reset the network settings and cleared the system cache. I had/have a far more stable connection after that. As for the speed, the Mate 30 Pro would always achieve higher speeds than the note 10 +, no matter how many times I did the tests on both devices. As for the amount of networks it shows, my current note 10+ ( a 4G model but a white one) does only display 1 network at home while the Mate 30 Pro shows 5 or 6 different networks but all of them with a very weak signal strength. Besides them all being password protected I doubt if the Huawei would be able to connect with any of these so whats the point of showing all these weak networks. Maybe that's the reason the note 10 does not show them? Maybe the are filtered?
Both the black and the white are showing similar behavior, I have them both side by side and both are showing the same (single) network being available.
No problem with wifi with my Note 10+ N975F/DS, Good and stable connections.
I do confirm that in the wifi settings only stronger networks are displayed. When using app like WiFi Analyser I can see that there are more networks detected on the Note 10+ than shown in the wifi settings.
I do observe that wifi speeds on Note 10+ are lower than those provided by my Note 8, comparing/measuring side by side on same wifi network.
But in daily use the Note 10+ has sufficient wifi stability and -speed for my normal use, (matching the speed of my Internet connection of 100Mb) including streaming of HD-Video. I do not play online videogames.
Yep for some reason my Note 10+ doesn't show networks with bad wifi signal,dunno if it's just my model or you experience the same.
But for phone such expensive this is unforgivable.
Look here guys,it does recognize wifi networks with wifi analyzer but doesn't filtrate them so I can connect to them,same happens with my S5e tablet.
That's what I already stated...
You can however connect to wifi-networks detected in WiFi Analyzer (WA) by installing a plug-in (just click on the network in WA, it will prompt you what to install..)

Question A52S signal strenght?

I'm seriously considering replacing my moto G8 power with the A52s 5g.
I sometimes work in areas with low signal strength so I want a phone with decent antenna. Samsung traditional did pretty well in this area but I have seen some reports about poor signal with the A52 (none s version).
Most reviews claim that a52 and a52s is identical except for the updated soc. But a52s have lower sar values indicating better antenna.
So I would basically like to know how people experience the signal strength with the A52s?
I know user experience isn't scientific but I think experience compared to other phones could provide usable information, so any info would be highly appreciated...
It's not very good for me, not better than my old S4 and both haven't great signal strength (at my locations). Sometimes I haven't any signal in buildings that are high and have glass walls.

Thank you for replying. So your experience signal strength about equal to S4?

Yes, I would say it. But I can only promise this for my location and provider.

Hello, I got an A52s 5G, also come from an S4 I9505 and I'm amazed by this very fluid A52s, the signal capture is excellent, even in extreme conditions it keeps the signal stable, but it all depends on the operator and location, I'm in Portugal the coverage of operators here is good.
In the rest, the A52s doesn't disappoint for the range where it is inserted, very good screen, automony even in extreme use lasts more than a day, the gps is quick to detect, wifi, bluetooth, it works perfectly, in normal calls, video calls , social networks, and numerous other applications that I use so far 5 stars, the cameras are very good for those who are not very picky they draw pretty good spells, video is not something I use regularly, but it is within acceptable limits for this model, better just going to other more expensive ranges.
in the end it turns out to be an excellent phone for the price it costs in the mid-range.

That is nice to hear. It seems Portugal use same LTE frequencies as my country so antenna efficiency should be identical.
Thank you.
I have been using my a52s for 2 weeks and find the antenna quality average -just about equal to my previous phone a moto g8 power.
But the moto g8 had problems reconnecting when I moved from an area without signal back to a location with fine signal, requiring toggling airplane mode to regain a signal.
The A52s doesn't have this problem. So that is good.

Is it worth to buy this phone? It would be my first premium phone. Right now using 5 year old LeEco Le 2
I like it a lot!
It is pretty fast, battery easily last a day with 8 hours screen on time. (I'm a power user -on a normal day I stream tidal hifi and run google maps while driving 3 hours). 120hz screen is very smooth -my first high refresh screen so didn't really know what to expect. Compared to my previous phones from Motorola and Xiaomi everything just seems to work out of the box on this Samsung. And because of the physical similarity with regular A52 accessories like screen protector and cases are very easy to purchase.
Only slightly negative is Samsung's apps -I'm used to google contacts, calendar and calc. Samsungs browser is kind of nice but the other Samsung apps seems pretty redundant to googles stock apps.
I wanted an affordable and snappy phone with dual sim (it serves double purpose as work and private phone), flat screen, 5g and plastic back. For me Snapdragon soc and water/dust protection was also "nice to have" features. So the A52S is pretty perfect for my usage.
That said I got this phone cheap (with a 6 month contract). If I had to pay full retail I probably would have kept using my (painfully slow) moto g8 power. I honestly don't know any cheaper phones that would meet all my demands...
Signal reception is good where I live, Sweden, Europe, for the A52s. I have tested it with some of the major networks and it does well on par with most other current models. I can't really detect any substantial, real-world difference between the newer phones. They all perform the same under the same circumstances.
I have the A52 5G (none s) version.. I'm with T-Mobile, and have absolutely no issues with signal strength.

In my A52s, GPS signal is little weaker than previous J5 2017 and wifi much weaker than J5 2017. And USB OTG don't recognized by phone. (That is check in Samsung Service).

Makes sense considering wave reflections on mirrors and attenuation because of the wall thickness/height.

Question Samsung Galaxy A54 - mysterious issue with LTE signal strength

Hello team,
I have a question regarding the Samsung Galaxy A54 smartphone. I've noticed that the LTE 4G signal is weaker on SIM 2 compared to SIM 1. SIM 1 and SIM 2 have different operators, and it's not surprising that SIM 1, usually having a better network, shows a stronger signal. The problem lies in the fact that I previously had the Samsung Galaxy A52S, and in the same location, it showed a signal strength of -96 dBm and 42 asu, while the A54 shows -106 dBm and 36 asu, one bar less than the A52S. So, it's the same SIM card (which is essentially new, received it about 30 days ago), and I've had the A54 for about 15 days now.
To sum up, the phone is new, the SIM card is new, the phone works perfectly fine (except for the issue with Bluetooth disconnection in the car, which is likely due to the car's 2012 Bluetooth system being only for hands-free calls), there are no damages (it's a new phone, there's nothing to discuss in that regard). I'm just curious about this LTE signal strength issue.
Now, I don't know if there's a possibility that the algorithm displaying LTE signal strength is more accurate on the A54, showing a more precise strength compared to the A52S? Is it possible that there's a firmware bug that could be fixed in the future? Could it be that the A54 has a different manufacturer for the LTE modem compared to the A52S, resulting in different signal strengths and so on? I don't know any of this, so I thought I'd ask here if there's anyone with a deeper understanding of the architecture and hardware of the A54? Official specification lists don't provide this information, and since my phone is new, I would really like to solve this "mystery."
Regarding other differences between these two phones related to this issue:
On the A54, both SIM cards can connect to 5G, while on the A52S, only the SIM card with mobile data enabled could do so.
The A54 uses the Exynos SoC, while the A52S uses the Snapdragon SoC.
Could anyone know what the issue might be?
Thank you very much
