Hi All,
I face a network discontinuity in my GRAND when both the SIMS are active. Calls and messages are not connecting properly sometimes and had to know only when our friends inform us, Facing this same problem in Galaxy GRAND/QUATTRO/S Duos..
What is the use in marketting it as a dual sim mobile when all the dual mobiles facing this problem.
Is there any resolution for this problem?
I am facing the same issue too,may be the latest 4.2 firmware is causing the problem. While using the Data services I am unable to receive calls most of the time.
I had this problem from the initial firmware 4.1.2 as well. Low quality mobiles like mmx, karbonn etc works good with dual sim feature but not samsung
Please check your SIM cards, they may have dirty or worn out connectors. If that is fine, then check your settings. You can set up the phone for dual standby or dial active or data on one SIM and voice on the other etc. Limitless choices that are not available on non branded phones. I have used the Grand in 4 countries now when I travel and across more than half a dozen service providers. Have never faced any connectivity problems on the stock Rom both 4.1 and 4.2

I bought a new sim then too I am facing this problem. I tried sim of another operator, the same problem occurs. I tried setting one sim as GSM only and other as WCDMA only. Then too problem occurs. Actually, the sim which has 3G plan activated has no issues. Problem occurs on the other sim. I have activated dual sim active as well. I have deactivated data on the phone and I am monitoring and seeing no issues till now. But this is not a solution as if you buy a smartphone and cant use it for 3G it is of no use. Please guide me on this issue. This is frustrating me..
Bought g2 on sept 14 from the 5th day it s having network connectivity issue..cant use 2 sim..if only one sim is putted not much pblm..wen goin on 2 sim..network wont connect..irregular network..useless smartphone..no value for money..shame on samsung as other less price mobile phones has no problems at all..i request samsung to take back all grand 2 having these issues..

Are you using dual sim.I faced similar issue while using two sims but after removing one,the network reception of the other is good.4g works just fine
Yes.i am using one sim only....4g is fine.low signal area other phones working good .but a50 poor network reception
So anyone observed a limited wifi 6 download data tested by SpeedTest apk in a near proximity of a wifi 6 router (5GHz band) ? I've made a short comparison between 3 phones and Samsung was the slowest . Much slower !!!
"Device Specifications"and "GsmArena" shows same features for all those 3 phones I tested . What is the motive ?
Regarding this I read some others opinions and it seems it's a general state of facts for A52s .
This phone is limited WIFI6 on > 600Mbps...
This phone knows 160Mhz but it only sees 80Mhz regardless of the situation. It shows you 160 but it works like 80
WIFI 5 max speed 350Mbps....
WIFI6 max speed 500Mbps.
I have Digi Romania with 1Gbps link and ONT Huawei WIFI6 and i use Huawei AX3 PRo .. but same speed ONT/Router...
da , inteleg , am aceleasi echipamente si sunt tot la DIGI dar de ce limitarea asta , nu-i vad sensul ....
poate ca au mai taiat din costuri cu un modem mai ieftin idem cu virtual proximity sensor
Yep , definitely radio modem is cheap , Phy Rate is very low . This is not a software issue rather than hardware so I don't expect any improvements in the future updates

I also notice problem with WI-FI and Mobile antenna.
Every single Wi-Fi router and Wi-Fi network I've pared shows me 65 mbps.
Almost 99% of the places where Xiaomi Mi 11 have 5G, A52s connect only to 4G+.
There is also huge gap of upload speed when both phones are on 4G Plus. The Xiaomi upload speed is over 50mbps and A52s is 10 to 15.
I tried everything from reset to operator settings without any success.
Yes , due to specific of the thread I use for daily connecting people an OnePlus Nord 2 . There is a huge difference between those two regarding connectivity . OnePlus is also a mid-range phone but compare with Samsung A52s is at least one class over . Snapdragon 778G+ 5G has implemented FastConnect 6700 a connectivity chip which it's said " The Qualcomm® FastConnect™ 6700 system is an advanced 14nm 2x2 Mobile Connectivity system that is designed to accelerate premium Wi-Fi connectivity for mainstream smartphone and computing devices. By extending the power of Wi-Fi 6 into the 6 GHz band (Wi-Fi 6E), the FastConnect 6700 supports Wi-Fi speeds approaching 3 Gbps, ultra-low latency and multi-user feature innovation delivered to new and clean 6GHz spectrum." Also " Wi-Fi :
Peak Speed: Up to 2.9 Gbps , Standards: 802.11ax, Wi-Fi 6E, Wi-Fi 6, 802.11ac Wave 2, 802.11a/b/g, 802.11n , Wi-Fi Spectral Bands: 2.4 GHz, 5 GHz, 6 GHz , Peak QAM: 4K QAM , Wi-Fi Features: 160MHz channel support, MU-MIMO, MU-MIMO (Uplink and Downlink)" So maybe lack of WiFi connectivity it's just a software optimization issue .

Yup, same carrier, different sim card. But sim is tested, it's not the problem.

I think its because Xiaomi has CA for Uplink but A52s hasn't, for example Mi 11 Lite 5G NE with same Snapdragon X53 has CA UL but A52s hasn't.
A52s is very capable device and it's shame that is so software limited.
You're all missing the crucial point. There's nothing wrong with SOC nor software. Galaxy A range only has one antenna so it can't use 2x2 MIMO like Galaxy S range or your laptops.
That simple

Hmm ??? "Samsung Galaxy A52s 5G has a Qualcomm X53 modem onboard , supports dual-mode 5G with 2x2 MIMO on mmWAVE and 4x4 MIMO on sub-6GHz "
Same modem as Motorola Edge 20 , Realme GT Master 5G and Xiaomi Mi 11 Lite 5G
Yes, the modem supports it but Samsung only used one antenna as cost-cutting measure
i found WCNSS_qcom_cfg that wifi bonding and a few other features were disabled in it, with root access we can modify that file and limitation should be ommited.

Exactly, it's SISO, which is such a shame. (source:Samsung website)
And compared to my late Pixel 3a (2x2 MIMO), it's extremely obvious. Even time it takes to search for wifi and time to connect to network seems to me like 2x-5x (in extreme cases) slower...
