Mobile Signal/Antenna Issues: Samsung Galaxy Note 10+ 4G

[13120919195]

Issue: Receiving basic network signals. Calls/text + 4G
Length of Time: Noticeable since April 2020
Phone: #Samsung Galaxy Note 10+ 4G (SM-N975/DS)

Hello,

I'm having sporadic signal reception, to the point of the phone being almost unusable. I've used Sky Mobile and now using Virgin Mobile, both which piggyback off the O2 network.

Signal status of the TW12 area states reception is available and service good. Last year there were issues with network masts that required months before they were repaired and believed that to be the cause of the issue, as my Note 10+ 4G was receiving decent signal.

I've read some model's of this phone that they were released with faulty antenna's, or their ability to receive signal reduced in order to preserve the battery from overheating. 

Things I've tried to rectify/observe:

1. Hard resetting phone to factory settings.
2. Walking various different route both in Urban and rural areas.
3. Observing friend's phones signal reception (Samsung/Oppo) with various networks (O2/Three) which more often than note have signal/data, or can at least make a call/text.
4. Contacted Samsung support chat, but suggested to reset phone and see how it goes. 
5. Reset my Sim toolkit settings.
6. Manually selected network rather than automatically.
7. Turned off roaming mode.
8. Turned off wifi call settings.

At times I may have 3 bars of signal reception, but a message will display on the top screen "Unable to find a network"/"Emergency calls only", or 4G symbol is displayed but can not get internet.

Update

Have purchased the 22 Ultra model with exchange program directly from Samsung. No device issues so far, happy with purchase. However I would of been more than contempt with my Note 10+ if it didnt have the unfixable antenna issues.

I have the same issue in Note 10 plus, very disappointed.

Any help ?

Looks like a motherboard fail, there is no way to fix it without changing it

Good luck with that, the s22 ultra suffers just as badly. I have a note 10 plus and it is much better so much so that I'm selling my s22 ultra. Samsung in my country can't even bother to get back to me about returning the phone

I have the same issue on Note10+, Any clues ?

OHEEEMMMGEEE I have the same issue! Came here in hopes to find a solution & now I'm even more disappointed. I love this phone other than the obvious, obviously. When I'm at home I get no signal whatsoever! I have to rely on wifi & a darn textnow #, which I hate having to use. Ugh!

I have been experiencing the very same issue.

Here it goes:

- 2g works

- 3g 4g and sms won't work or work intermittently as soon as i select "auto" in mobile network selection (it then goes into 2g/3g/4g auto-select mode

- if people call me they get a msg that my phone is unreachable , it does not even forward the caller into voicemail

- i have tried, reset phone, rest network, new sim, all kind of settings combinations.

- only solution: select 2g ONLY in Network Mode and then my phone is reachable ans i can get sms twxt messages
