Signal problems not Wi-Fi - Samsung Galaxy J3 (2017) Questions & Answers

I am curious if there is a way to enhance my Samsung galaxy j3 emerge signal reception. In town I get good service but I'm out camping and have a poor reception so I am just wondering if there is a way to strengthen the cell phone signal from the tower since no Wi-Fi is around

[Q] Signal Issues

Okay recently my phone has had some really bad signal issues in parts that I always had the best signal. Now it roams and sometimes has no signal at all. I have the Heinz Rom loaded on my phone. One thing is though I live about 40-50 miles away from Joplin where the tornado recently hit. Well in Joplin was the main central hub for U.S. Cellular in southwest Missouri. Is it a chance that the loss of that building in the tornado could have effected the signals around Joplin areas.
Yes it could be that. I had a similar issue in are area when there where floods n high storms the tower cells were damaged and noticed low bars
Well i just got word that the reason why signal is messed up. The joplin US Cellular store was the main hub for the connections of the towers where I live. So when it got hit the towers are only working partially now till they find a fix for it :/

[Q] Boost 4G Phone Signal?

Is there a way to boost your 4G signal? At work, web pages seldom load because my signal drops to a pitifully weak 3G strength.
Is there a way around this?
I have the GS3.
If you're at work then use Wi-Fi ... Or get a cell-tower built inside your office.
It is completely dependent on the coverage of the signal. If you do not have good coverage, there is not much you can do about it.

Call Quality and Signal Reception

I live less than 3 miles from Center city Philadelphia and I get terrible cell reception. My radio goes nuts constantly trying to keep a stable radio signal. It jumps from H to H+ to LTE constantly. I can stand in one place and watch it jump around all day. If I force LTE, LTE just drops out constantly. What is going on?
I have a few friends who all use the same carrier(T-Mobile) with different phones and don't report the same issue. I even have a buddy using a Gnex and he gets better reception than I do. Call quality is not very good either. I was making a call while walking home from class and had the other persons voice drop in and out when the wind started to blow. I dont believe that Wind was effecting my call. That makes no sense, but there was a correlation that went on for 20 minutes.
Anyone else having call quality/ signal strength issues? I am not talking about your data speeds, we have a thread for that. I am talking about tower connectivity and stability .
I don't use my phone for calling, but I'm trying out T-mobile in Janesville and Beloit Wisconsin and I notice that my signal bounces between GPRS, EDGE, 3g and H constantly as well. I have no other phone on T-Mobile to compare to though. Granted all signals have 1-2 bars in most places.

[Q]Signal repeater/booster question/opinion

Hello,
My girlfriend and I are on Koodo network (a Telus MVNO) and we have issue with signal reception in our house. Both phones were getting good signal with others carriers (Rogers and Videotron). According to the coverage map at the Koodo store, we should get strong LTE/HSPA signal in our neighborhood, which is the case, but unfortunately when we are inside our house, the signal drop to -110dBm (0-1 bar) and even no signal at all in some areas of the house. We get descent signal reception right outside our house (around -80dBm 3-4 bars).
What I would like to do is to take that signal from the outside and bring it inside the house so we can use our cell phones at home and get rid of our land line. I need your help to determine which repeater/booster I should use. We don't really care having LTE data inside the house because we already have high-speed internet trough a wifi router, only being able to make/receive calls would be fine.
I'm looking for something priced below 200$-250$. I can do the installation myself without any problem (i.e installing an antenna on the roof if required). I found that one: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=8950334&CatId=4977
not sure if it suited for our needs. Afaik, Koodo use 800/1900 MHz for HSPA and 1700/2100 for LTE
Any suggestions/personal experience/advices would be appreciated. Changing carrier is not an option atm.
Yep,just install a booster,it'll help.

question about cell radio signal

Hi guys recently I bought an unlocked g955u1 from best buy and am on Verizon. I've noticed that my cell signal has been reading a bit off despite doing the Verizon software update. My phone is almost always stuck on 3 bars lte according to lte discovery and the range of dBm will average -100 to as low as -108 which realistically should be 1-2 bars not 3. In the past the only time I've really saw inaccurate readings like this is when I've been on gsm carriers. It's not as much as a problem as more of an annoyance as everything works fine. My question is anybody know why it's reading so inaccurate?
The bars are more or less just approximate visualizations of the network strength anyway. It varies from carrier to carrier, as well as phone manufacturer. You're better off sticking with the dB display if you want a truly accurate reading. Imho.
I have a T-Mobile variant and have noticed the my DL and UL speeds are a lot faster than any of the phone I've had in the past. We live out from town and even on the Nexus 6 it shows 3 bars and on the S8+ I get all the bars and the DL speed on the other phones at my house are around 5Mbps and on the S8+ I get 17-20Mbps at the house now. In town it has gone up from 40Mbps to 55Mbps.
My ATT S8+ reception
While I agree that the dBm is what you should be looking at, I have noticed some funky things going on with my ATT S8+ in terms of reception. Using the same SIM card, placing the phone in the exact same place, my S6 Active has a signal strength of -124 dBm /asu 16/"In service" on LTE. The S8+ gets a signal strength of -113 dBm/asu of 0/"Out of service." To me this seems like the S8+ is actually getting better reception than the 6S Active but the phone is out of service. I also tried this same test in another location using a different cell tower. Same results, the S8+ gets better reception...but the phone does not perform as well. In location number 2 I have also notice the S8+ fish for better signal and switch from LTE to HSPA where the signal strength is -99 dBm but the asu is only 7.
Since I live in a area with weak cell coverage the S8+ is driving me nuts...I contacted ATT about it last night, will see what happens.
Also somewhat related:
I'm using a US Unlocked on T-Mobile, and I've noticed my signal dropping out in areas where I previously had great signal on my Pixel XL. My buddy (also on T-Mo) just got an LG G6 and had full signal when mine dropped out.
Anyone else notice a weak signal? If I flash the T-Mo firmware, will that improve my signal? Did I get a bad unit? I hope not as everything else is perfect, screen included.
i notice (with TMobile) that if i am in 4g lte, then move to area with only edge for a few mins, then back to the 4g lte area...my phone doesn't connect back to the best signal
only a reboot let's me reconnect to 4g lte
