Can anyone compare GSM radio performance on the Rose to the Raphael (Touch Pro), or diamond?
I am having real trouble with poor GSM signal on my Touch Pro, and am considering switching to Rose - if it is better. I think Rose shares a lot of the hardware with the Touch Pro/Diamond, so I suspect radio performance will be similar.
TIA

RF always depends alot on where your at. I have both the S740 and the pro and find both have outstanding RF. I have no issues with either. I'm in Arizona and use t-mobile. T-mobile is big on coverage in AZ tho. I never have probs. with any of my devices here. I think you will see no better RF perf. with one over the other.

Oh well. Unfortunately, where I live and work, network coverage is pretty poor. And in this situation I know that my S710 (vox) totally outshines my touchpro for reception. I was hoping the S740 radio performance would be more like the S710 than the touch pro.
By the way, I am on GSM 900, and I guess you will be GSM 1900, so you are likely to have more densely arranged cells - the nearest base station to my house is over 1.5 miles with a large hill in between. The fact that I get any signal at all is quite impressive I suppose.
I had a S710 before - my new Rose has even a better reception (Germany, T-Mobile) ...
Have to admit, from going from a Tytn II to the S740 my signal quality has dropped by at least a half for indoor coverage (from full on the Tytn to 2 on the S740) but no difference in outdoor quality.

I have a Treo 750 which is my primary phone and use ATT as my carrier. After adding a data plan to my service ATT offered me a free BlackJack. Who am I to say no to free toys. Anyway I have been running an A/B comparison of the two phones and find the BlackJack radio appears to have a far superior radio to that of the phone. This is based solely on the value of the graphical receiver signal. I work for a marine electronics company and use several pieces of test equipment to generate a minimum discernable signal level for checking receiver sensitivity but do not have anything that would work up in the cellular range.
Has anyone else made any comparisons between the Treo and other phones? If so what have the results been?
Is the Treo any better or worse than the rest?
Are there any mods or radio improvements for the Treo?
I noticed the reception of the evo 3d is not that good. I can barely ride my bicycle with internet radio playing. Also bluetooth range is less then my motorola droid when connecting to the same devices. Did HTC make a good phone with poor reception capability, or is it sprint that has bad coverage?
I am considering trying a Nexus S since I'm still within the first 30 days of service. Does that phone have better reception?
Thank for your feedback
I would ask in the Nexus S forums...
My EVO 3D gets very poor signal and reception. Much worse than my regular EVO 4G. I noticed this right away as soon as I activated it and wasnt able to get as good of signal in good coverage areas like I could with previous EVO 4G. Its a combination of poor radio performance as well as poor Sprint service. The EVO 3D is definetely not a good "phone" and that's the most important thing to me.
I had to get rid of my Samsung Galaxy S due to poor reception. I then switched to the Optimus P500 and it was great for reception. I recently got the EVO3D and have had no complaints so far on Rogers in Canada, even in the remote Milton areas where it was questionable with the Galaxy.
I used to have original EVO and went to Epic Touch (Sammy SGII) and was really disappointed with the Samsung signal quality compared to EVO. Especially when in a weak signal, EVO 3G data would work fine but SGII sometimes would not work at all if signal is weak in same spot.
Have tested it many times. EVO was OK with 3G data if barely a signal, SGII would be hit and miss in same spot.
For those who switched from Epic Touch, how does new EVO perform with weak 3G signal? I'd think with the Qualcomm chipset, EVO should do much better than ET/SGII.
Samsungs are notorious for horrible radios.
They can suffer from something called LOS. Loss of Service. Where you basically lose all connection altogether until you reboot.
In fact my sisters galaxy s2 isn't even 3 months old and its been to samsung twice.
and is currently sitting with them waiting on backordered parts.
You won't (well probably won't) experience that issue with any other device maker.
As far as i know it exists on all the current samsungs though, gs2 and nexus alike. probably the gs3 as well.

Considering Qualcomm invented EVDO (Sprint's 3G) and the chipset with integrated EVDO modem, it would surprise me if the signal is weaker.
That said, the device is thinner -- flimsier antenna?
Some reviewers, however, are quick to point out that 3G strength is increased compared to the 3D, if that means anything to you:
I've already mentioned that connectivity on the EVO 4G LTE is awesome in general; it usually picks up a stronger signal than my EVO 3D on both the cellular network or any surrounding WiFi networks. Additionally, mobile data speeds are consistently 300-500kbps faster on the EVO 4G LTE than on the EVO 3D, even when the devices are side-by-side.

Signal should not be as good as the EVO 3D...S4GRU article on the FCC doc released for the device explained it...its not a big difference nor something you will notice much i think, but its there according to the FCC testing done...
The N2, S3 and S4 are very good data devices when the signal is medium to good, but hot running battery sucking demons with weak signal. Part of the issue is the radio technology itself, but the other is the actual radio chip used and how it manages weak signal. I read where the S800 works better with the radio chip and low signal, but also read this is in regards to the newer LTE signal and not current tech used in the US.
I appreciate a lot of folks will be blinded for a few days by new device pixie dust, but any perceptions yet?
Mine are almost similar S3 and N3, LTE its usually always around 86 dbm for me
I am getting way better speeds on my N3 vs. my S3 running MIUI. Was getting -113 on the S3 with dl speed under 1Mbps. Now getting -93 with 5Mbps. My cubicle is the black hole of 4g so I'm very happy now.

I changed telco recently, to SFR (in France) and am getting very poor 4G reception at home. I haven't used the data connection at home before (because I have WiFi) so I didn't know what to expect.
The mast is only 2.8km away and LTE800, so the OPX should like it. The SIM card works well in my partner's Xiaomi, and in my old cheap and cheerful Alcatel POP4, and both get a strong and stable 4G signal. So why is my OPX struggling? I've been on to the support at SFR and they are going to monitor the line but said everything looks ok (APN details good, no local outages, etc) so it should work.
The only strange thing that might help in problem diagnosis is that I had to create the APN myself. The correct one was not displayed on the OPX - several other telco APNs were displayed (around 15 in total) but not the one I wanted, which I find weird. In the other 2 phones (Xiaomi & POP4), the correct 2 APNs are the only ones displayed.
Do you think there's something wrong with my OPX? Is it simply 'weaker' than the other 2 phones I have? Might it have a problem with that particular mast? (I get good 4G elsewhere) This one baffles me.
Nobody any thoughts on this?
It was suggested to me that perhaps the OPX designers compromised 4G reception (due to limited physical space) and upper band LTE is advantaged over LTE800. because the majority of 4G provision is in that upper band.
I have noticed this too!
Consider I live in a little country where 4G signal is low.
The same happens in Rome where 4G signal is high!
In fact, with Mi A2 lite I have no problems.
Probably the hardware is not very well designed, like you said above.
I don't like to resort to unhelpful, nontechnical language so consider this as venting - 4G reception sucks on the OnePlusX!
I'm seriously considering getting another phone (and I otherwise like my OPX) because its 4G reception is so weak. Sure, it works on occasions but I know other phones do better. Still, I guess it is now 'old' technology!
It looks allright with my OPX in France too, with Prixtel (Orange).
I have my main Sim card with Red SFR in my main phone, but with the OPX, the 4G DL and UP speed are good.
With Prixtell, I get this right now:
Hello,
I have a same problem with Bouygues, I have a better connection with sosh/orange...
the Bouygues/SFR antenna is at 3km
orange/Free is at 1Km
and traveling by car the reception is less cut with orange / sosh
I've come to the conclusion that it's the OPX hardware and/or design. Nothing we can do about it... other than get a different phone!
Fortunately for me, it's not a real problem - i's just a limitation, a bit frustrating and somewhat baffling. As I said, my cheap and ordinary Alacatel phone has a better 4G reception!
Are you by any chance using dual sim cards? I've noticed that my 4G reception is also worse ever since I started using 2 cards.
Also, reception appeared to be better on stock Oxygen OS than it is on LOS15.1 that I'm using right now.
