Guest saquib Posted January 8, 2010 Report Posted January 8, 2010 Moving from a Acer Liquid to a Nexus. One of the most impressive things about the Acer was excellent radio signal including 3g speeds, compared to HTC phones I've owned over the last 5 odd years. Already we've got reports of 3G issues, mainly US users. I'd be interested to see what the experience of UK users is. Mine is stuck on Awaiting Ship so can't comment! 3g Issues ?

So far only had it running for a day, however its been great, signal was better than my G1, by 1-2 bars. Will have to see over a little more time i think.

Will have to see over a little more time i think. HTC phones have notoroiously bad signal levels compared to other phones. I'd be realllly interested if anyone can do a side by side comparison with a nokia, SE, another HTC etc on the same network. I know they may be on different cells but at least we can get an idea.
Guest Asim Aziz Posted January 8, 2010 Report Posted January 8, 2010 signal is actually better than my acer liquid ( im on vadafone) holds on to 3g much longer before switching to 2g but still no contest with the old nokias imo

No issues with my Pulse, Same position in my office, same SIM, same settings. Reports 3g but when I try to use it drops back to gprs. Oh dear. This might need to go back.

Guest martinbrook Posted January 8, 2010 Report Posted January 8, 2010 Hmm thats worrying. What signal level on 3g are you showing or both phones? I have two pulses and the nexus. I have two t-mobile sims and 2 o2 sims. Just getting the nexus charged up then I'll start the combination testing. Should be able to work out where the problem is and get some photos to prove it. Getting it fixed though thats going to be the problem with HTC pointing you to the network provider and the network provider passing you to HTC. Google just sit in the middle with a smile I guess.

Guest Robert Davidson Posted January 8, 2010 Report Posted January 8, 2010 I have noticed that I am only getting a 3G signal with 2-3 bars when I was getting H (HSPDA) on my Hero on Vodafone (UK)

Martin Here we go then. I have nexus on o2 and pulse on tmobile. I have nexus on virgin (tmobile really same cell id) and pulse on tmobile as before. Now nexus on virgin (tmobile really same cell id) and centre pulse on O2 which was in nexus in pic 1 and pulse right on tmobile as before Now the pulse seems to be pulling in a better 3g signal on 02 than the nexus. But the nexus is pulling a better signal from the tmobile cell so I don't think the antenna is bad in the nexus. Could this be due to the UTMS/HSDPA difference? What do you guys think I'm not a GSM hack. Martin Edited January 8, 2010 by martinbrook
Guest Ntt4 Posted January 9, 2010 Report Posted January 9, 2010 On my G1 I only ever got a 3G logo. I've never seen a H before :)
Guest martinbrook Posted January 9, 2010 Report Posted January 9, 2010 (edited) Thinking about the I think its the logic of the radio module. See screenshots below is if HSDPA signal OK use HSDPA else if EDGE signal OK use EDGE else if GPRS signal OK use GPRS endif should be if HSDPA signal OK use HSDPA else if UMTS signal OK use UMTS else if EDGE signal OK use EDGE else if GPRS signal OK use GPRS endif Here we go then.

Guest nissel Posted January 9, 2010 Report Posted January 9, 2010 Vanilla android (such as on the N1) does not have an 'H' symbol, it will always display 3G on HSPDA and/or UMTS. The H symbol was added by HTC with Sense UI.

The H symbol was added by HTC with Sense UI. I'm not sure that this is true, I have a Milestone and a Nexus One and the Milestone certainly displayed the H symbol where as I've not seen it on the Nexus yet. Anyone figured out why this is officially?

Not sure if this helps anyone, but I talked with HTC over the phone today and recorded it (crappy built in mic on my laptop, but it worked out alright) there is a OTA update coming out to fix this (known) issue listen to it here http://wootroot.com/blog/?p=1377 (sorry if posting that link violates any rules, im getting very crappy 3g speeds, oh and the info she gave me about locking it into 3g, didnt work for me, ill let update if i get any further contact info) Edited January 10, 2010 by WootRoot

Oddly, i also found that the screen oriantation effected the level of signal, quite drastically. Im unsure if this is just a network 'blackspot' of where I am. Holding it in portrait gave me 2bars, 3g. In landscape 4bars. odd! Download speeds are capped to about 500k down, where as on the G1 i average around 1800k. I have had 1800k on the N1 after it was booted up, however I havent been able to replicate this. Looking forward to the OTA to resolve this bug!

Guest martinbrook Posted January 10, 2010 Report Posted January 10, 2010 http://forums.ocworkbench.com/showthread.p...7237#post457237 Been out and about today and 3g HSDPA performance is awesome when you have a good signal. This problem seems to be when you don't have a good signal. My phone suffers the same issue as in the video when the signal is marginal, ie the phone drops down to Edge or GPRS when I pick it up. It does not seem to try a basic UTMS connection. Martin

Guest martinbrook Posted January 10, 2010 Report Posted January 10, 2010 Have you seen the H symbol yet? How can you tell if you're on 3G or HSDPA? google for any cut and phone info or type *#*#4636#*#* in the testing screen that pops up select phone information scroll
Guest martinbrook Posted January 10, 2010 Report Posted January 10, 2010 Just been talking to HTC support. "Hi Martin, I'll add the performance video to my query to the dev team. HSDPA and UMTS are sent over the same signal, just a different software version for the data transfer so if HSDPA signal strength drops, then the UMTS signal has also dropped by the same amount. UMTS only signals are used where networks have not yet updated the masts with HSDPA technology. Best REgards Mike" My reply. Hi Mike, Thanks for the information but, Check out the first and third photos from the original post. http://android.modaco.com/index.php?s=&...t&p=1151594 The nexus on O2 is reporting -109db and is reporting HSDPA connection. But this keeps on dropping to GPRS. Nearby the phone reports -80db and HSDPA and has good connection speeds. The tmobile pulse on O2 is reporting -97db and is reporting a UMTS connection which does not drop and gives good connection speeds. Your explanation about signal strength of UMTS and HSDPA seems to suggest that even if the nexus was to drop to UMTS the signal would still be too weak. If that is the case then can you explain why a 175GBP T-Mobile pulse has a better antenna and radio subsystem than the flagship nexus one. It can support 3G even where a nexus one cannot. Martin
Guest Grousey Posted January 10, 2010 Report Posted January 10, 2010 google for any cut and phone info or type *#*#4636#*#* in the testing screen that pops up select phone information scroll Says UMTS, is that HSDPA then?
Guest Robert Davidson Posted January 10, 2010 Report Posted January 10, 2010 Ran *#*#4636#*#* and it showed that the network is HSPDA, but the phone only shows the 3G icon.
Guest martinbrook Posted January 10, 2010 Report Posted January 10, 2010 Says UMTS, is that HSDPA then? No. it would say HSDPA in the network type field.
Guest martinbrook Posted January 13, 2010 Report Posted January 13, 2010 google for any cut and phone info or type *#*#4636#*#* in the testing screen that pops up select phone information scroll Signal strength is the key as I posted this link http://is.gd/5WUuD on Jan 9th. Same SIM same base station. T Mobile Pulse -89 dBm (cost 175 GBP) Nexus One -109dBm (cost 400 GBP) Go figure.
