Problem with my Nexus One

3G and H are both different types of 3G. Some ROM will distinguish between them, other ROMs show them both as 3G. H is faster than standard 3G, so you don't have a problem...
Edit: OK, that's weird. My response appears before your question, and the time is wrong...?

Hi,
I recently brought my Nexus One for repairs because my phone would restart automatically after my phone gets to hot. After I got my phone back from repairs, they must have fixed the problem. But then another problem started! I have problems with my Nexus One to connect to the 3G network in my area.
My Nexus One sees the network. But when I try to use 3G it looks like it tries to connect to it but the network doesn't seem to respond. Then sometimes my phone switches from a "3G" to an "H" and that works always.
Does anybody know what the problem might be? I can't barely send text messages, place calls or use the Internet! I hardly think that its a problem with my network provider considering that my brothers G1 phone works wihtout any problem!

Maybe the idiots at Telamon sent you the wrong model? (T-Mobile vs. AT&T?)

If that was the case, he wouldn't be seeing H. If he's connecting on H, then he's all good...

Check that you're using correct APN for your carrier.

My phone doesn't always switch to the H. Sometimes it sits at 3G and it seems that the network doesn't respond. Sometimes when I use WIFI it takes a few minutes until the WIFI starts working, even though the phone indicated that it connected to WIFI correctly. I was using the standard Android 2.2 ROM from Google but I decided to put on CyanogenMOD a few weeks ago but its still the same problem. I guess I'll just have to deal with it...

[Q] Force 2G mode when on home wifi

Hi,
I have patchy 3g but a good 2g signal when at home. The problem I have is my Z1 keeps flipping between the bad 3g and the good 2g.
When I'm at home I would like it to be forced to use the good 2g signal only so I would like it if the phone worked from 2g only when it recognises my home wifi.
My original thought was tasker but when I tried it, the radio section is not available, saying not compatible with this device.
Anyone know what else I could use ?
Thanks,
malty

When connected to wifi, doesn't the phone just turn off all mobile data? Mine doesn't show 2g or 3g or any indication of any mobile data being active when on wifi. Unless I'm missing something?

It's not data that's the problem. for calls and texts it is still connected to either a 2g or 3g mast. I need it to be looking for and connecting to a 2g mast only, since the 3g mast where I live is poor signal and is intermittent but since the phone would prefer a 3g over a 2g signal, it tries to connect to it anyway.
As stated I would like it to be in GSM (2G) only mode when I'm at home and automatically switch to 3g(preferred) and 2g when away from home.

Hi,
I know this isn't exactly what you're looking for but you could try installing this ROM.
http://forum.xda-developers.com/showthread.php?t=2463675
It's listed to have a force 2g option and you might be able to find a way to automatically trigger it.
I also found a Radio Switcher app in the Play Store, but again, not perfect.
Hope this helps.

As far as I know, you can't have automated 3g to 2g switching even with a rooted device because android prohibits it.

tasker will do it but the radio section in tasker is greyed out with the explanation 'not available for this device'

From what I've read changing network settings is protected by Android, and thus not possible if running a rooted stock-rom.
If someone comes up with an idea how to rescan/update the settings without a reboot that works (http://forum.xda-developers.com/showthread.php?t=2230207), please tell as I also have horribly bad coverage of >3G at home.

[DISCUSS]All Nexus 5 3G issues here

Hello Guys. Nexus 5 has been here for a long time now but we are still eagerly waiting for some issues to be fixed by Google.
One of the major issues that people are facing is getting the phone in 3g mode.
Some users just can't select 3g in preferred network i.e. if they select 3g in preferred networks and press back button and again go to Mobile Networks menu, the preferred network would go back to 2g or LTE automatically.(I am not having such issue but my issue is mentioned below)
The bug I am facing on my Nexus 5 is that my phone can select the 3g preferred network and the settings do stick unlike the issue mentioned above but I get no service when the preferred network is 3g. There is no LTE in my country but 2g works fantastic! I tried my sim in my brother's Xperia P and he received full 4 bars in 3g mode! I tried his 3g enabled sim in my Nexus 5 and again no network when in 3g mode. This clearly shows that Nexus 5 is having something wrong. I don't know if this is hardware related or software but I want to get this thing fixed as soon as possible. I have even tried flashing stock firmware and selecting WCDMA only in the *#*#4636#*#* menu. Any suggestions?
Also, if anyone else is facing any 3g related problem, he/she may post here so that other users can help out! Peace :highfive:

Almost the same. I could select 3g. It waits a bit or more to show up.
From time to time, I could barely use the internet.
I have no other phone to compare.
Best regards.

What gets me is low signal areas. It says "use a valid sim", when there is one. It goes to no bars and says "reboot". My Nexus 4 would just go down then up when the signal improved. Basically I have to reboot all the time. When im @ mine is great but I've 5 bars

on 3G: I get late notifications specially on whatsapp, they are like 10-15 mins late it's kinda irritating but I get instant notifications on 2G network.

So 4.4.2_r1? I think we can assume he's using the latest version of Android as well.

Hi, I am also facing the same problem, no 3g, it seems this problem got started after I recently updated to Android 4.4.4_R2 KitKat (KTU84Q), so I rolled it back to previous version, still the problem persists, not sure what to do next, would appreciate any help
thanks

In my experience it's down to network. On Vodafone I had loads of issues with 3G refusing to connect whereas with 3UK I've not had a problem

Mi5 lte issue with all roms

Hello Fellow MI5 Users,
I am writing this thread to see if anyone else is having issues like me with my Mi5.
The problem is the intermittent signal issue with LTE, My problem started when I flashed 6.7.28 miui 8 update at first I thought that it was my Network Provider, but when I checked my dad's and sisters phones (same provider) their 4G signal is very stable without any issues at all.
So to describe my problem this is what's happening to my phone.
My phone is now running the latest Global beta miui8 6.8.12
When switching to LTE as prefer connection my phone signal goes crazy from NO SIGNAL - NO SERVICE - EMERGENCY ONLY - NO SIMCARD as I dig in to my settings i change my preferred connection to 3G Only which in my surprise works well and perfect without any issues but the problem here in my country(Philippines) you cannot rely on H or H+ at all since the network provider service sucks bigtime!
So far here's a list of what I did with my phone to fix it
- Flash back to China miui8 later version that I remembered that I don't have any issues with my LTE(Sucks because the issue was there also when I went back)
- Flash to MIUI 7 (Ohh well at this point I thought going back to miui7 will fix this issue but NO, not at all and I'm losing patience)
- Flash all KINDS of CM Based OS (Well switching OS might solve the issue, But believe me it got worst! after flashing all kinds of CM Based OS on my MI5 it all went down to Reboot forever bug (this happens when my phone boots and phone started to connect to LTE)
- Went back to Global beta miui 8 6.8.12 basedband version TH20c1.9-00038 up until now im still using this version.

Could it be you're own carrier hasn't got coveridge for LTE for your device?

In my country lte is Band 3(1800) and mi5 should support that band,right?

For me my carrier do support coverage for MI5, but just recently it went nuts

hi im using official global rom with my mi5 but i cant make native video call on my gsm operotor because of not support miui 7 and 8 so.. is there a rom support native video calling like samsung ?

Mi5 Prime user here. same problem with LTE as well using GLOBE sim, no problem with SMART so far. using China ROM MIUI 8
here are my observations
GLOBE switched to LTE - stable when stationary.. goes NO SIGNAL / EMERGENCY CALLS ONLY when moving in a vehicle
i guess there is a problem on the radio signal switching from H+ to LTE vise versa. unlike my other phone - Meizu M2 Note. no problem switching between 3G / H+ / 4G.

Sucks right? I wanted to switch carrier as well but then again, LTE coverage with smart sucks specially in my location... Hoping that this will be fix soon..
I used to have a perfect LTE with globe 4G+ after some time after updating OS version it went nuts

I updated my mi5 to miui 8 global and got 4g signal but only for a minute or less then it dissapeared and when i manually choose mobile networks i can only select Telenor 2g and 3g...really weird.

Hello James,
I am having the exact same issue on my Globe Sim. I just bought mine last week. Whenever i turn on my mobile data, signal suddenly goes to no service, not detected, etc. Its very frustruating.
Is my unit defective? Or is it just a firmware issue?

I am using both Mi5 and Redmi Note 4x. In both phones, I experience frequent network connection drops for both SIM cards in serted on the phone (one is Sun, the other is Globe). Even while stationary, I exeperience the network drop where the signal bar for both SIMs suddenly simultaneously disappear. The network drop is worse when I am mobile. In addition, the network drop is causing the app I am using at the time to restart. PLEASE HELP.

hi.. is this thread still active? have you found the solution?
i am also from the Philippines, been using globe for 2 years in mi5 with no connection problems, then recently, when i try to connect to data, the signal goes on and off just like yours.. just this month, i updated from miui7 to miui9 and the problem got worst! when i connect to mobile data, phone reboots after a minute! i tried every fix i found in the internet (reset APN settings, factory reset, airplane mode) but nothing seems working.. So i tried Sun as my other network and it works perfectly fine.. Also, i tried to interchange sim 1 and 2 slot but still not fixed.. Another thing, when i turn the data in different place, my connection seems okay.. i live in cebu city but works in lapulapu.. the problem occurs in lapulapu..
help! is this network related or somethings wrong with the phone?

Good to see this thread. I thought my phone had a factory defect.
based on my experience.
version 9.1.1.0 and below only loses signal for globe while on data connection in some locations .
higher versions up to the latest(now is 9.5.5.0) causes our phone to totally reboot in some locations as well.
maybe it has to do with the signal/radio frequency on the area for the identified carrier(Globe).

this is easy.

Data connection drops

Im from the Philippines and im using a Globe prepaid sim LTE ready. My mi A2's cellular connection always drops. When i tried my sim on other devices it works just fine. Haven't been able to play online games because of the connection drops. Wifi is good tho. i tried to play with the *#*#4636#*#* the different modes but still no luck.

When you tried other devices it was in the same place ?
Did you try an other sim with a different operator ?

Hi guys, I am facing this problem too, mobile data is always with the cross and only work when the signal is totally full. I already reset the connection settings but the problem persists. In wifi i get drops too, and sometimes i just can connect again by restarting the phone
