Signal Issues! 4G, 1 Bar, no calls, texts or internet?

[Anonymous]

I'm having an issue with my phone and found some interesting stuff which i would like to know if anyone else has the same problems. I have raised this with o2 but fobbed off many times so hopefully a group of people reporting it might give them a kick.

I have a Sony Z3 and it keeps locking onto 4G despite there being no 4G in my area and no plans for it this year. I have found that a bug in the Sony firmware has left thousands of Z3 phones locking onto poor 4G signal rather than using the much stronger and fast 3G signal.

I have recent found that Blackberry 8520 phone are now having issues in my area with the internet. 8520's are non-3G phones and use the old frequencies (GSM) to receive internet services. It has been suggested that a o2 are testing the old frequencies, preping them for 4G and at the same time broadcasting this which then causes issues for Sony Z3 handsets.

I have reported this to o2 multiple times but they feel its not there problem as its a bug in the Sony firmware. I feel it is partly there problem as the sell Sony Z3's as compatible devices for there services.

Has anyone else had these issues? would love to hear about them and hopefully make o2 listen.

Could be that it's not optimised for the O2 network.....?
But the O2 apn should help rather than a generic one?

I have thought that before, I'm sure O2 optimise it, I started a thread a while back when I was on the UK generic.

The solution for me was to flash O2_UK firmware.

But obviously that's not a solution for everyone.

My recommendation is to spend a while on XDA forum for Z3 and learn how to flash a ROM while unticking wipe user data.

This is an interesting one... I've seen problems like this before on earlier Sony handsets, and Viridis is correct the O2 firmware does "appear" to provide a better signal strength, however each phone vendor and subsequent service provider can change the levels of signal displayed, what is 5 bars on one manufacturer is 3 on another, this is only how the firmware provider decides to display signal strength.

I've got a Samsung Galaxy Note 4 and since the beginning of April I'm having this same exact issue, 4G is also not available in my area but I'm getting it on both my N4 and iPad Air 2.

Network Services believe I shouldn't be receiving 4G and they're looking into it, this has caused me some serious issues because I've recently gone self employed and I'm working from home now and I'm missing alot of calls now as they tend to go straight to Voicemail or the other person gets unavailable tone. I full well know that o2 cannot provide me a coverage everywhere but going from a poor signal for 12 months to a now non existent one is very frustrating! The TuGo app doesn't solve my issue but enhances my poor signal due to it not kicking in when it should.

I'm currently liaising with the Executive Office about this so I'm hoping they can resolve my issue or at least we can come to a satisfactory resolution.

Change network mode to 2g or 3g.

If you are in a fringe area or work is ongoing it could be issues you are getting. Follow the advice above and if you are pay monthly then TuGo may help when connected to wifi.

Hi both, I've already tried 2G only mode and 2G/3G only which doesn't make much difference.

TuGo unfortunately is too unreliable, it's ok for outgoing calls but incoming calls do not work!

Network services have advised that this issue can take several months before it can settle down, even then he couldn't guarantee it would.

Any chance you can keep me updated with the outcome? also, how did you get in touch with the exec office? I constantly get fobed off and told my phone is broke and they dont have an offical complaints procedure apparently.

On another note, further to this thread I now have another work phone with the same issue. This phone is a Blackberry Q5 which is switching to 4G and at this point they can't make phone calls, text or internet.

To summarise, thats 2 Blackberry 8520 thats no longer get 2G, a Blackberry Q5 that gets 4G, a Sony Z3 that gets 4G, no 4G towers in the area and 2G and 3G are fully fuctional with no faults yet o2 maintain that my phone is faulty.

please!
