SONY XPERIA Z5 PREMIUM.

berhenne52 — Fri, 15 May 2020 08:07:12 GMT

Hi all,

Would like some advice about an Xperia z5 premium. I bought a Sony Z5 premium about a year ago from China, and i have never been able to make a call with this phone. The area where i live, in the country, doesn't have the best reception, but i have another Xperia phone, which i'm using now, and it works just fine. I am with the Vodafone network. Thing is, when i go to the city, it works just fine. All the reception bars on top appear, and i can make a call, it's only when i get home, down go the bars, and no reception. This is the second Xperia Z5 premium i have bought from China, with this problem. Is there anyway this can be fixed? Why is this happening? Bought a Nokia phone years ago, second hand from China, and never had any problems with reception, so can't figure out why this is the case now! I contacted Sony, and they gave me a few solutions to run through to see if it will fix it, but no joy there. Anyone else ever have this problem? Thanks for your time, cheers.

@berhenne52 Hi,

You can check some search results from the archive about this:

https://community.sony.ro/t5/xperia-archive/cannot-use-3g-hsdpa-network-in-some-conditions/m-p/3387017

Mostly its about the network settings. Can you advise what network settings are you using? Is it 2G, 3G or 4G? It might be also some compatibility issues from the phone with the European network.

Hi Alexdon,

Thanks for your swift reply. To be honest, i don't know. Could be 2G or 3G. When it comes to smart phones, i have no clue about setting or software. Can barely make a call. Lol. I was thinking it may be a compatibility issue myself. If so, can it be sorted? Anything i can try?

To be shure everything is set as it should I would recommend a Software repair with Xperia Companion.

I think that may be a good idea. Thanks for that. I will try it out later. Cheers, Strampke.

Hi Strampke,

I tried the xperia companion, and ran into a software repair error, and couldn't continue to the end, then it said phone has locked up. Just my luck. Help, help. Lol.

@Strampke @berhenne52 yes, backup and repair software as suggested and report to us. Try to use a different network mode though before you do that.

Hi Alexdon,

Couldn't log in the last few days. Something about clearing cookies. 🙄. Sorry, but like i said before, i don't understand all this software crap. All i did, as advised was, i used Sony companion, and couldn't get to the end, and message came up that, the phone had locked up. Cheers.

@berhenne52 and now you can use the device or is it locked?

Hi Alexdon,

No, i still can't make a call. Still no reception. No bars showing at all, as usual. Tried the xperia companion again, and it nearly went right across the screen, but then as always, error popped up. Trying it again, but i know it's a waste of time. It said it was locked, but then could pick an option and i could get into the phone again. This is the second xperia z5 that i bought from this seller, (first one had a cracked screen, and was broken, my fault, but i could never make a call with that phone either, before it was broken).

What I suspect, is that the model and regional configuration for it, differs from the regional spec you need for your network.

Most likely, the band's used in the phone, Vs the band's your network uses. It used to be like this on almost any Chinese imported phone that some networks won't get 4g or 3g, some won't get 4g, or in some cases you couldn't get signal at all as the network you used it on, didn't operate on any of the phones network bands.

This could sometimes be overcome with a software flash, but other times it was just fruitless.

What I would try, is a few pre pay Sims (no need to top up anything) and see if any other networks obtain a good enough signal.

For your network, you can try putting the network options in settings to 2g only and see if it latches to your network then.

Hi LordViridis,

I have bought old Nokia builders phones from China, and never had an issue with picking up my vodafone network. Why would it happen with this Sony z5? Another thing, why is it when i go in the city, i get full bars, and have no problems making a call, the minute i get home, everything goes dead?

When you say a "software flash", what does that mean?

So basically i can't sort the problem out with my vodafone network. I presume Sony won't take it back and sort it for me, seeing that i bought it from a Chinese seller? At this rate, the phone is worthless. Anything else i could do? This is a right pain in the neck. Cheers.

@berhenne52 contact the seller to check where he has the stock of phones from.
