Hi all,
I seem to have an issue with my Xperia V. I'm located in Sweden and got the phone from Telia in February. Last week when I was trailing in Austria the phone suddenly crashed. The screen turned yellow/greyish - than it rebooted. After a minute or so the phone was back but didn't dial into the GSM network. I didn't spend too much though on it as from time to time roaming might not work at once for my anyway. After a couple of minutes I ran out of patience since I had to responded on some mails and make calls and put the phone in "search networks" mode. After a very long time it offered me 8 or 9 networks (two 2G, 4 3G and 2 LTE networks). I selected the A1 3G as I knew LTE won't work in roaming and A1 usually is my roaming partner in Austria.
The phone connected and I received and send 2 mails, then it dropped out again. I started again searching networks and put me back on the A1 3G. Continued the story all night… I blamed it on the roaming and the next day when I was back home in Sweden all looked fine - the phone directly connected to Telia LTE/4G. Riding the train home I left LTE covered territory and saw the phone did not connect to 3G automatically. Putting in the network manually worked. Slowly I started to worry...
Back at home I see my phone is losing signal a lot. The interesting thing is I can put it back on the network always manually but it feels strange.
When I looked a couple of minutes ago:
13:48
Network: Telia S
Signal Strength -95dBm 9 ASU
Type of network: UNKNOWN:0
13:49
Network: Telia
Signal Strength -109dBm 2 ASU
Type of network: HSDPA:8
13:49
Network: Telia
Signal Strength -83dBm 15 ASU
Type of network: HSDPA:8
13:50
Network: Telia
Signal Strength -83dBm 12 ASU
Type of network: HSDPA:8
13:51
Network: Telia
Signal Strength -103dBm 5 ASU
Type of network: HSDPA:8
13:52
Network: Only emergency calls
Signal Strength -87dBm 13 ASU
Type of network: UNKNOWN:0
Now I had to browse networks and was able to put it back onto:
13:53
Network: Telia S
Signal Strength -85dBm 14 ASU
Type of network: EDGE:2
13:54
Network: Telia S
Signal Strength -89dBm 12 ASU
Type of network: UNKNOWN:0
I also find it interesting that just a couple of minutes ago the phone showed only 1 to 0 bars connected to
Network: Telia S
Signal Strength -109dBm 3 ASU
Type of network: UNKNOWN:0
I made a call and the signal jumped up:
Network: Telia S
Signal Strength -85dBm 14 ASU
Type of network: UNKNOWN:0
But after call finished it stayed up until the phone went into standby. Next time I checked a minutes later it was down to
Network: Telia
Signal Strength -107dBm 3 ASU
Type of network: HSDPA:8
I suppose the phone controls the power to the GSM chip somehow which doesn't work properly anymore. I already did a couple of factory resets hoping this would make it better but I don't see any difference.
I called to the Telia service desk but they told me the phone is on the latest software so not much they can do - I have to send it in. As I need the phone on business I can't just send it into some lab for testing and get it back weeks later without a replacement. Also I'm worried they won't find any issues as the phone works if you take a quick check. From some bad notebook repair center experience I know that most of those repair centers don't spend too much time on individual problems and as soon as they turn on the phone and it will be connected to a network they will flag it as "sure, works" and send it back to me.
Any ideas what I can/should do? Could it be a cell tower issue? Another phone lying direclty next to it was on full signal strengt while mine showed no service. No service is actually not true anyway as putting it to on a network directly connects it...
Thanks,
fassy
