Keep loosing GPS signal, normal? - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

Don't have much experience with this, but was surprised at the number of times I lost GPS signal. I was driving in an area with no tree coverage on a clear day. Why would the GPS signal drop multiple times?

i have already start a thread about the GPS in the forum...

[Q] How accurate is your GPS with out wifi on?

I ask because with my iphone 3g It was pretty much spot on all the time. My atrix on the other hand is about 4-5 blocks(WTF) off. This is only my second smart phone but this seemed really odd to me.
Anyone else with inaccurate gps with out wifi on?
Mine is usually accurate to within a few meters, but I don't let it use wireless networks for it basically ever
I played with this a bit more and for what its worth it turns out that if the gps cannot get a satellite connection it does not warn you. For me it was just defaulting to the center of the very small town that I live in. Which is pretty much within 4 block range no matter where I go. The 'Navigation' app does warn you if it cannot get a connection.
So yeah, the gps is good, when it connects
GPS is usually within 20' for me. Wifi is useless w/o a wifi source to connect to. No wifi when I'm out running on trails. And if I'm at home, don't really need the gps.
My GPS is dead on all the time. Only takes 3-5 seconds to get a lock at about 3m and that's indoors. Only time I've ever had a problem with it was while using shopkick in a deadzone inside Wal-mart.

WiFi Signal Drop & WiFi Analyzer

Noticed something interesting about the random drops in WiFi signal strength. I have had the problem others have reported where you can be sitting in the same place and suddenly the wifi signal strength will show that it has dropped to a much lower strength.
However, recently trying to see what the actual signal strength was I open the free WiFi Analyzer app from the market and went to the signal meter window. I noticed when I did that that signal strength indicator on the Prime jumped back up. I have been able to repeat that scenario multiple times.
I don't know enough about WiFi to give a reason why, but I thought I would throw what I was seeing out there to see if someone else more knowledgeable might know why and if it might help lead to a possible solution.

Poor signal

My i9205 have generally poor signal compared to my note1. It doesn't seem to make any difference to turn of LTD. I have not experienced any call dropping, only referring to the displayed signal. My note shows full signal while i9205 shows minimum signal. And in battery usage the "Cell Standby" is quite high and normally with 10-20% "Time without signal" even if I have not noticed any time without signal.
Anyone have similar issue ?
I have the Mega GT-I9200 and experience spotty signal as I drive around. I am on T-mobile in New York. Within a 15 mile radius in New York City my signal will fluctuate between HSPA+, Edge, G (1st generstion GPRS), and sometimes complete loss of both data and cellphone signal. I think the issue is I might need a modem to be ported from a t-mobile device to give me a consistent signal. Not sure if anyone could do that or if there's even a t-mobile device whose modem would be compatible at this point.

Yep! I'm definitely getting this too. The phone very rarely shows the full 4 bars of reception, and in low signal areas (1 bar or less) the phone starts flipping between GSM/WCDMA (UMTS) constantly, giving very poor reception. Also, signal strength in general isn't as good as my nexus 4 was. I sometimes am unable to reliably maintain a signal at all in areas that I know my N4 could reliably hold 1 bar of strength, with the phone disconnecting from the network completely and then reconnecting all the time.
As I'm in the UK and without LTE anyway, I've switched the phone to WCDMA mode only, which has helped though the phone now just flips between HSPA and HSPA+ when in poor signal. Its certainly much more usable this way at least.
On the upside, yesterday night with 3 bars reception I was consistently able to get over 15Mbps download, with my best result of nearly 19Mbps! So it doesn't look to be a hardware issue.
I'm speculating wildly here but to me this looks like a SW issue in one of two areas: signal strength isn't being reported correctly (too low), causing the phone to take action to try and obtain a better signal (by flipping to a lower bandwidth protocol or disconnecting and trying to detect a better macro, for instance) when it isn't really necessary OR maybe the phone is just too aggressive in switching from HSPA+ down to GSM to save battery.
Is there some way to take control of the mechanism, and try to force the phone to stay in hspa+, or to spoof a higher signal strength?
EDIT: This phone is packaged with very thin plastic wrapping over the metal band that runs around the circumference of the device. I accidentally left a lot of this wrapping on for the first few days. It may be complete crap, but I think my signal might have improved since I removed it all! I certainly seem to be able to maintain a connection in places that I wasn't able to last week, and maintain a constant (4-5Mbps) HSPA+ link in areas that I couldn't before...
Time will tell...
I have the same encounter, I have two sim cards belong to the same number one for phone and one for tablet. The one in Mega 6.3 give me three bar signal but the one in Galaxy tab plus 7" give me four bar signal :crying:
I am also having reception issues with my mega 6.3 I get worst reception than any of my other phones sitting in the exact same spot. I am on ATT in the US. I removed all the plastic around the phone. I am wondering if it is my APN settings. Hopefully someone can shed some light on this or there is something eles going on.
The Mega has an issue with the radio. I bought two of these an i9200 and i9250. Both Mega's would lose signal completely. I don't have the greatest signal here at my home, but it has never been an issue with any other phone such as Note 1 and Note 2 and many others. If you are in a weak signal area more than not, you may wamt to hold off until the radio issue is resolved with software or whatever. They were unusable for me and I re-sold them.

I have an i9205 and it's fine with the signal. I'm in the UK though
The big problem about this is that the phone uses much more battery when signal is low and using 3G. I can get 6-7 hours screen on time on one charge while wifi is on. But when using 3G with low signal I get 3-4 hours.
I hope this is a radio firmware thing, and not a hardware thing, so that it could be improved with updates.
so any updates?
Same problem here with my new Mega 6.3! My phone have only 1 or 2 bars signals while my brother's Samsung Grand has full antenna easily. It's very annoying. What should we do?!
Same ****ty reception going on with mine. I returned it.
I changed it too. New one is working fine.
hi. ah really? changnig phone u noticed a consistent improvement in reception?
but... i can say that i and my girlfriend, using a DIFFERENT SELLER...... we have the same problem of cell standby
I found that all phone models are inconsistent in radio reception, not sure why...
Sometimes the updates can do a little better, but I believe the hardware is the most limiting factor.
Maybe Mega isn't for you where you live, just return it then get another phone
i have poor signal Too
Any news or solution ?

{Q} Why does my phone jump off LTE as soon as I touch it?

This might seem like an obvious case of signal strength, but I have to ask because it bugs me. If i'm inside my house and my phone is sitting on the arm of the couch or something where I'm not touching it, I'll turn it on and it says I have 4G LTE with 3 bars. Less than a minute later, it jumps off of LTE and goes to 4G with the same signal strength. I thought it might be the radio, so I updated to the 4A.16.3250.24 radio suggested in the radio thread, and it still does the same thing.
Any ideas, or is this just a signal strength issue?
EDIT: Happens outside, too.

[Q] P760 Weak GPS Performance

I have an P760 with unmodified stock rom, 20b is the latest I can get here in Slovakia.
It takes really long for the GPS to catch some satellites, with clear view of sky, AGPS and data enabled, I usually get a fix in 90-100 seconds, which seems like really alot to me. Also, after I get the signal, it drops really easily. I was using 'My Tracks' from google to track my movement in the nature, on foot and on bike. The thing is, GPS has lost satellites for around 2 times in 30 minutes, so I have very incomplete and inconsistent results.
I've tried playing with the secret menu and GPS Status app, with no luck.
Is there any software, or even hardware way to increase the performance of GPS? I think there may be some problem with antennas.
Thank you.
