[Sony Xperia P, U, Sola, Go] onlinegaming1821:
i just bought this phone yesterday and I'm experiencing signal drop when holding the bottom part (from 3 bars to 0 bar of signal and it is only happening when the signal is normal and not great). I went to the shop where I bought this and didn't replace my phone because the signal there is great and when I tried holding the bottom part, only 1-2 bars is dropping (from full bar of signal) and I tried their other stock of sony xperia P and signal drop is happenning also. Is that a faulty batch? thanks.
[Sony Xperia P, U, Sola, Go] MajestyZ:
No it's normal. It only happens when I'm inside my house for me.

It appears to drop, indeed, but I can still make calls and send texts.

This similar issue (if it can be called an issue) is present on the Xperia S as well. So no, no faulty batch.
[Sony Xperia P, U, Sola, Go] onlinegaming1821:
you are still able to send text?? on my phone when the signal drops, the text will not be send if I'm still holding the left side and if I remove my hand, the signal will comeback..

my other friend who have also xperia P didn't encounter this problem even they are holding their phone with two hands (holding like it is like the handle for the sword).. BTW thanks for your reply..
[Sony Xperia P, U, Sola, Go] Push_10:
I have my Xperia P for a few days now but today I noticed a weird spot at the left side of the transparent bar. (see attachement)

Anyone knows what this is? Is it harmless ?
[Sony Xperia P, U, Sola, Go] MajestyZ:
Perhaps your friend uses a different provider? Meaning more signal strength for him. Have you tried testing it in the same house, sitting next to each other?

If I want to let the signal drop, I have to hold it in a certain way which isn't the normal way to keep it in my hand, it's no issue for me.
[Sony Xperia P, U, Sola, Go] NABENDU1:
i mean in some previous posts a guy mentioned that bubbles had formed around the transperent bar on his phone ! he posted an image of the same ! i guess that this problem is the same with ur phone ! try and get a replacement asap cause it just destroys the look of this beauty !
[Sony Xperia P, U, Sola, Go] onlinegaming1821:
you are somewhat right. maybe this is because of my provider and xperia P must not be hold in the bottom part when you are using it.. I'm using it now using the right hand and it didn't drop any bar (practicing with right hand).. But I will go also to some concept stores and check their units..
[Sony Xperia P, U, Sola, Go] MajestyZ:
Indeed, give it a try in the stores and compare their units with yours.

I'm actually keeping my right hand around the bottom part a bit when I'm holding it, but it's not giving problems.
[Sony Xperia P, U, Sola, Go] Hellraiser76:
I updated my phone an hour ago...no loss of signal,no restarts and no problems so far.
[Sony Xperia P, U, Sola, Go] draugaz:
Just relax. To get lowest possible SAR ratings every manufacturer nowadays puts the GSM/UMTS antennas at the very bottom of the phone (as far as possible from your head).

So, if you hold your phone at the bottom, your hand acts as a radio shield effectively blocking the cellular signals. Is is just a plain simple law of nature.

Of course, there are differences. Ho big is your hand? How sweaty? Which direction is the nearest cell tower? What are alternatives, maybe there are other cell towers from the opposite direction? Which frequency is actually in use? 900mHz? 1800? 2100? Is the indicator even linear?

And if we factor in "other" manufacturers, there is one additional big question: how honest is signal strength indicator? Is there a special "magic" which simply obfuscates that signal drop in such cases? Many phones do such things, so the users who do not know physics don't *****.

Oh, and I forget: Xperia P has that beautiful aluminium unibody. So the only places where radio signals can escape it is that plastic part at the bottom and another plastic cap at the top of the phone (which is made out of plastic precisely for this reason).
[Sony Xperia P, U, Sola, Go] dohanotoha:
I have just re-updated my phone using the old update service software,not pc companion. No signal loss so far.
[Sony Xperia P, U, Sola, Go] SirRobin78:
Please test this overnight in GSM only mode - 3G is working without a problem so far on my german P. On GSM mode i´ve a lot of connection drops over the day...
[Sony Xperia P, U, Sola, Go] MajestyZ:
I'll give it a try for you tonight, I'll put it on GSM mode only.

Makes it a test to see the battery drop as well. I'll report tomorrow.
[Sony Xperia P, U, Sola, Go] Hellraiser76:
Will do tonight...so far not a single problem.
[Sony Xperia P, U, Sola, Go] dohanotoha:
:mad: the problem is not solved. Nothing will fix it but another update.
[Sony Xperia P, U, Sola, Go] Hellraiser76:
I got back from work and i turned it to GSM...so far in a period of around 4 hrs not a single problem.

Guess i am one of the lucky ones...
[Sony Xperia P, U, Sola, Go] MajestyZ:
Putting it to GSM-only actually improved my reception signal A LOT. From the 1 bar I usually have inside the house, it went to a constant 5 bars. This is what shows in my battery graph as well from last night. You can see clearly when I changed it from UMTS (prefered) / GSM to GSM only.

Fact is that one or two apps have been draining my battery last night, as it went from 51% to 28% in 7 hours of standby time. You can see it in the graph too, the phone keeps turning itself on while I'm not using it and the screen is off.

As I have Badass Battery Monitor installed, I keep logs of the battery usage per app, and it seems that it's the Google Sync Service that was causing the problem last night, continously trying to sync my contacts or something.. Gotta figure out a way to change the interval.

Here's the graph:

I have had a one time experience with losing the GSM connection signal and not getting it on anymore (red cross on the reception bars), even after trying to switch from GSM only to UMTS and such. It was restored after rebooting.

Seems like a big problem, indeed. I hope a new update will follow soon.
[Sony Xperia P, U, Sola, Go] inteks:
what app is that on your screenshot ?
[Sony Xperia P, U, Sola, Go] topazonic:
Same here, I have also experienced it only once. After a restart it was solved & never happened again. Hoping that the fix is released soon. Though I think that the battery has deteriorated a bit after the update.
[Sony Xperia P, U, Sola, Go] Hellraiser76:
Yeap confirming what the guys are saying...not only i dont have any problems with GSM,but i didnt have with 3G also,i also get better signal.
[Sony Xperia P, U, Sola, Go] bed-boy11:
Me too.
[Sony Xperia P, U, Sola, Go] SirRobin78:
So you are the lucky one without problems :)

It´s good to hear but i think it is a global issue in the latest FW and sony need to fix this as soon as possible.
[Sony Xperia P, U, Sola, Go] Hornet331:
No problem here either, maybe its an issue with certain frequency bands, my current provider uses following frequency bands for gsm:

[Sony Xperia P, U, Sola, Go] moizsami:
Guys what about the development of this awesome phone? can't live without CM and MIUI....i bought this phone as i though 2011 xperia lineup got huge support from devs. but this XP's development is almost dead with only one custom rom....

Does any one know if Devs are going to support this piece or not ?
[Sony Xperia P, U, Sola, Go] Mooozer:
be patient.

it is no highend device therefore does not attracht that much devs here, still there is yet a rom out, others to come. Device will get ICS this month, so it is possible devs wait to build on ICS rather than GB which would be outdated anytime soon.
[Sony Xperia P, U, Sola, Go] mic_:
There's also the fact that the P, U and Sola are based on a platform that hardly any other phone is using (the ST-E U8500). That probably means more work for the people working on custom ROMs, as I'd expect re-use of code to be easier across, say, two Qualcomm-based phones.
[Sony Xperia P, U, Sola, Go] AnkurTri:
Some of you are saying that the death grip issues are seen after updating it via PC Companion. I haven't updated it yet. So should I update it or not? I also talked to @Sony_india on Twitter and they said that ICS will come in mid July, just two weeks from now. So, should I update it or not?

PS - I'm having some death grip issues only when I put it in my back pocket but only sometimes
[Sony Xperia P, U, Sola, Go] MajestyZ:
There's no such thing as death grip issues after the update, only full signal loss issues without a fix except for rebooting.

You have to choose for youself whether you want to update it or not, I have no trouble using my phone right now while it's updated. I can barely wait for ICS though. I don't think it'll be mid July by the way, the end of July seems more legit to be honest..

@ Inteks: It's the standard battery stats that's integrated in the phone. Go to settings > about > battery usage, then press the graph.
[Sony Xperia P, U, Sola, Go] ste71m:
new update

new firmware certified by ptcrb

6.0.B.3.171 of 3 July
[Sony Xperia P, U, Sola, Go] topazonic:
Hello guys today I again faced the network drop issue two times. Now what I did was went into wireless networks settings, mobile network then set it to manual & selected my network & have not faced the signal drop since then. I think if it drops then it comes in the notification bar & can be connected back again. Though I am not sure that this completely solves the problem, I will confirm it tomorrow as signal drop happens for me when I am sleeping & phone is in idle mode.
[Sony Xperia P, U, Sola, Go] topazonic:
Nice, today only I emailed them about the issue. Thanks for the info. +1
[Sony Xperia P, U, Sola, Go] SirRobin78:
Thank you for that information! Let´s hope this is a fix for the buggy baseband and not only a special provider customization...and they release it soon! :good:
[Sony Xperia P, U, Sola, Go] AnkurTri:
Hmmmm.... The battery sucks, don't you think that ICS will use more battery making things worse?

It only gives 4 hours of battery backup on heavy usage and 7-8 in moderate usage. Any hacks and tweaks to improve the performance?

One more thing, I have noticed that it doesn't charge while playing games/browsing and charging it at the same time. The battery was 56%, I plugged in the charger and started to play temple run etc. And after an hour it was still 56, I've noticed it several times. Anybody else having a similar problem? please let me know
[Sony Xperia P, U, Sola, Go] MajestyZ:
I have applied it as well, let's see.

It actually worries me more that we're not able to fix it without rebooting the phone.

It's not that bad, the battery time. I've seen people reaching more than a day with moderate usage. I can get through the day with normal usage, which is fine for me. The 7-8 hours you're describing: I've had 'em too, when I had the phone in use for a week or so. How long have you been using it?

My phone charges when I'm playing games at the same time.
[Sony Xperia P, U, Sola, Go] AnkurTri:
I bought it almost a month ago. Is that the reason?

Looks like the charging problem is due to some minor bug, just hoping that ICS will fix it.

I know I'm demanding too much but if Xda can build a Jelly Bean custom Rom it'll be great
[Sony Xperia P, U, Sola, Go] kevinclint:
I have the same worry that battery life may reduce in ics compared to gb.

Fot my definition of heavy usage the fine lasts me for 7-8 hrs. Since heavy usage always means increased screen on time i reduce the screen brightness to 25% to reduce overall battery consumption rate.

But it does charge when playing games. Do u have the fast charger? Also if ur one is comparatively new gv it some time for the battery to get calibrated.

[Sony Xperia P, U, Sola, Go] AnkurTri:
I use that GreenHeart one which came in the box, and I keep it on power saver mode all the time, with auto brightness and only auto-rotation, mobile data and auto-sync turned on

By heavy usage I mean tweeting countinusly for 1-2 hours, followed by playing games and browsing (via Dolphin hd) and play store
[Sony Xperia P, U, Sola, Go] MajestyZ:
I don't think the battery time will go down with ICS, most likely will get better even, just like it did with the Xperia S.

Well a month is long enough for the battery to be working like I should.

Which apps show high battery usage in the battery stats?
[Sony Xperia P, U, Sola, Go] kevinclint:
Yes a greenheart one. But it us an ep800 or an ep850? 850 is the fast charger with higher mah. Try keeping it on a fixed brightness of around 25% and see if battery life improves. U can always go back to old settings if not pleased with d brightness. Also i assume u gave a gsm only conn? Then switch ur phone to gsm mode only an if u have good signal reception set the network selection mode to manual and select your service provider.

I will post my 7-8 hrs battery consumption in a while.

[Sony Xperia P, U, Sola, Go] topazonic:
It will give you a notification in the notification bar. Just tap that and you will get your network back. This happened to me once today & this did the trick for me. I guess we will have to stick with this until a new update is available for our phones.
[Sony Xperia P, U, Sola, Go] MajestyZ:
Ah well, it didn't give me a notification last time it happened to me.

I hope the update will arrive soon enough.
[Sony Xperia P, U, Sola, Go] AnkurTri:
I never noticed until now, it is ep800, should I buy a new one?

Yes, I keep 3G off most of the time, will try the 25 % brightness thing
[Sony Xperia P, U, Sola, Go] AnkurTri:
Yahoo mail, Twitter and Play Store according to Onavo Count
[Sony Xperia P, U, Sola, Go] topazonic:
Yep, here is the link to check new updates for our phone.

Here:- http://www.ptcrb.com/vendor/complete/view_complete_request_guest.cfm?modelid=21034

As it is already certified it will available soon.

Hi I got a question about photos and videos widget.

When I added new pictures it auto updates the widget, but when I delete the pictures it doesn't, the deleted pictures are still showed up in the widget, and it's very annoying.

So can u tell me how to fix that? Thanks

// The problem seems to occur with the default gallery app as well. I replaced it though.

// And the 'like this track on facebook' thing of the music app only works with a few songs. I don't know why either :-(
[Sony Xperia P, U, Sola, Go] AnkurTri:
Yup. Same problem here, maybe the update can fix it. I also use an alternative gallery app QuickPic
[Sony Xperia P, U, Sola, Go] kevinclint:
It is always better than the ep800. But i dont think it is available separately. I had a ep800 earlier too but then had to exchange my phone and got a ep850 with the new box. Any chance u van ask sony for a replacement due to some fault? Then u can lodge a complain and try and ask for a replacement.

My stock gallery app always gets refreshed automatically after every delete. Try deleting the widget and reinstalling it.

[Sony Xperia P, U, Sola, Go] AnkurTri:
I can try. The charger seems fine, have to think of a valid reason to change. Thanks :)
[Sony Xperia P, U, Sola, Go] kevinclint:
Posting my 7hr battery stat. I am quite pleased with the battery of my Xperia P as I go through some heavy usage from the time I have brought the phone. It is just so addictive. :laugh: Have still not been able to use it under the normal usage.

I get 7hrs with around 3hrs of screen on time, GPRS contuinuosly on and downloading in the back ground, 1hr of calls, 30mins of whats app msging while it is still on in the back ground, fairly high browsing for around and hour on Dolphin and a news app, and around 10mins of Temple run.

I just hope that the battery improves further with ICS.
[Sony Xperia P, U, Sola, Go] MajestyZ:
Your pictures don't work for me, is it me?

Perhaps you can get the EP850 somewhere off the internet, or eBay.

Can you guys tell me which USB cable you're using to charge your phone with? Mine is kinda broken (out of the box), 'cause it stops charging when I move my phone even a tiny bit. A Blackberry usb cable works just fine, no problems whatsoever, so it's not my phone connection, which I was worried about.

But, I took the label off my cable when I received it. I can order a E700 or a E600 from a dutch website. Which should I take?

Edit: EP851 seems available here, perhaps it's available in your own countries webshop as well: http://www.sonymobile.com/gb/products/accessories/quick-charger-ep851/
[Sony Xperia P, U, Sola, Go] onlinegaming1821:
i can get a day and a half when using it normally.. and a day of heavy use (heavy use for me) 1hr e-book reading, 2hrs games, all-day text.. my brightness is at 0% because it is so bright..
[Sony Xperia P, U, Sola, Go] onlinegaming1821:
i would like to ask if I need do drain the battery to 0% before I charge it? because I usually charge it for to hours when it says time to charge (usually 15% remaining).. thanks :cowboy:
[Sony Xperia P, U, Sola, Go] topazonic:
Yep, I agree it's already too bright, so I keep it in power saver mode & auto brightness. Now I will try with 0%.
[Sony Xperia P, U, Sola, Go] topazonic:
Nope, the newer battery does not have such requirement afaik. They automatically adjust.
[Sony Xperia P, U, Sola, Go] AnkurTri:
I also use the USB which was provided with the box, it is very small, so it becomes frustrating when you want to do something while charging it.

I haven't tried the 0% brightness, will try it.

I once used the USB of BB Curve 9220 and it worked very well

Perhaps we should buy the ep850 charger with BB USB cable. Maybe that can enhance the performance
[Sony Xperia P, U, Sola, Go] AnkurTri:
The current battery is 36% after a 3 hour usage :-(
[Sony Xperia P, U, Sola, Go] jebas15:
Today i submit my phone in service center for replacement. i have problem in FM Radio. Fm Radio is not show any channel. If i manually tuned some station that also not working. anyone have this problem?
[Sony Xperia P, U, Sola, Go] dhansiddh:
what is the color of ur device that u have sent fr replacement if its silver then u will not get a silver coloured device as its not available in the stock currently in india......which is the case with me........
[Sony Xperia P, U, Sola, Go] AnkurTri:
No, I don't have it (yet)

Go to the store, they will replace it
[Sony Xperia P, U, Sola, Go] hpsauce37:
I have a silver xperia p supplied by o2 but is an unlocked generic device that I am using with my orange contract in the UK. Only ha this phone a day an already thinking it needs to go due to the terrible signal drop an inability to hold a signal and also the buggy slow software. Such a shame as its a beautiful device and really though this would ne my perfect phone. Big let down by Sony again.
[Sony Xperia P, U, Sola, Go] kevinclint:
I cannot see them too. Wonder why. Im reattaching them here again.

Well I have removed the tag off mine as well. But I read it somewhere in this forum that the fast charging works only with the EC480 USB cable so you might want to get that one only.

It should be available in India too as it is on our contry's website as well. Here's the link t the indian website. Anyone interested can call Sony on the toll free no. 180030002800 for more info about your respective area.

http://www.sonymobile.com/in/products/accessories/quick-charger-ep851/

They told me the same for the Black device when I asked for a replacement. I threatened to ask my money back and go to consumer court for the inconvenience they were causing me and the next day they somehow arranged for a Black one.
[Sony Xperia P, U, Sola, Go] kevinclint:
I have signal drops only at home and thats because the reception itself is poor in the area. My previous phone did no better.

As for a "buggy" software. I havent ever experienced lag on the Xperia P ever. I minimize games (FLCommando, Temple Run) and browse whatsapp, gmail while its in the background. All this while connected to my HDTV.

Maybe you should try out a different piece as this seems to be specific to your device.

//Im on the older firmware though, version .564. A few users who upgraded to the newer firmware had experienced signal drop.
[Sony Xperia P, U, Sola, Go] hpsauce37:
I have no means to exchange this device as I'm not the original owner, it seems from what I have read generally that unless you are in a particularly strong signal area that the signal drop is only evident in weak areas. It just seems that this device is very weak at holding onto a signal. I have very few apps running and the latest update, WiFi connects/disconnects at home to the point where it's unusable. Don't get tweet notification sound from twitter although I believe it's activated (always worked on my one s) constantly get error connection messages when in the play store also. And all this within 2 days of owning
[Sony Xperia P, U, Sola, Go] halfmanhalfmachine:
I have had mine just over a week.

Pros:

*Red version looks amazing.

*Fast charging is great!

*Camera quality is fantastic.

*Screen is bright and clear.

*Battery is decent. On par with HTC Hero and Desire HD. Better than Nokia Lumia 800.

Cons:

*Doesn't have ICS.

*Buggiest version of Android I have ever used. Possibly worse than a 2.3 ROM on HTC Hero.

*The Mac bridge software seems to be written by the same developers as SonicStage. Full of bugs and things that don't work.

*Lots of pre-installed crapware.

*Hardware buttons are a bit stiff.

*No search button.

*Build quality is suspect. Mine seems to be OK, but I see slight hints of issues that other people are reporting such as LCD bleed (or white distortion) and gap between screen rim and aluminium body.
[Sony Xperia P, U, Sola, Go] zeefung:
I have been using my Xperia S for a few months , and, wishing to enjoy the White Magic technology, I have just bought an Xperia P.

But to my disappointment, the screen of the Xperia P is noticeably more yellowish than my Xperia S!! I think pure white color is fine, but with grey color, the Xperia P's screen will show up as grey+slight yellow color tone. Although many people complain the Xperia S has yellow tint / yellowish screen, in fact when putting the Xperia P and Xperia S together one can easily distinguish the colour tone difference - the Xperia P is much more yellowish than the Xperia S.

Don't know if all Xperia P users experience the same problem or it's just me, so I should go back and exchange another unit?

Another thing is , the Xperia P's battery life is just so much worse than the Xperia S..
[Sony Xperia P, U, Sola, Go] dhansiddh:
hey kevinclint they are giving me a red xperia p instead of my silver one i have not collected the red device yet....but pls suggest me how could i get my silver color device or should i go for any other color????
[Sony Xperia P, U, Sola, Go] kevinclint:
The problems you are facing seems to be device specific and something sme other people have faced as well due to bugs in certain firmware versions. What firmware version are you using? have you tried upgrading your firmware version? I have .564 and thngs seem fine on that.

Call the service centre on 180030002800 and give them the reference no for your complaint if u have a DOA. Else just give them the location and shop details you have bought the device from.

Not that the red is not good looking, but to me the black just looks perfect like a mini Bravia HDTV and a Dark Night. :D Also it wont make stains and dirt as visible as they are on the red and silver in comparison. IMO.

Not defending the P here but try updating the firmware. My previous phone running on an earlier firmware had the same problem of apps crashing, lags, etc. This new replacement running on .564 runs smooth.

I believe the keyboard that pops up when u long press the menu button functions as the search button. Give it a try.
