So its been almost a month since we, the Xperia P users received the jelly bean upgrade.
Although the update was welcoming, it still had some problems.
Listed are the issues that need to be addressed.
BUGS:
1. Notification Tone bug still exists.
2. General/Silent Mode bug.. this happened in my phone, i'm not sure whether everyone has it. if i put my phone on silent mode, and make a call, the phone again reverts to general mode.
3. Walkman sometimes goes back by 3-4 tracks while scrolling for next song.
4. Album App not showing pics.. I do not have this bug, but i hear many others are.
IMPROVEMENTS:
1. can the toggles in the notification bar be shifted a little more down?
2. Can we get back the Black background? i dont mind the white background, gives a little richer look, but kills me to operate the phone while goin to sleep when the lights are out.
3. Dialer and Call log Lags.. this is a serious issue.. have to wait for nearly a minute to make a call. same for accepting calls.. no tone plays for nearly the first 5 seconds, the phone just vibrates.
Last but not the least, the most biggest issue.. UPGRADE THE BATTERY.. its impossible to provide a good backup with the 1305 mAh battery no matter how light software you develop.
Any more suggestions.. Please comment.

- SMS/keyboard bug - (Sometimes during I type sms, when I press 'smiles' button, the 'smiles board' is displayed under the keyboard... It's a graphical bug. I don't have a screenshot yet, i will add it when I see that bug. - I don't now yet, still testing.
IMPROVEMENTS:
- working LED Notification in Stamina Mode (the colour of the light can be changeable) - 6.2.A.1.100 has't added any functions - only bug fixes.
Hello friend, maybe I have a different perception about the terms "improvement" and "bugs".
You have listed in your recommended improvements as the last point " Dialer and Call log Lags".
When you click(tap) on the name of the person that you want to call, sometimes, you can't close the comunications, the other side is talking and you don't have the button to close.
Try to tap two times one number of the your telephone address book ...when the telephone is stuck, look.
Maybe is more important to change the skin in black(i prefer white) or shift the toggle in the notification bar(i would prefer to take off them only occcupay space).
About your bugs ... i don't want to comment they, but ok, someone have the solution but you could solve by yourself or wait for a bug fix.
I am kidding, but this is a TELEPHONE and the most important an the most urgent, it's the CALL LAG.
Someone use it like a telephone(it is not walkman) and make and receive calls.
Customer satisfaction is not my field but we have to make constructive complaints.
I like japanese tecnology, only buy it.
I also understand the developers, but it is a BIG BUG.
I forgot about the battery, the slogan should be:"for the miracles we are preparing".:smileyhappy:
You have a beer paid.
On the same boat here. I'm just tired of this phone, I'm a Sony fan but this will make me try another brand.
I also forgot about the NFC issue.. 
Updated my post (no. 2).
Some bugs is fixed on 6.2.A.1.100:)
Has anyone got this bug?
On 6.2.A.1.100, when I use Quick Shot/Launch camera - sometimes i get a message 'Error! Camera not available' 
The problem is ONLY when I use Quick Shot/Launch on locked screen. When I normaly turn on, by using Camera from menu, everything is ok.
I will install the update later and check this.
Ok, here is my topic with better explanation:
Well,5 times in a row started fine,I do not know which may be your problem...
i too tried it 10 times just now, no issue. Please re install the firmware and do a factory reset after the device boots up and after the first boot let the device settle down DONOT PLAY WITH IT THE MOMENT IT STARTS KEEP IT ASIDE FOR 10 mins
