[Xperia SP Q&A, Help & Troubleshooting] Gamer4Life:
Hello friends, i am new here, i bought xperia sp 5303 last week from a friend, it's unlocked, updated firmware from update center to the last version and did factory rested from settings to delete all my friends data.....

before you start reading, this is long post, please proceed if you intend to help a helpless newbie like me :( that has a lot of questions and problems with his first first andoird phone

a week has passed and discovered a lot of problems with this phone i hope you friends here can help me with :

first before the questions, i suspect that al these problems are beceause of the orange modified firmware 4.3 207, it has countless orange apps interfering with sony stock apps, and make the phone useless without the original operator simcard(orange france) but the phone is imported, so we have a different orange here :( and it doesn't work with the integrated apps.

1) battery back up is very bad, about 2.5 to 3 hours when browsing on 3g and playing 15 minuts subway surrfer. after long night charging, if i plug off my phone in the morning from 100% it decreased to 99% in less than a minute, on 3g browing it decreases at the rate of 1 to 2% per minute at the first 10% then at the rate of 1% per minute approximately....

2) wifi range is awful compared to other phones, my symbian phones has much better range, and more stable wifi. Signal drops from full to one bar ( note that the router is about 4-5 meters away) if i go further than 10 meters, it i=will start disconnecting from almost full signal to one bar, then disconnects, and i have to onnect it manually from wifi settings. this is a nightmare as a java based samsung phone, keeps a stable 1 bar signal without disconnectings, and my xperia sp keeps jumping from almost full signal to empty, then disconnects in one minute, then it says wifi out of rance, then it comes full signal for few seconds, and same story again. my brothers GS4 and other friends phones( Xperia M2 , !xperia Z3 compact) has laptop comparable wifi range, when my phone doesn't detect anywifi, theirs detects our college wifi with 1-2 bars, very stable and fast.

i thought wifi problem existed only in 4.1.2 after google and other threads in the forum here

4)) camera is blurry when it takes the first pictures and it doesnt focus how it should focus, and takes a blurry photo, but it takes good photo in the second try, but this is frustrating, as i have to take two photos to get a nice one, if i move the camera to another focus range

3) i want to install international rom for my phone Xperia sp C5303 (this if possible, as pc companion won't do it even if i changed region ) , root it and how to make clean install to get rid of all the orange traces and wipe them from my phone.

i want to kknow the steps needed to make a clean install

i spend the whole last night reading tutorials and stuff on the forums, but every thing seemed like it's in another language, as this is my first android phone, all the vocabulary used here i couldn't understand, and it was too much to get all the info here in one night. i installed pc companion, flash tool, and downloaded a rom from here, it says 4.3 207 AU(it's the only one available, Au is australia apparently but i want something international, or europe firmware )

please guys help me, i am a total noob, and doing my best to understand this and catch up with you, but i need time, i gave up on symbian finally and now it's time for andoird

also what is the best stock official rom , i want good battery backup as advertised , on gsm arena they say it should last 6 hours when browsing the internet, my phone lasts less than half, tho it's not even 1 year old

also guys can you explain what are the cwm and kernel ,and recoveries and what are the benefits of these. i plan to use the phone on stock and play with it few months then pass to custom roms if possible
