[Xperia SP Q&A, Help & Troubleshooting] the_helix:
I had written this on another website from where I purchased my SP. This may help.

-------- Xperia SP vs Galaxy S3 vs HTC One X/X+ ---------

1. Design: I just can't accept the design of S3. Few may like it, but most of you will agree with me. X is the best in looks with SP a close 2nd.

2. Ergonomics & Build: SP is the thickest & heaviest of the lot, but it is shortest in length & width making it easier to handle. The difference in size is significant between S3 & SP. In fact S3 is bigger than S4. Build quality for all three is very good.

3. Hardware: SP has the best processor & GPU & beats the other 2 hands down in benchmarks, gaming & web browsing etc. RAM is same for all. SP’s inbuilt memory is only 8 GB (5.3 GB user accessible).

4. Screen: All 3 have same resolution & great indoor performance. S3's super amoled & X's LCD2 easily beat SP in outdoors.

5. Camera: All 3 have 8 MP and decent "good light" performance. S3 is a clear winner due to better low light performance. SP is the worse in low lights which probably is due to bad software. Future updates might correct it. SP's front camera is VGA.

6. Software: SP comes with Jelly Bean whereas the other two were launched 1 year ago with Ice-cream Sandwich & are about to receive Jelly Bean. Nobody knows if X & S3 will get Android 5.0 Key Lime Pie. SP will surely get it as Sony is better in providing upgrades.

7. Battery: The most neglected aspect of a smartphone. SP outperforms both. Once you turn stamina mode on, it does even better. S3's battery is removable - a slight advantage. Check out the battery tests for all 3 on GSMarena.

8. Price: SP can be bought for about 23K outside whereas S3 will be around 27K, X+ about 29K. I am only listing X+ here as the Flipkart price for X (32 GB) is much higher than X+ (64 GB) which is stupidity. X (16 GB, no expandable storage) is not worth considering.

I chose Xperia SP coz:

1. Design: The transparent LED makes the Xperia SP a real looker. Silver power button also adds to beauty. There are little gaps between the phone & back cover on few places, reducing a point.

9/10

2. Ergonomics & Build: The aluminium frame enhances the build & the rubburized plastic back cover improves the handling. On the front, the edges are a bit sharp for a phone reducing points.

8/10

3. Hardware: Xperia SP has the latest S4 processor & Adreno 320 GPU. The GPU is same as Xperia Z/ZL & HTC One & is the best in current mobiles. Resource hog games like Asphalt 7, Dead Trigger, Real Racing, GTA Vice City etc. work like a charm on SP. You can look up videos on youtube for it. Also, if you own a PS3 you can use its controller to play games on Xperia SP too. If you want to have too many big games on your phone at once, internal memory might be short.

9/10

4. Screen: Sp has really sharp 1280 * 720 p (HD) screen. Bright enough for indoors. However, in outdoors, the reflections from the screen are annoying. Viewing angles, though not as good as the other 2, still are good enough for a mobile which one mainly uses face on & not while keeping it tilted.

8/10.

5. Camera: Xperia SP gets the least points here due to all I wrote above. However SP takes nice pics in good lights & for low light condition like parties, better to use a digicam. Even Lumia 920's camera won’t excel in dark. The front VGA camera might be a helpful in reducing your 3G data charges due to low resolution.

7/10

6. Software: Jelly Bean is very sweet. Sony also has gone for the minimalist approach, which benefits SP's performance. For other apps the great Google Play is not far away.

10/10

7. Battery: The standby time of SP is not as good as its talktime, web browsing or video playback times, which are simply great. Also as the phone is 10 mm thick & the battery is non removable, a larger battery like 2600-2800 mAh would have been nice.

8.5/10

8. Price: 10/10

Sony has delivered a masterpiece with Xperia SP. I am giving it 4/5 overall only due to 8 GB internal memory, bad main camera & VGA front camera. If any 2 out of these 3 aspects were better, I would have given 5/5. If you are more into gaming, web browsing, watching movies on your phone then go for it.

If you want a large collection of heavy HD games, give S3 or One X+ another thought. This is because Android 4.0 onward u can’t move the apps to SD card. Here Xperia SP's limited inbuilt storage might be a problem. Though you can always keep the songs, movies & default storage of camera on your SD card.

If camera is your ultimate goal then forget it, buy a cheap phone & get a nice digicam.

If you can stretch your budget, get Xperia ZR. It is water & dust poof, has 13MP, better processor & 2 GB RAM.
