[Sony Xperia C5 Ultra] JKWR:
Ok so i've had my C5 Ultra for a few days now here in the UK and have had a few ups and downs but i've solved the problems I had with the phone.

I'm coming from the Z3 which I had an original sandisk 128gb micro SD card in. (Bear in mind I have tried several different Micro SD cards and I always buy original good ones)

Problems I had:

1. With the Z3 taking pictures was very quick whilst having the default storage to Micro SD card, DO NOT set the camera storage to micro SD on the C5 Ultra it takes 5 times longer to write to the micro SD card than the internal memory, so if you want to take photos in quick succession then don't save to the external memory.

2. Again an external micro SD card problem.....I have lots of apps and games, games especially taking up loads of space. I thought id be clever and install some big games and use lollipops feature of transferring them to the external memory to gain some space. This will slow the entire system down. DONT DO IT TRUST ME, pick your favourite apps and be done with!!

3. I have a Sony Smartwatch 3 and paired it with the phone and installed the Lifelog app. Currently (10th September) this app will slow your C5 Ultra down, it may not be optimised for Mediatek processors yet. Id wait for the app to be updated before you use/download it. Use the Google Fit app which works fine and can be left on even in stamina mode.

4. Don't expect the battery to be as good as a Sony Xperia Z3, its close and you will be happy with the C Ultras battery life but don't expect flagship battery life. (this may change as the battery on my C5 Ultra has not been run in plus I've been using this phone constantly!! Also the phone is on 5.0 lollipop and not 5.1.1 so the memory leak bug is probably there.) The good news is the battery life is better than the Z Ultra!

5. The phones 3g/4g signal is pretty weak, I thought the Z3 was bad but this is worse, hopefully in the next firmware update this will be resolved.

6. The takes a long time to charge. Probably about 3 hours from flat, quick charge plugs dont charge it any faster.

7. I miss the magnetic charger and the dock, im a massive fan of these. I have the dk52 dock for the c5 ultra but im always weary ill scratch the case around the micro usb.

The good:

Being a heavy phone user and my previous phones being : Xperia Z, Z Ultra, Z2, Galaxy note 2, 3, 4, Nexus 6 and Xperia Z3 I can honestly say now that I have solved the phones problems, this is the best phone I have owned, its the perfect size and price for me.

1. The Screen is gorgeous, its that bright i have it on the lowest setting! Picture quality is great even at near harsh angles.

2. Both cameras are great, youll need patience with them, dont be expecting to be taking great sports shots though.

3. the in call speaker is better than the Z3, id go as far as saying its the better than the Z series!

4. I got the official dock as well and love the portrait orientation.

5. Games and movies look brilliant in landscape and apps are a joy to use on this 6" screen.

6. Bluetooth music quality is brilliant, I stream to another stereo via bluetooth and the quality is near cd.

7. That selfie cam is brilliant, great wide angle shots and finally great selfies on nights out with low light!

As you can see the Phone completes the rest of my Sony setup (Yep my whole house is a Sony Shop LOL!)!! Anyway, enjoy and if your after a phablet sized sony phone then this is the one to have. Thanks.
