I purchase this phone a few months now back in 2011-2013 this phone is amazing a lot of developers are working and customizing this phone. I watch a lot of video how to root installing custom rom upgrading and tweaking. After installing customizing rom and some experiment I end it up go back to stock firmware. Reason why. Yes it will boost the performance of your phone but it’s not really stable sometimes the functionality of the phone will ruined and end up to boot. This is my personal opinion and experience only. However on stock firmware what you can do is root the device and install CWM it will work fine. I have a lot of hd android games install to my xperia mini pro and Im trying to do the same thing in xperia play.
Using this phone in 2020 is still fine at least for me im not in to online gaming. I use this phone for emulation such as Nes, Snes, Gba, GB Color, Sega genesis, PS1 (not all of the games run smoothly) some HD android HD games and for call and text sometimes Facebook.
I hope Sony the make another phone like Xperia play with controller like this added L.1.2.3 and R. 1.2.3 trigger 2 analog stick. Updated android version. Bigger internal storage 256gb to 1tb will be awesome!!! A card slot up to 1tb, 6gb to 8gb ram, 4000Mah. 20 mega pixel front and back 4” to 5” screen is fine. Chipset Qualcomm Snapdragon 865, CPU Octa-core (1x2.84 GHz Kryo 585 & 3x2.42 GHz Kryo 585 & 4x1.8 GHz Kryo 585) GPU Adreno 650. 3.5mm jack.
I’m kind a crazy after thinking of this spec XD. But hey it will be a perfect phone who love emulation and hd android gaming.
