Hi ,
Please see the Android Device Compatibility wiki for a non-comprehensive list of devices Unreal supports. I searched the wiki for your device, which is also known as the Galaxy Ace Style, and we do not have that device in-house and have done no specific testing for it. However, the wiki groups devices by GPU, so you can compare your device’s GPU with the devices we have listed, and get a good idea of how your project will perform on that device. Depending on which kind of Galaxy Ace Style you have, your device has some edition of Qualcomm Adreno GPU (probably either the 200 or the 306).
I hope this helps! If you have any other device specific questions, please return to this thread to ask. Thanks very much!
