Android SDK preview won't work on Lenovo

Ok, I have some **** phone, Lenovo A 319.
Before that phone, I had a Samsung S3 mini. S3 mini was the worst phone that I ever had.

1.) S3 mini runed Epic Citadel without any FPS drop.
Lenovo can’t run Epic Citadel, it crashes on loading, or when I start to play.

S3 mini only have 1gb of ram, Lenovo have 512mb of ram. All other specifications are 90% same (gpu,cpu).

2.) Yesterday I tried to run my android game direct on Lenovo, using Android SDK, to direct test have my phone can play simple test game. And after engine finish to develop all files to Lenovo - It starts, but I have just blank screen, nothing like that:

ADB devices TEST see my phone, UE engine see my phone.

Is there only problem that my Lenovo is to weak for SDK testing and runing complexed games?

Oh, so far now, Epic Citadel works on high performance, but some security application crash game…I hate Lenovo :mad:

I will install different launcher (NOVA) on phone, maybe than will works launching game from engine to phone.

And it works now on Lenovo, I dont know why yesterday didnt work, but now is everything ok.

Only low graphic, but hey - I have time to make this better.

I dont get it - why psyhic and gravity is different in my mobile preview then in UE engine?
