Chosen Solution

Whenever I play mobile legends in my BLU phone (sorry forgot the model) , I can’t possibly move the control stick while using the other buttons in the other side of the phone. This also applies with the other games in my phone like ppsspp and even my Google map. Honestly I have a really hard time zooming in and out on my Google map. Update (11/08/2017) It’s R1 plus BTW, the model of my phone.

They came out with a software update that fixes this issue. Go to Settings, About Device, System Updates. Once you load the latest update it allows you to use multi-touch features like zooming maps or playing games.

I had the same issues but what I’ve figured out while setting PPSSPP emulator and it worked for me: First, make sure to use the Vulkan, it has been added recently, and it works amazingly:

For average hardware smartphone, Buffer Rendering works good. Otherwise, select the “Non Buffer rendering”

Then, enable all the Performance hacks under this menu expect, “Retain Changed texture”

Then setup controls according to your needs. Moving next, under the System->Emulation, make sure to use Change emulated PSP’s CPU clock (unstable), use the maximum available value available. This will boost the performance on many games.

For rest of the settings, you can try yourself or following the below guide: https://techshali.com/best-setting-ppssp… Hopping for better results!
