so i ordered my standard makerphone kit with tools through a polish distrubuter(since i live in poland)and a 4inch spi screen and i tought about upgrading the size of the screen from 128160 to 320240 and a bigger battery and i wouldnt use the gsm module alot but i will use it if i forgot my phone or even if i have my phone
Hey,
The idea is good, however, every Ringo app has been specifically made for this 128x160 screen size and things would have to be completely re-worked for anything different, so it is a no-go.
For the battery - no problem, bigger batteries of the same type should work normally, it’s just a questions whether you’ll be able to insert them inside of the phone. 
Keep in touch if you plan to make any progress on this!

oh well atleast its not makerbuino resolution and i could try to write something so it scales up to 320*240
and i could design my own case incase i want to add a bigger battery or any other mods im also thinking of making the ringo into a small computer and porting cp/m if it wasnt already ported to c
i could also reprogram the number pad so it haves numbers and letters im actually going to start coding a app or game for ringo on my lenovo laptop
It should be no issue get a bigger screen and write some code for it. However, you should be aware of the physical limitations of ESP32 and the amount of RAM - you might not be able to get a very high frame rate on much bigger screens.
This is quite an interesting field and a lot can be done by using many different algorithms, so I suggest that you explore it a bit more if you find it fun since a lot can be learned here.
All of this should be a very fun project - feel free to reach out if you need any specific details about the phone!
And of course - keep us updated!

yes i am aware but 512kb should be enough for a decent game and i even tho i wrote a game on scratch i couldnt get a single cube to move left and right on circuitblocks language im going to need to actually learn how to use circuitblocks to write a simple platformer and as im aware there are dip 8 sram chips that with small tweak i could get 590k but creating a os in circuitblocks will take some time but the esp controller atleast is faster then atmega328 chip and 160-280mhz should and the stock spead is close to intel 486 bec it runned 150 mhz to 160 mhz im refering to the adz version
