Hi, everyone!
I had to flash my phone because one day it got stuck in the boot logo. I didn't have the ROM backed up since I was not planning to mess with the phone's software in any way.
I own a Star N800+. Sadly, I couldn't find a suitable ROM anywhere. So I followed @cybermaus ' advice (find a ROM for a phone that has same processor, same memory, same buttons, same screen type and resolution, same sensors, same camera -- http://forum.xda-developers.com/showthread.php?p=36326293#post36326293) and decided that Star/Ulefone N9770 had to have the same hardware. So I flashed a couple of ROMs for N9770 into my N800+ and each one worked great (that is, camera, gps, wifi, g-sensor, buttons where all working) but the screen was rotated upside-down. I mean, every single thing that gets diplayed on the phone from boot logo, to android menu, to every app, to the image from the camera are shown rotated upside-down but in order to operate the phone you have to tap as if you were viewing it right. For example, to tap on the upper-left corner of the image you have to tap on the lower-right corner of the phone's display.
Mi guess is that even if both phones may have the same hardware, there should be some parameters that are not the same for both models. Could anyone, please, give me a hint on this matter?
Here is my phone info:
Star N800+
MT6577 processor,
bootloader came unlocked from factory,
Android version e1909c_v77_jbl_9p017_6628
Baseband version MAUI.11AMD.W12.22.SP.V15
Camera Aptina A-pix MT9p017
Build.prop settings

this link shows the same problem on galaxy s2
So I tried to update my android's headunit firmware to JY-1.90 and now my screen is cut-off on the right and bottom side. My headunit's screen resolution was 800x480 and now it is 1024x600. Tried to change my resolution with a program (i have root access) but after changing the resolution the screen is still cutoff. As you can see in the video the touch is spot on like it should be but the display isnt.
Will try to post a video. What can I do to fix it?
Hello
I just replaced the touch screen of my generic 9inch Android Tablet running on Jelly Bean. I couldn’t get the genuine one so I just bought a compatible one: The screen works BUT it doesn’t properly map the co-ordinates on the Display. Bottom and the sides are OK but the top (about 1 inch in landscape mode) has no response. The screen is all working : The bottom matches fine but as you swipe upwards you can see that your finger touches a higher point which matches a slightly lower point on the display. When your finger reaches the top …the matching map becomes about 1inch bellow on the display.
I need help to fix this issue: I think there would be a file inside my android where there would be values to match the Display Screen mapping with the Touch Screen (digitizer)
Thank you in advance……
I want to set the resolution to 1920*1080, everything works, but when changing the resolution, the corners of the interface remain rounded. Also, a stripe appears from below, below the gesture stripe. Can you tell me what system settings to change so that the angles are straight? Pixel Expirience Android 12. Magisk is installed.
The phone has a 2400 x 1080 pixel screen format. If you enter 1920 x 1080, you won't fill the entire screen and you'll get an unused border bar.
you need to modify the system
