i have a micromax A73.with your wonderful guidance i have rooted my phone with ease. but after rooting my device , i am having some kind of problems like
1) i think the display resolution has changed because the wallpapers that appeared perfectly on my home screen now(after root) appears bigger and spreaded. can it be due to root??? plz help me out on this....
2) when my phone is straight and i type i cant press the 'q' key . and when i tilt it sideways i cant press the spacebar key......
one of the suggestions i got was of factory reset but it didn't help...the problem persists please help me out.......
