Well in my case it is opposite, I have deleted all social media apps and other useless pre-installed apps as i do not use them, currently the available ram on my phone is 5-5.2 gb . Smooth GUI, no lag or hang. It's been almost 1 week so unable to provide comprehensive review as i am still discovering new features which my previous phone did not have. What impresses me is the battery performance, quick charge and very low battery drain. You can also chat on whats app while playing games at a same time (a miniature whats app window can be open to see any unread messages). super fast 4G speed, built-in screen recording & call recording etc etc (previously I was using P8 lite for almost 4 years so everything seems new and very fast to me.)
My cousin and few of my friends also bought Realme 5 (4gb/64gb) model and they are very much satisfied with specs & build quality. I must say you should go for it or if you have any doubts, check the reviews on YouTube and also physically inspect the phone before purchasing it.
The camera quality is awesome as well, wide angle pictures, night mode, Ultra 48mp photo-shoot, record 4K videos etc.
anything else you want to know, feel free to ask.
9.8 hours of gaming hahahahaha
