Relatively good phone but there are better options

I had previously bought the dual sim version of this phone for my mom (we'll get to why that's important later) and it worked pretty well for some time. It has relatively good features and build quality for the price however it started developing the 'ghost touch' issue along with several other bugs including random shutdowns when receiving calls. Unfortunately she only let me know this after I had already bought one for my dad to replace his older phone that got trashed. I recently got his phone and I'm hoping it's better than my mom's. Now on to the part about the dual sim version, I used the exact same link from the previous purchase and all the information was exactly the same except that I didn't realise it did not say Dual Sim as before. It's pretty sneaky how these sellers (or I don't know if it's Amazon) that just bundle functionally different products together it's very confusing. I hope this phone at least doesn't have the issues like the previous one.
