Kids are very creative these days, so one way or the other, they will find their way [emoji1].
Then you need water resistant phone too, like Galaxy S5, Moto G3 etc. They have Gorilla Glass and water resistance both [emoji14].
Lenovo phones are very good overall and offer 12 months local warranty with 6 months battery warranty. Lenovo had some problems with their A series phones, but others were very good, better than Infinix. I still have many friends having Lenovo phones and having no troubles at all.
Lenovo has provided protective cover and screen protector in box and even provided USB OTG cable with some models. Lenovo is great choice for those wanting exceptional battery timings, as many of their phones have very large batteries. They even work as power banks to charge other phones.
Lenovo phones camera is good, but not very good, and their stock launcher looks too cheap. That's the drawbacks i noticed.
Comparing Lenovo Vibe P1m (4G) with P70 (4G), P70 is a lot better, except for
P1m has better display quality.
P1m has nano coating (slightly water resistant).
Both have only auto rotation, proximity, auto brightness sensors and GPS, but they lack compass.
