Are the screen/digitizers on Stylo 5 & Stylo 4 interchangeable?

Yes you most definitely can I have the same issue I had a Stylo 5 with a broken screen and I had three or four Stylo 4s with great brand new screens on them I even changed out the charging ports as well on the Stylo 5 stopped working and I managed to take one of the style 4s and it's a little bit different but you can finagle it to work in the style 5 and fit it in with no problem you just have to modify it a little bit. one part of the circuit charging port circuit board you have to kind of heat it up and bend the circuit strip and it fits perfectly as far as the screen goes you most definitely can put a Stylo 4s screen on a Stylo 5 they're identical the only difference between the phones is the batteries and the frames the frames are slightly different like where the power button is the Stylo four power button is much bigger on the inside versus the stylo 5 which is about half the size and thickness which you can modify that as well most of the parts are interchangeable the real only difference is you can't interchange the batteries because the stylo 5 requires a slightly higher voltage even though it's on the milliamp side it still will@burn the circuit board out it's still slightly bigger and higher than the stylo 4s and the stylo 4s battery is only 3300 ma which the stlyo 5s battery is 3500ma which you wouldn't think being that big of a deal but it's enough to cause damages to the circuit board especially cuz it's so tiny and they're very very sensitive but yeah you can interchange the screens I'm actually in the process of doing the same. Just be careful getting that good screen off the Stylo 4 you going to have to take the entire phone apart down to the frame so I take the back off take the battery out take the charging port out along with the speaker next to it you want to take out everything you possibly can the circuit board down to the frame and basically the screen on the front cuz you're going to have to heat it up pretty hot with a hot air gun. A hair dryer may not get it hot enough but if you have a strong enough hair dryer you could do it if you have a hot plate that will work too but you'll have to put like something between the screen and the hot plate so you don't crack it because it gets too hot it could crack the screen the screen is glass which in turn would take quite a high temperature to melt but could still damage the liquid crystal inside the screen which is the digitizer so just take your time be patient you're going to need some special tools like really really thin pieces of stainless strips that you can wedge under to work it and you're going to want to work it on the top of the bottom don't work it from the side too long sides cuz that's where it will tend to crack easier you want a shorter distance on the top left to right or the bottom of the glass and you want. Small@suction cups. At least 2 min. try pretty gently prying once it is to hot to touch you can get a thin pry sticks in some of the holes in the back once it's hard enough heat and you can release the glue that way that's how they do it in the factory but most of the time they just replacing it and they don't care if they break it and they're just clean it out after once it breaks that just pull the little pieces out but you're trying to get it out and reuse it without buying another one but a little FYI it actually is not that expensive for another screen it's less than $10 good luck if you need any help just reach out again on this out
